Description

Communication method and equipment Technical field

The present invention relates to the field of communication, in particular to a communication method and equipment.

Background technique

In a wireless network, terminal equipment may communicate with multiple access network equipment, that is, dual connectivity (Dual Connectivity, DC), also known as MR-DC (Multi-Radio dual connectivity), multiple access network equipment can belong to the same The system can also belong to different systems. In the dual-connection scenario, in order to detect and optimize the problems and failures in the wireless network, the access network device needs to send the measurement configuration to the terminal device.

The basic idea of Minimization of Drive-Tests (MDT) is that operators use commercial terminals of contracted users to perform measurement and report to partially replace traditional drive tests, and to automatically collect terminal measurement data to learn network performance. , And detect and optimize the problems and failures in the wireless network. MDT includes logged MDT and immediate MDT. Immediate MDT is mainly for the measurement of terminal equipment in the radio resource control (Radio Resource Control, RRC) connected state (RRC_CONNECTED), and logged MDT is mainly for the measurement in the idle state (RRC_IDLE) or RRC Measurement performed by the terminal device in the inactive state (RRC_INACTIVE).

For some streaming services or voice services or other services, the signal quality alone cannot reflect the user experience when users use these services. Operators measure the Quality of Experience (QoE) according to the measurement report. Optimize the network to improve the quality of user experience.

Since multiple access network devices provide services for the terminal device, the maximum number of measurement configuration sets that the terminal device can receive is related to the number of access network devices it serves (for example, the first access network provides services to the terminal device). A set of MDT measurement configuration is sent, and the second access network device also sends a set of MDT measurement configuration to the terminal device. In this case, the terminal device receives two sets of MDT measurement configuration). When multiple access network devices that provide services to the terminal device send the same type of measurement configuration to the terminal device, coverage between the measurement configurations may occur, and the terminal device will delete the measurement results obtained from the previous measurement configuration, resulting in Measure the waste of overhead.

In an optional manner, the primary base station in the embodiment of the present application may be an NR base station connected to a 5G core network, and the secondary base station is an LTE base station.

Fig. 1 exemplarily shows a network architecture diagram of a possible communication system. The architecture diagram includes a core network device 100, at least one primary base station 110 connected to the core network device 100 (only one primary base station is shown in Figure 1), and at least one secondary base station 120 connected to the primary base station 110 (Figure 1 Only one secondary base station is shown), and one or more terminal devices 130 connected to the primary base station 110 and the secondary base station 120. There is a control plane connection between the core network device 100 and at least one primary base station 110. The core network device 100 may have a user plane connection with at least one secondary base station 120.

In the embodiments of the present application, it can be divided into the following optional methods to introduce the interface between the core network device and the main base station.

An optional way, in the 5G core network scenario, the main base station 120 (5G base station) and the core network equipment (for example, access and mobility management function (AMF)) 100 The interface is an NG interface, and the control plane of the NG interface may be called an NG control plane (NG-C).

In an optional manner, in a 4G core network scenario, the interface between the main base station 120 (4G base station) and the core network device (for example, a mobility management entity (MME)) 100 is an S1 interface.

It should be understood that a wireless Uu interface is established between the primary base station and the terminal equipment, which can transmit user plane data and control plane signaling with the terminal equipment. At the same time, a Uu interface can also be established between the secondary base station and the terminal equipment to communicate with the terminal equipment. The terminal equipment transmits user plane data and control plane signaling, that is, the terminal equipment is in a dual connectivity architecture mode (Dual Connectivity, DC), and both the primary base station and the secondary base station can provide services for the terminal equipment. It can be understood that FIG. 1 is only an exemplary network architecture diagram, and the network architecture also includes other network element devices or functional units, which are not limited in this application.

Based on the communication system shown above, FIG. 2 is a schematic flowchart of a communication method 200 according to an embodiment of the present application. The technical solutions of the embodiments of the present application will be described in detail below with reference to FIG. 2 in the embodiments of the present application. Exemplarily, the first access network device is the primary base station and the second access network device is the secondary base station as an example below. The communication methods corresponding to Figure 2 include:

In an embodiment of the present application, the terminal device will report capability information supporting measurement configuration, which may include operation 201.

Operation 201: The terminal device sends third indication information to the primary base station.

The third indication message carries the capability information of the measurement configuration supported by the terminal device. Optionally, the capability information may be whether the terminal device supports the measurement configuration. Further, if the measurement configuration is supported, it may also include supporting several sets of measurement configurations. It can also be the format information that supports the measurement configuration. For example, the third indication information indicates that the terminal device can only support one set of MDT measurement configurations, or that the terminal device can only have one set of MDT measurement configurations at the same time. It is understandable that the third indication information can also indicate that the terminal device can support two sets MDT measurement configuration (the two sets of MDT measurement configuration may be the MDT measurement configuration of the NR standard and the MDT measurement configuration of the LTE standard, or may not distinguish between the standards), or indicate that the terminal device can have two sets of MDT measurement configurations at the same time, and the terminal device The third indication information can be transmitted through Uu interface messages. Optionally, the MDT measurement includes logged MDT measurement.

Among them, operation 201 is optional.

Operation 202: the primary base station determines that only one set of measurement configuration can be sent to the terminal device.

In the embodiment of this application, it can be specifically divided into the following optional methods to introduce how the master base station determines that only one set of measurement configuration can be sent to the terminal device:

An optional method: the main base station determines according to the third indication information sent by the terminal device in operation 201. For example, the third indication information indicates that the terminal device can only support one set of measurement configurations, or indicates that the terminal device can only have one measurement configuration at the same time. Set of MDT measurement configuration.

An optional method: the agreement stipulates that only one set of measurement configuration can be sent to the terminal device, or the agreement stipulates that the terminal device can only support one set of measurement configuration or the terminal device can only have one set of MDT measurement configuration at the same time.

It should be understood that the terminal device can only support one set of measurement configuration and the protocol stipulates that only one set of measurement configuration can be sent to the terminal device. When either of these two situations occurs, the main base station can determine that only one set of measurement configuration can be sent to the terminal device. Set of measurement configurations.

In another embodiment of the present application, operation 202 can also be replaced with: the primary base station determines the number of measurement configurations that can be sent to the terminal device, then the primary base station sends the first configuration number information to the terminal device, indicating the measurement that the terminal device can receive The number of configurations. In an optional manner, the primary base station determines the number of measurement configurations that can be sent to the terminal device according to the third indication information sent by the terminal device in operation 201. For example, the terminal device supports receiving two sets of measurement configurations, but the main base station only wants to configure one set of measurement configurations for the terminal device. In an optional way, the master base station determines the number of measurement configurations that the terminal device should receive. When the first configuration number information sent by the master base station to the terminal indicates that the number of measurement configurations that can be received by the terminal device is N, when the number of configurations received by the terminal device is less than or equal to the number N, the terminal device will not perform any measurement configuration. Between coverage. When the number of configurations received by the terminal device is greater than the number N, the terminal device can perform coverage between various measurement configurations (for example, the measurement configuration received last covers the measurement configuration received first).

In another embodiment of the present application, before or after operation 202, the secondary base station sends request information to the primary base station for requesting that the measurement configuration can be sent to the terminal device. The operation may also include operation 203. The order of operation 203 is not limited.

Among them, operation 202 is optional.

Operation 203: the secondary base station sends the first request information to the primary base station.

The first request information is used by the secondary base station to request the primary base station to request the secondary base station to be able to send the measurement configuration to the terminal device. The measurement configuration includes MDT measurement configuration and/or QoE measurement configuration. Optionally, the MDT measurement includes logged MDT measurement.

Optionally, for signaling-based logged MDT or QoE measurement, when the secondary base station receives the UE’s logged MDT or QoE measurement configuration information from the primary base station, and the secondary base station selects the terminal device for logging MDT or QoE For measurement, the secondary base station sends the first request information to the primary base station; for management-based logged MDT or QoE measurement, when the secondary base station receives management from the operation administration and maintenance (OAM) (or called network management) entity MDT measurement configuration, and the secondary base station selects the terminal device to perform logged MDT or QoE measurement, the secondary base station sends the first request information to the primary base station; the information exchange between the primary base station and the core network can be carried out through the interface between the two, For example, NG interface or S1 interface.

As for the way that the secondary base station selects the terminal device to perform logged MDT or QoE measurement, there are several ways:

In an optional manner, for signaling-based logged MDT measurement, if the terminal device supports logged MDT measurement of the secondary base station standard, the secondary base station selects the terminal device to perform signaling-based logged MDT measurement. Further, in the case that the terminal equipment supports logged MDT measurement, if the message from the primary base station to the secondary base station carries information about the area range of the secondary base station corresponding to the RAT, the secondary base station can also determine whether to select the terminal according to the area information sent by the primary base station The device performs logged MDT measurement. For example, if the cell accessed by the secondary base station belongs to the area, the secondary base station selects the terminal device to perform signaling-based logged MDT measurement.

In an optional manner, for the management-based MDT measurement, if the terminal device supports the logged MDT measurement of the secondary base station standard, the secondary base station selects the terminal device to perform the management-based logged MDT measurement. Further, in the case that the terminal device supports logged MDT measurement, if the logged MDT measurement configuration obtained by the secondary base station from OAM carries information about the area range of the secondary base station, the secondary base station can also determine whether to select the terminal according to the area information sent by the OAM The device performs logged MDT measurement. For example, if the cell accessed by the terminal device falls within the area, the secondary base station selects the terminal device to perform management-based logged MDT measurement. Further, the secondary base station will determine whether to select the terminal device based on the management-based MDT PLMN list (management-based MDT PLMN list) and/or the management-based MDT measurement allowed (management-based MDT allowed) sent by the primary base station to the secondary base station. Logged MDT measurement. For example, if the secondary base station receives management based MDT allowed, then the secondary base station can select the cell accessed by the terminal device to perform management-based logged MDT measurement.

In an optional manner, for signaling-based QoE measurement, if the terminal device supports QoE measurement, the secondary base station selects the terminal device to perform signaling-based QoE measurement. Further, in the case that the terminal equipment supports QoE measurement, if the message from the primary base station to the secondary base station carries information about the area range of the secondary base station, if the cell accessed by the terminal equipment in the secondary base station belongs to the area range, the secondary base station selects The terminal equipment performs signaling-based QoE measurement.

In an optional manner, for management-based QoE measurement, if the terminal device supports QoE measurement, the secondary base station selects the terminal device to perform management-based QoE measurement. Further, in the case that the terminal device supports QoE measurement, the secondary base station can also determine based on the area range information sent by OAM. If the cell accessed by the terminal device in the secondary base station belongs to the area range, the secondary base station selects the terminal device for Managed QoE measurement. Further, the secondary base station will determine whether to select the terminal device based on the management-based MDT PLMN list (management-based MDT PLMN list) and/or the management-based MDT measurement allowed (management-based MDT allowed) sent by the primary base station to the secondary base station. QoE measurement. For example, if the secondary base station receives management based MDT allowed, the secondary base station can select the cell accessed by the terminal device to perform management-based QoE measurement.

Among them, operation 203 is optional.

Operation 204: the primary base station determines whether the secondary base station can send the measurement configuration to the terminal device.

In the embodiments of this application, it can be specifically divided into the following optional methods to introduce how the primary base station determines whether the secondary base station can send the measurement configuration to the terminal device:

An optional method: If operation 202 is included, the primary base station determines that only one set of measurement configuration can be sent to the terminal device, and negotiation is initiated between the primary base station and the secondary base station. The primary base station has the right to make measurement configuration decisions, and the primary base station determines the secondary base station. The measurement configuration can be sent to the terminal device. It should be understood that the primary base station may also determine that the secondary base station cannot send the measurement configuration to the terminal device

An optional way: if operation 203 is included, the primary base station agrees to the first request information in operation 203 and determines that the secondary base station can send the measurement configuration to the terminal device. It should be understood that the primary base station may also disagree in operation 203. The first request information for determining that the secondary base station cannot send the measurement configuration to the terminal device.

An optional way: if operation 203 is not included, the primary base station autonomously decides that the secondary base station can send the measurement configuration to the terminal device. It should be understood that the primary base station may also determine that the secondary base station cannot send the measurement configuration to the terminal device.

It should be noted that the above are only a few optional methods, and other methods can also be adopted, and the present invention does not make specific limitations.

Optionally, for the above methods, signaling-based logged MDT or QoE measurement, when the primary base station receives the logged MDT of the terminal equipment from the core network equipment or the previous primary base station (ie, the source base station in the handover scenario) Or QoE measurement configuration information, the primary base station can determine that the secondary base station can send the logged MDT or QoE measurement configuration to the terminal device; for management-based logged MDT or QoE measurement, when the primary base station is from the core network or the previous primary base station (ie When the source base station in the handover scenario receives that the terminal device can perform management MDT measurement (for example, the main base station receives management-based MDT allowed information from the core network or the primary base station before the handover), the primary base station can determine The secondary base station can send the logged MDT or QoE measurement configuration to the terminal device.

In another embodiment of the present application, if operation 204 determines that the secondary base station cannot send the measurement configuration to the terminal device, operation 209 may also be included. That is, the primary base station does not notify the secondary base station whether the secondary base station can send the measurement configuration to the terminal device. The base station sends the measurement configuration directly to the terminal device.

Operation 205: the primary base station sends the first indication information to the secondary base station.

According to operation 204, after the primary base station decides whether the secondary base station can send the measurement configuration to the terminal device, the primary base station may send first indication information to the secondary base station, the first indication information indicating whether the secondary base station can send the measurement configuration to the terminal device.

It should be noted that the primary base station can immediately send the first indication information to the secondary base station after determining whether the secondary base station can send the measurement configuration to the terminal device, instructing the secondary base station to send the measurement configuration to the terminal device, or it can determine whether the secondary base station can send the measurement configuration to the terminal device. After a period of time after the measurement configuration is sent to the terminal device, the first indication information is sent to the secondary base station, which is not limited in this application. Of course, the first indication information may also carry an indication time and an indication period to indicate whether the secondary base station can send the measurement configuration to the terminal device at a specified time or indication period.

In the embodiments of the present application, it can be specifically divided into the following optional methods to introduce the implementation manner of the primary base station sending the first indication information to the secondary base station:

In an optional manner, the first indication information may be sent by the secondary station addition request information (SeNB/SgNB Addition Request), that is, the primary base station carries the first indication information in the SeNB/SgNB Addition Request message. For example, when the value of the first indication information is 0, it indicates that the secondary base station can send the measurement configuration to the terminal device, or when the field value is 1, it indicates that the secondary base station can send the measurement configuration to the terminal device. The meaning of the specific value of the field is not limited, as long as the secondary base station can learn the decision of the primary base station, so that the secondary base station can receive the first indication information of the primary base station during the process of establishing a connection between the terminal device and the secondary base station.

In an optional manner, the first indication information may be sent through a secondary station modification request (SeNB/SgNB Modification Request) message, that is, the primary base station carries the first indication information in the SeNB/SgNB Modification Request message. For example, when the value of the first indication information is 0, it indicates that the secondary base station can send the measurement configuration to the terminal device, or when the field value is 1, it indicates that the secondary base station can send the measurement configuration to the terminal device. This application is not limited .

In an optional manner, the first indication information may be an explicit indication message, that is, the first indication information is specifically used for a field of the primary base station's decision on whether to send the measurement configuration to the secondary base station to the terminal device. For example, at least one bit may be used to explicitly indicate whether the secondary base station sends the measurement configuration to the terminal device. For example, when this field is 1, it indicates that the secondary base station sends the measurement configuration to the terminal device, or when the field is 0, it indicates that the secondary base station does not send the measurement configuration to the terminal device. The device sends the measurement configuration, or when this field is 1, it indicates that the secondary base station does not send the measurement configuration to the terminal device. The embodiment of this application does not limit the meaning of the specific value of the field, as long as the secondary base station can learn the primary base station’s Just make a decision. It can also be that the primary base station only sends the first indication information to the secondary base station when the primary base station decides that the secondary base station sends the measurement configuration. If the secondary base station does not receive the first indication information, it indicates that the secondary base station is instructed not to send the measurement configuration to the terminal device, and vice versa. .

It is understandable that, it is also possible to indicate to the secondary base station whether to send the measurement configuration to the terminal device in an implicit manner. Optionally, the first indication information indicates that the primary base station determines that it will send the measurement configuration to the terminal device or instructs the primary base station to send the measurement configuration to the terminal device, then the secondary base station is implicitly instructed not to send the measurement configuration to the terminal device. Another optional implicit method is that the first indication information is measurement configuration information. For example, the primary base station carries MDT measurement or QOE-based configuration information or the managed MDT PLMN list (management based MDT) through the first indication information. PLMN list) and/or management based MDT allowed, that is, implicitly indicating that the secondary base station can send the configuration information of the measurement to the terminal device.

In most actual measurement scenarios, the measured area range will be clarified. Optionally, the first indication information can carry area range information. It is understandable that the above area range information can also be sent to the secondary base station in other ways, such as The foregoing area range information is sent through other fields in the message including the first indication information, or the foregoing area range information is sent through other messages, which is not limited in the embodiment of the present application. The following examples introduce the area range carried by the first indication information.

In a possible design, for signaling-based MDT measurement, the primary base station will take the MDT PLMN list (signalling based MDT PLMN) received from the core network or the previous primary base station (that is, the source base station in the handover scenario). list) and/or the MDT area range is sent to the secondary base station through the first indication information. Optionally, if the MDT area range received by the primary base station from the core network or the previous primary base station (ie, the source base station in the handover scenario) is not related to the secondary base station (for example, the MDT area range is only related to the primary base station), then An indication message does not carry the area range. For management-based MDT measurement, the master base station will receive the management-based MDT PLMN list (management-based MDT PLMN list) and/or received from the core network or the previous master base station (that is, the source base station in the handover scenario). The management based MDT allowed is sent to the secondary base station through the first indication information. Optionally, when the primary base station receives the MDT area range of the secondary base station's radio access technology (Radio Access Technology, RAT) from the operation and maintenance management entity, (for example, the area range information is the cell global identity of the secondary base station corresponding to the RAT, Tracking area code), the primary base station sends the relevant configuration of the area range to the secondary base station through the first indication information. Optionally, if the MDT area range received by the primary base station is not related to the secondary base station (for example, the MDT area range is only related to the primary base station), the first indication information does not carry the area range.

It is understandable that the signaling-based QoE measurement is similar to the above-mentioned carrying manner, except that the area range information is the QoE measurement range.

In another embodiment of the present application, if the first indication information in operation 205 indicates that the secondary base station cannot send the measurement configuration to the terminal device, operation 209 may also be included. That is, the primary base station sends the first indication information to notify the secondary base station that the measurement configuration cannot be sent to the terminal device, and the primary base station determines to send the measurement configuration to the terminal device. It should be understood that, in this embodiment, the order of operation 205 and operation 209 is not limited. Optionally, the main base station may immediately send the measurement configuration to the terminal device, or may send the measurement configuration to the terminal device after a period of time after determining the sending of the measurement configuration to the terminal device, which is not limited in this application.

In another embodiment of the present application, if the first indication information in operation 205 indicates that the secondary base station can send the measurement configuration to the terminal device, operation 208 may also be included, that is, the secondary base station receives that it can send the measurement configuration to the terminal device. After the first indication information, the secondary base station directly agrees with the indication information of the primary base station and determines to send the measurement configuration to the terminal device. Optionally, when the secondary base station sends the measurement configuration to the terminal device is further decided by the secondary base station. Optionally, in a case where the terminal device supports the measurement configuration, operation 208 is performed. Optionally, when the terminal device does not support the measurement, the measurement configuration is not sent to the terminal device. In order to avoid repetition, how to determine whether the terminal device supports the measurement configuration, please refer to the related introduction of determining whether the terminal device supports the measurement configuration capability in operation 206.

Operation 206: the secondary base station determines whether to send the measurement configuration to the terminal device.

After receiving the first indication information sent by the primary base station in operation 205, the secondary base station further decides whether to send the measurement configuration to the terminal device. In the embodiment of the present application, it can be specifically divided into the following optional methods to introduce how the secondary base station further determines whether to send the measurement configuration to the terminal device.

In an optional manner, the first indication information indicates that the secondary base station can send the measurement configuration to the terminal equipment. Further, the secondary base station independently decides whether to send the measurement configuration to the terminal equipment, that is, after receiving the first indication information, the secondary base station can select Send the measurement configuration to the terminal device, or you can choose not to send the measurement configuration to the terminal device. Further, the secondary base station can also determine when to send the measurement configuration to the terminal device.

In an optional manner, the first indication information indicates that the secondary base station cannot send the measurement configuration to the terminal device, and the secondary base station determines not to send the measurement configuration to the terminal device.

In an optional manner, the first indication information indicates that the secondary base station can send the measurement configuration to the terminal device. Further, the secondary base station determines whether to send the measurement configuration to the terminal device according to the ability information of the terminal device to support the measurement configuration. For example, for signaling-based MDT measurement, if the terminal device supports MDT measurement, the secondary base station determines to send the signaling-based MDT measurement configuration to the terminal device. Further, in the case that the terminal device supports the MDT measurement configuration, if the first indication information carries information about the area range of the secondary base station, the secondary base station can also determine according to the area information of the MDT measurement sent by the primary base station, for example, if the terminal device is connected If the incoming cell belongs to the MDT measurement area, the secondary base station sends the signaling-based MDT measurement configuration to the terminal device.

Operation 207: In operation 206, the secondary base station makes a decision on whether to send the measurement configuration to the terminal device, and the secondary base station sends second indication information to the primary base station. The second indication information indicates the result of the decision in operation 206, and the secondary base station can pass X2/Xn interface message to transfer the second indication information.

In another embodiment of the present application, if the second indication information in operation 207 indicates that the secondary base station determines not to send the measurement configuration to the terminal device, operation 209 may also be included. That is, the secondary base station sends the second indication information to the primary base station, and determines that the secondary base station does not send the measurement configuration to the terminal device, then the primary base station may send the measurement configuration to the terminal device.

In another embodiment of the present application, if the second indication information in operation 207 indicates that the secondary base station determines to send the measurement configuration to the terminal device, operation 208 may also be included. That is, the secondary base station sends the second indication information to the primary base station to instruct the secondary base station to determine to send the measurement configuration to the terminal device, and the primary base station determines that the secondary base station sends the measurement configuration.

Among them, operation 207 is optional.

Operation 208: the secondary base station sends the measurement configuration to the terminal device.

Specifically, the secondary base station can transmit measurement configuration information through Uu interface messages (for example, the secondary base station can first send these measurement configurations to the primary base station, and then the primary base station sends it to the terminal device; or the secondary base station directly sends it to the terminal device).

Optionally, for signaling-based MDT measurement, the secondary base station may send the signaling-based MDT PLMN list (signalling-based MDT PLMN list) and/or the cell global identity or tracking area code in the MDT area To the terminal equipment.

Optionally, for management-based MDT measurement, the secondary base station may send the management-based MDT-based PLMN list (management-based MDT PLMN list) and/or the cell global identity or tracking area code in the MDT area to the terminal equipment.

It should be noted that in this application, the secondary base station may send the measurement configuration to the terminal device immediately after determining to send the measurement configuration to the terminal device, or it may send the measurement configuration to the terminal device after the secondary base station determines to send the measurement configuration to the terminal device for a period of time. The configuration is not limited in this application.

In another embodiment of the present application, the network manager may need the type information of the terminal device corresponding to the measurement result (exemplarily, the manufacturer of the terminal device, the type of the terminal device, etc., such as the International Mobile Equipment Identity Type Allocation Code (IMEI type allocation code) code,IMEI-TAC)). For example, for management-based MDT measurement, the network management or tracking collection entity TCE, based on the type information of the terminal device obtained, combined with the management-based MDT measurement result of the terminal device, analyzes the type information of the terminal device involved in the measurement result. Corresponding to the performance of such terminal equipment under the network. When the secondary base station receives the management-based MDT measurement configuration from the network management, the secondary base station determines to send the measurement configuration to the terminal device. It should be noted that the situation in which the secondary base station determines to send the measurement configuration to the terminal device in this embodiment includes the determination after negotiation with the primary base station, and also includes the secondary base station autonomously determining to send the measurement configuration to the terminal device. Further, this implementation introduces how the network management or tracking collection entity TCE obtains the type information of the terminal device. The network manager sends the management-based MDT measurement configuration information to the base station and carries the first network management indication information, indicating whether to obtain the type information of the terminal device (for example, whether to send the type information of the terminal device to the TCE). The first network management indication information may be display indication information (for example, MDT data anonymization indication, the value may be an enumerated type, the value may be no identification, or TMEI-TAC is required), or it may be implicit indication information. The application embodiment does not limit the specific bearing mode of the first network management indication information, as long as the base station can learn whether the network management or tracking collection entity TCE requires terminal device type information. It should be noted that the tracking collection entity TCE in all the embodiments of this application may be other entities, that is, the base station may send the measurement results to other entities.

When the first network management indication information indicates that the network management or tracking collection entity TCE requires terminal equipment type information, the secondary base station may send the first request indication information to the primary base station through the interface (for example, X2 or Xn interface) with the primary base station. The indication information may be a privacy indicator (privacy indicator). For example, when the management-based MDT measurement configuration information sent by the network management to the secondary base station indicates that the current configuration information is immediate MDT configuration information, the first request indication information takes the value of immediate MDT measurement; when the network management sends the management-based measurement to the secondary base station When the MDT measurement configuration information indicates that the current configuration information is logged MDT configuration information, the value of the first request indication information is logged MDT measurement. For example, the secondary base station may send the first request indication information through the secondary base station modification required message (S-NODE modification required or SgNB modification required). Further, when the secondary base station sends the first request indication information to the primary base station, it can also carry the trace recording session reference (Trace Recording Session Reference), the trace reference (Trace Reference), and the global cell identification of the serving cell of the terminal (cell global identification). ,CGI), track at least one of the IP addresses of the collecting entity. Optionally, the secondary base station may send the first request indication information to the primary base station after receiving the MDT measurement result of the terminal device, and may also send the first request indication information to the primary base station at other times.

Further, after the primary base station receives the first request indication information sent by the secondary base station, the primary base station interacts with the control plane signaling of the core network equipment (for example, the cell service tracking sent by the base station to the core network in the S1 or NG interface) The message cell traffic trace) sends the second request indication information to the core network device. The indication content of the second request indication information and the first request indication information may be the same. After that, after the core network device receives the second request indication information, it will look up the type information of the terminal, and send the type information of the terminal device to the network management or tracking collection entity TCE. When the first request indication information indicates that the terminal device identifier is not required, the secondary base station does not need to send the second request indication information to the primary base station, that is, the network management or the tracking collection entity TCE does not need to know the type information of the terminal device. It should be noted that in this embodiment, the situation where the secondary base station requests the primary base station/core network to report the terminal equipment type information to the tracking collection entity includes the situation where the primary and secondary base stations determine that the secondary base station sends the measurement configuration after negotiation, that is, the secondary base station determines After sending the measurement configuration to the terminal device, the process of reporting the terminal device type information to the network management or tracking collection entity TCE in this embodiment may be before operation 208 or after operation 208, which is not limited; it also includes that the secondary base station independently determines to send to the terminal device In the case of measurement configuration, that is, without negotiating with the primary base station, when the secondary base station autonomously determines to send the measurement configuration to the terminal device, it determines whether to request the primary base station/core network to report the type information of the terminal device according to the received first network management instruction information.

Operation 209: the primary base station sends the measurement configuration to the terminal device. Optionally, the primary base station can send the measurement configuration through a Uu interface message.

It should be noted that in this application, the main base station may send the measurement configuration to the terminal device immediately after determining to send the measurement configuration to the terminal device, or it may send the measurement configuration to the terminal device after the main base station determines to send the measurement configuration to the terminal device for a period of time. The configuration is not limited in this application.

After the terminal device receives the measurement configuration issued by the base station, the terminal device records the corresponding measurement result according to the corresponding measurement configuration. Generally, the terminal device also sends the measurement result to the base station, and the base station sends the measurement report to the Trace Collection Entity (TCE). The measurement report carries the measurement result and the radio access technology (Radio Access Technology) corresponding to the measurement result. Technology, RAT) information.

In another embodiment of the present application, if operation 208 or operation 209 sends the measurement configuration to the terminal device and the terminal device obtains the measurement result, it may also include operation 210 and operation 211. It should be noted that the base station may send the measurement result to the collecting entity immediately after receiving the measurement result, or may send it to the collecting entity after a period of time, which is not limited in this application.

Operation 210: the terminal device sends the measurement result to the base station (primary base station or secondary base station).

Optionally, the terminal device may send the measurement result to the main base station through the control plane bearer or the user plane bearer of the Uu interface, and at the same time may also transmit the RAT information corresponding to the measurement result through the Uu interface information.

In the embodiments of this application, it can be specifically divided into the following optional methods to introduce possible content of RAT information:

An optional way: the RAT information may be the RAT type information of the service bearer corresponding to the measurement result, for example, the service is carried in LTE, or the service is carried in NR, which is not limited by this application.

An optional way: the RAT information may be the type information of the access network device that issued the measurement configuration or received the measurement result (for example, NR base station or LTE base station);

An optional way: the RAT information may be the cell global identity of the serving cell.

Optionally, when the terminal device initiates a radio resource control (Radio Resource Control, RRC) connection to the primary base station, the terminal device may carry fourth indication information in the RRC message, and the fourth indication information indicates that the current terminal device has recorded the measurement result . Optionally, the fourth indication information may also indicate that the current terminal device has recorded a measurement result corresponding to the radio access technology corresponding to the secondary base station. After receiving the fourth indication information, the primary base station may send a request for measurement result recording to the terminal device, and the terminal device may send the measurement result to the primary base station after receiving the request. For example: when the terminal device initiates an RRC connection to the primary base station, the fourth indication information can be carried in the RRC Setup Complete (RRCSetupComplete) message to instruct the terminal device to record the measurement result, and then the primary base station carries it in the terminal equipment information request (InformationRequest) Fifth indication information, the fifth indication information instructing the terminal device to send the measurement result to the primary base station. After that, the terminal device sends the measurement result to the main base station in the terminal device information response (InformationResponse). Optionally, when the fourth indication information indicates that the current terminal device has recorded the measurement result corresponding to the radio access technology corresponding to the secondary base station, the primary base station may send the measurement result to the secondary base station after obtaining the measurement result.

It is understandable that, similar to the terminal device sending the measurement result to the primary base station, the terminal device can also send the measurement result to the secondary base station. The difference is that the sending object is the secondary base station, and the interface is the interface between the terminal device and the secondary base station (ie The terminal equipment carries an indication information in the RRC message to the secondary base station, which indicates that the terminal equipment has recorded the measurement result. After receiving the indication information, the secondary base station can send a request to the terminal equipment to report the measurement result, and the terminal equipment receives the request Then send the measurement result to the secondary base station). Optionally, after receiving the measurement result sent by the terminal device, the secondary base station sends the measurement result to the primary base station. For example, the secondary base station may send the measurement result to the primary base station through the Xn interface.

Optionally, when the fourth indication information indicates that the current terminal equipment has recorded the measurement result corresponding to the radio access technology corresponding to the secondary base station, after the primary base station receives the fourth indication information, the primary base station sends an indication information (corresponding The value may be the same as the value of the fourth indication information), indicating that the terminal device has a measurement result corresponding to the radio access technology corresponding to the secondary base station. After the secondary base station receives the instruction, the secondary base station can send a request to the terminal device to report the measurement result, and the terminal device sends the measurement result to the secondary base station after receiving the request.

It should be noted that the base station that receives the measurement result sent by the terminal device may not be the same base station that previously issued the measurement configuration. For example, for logged MDT, after the terminal device receives the measurement configuration, when the terminal device enters the idle state or the inactive state, the terminal device records the corresponding measurement result according to the corresponding measurement configuration, and then the terminal device enters the RRC_CONNECTED state , The terminal device sends the measurement result to the base station. Due to the mobility of the terminal equipment, the base station sending the measurement configuration may not be the same base station as the base station receiving the measurement results.

Operation 210 is optional.

Operation 211: the base station (primary base station or secondary base station) sends a measurement report to the collection entity.

After the primary base station receives the measurement report, where the measurement report carries the measurement result and the RAT information corresponding to the measurement result, the primary base station can report the measurement report to the collecting entity according to the IP address of the collecting entity. In this case, the collecting entity will report the measurement report according to the measurement report. The RAT type corresponding to the measurement result can be known, so that the performance information of the network can be known, and the specific network can be optimized.

It is understandable that, similar to the primary base station sending a measurement report to the collecting entity, the secondary base station may also send a measurement report to the collecting entity. Optionally, after the secondary base station sends the measurement report to the primary base station, the primary base station sends the measurement report to the collection entity.

It should be noted that, when the terminal device does not carry the RAT information corresponding to the measurement result when reporting the measurement result, the base station may also add the RAT information corresponding to the measurement result and send it to the collecting entity.

Operation 211 is optional.

It should be noted that the base station through which the terminal equipment uploads the measurement results and the base station through which the measurement configuration is issued are not necessarily the same base station. In other words, the terminal equipment can send measurement results to other base stations that provide services for it. Therefore, operation 210 and operation 211 is optional.

In practice, there may be scenarios in which multiple sets of measurement configurations need to be sent to the terminal device. For example, two sets of measurement configurations may be sent to the terminal in a dual-connection scenario (for example, one set of MDT measurement configurations for LTE standard, one The set is the MDT measurement configuration of the NR standard); it may also be necessary to perform measurements at different frequency points (for example, one set of low-frequency QoE measurement configuration, one set of high-frequency QoE measurement configuration), that is, there may be permission to terminal equipment Send at least two sets of measurement configuration scenarios.

In order to avoid redundancy, the following embodiments of the present application take the sending of two sets of measurement configurations to the terminal device as an example, and briefly introduce how to negotiate and send the measurement configuration between the access network devices. It is understandable that in a scenario where multiple sets of measurement configurations need to be sent to the terminal device, if the measurement configurations are independently sent between the access network devices, coverage between the measurement configurations may also occur, causing a problem of wasting measurement resources. Based on this, the method of sending a measurement configuration to a terminal device after negotiation between the first access network device and the second access network device mentioned in the 200 method of this application is also applicable to multiple access network devices sending multiple sets to the terminal device. Under the measurement scenario.

Similar to the method 200, the first access network device and the second access network device send two sets of measurement configurations to the terminal device through negotiation. The first access network device has the decision-making power to send the measurement configuration. In the embodiment of the present application, It can be specifically divided into the following optional methods to introduce how to send two sets of measurement configurations to terminal devices through negotiation between access network devices.

In an optional manner, the first access network device sends two sets of measurement configurations to the terminal device, and the first indication information indicates that the second access network device cannot send the measurement configuration to the terminal device.

In an optional manner, the first access network device sends first indication information to the second access network device, instructing the second access network device to send two sets of measurement configurations to the terminal device. Optionally, the first indication information The relevant information of the two sets of measurement configurations (for example, the management-based MDT measurement configuration of the LTE standard, or the high-frequency QoE measurement configuration) can be carried.

In an optional manner, the first access network device sends first indication information to the second access network device, instructing the second access network device to send a set of measurement configuration to the terminal device, that is, the first access network device Both the network device and the second access network device only send one set of measurement configurations to the terminal device.

In another embodiment of the present application, the first access network device negotiates with multiple second access network devices to send one or more sets of measurement configurations to the terminal device, where the first access network device has a measurement configuration to send In the embodiment of this application, the negotiation between the primary base station and two secondary base stations (denoted as the first secondary base station and the second secondary base station respectively for the convenience of description) is taken as an example in the embodiment of this application, and is specifically divided into the following options Introduce how the primary base station and multiple secondary base stations negotiate to send a set of measurement configurations to the terminal equipment.

In an optional manner, the primary base station sends the measurement configuration to the terminal device, the seventh indication information indicates that the first secondary base station cannot send the measurement configuration to the terminal device, and the eighth indication information indicates that the second secondary base station cannot send the measurement configuration to the terminal device. Configuration.

In an optional manner, the primary base station indicates through the seventh indication information that the first secondary base station can send the measurement configuration to the terminal device, and through the eighth indication information indicates that the second secondary base station cannot send the measurement configuration to the terminal device.

In an optional manner, the primary base station indicates through the seventh indication information that the first secondary base station cannot send the measurement configuration to the terminal device, and through the eighth indication information indicates that the second secondary base station can send the measurement configuration to the terminal device.

In an optional manner, the first secondary base station sends the fourth request information to the primary base station to request the measurement configuration to be sent to the terminal device, the primary base station agrees with the fourth request information, and the primary base station indicates through the eighth indication information that the second secondary base station cannot send the measurement configuration to the terminal The device sends the measurement configuration.

In an optional manner, the second secondary base station sends the fifth request information to the primary base station to request the measurement configuration to be sent to the terminal device, the primary base station agrees with the fifth request information, and the primary base station indicates through the seventh indication information that the first secondary base station cannot send the measurement configuration to the terminal. The device sends the measurement configuration. It is understandable that the first access network device and multiple second access network devices can also send multiple sets of measurement configurations to the terminal device after negotiation. The negotiation mechanism is similar to the foregoing embodiment, and only one set of measurement configurations is sent after negotiation. The difference in configuration is that the first access network device can instruct multiple second access network devices to send the measurement configuration to the terminal device.

In the scenario where multiple sets of measurement configurations need to be sent to the terminal device, the terminal device needs to allocate memory for the measurement results. Due to the limitation of the limited memory resources of the terminal device, this application proposes a memory allocation method for the measurement results corresponding to multiple sets of measurement configurations. A flexible memory storage method, specifically, the memory can be independent or shared.

Taking the terminal device receiving two sets of measurement configurations as an example, FIG. 3 is a schematic flowchart of a communication method 300 provided in an embodiment of the present application. The technical solutions of the embodiments of the present application will be described in detail below with reference to FIG. 3 in the embodiments of the present application. Exemplarily, the communication method corresponding to FIG. 3 includes:

Operation 301: The terminal device obtains at least two sets of measurement configurations.

Take the terminal device to obtain two sets of measurement configurations as an example. For example, the two sets of measurement configurations can be a set of high-frequency QoE measurement configurations and a set of low-frequency QoE measurement configurations, or both sets of measurement configurations can be logged MDT measurements. . Optionally, the two sets of measurement configurations may be sent by the primary base station, or the secondary base station may send two sets of measurement configurations, or the primary base station sends a set of measurement configurations and the secondary base station sends a set of measurement configurations. Optionally, the measurement configuration can be received through an RRC message.

Operation 302: the primary base station or the secondary base station sends sixth indication information to the terminal device.

Among them, the sixth indication information is used to indicate the memory allocation mode of the two sets of measurement results, which may be independent memory storage or shared memory storage. It is understandable that the primary base station may send the sixth indication information to the terminal device, or the secondary base station may send the sixth indication information to the terminal device. Optionally, the sixth indication information may be sent to the terminal device through the Uu interface.

Operation 302 is optional.

It should be noted that there is no strict sequence relationship between operations 301 and 302, and the embodiment of the present application is not limited.

Operation 303: The terminal device determines the memory allocation mode.

After the terminal device receives the two sets of measurement configurations, the terminal device needs to determine the memory allocation mode of the two sets of measurement results corresponding to the two sets of measurement configurations. In the embodiment of this application, it can be specifically divided into the following optional methods to introduce the memory allocation methods of the two sets of measurement results of the terminal device:

An optional method: the memory of the two sets of measurement results are independent, that is, the two sets of measurement results have their own independent memory. For example, the terminal device allocates 64K and 64K of memory for the two sets of measurement results. This application Not limited. Optionally, in this allocation mode, when the memory corresponding to the logged MDT corresponding to a certain radio access technology is full, only the measurement and measurement result recording corresponding to the logged MDT of the radio access technology is stopped. The terminal device may discard the saved measurement results of the logged MDT record of the wireless access technology after a certain time (for example, 48 hours). That is to say, after the memory corresponding to the logged MDT corresponding to a certain wireless access technology is full, it does not affect the measurement and measurement result recording of the logged MDT corresponding to another wireless access technology.

Optionally, when the terminal device determines that the memory of the two sets of measurement results are independent, the memory allocation ratio can be further determined. For example, the allocation ratio is 3:1, and the total memory reserved by the terminal device for the measurement result is 128K, and the terminal device allocates 96K and 32K memory for the two sets of measurement results, which is not limited by this application. It should be noted that this embodiment of the application does not limit how the terminal device selects the memory allocation ratio. The sixth indication message sent by the base station in operation 302 may carry the memory allocation ratio, or the base station may newly define a message to send the memory allocation ratio to the terminal device, or the terminal device may determine the memory allocation ratio internally. limited. An optional method: the memory allocation method of the two sets of measurement results is shared, that is, the two sets of measurement results share the memory. This will increase the maximum value of the memory that a single measurement result can store. For example, if the total shared memory of two sets of measurement results is 128K, the maximum memory that can be stored in a single measurement result is 128K, which will be larger than 64K in the case of independent memory allocation, which provides flexible memory allocation options and maximizes the use of memory . Optionally, in this allocation mode, when the memory for storing the logged MDT measurement record of the terminal device is full, the logged MDT measurement and recording corresponding to the two wireless access technologies is stopped. The terminal device can discard the saved measurement results of the logged MDT record after a certain period of time (for example, 48 hours). That is to say, after the memory corresponding to the logged MDT is full, the measurement and measurement result recording of the logged MDT corresponding to the two wireless access technologies are stopped.

In an optional manner, the terminal device can further determine the priority of the measurement result, that is, the terminal device preferentially stores the measurement result with high priority, or for the measurement result of the same type of measurement, the terminal device can use the measurement result with high priority Overwrite low-priority measurement results. It is understandable that the priority of the measurement result can be specified by the access network device or independently determined by the terminal device. It should be noted that the priority storage or overwriting here may refer to the behavior when the memory corresponding to the logged MDT of the terminal device is full.

It should be noted that this embodiment of the present application does not limit how the terminal device selects the memory allocation mode. The terminal device may determine the memory allocation method according to the sixth instruction information sent by the base station in operation 302, that is, the sixth instruction information indicates which memory allocation method is used. It is also possible that the protocol specifies which memory allocation method is used, or the internal implementation of the terminal device may completely determine the memory allocation method, which is not limited by this application.

In another embodiment of the present application, when the terminal device receives multiple measurement configurations, for example, the terminal device receives two sets of measurement configurations respectively sent by the primary base station and the secondary base station. The terminal device decides whether to cover the measurement configuration, that is, the terminal device decides to keep several measurement configurations. such as. When the terminal device has the ability to retain two sets of measurement configurations, when the terminal device receives the two sets of configurations, there is no need to cover the measurement configuration, and the terminal can retain both sets of measurement configurations at the same time. When the terminal device only has the ability to maintain one set of measurement configurations, when the terminal device receives two sets of measurement configurations, the terminal performs measurement configuration coverage (for example, the latest measurement configuration covers the measurement configuration received before).

It is understandable that the embodiment shown in FIG. 3 is exemplified by two base stations and the terminal receives two sets of measurement configurations. The method described in the embodiment in FIG. 3 can also be applied to two base stations and the terminal receives multiple sets of measurement. Configuration, and further, applicable to scenarios where multiple base stations and multiple sets of measurement configurations are received by the terminal, the processing method for the above multiple base stations and multiple sets of measurement configurations is similar to the embodiment shown in FIG. 3, The access network equipment determines the memory allocation method for the measurement results corresponding to multiple measurement configurations, or the terminal device independently determines the memory allocation method. Optionally, the memory allocation for the measurement results corresponding to multiple measurement configurations can be independent or Is shared. Optionally, the access network device or the terminal device may indicate the priority of multiple sets of measurement results.

For immediate MDT, the measurement in immediate MDT may be performed by different entities of the base station. For example, for the uplink interference power measurement in the immediate MDT, the measurement is performed by the DU, and for the power headroom measurement of the terminal device, the terminal device reports to the DU. For the signal quality measured by the terminal device, the terminal device reports the measurement result to the CU. For the throughput or data volume measurement of terminal equipment, the measurement may be performed by CU-UP. For operators, they may want to know the measurement results performed or obtained by different entities of the same terminal device. If these measurement results are first uniformly sent to a certain entity of the base station, it will cause a large number of measurement result interactions between different entities (such as F1/E1 ports), which will bring a relatively large interaction load. So one method is that each entity of the base station sends the corresponding results directly to the tracking collection entity TCE. However, a method is needed for TCE to know that the measurement results from various entities are about the same terminal device. In another embodiment of the present application, when each entity sends a measurement result to the TCE, it carries identification information so that the TCE knows whether the measurement result received from each entity is about the same terminal device.

FIG. 4 is a schematic flowchart of a communication method 400 provided by an embodiment of the present application. The following will specifically describe how the TCE learns that the measurement results received from each entity of a single base station are about the same terminal device with reference to FIG. 4 in the embodiment of the present application. Exemplarily, the communication method corresponding to FIG. 4 includes:

Operation 410: When each entity of the base station collects the corresponding MDT measurement result, it sends the corresponding measurement result to the tracking collection entity TCE, and carries identification information about the corresponding terminal device.

It should be noted that before this step, each entity of the base station (such as CU-CP, CU-UP, DU) will receive their corresponding measurement configuration. For example, when CU-CP receives the corresponding MDT measurement configuration from the core network or network management, CU-CP will send the measurement configuration related to other entities to other entities (for example, CU-CP sends to CU-UP through E1 interface, CU- The CP is sent to the DU through the F1 interface).

Optionally, the identification information of the terminal device may be a cell radio temporary identification C-RNTI allocated by the base station to the terminal device.

Optionally, when the CU-CP reports the measurement result, it carries at least one of the following: the terminal device's F1-C port identification information on the CU-CP side (such as gNB-CU UE F1AP ID), and the terminal device is in the DU The identification information of the F1-C port on the side (such as gNB-DU UE F1AP ID), and the identification information of the E1 port on the CU-CP side allocated by CU-CP for the terminal device (such as gNB-CU-CP UE E1AP ID) CU-UP is the identification information of the E1 port on the CU-UP side allocated by the terminal device (such as gNB-CU-UP UE E1AP ID), and the C-RNTI corresponding to the terminal device.

Optionally, when the CU-UP reports the measurement result, it carries at least one of the following: CU-CP assigns the terminal device’s E1 port identification information on the CU-CP side, and CU-UP assigns the terminal device’s The identification information of the E1 port on the CU-UP side, the identification information of the F1-U port on the CU-UP side allocated by the CU-UP for the terminal device (such as the transport layer address and the GTP tunnel on the CU-UP side in the F1-U port Port identification), the identification information of the F1-U port on the DU side allocated by the DU for the terminal device (for example, the transport layer address on the DU side in the F1-U port and the GTP tunnel port identification), and the C-RNTI corresponding to the terminal device.

Optionally, when the DU reports the measurement result, it carries at least one of the following: CU-CP allocates F1-C port identification information on the CU-CP side for the terminal device, and DU allocates the terminal device on the DU side The identification information of the F1-C port, CU-UP is the identification information of the F1-U port on the CU-UP side allocated by the terminal device, and the DU is the identification information of the F1-U port on the DU side allocated by the terminal device , The C-RNTI corresponding to the terminal device.

Optionally, an entity (such as CU-CP) allocates an identifier (the existing RAN UE ID in the protocol can be used), and sends the identifier to other entities (such as CU-CP sends the identifier to CU- UP and DU). In this way, each entity carries the identifier when reporting the measurement result of the terminal device. Further, since more entities may be connected to another entity (for example, multiple DUs are connected to a CU), each entity may also interact with the identification of other entities (for example, CU-CP sends the identification of DU to CU- UP). In this way, when certain entities report the measurement results of the terminal device, they also carry the identity of the entity (for example, CU-UP also carries the identity of the DU when reporting. CU-UP, CU-CP, and DU can also report their respective Logo). Further, CU-UP, CU-CP, and DU will carry a trace ID when receiving the corresponding measurement configuration. Each entity may carry the tracking identifier when reporting the measurement result of the terminal device.

Optionally, for some measurements, the measurement results of multiple entities need to be integrated to obtain the final result. For example, for delay measurement, each entity periodically measures the delay in the corresponding entity (such as the delay on the CU-UP side, the delay on the DU side, etc.) in each entity. In order to obtain the delay of the entire wireless side, the measurement results in each entity need to be integrated. In addition to carrying the identification information of the above terminal equipment, each entity can also carry a measurement sequence number, which represents the sequence number of the measurement period corresponding to the measurement result. In this way, the tracking collection entity TCE can obtain the corresponding measurement period of the entire wireless side in the same measurement period according to the measurement sequence number. Time delay (for example, the sum of the measurement results of each entity in the same measurement sequence number is regarded as the time delay on the wireless side).

Optionally, in addition to the identification information of the above terminal device, each entity also carries time information, which indicates that each entity receives or sends time information corresponding to these measurement results.

Optionally, the above steps may be for immediate MDT based on management. Optionally, the above steps may also be directed to immediate MDT based on signaling. Optionally, management-based immediate MDT and signaling-based immediate use different methods. Management-based immediate MDT uses the above methods. For signaling-based immediate MDT, CU-CP can receive data from the core network. The trace ID is sent to CU-UP and DU. The CU-CP, CU-UP and DU carry the tracking identifier when sending the measurement result to the TCE, so that the TCE can associate the measurement result of a certain terminal device in the CU-CP/CU-UP/DU according to the tracking identifier.

Operation 420: The tracking collection entity TCE associates the MDT measurement results collected from various entities of the base station to the same terminal device according to the identification information of the terminal device.

The tracking collection entity TCE carries the identification information of the terminal device when collecting and reporting the measurement results according to the various entities of the base station, and can associate the measurement results with the same terminal device.

For example, the measurement results reported by each entity are associated with the same terminal device according to the C-RNTI.

For example, according to the identification of the F1-C port on the CU-CP side and the identification of the F1-C port on the DU side, the measurement results sent by the CU-CP and the DU can be associated with the same terminal device. According to the identification of the F1-U interface on the CU-UP side and the identification of the F1-U interface on the DU side, the measurement results sent by the CU-UP and the DU can be associated with the same terminal device. According to the identification of the E1 port on the CU-CP side and the identification of the E1 port on the CU-UP side, the measurement results sent by the CU-CP and CU-UP can be associated with the same terminal device.

It should be noted that the above method for the TCE to learn whether the measurement results received from each entity are about the same terminal device can also be extended between other entities, such as between the primary base station and the secondary base station.

FIG. 5 is a schematic flowchart of a communication method 500 provided by an embodiment of the present application. The following will specifically describe how the TCE learns that the measurement results received from entities of multiple base stations are about the same terminal device with reference to FIG. 5 in the embodiment of the present application. Exemplarily, the communication method corresponding to FIG. 4 includes:

Operation 510: When the two base stations collect the corresponding MDT measurement results, they send the corresponding measurement results to the tracking collection entity TCE, and carry identification information about the corresponding terminal devices.

It should be noted that before this step, the two base stations will receive their corresponding measurement configurations. For example, the primary base station will send the measurement configuration to the secondary base station according to the measurement configuration received from the core network or network management. Or the primary base station and the secondary base station respectively receive the measurement configuration from the network management.

Optionally, the identification information of the terminal device may be the cell radio temporary identification C-RNTI allocated by each base station to the terminal. For example, when the primary base station sends the measurement result of the terminal, it carries the C-RNTI respectively allocated by the primary base station and the secondary base station to the terminal equipment. -RNTI, when the secondary base station sends the measurement result of the terminal, it carries the C-RNTI allocated by the primary base station and the secondary base station to the terminal device. Before this step, the primary base station and the secondary base station will exchange the C-RNTI allocated to the terminal device.

Optionally, when the main base station reports the measurement results, it carries at least one of the following: the terminal device's Xn or X2 port identification information on the main base station side (such as MN UE XnAP ID or MN UE X2AP ID on the control plane, or/ And the MN side transport layer address of the user plane and the GTP tunnel port identifier), the Xn or X2 port identification information of the terminal device on the secondary base station side (such as SN UE XnAP ID or SN UE X2AP ID, or/and the SN side of the user plane Transport layer address and GTP tunnel port identifier), the terminal equipment is in the C-RNTI corresponding to the primary base station and the secondary base station.

Optionally, when the secondary base station reports the measurement result, it carries at least one of the following: the terminal device's Xn or X2 port identification information on the primary base station side (such as MN UE XnAP ID or MN UE X2AP ID on the control plane, or/ And the MN side transport layer address of the user plane and the GTP tunnel port identifier), the Xn or X2 port identification information of the terminal device on the secondary base station side (such as SN UE XnAP ID or SN UE X2AP ID, or/and the SN side of the user plane Transport layer address and GTP tunnel port identifier), the terminal equipment is in the C-RNTI corresponding to the primary base station and the secondary base station.

Optionally, a certain base station (for example, a primary base station allocates an identifier), and sends the identifier to other base stations. In this way, the base station carries the identifier when reporting the measurement result of the terminal device.

Optionally, in addition to carrying the identification information of the above terminal equipment, each base station also carries time information, which indicates the time information corresponding to each base station receiving or sending these measurement results.

Optionally, the above steps may be for immediate MDT based on management. Optionally, the above steps may also be directed to immediate MDT based on signaling. Optionally, management-based immediate MDT and signaling-based immediate use different methods. Management-based immediate MDT uses the above methods. For signaling-based immediate MDT, the master base station can take the information received from the core network The trace ID is sent to the secondary base station. When the primary base station and the secondary base station send the measurement results to the TCE, the tracking identifier is carried, so that the TCE can associate the measurement results of a certain terminal device at the primary base station and the secondary base station according to the tracking identifier.

It should be noted that, optionally, when a base station has a CU/DU architecture, the CU of the base station may also send the above identification information of the terminal device to other entities of the base station (for example, the CU-CP sends the terminal The identification information of the device is sent to CU-UP and DU).

Operation 520: the tracking collection entity TCE associates the MDT measurement results collected from each base station to the same terminal device according to the identification information of the terminal device.

The tracking collection entity TCE carries the identification information of the terminal device when collecting and reporting the measurement result of each base station, and can associate the measurement result to the same terminal device.
