Description

Method and device for sending self-organizing network report

technical field

The embodiments of the present application relate to the field of wireless communication, and in particular to a method and device for sending an ad hoc network report.

Background technique

In the fifth generation (5th Generation, 5G) mobile communication system, the user equipment (user equipment, UE) will send a self-organizing network (self-organizing network, SON) report to the base station, so that the base station can optimize the parameters of the wireless network . Specifically, the SON report may be a radio link failure report, a connection establishment failure (connection establishment failure, CEF) report, a handover success report, or a random access report. The CEF report may include connection establishment failure information and/or connection recovery failure information. The following describes the CEF report as a specific example of the SON report.

For a UE in a non-connected state, when the UE needs to transmit information with the base station, the UE will initiate a connection establishment request to the base station to establish a radio resource control (radio resource control, RRC) connection with the base station, for example , the UE in the idle state will initiate an RRC establishment request, and the inactive state (inactive state) UE will initiate an RRC resume (resume) request. Due to various reasons, the UE may not be able to successfully establish an RRC connection with the base station, thereby generating a CEF.

When the UE detects CEF, it can generate a CEF report and store the CEF report in the CEF report variable VarConnEstFailReport. The CEF report may include the information of the cell where the CEF is detected; the cell information may include the identification information of the cell, or include the identification information of the cell and the quality information of the cell. The CEF report may also indicate at least one of location information, measurement results of neighboring cells, number of connection failures in the cell, and time interval information between detecting CEF and sending CEF report. After the UE establishes the RRC connection with the base station, it can send the CEF report stored in the CEFVarConnEstFailReport to the base station.

In different protocol versions of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP), the storage and sending capabilities of the CEF report supported by the UE and the base station may be different. For example, in the version 16 (release 16, R16) protocol, the UE only supports the storage and sending of one CEF report, while in the version 17 (release 17, R17) protocol, the UE can use the R17 CEF report list information element connEstFailReportList -r17 Send up to 4 CEF reports at the same time.

When the processing capabilities of the UE and the base station may be inconsistent with each other, how the UE sends the CEF report so that the base station can parse the CEF report sent by the UE in a correct format is a technical problem to be solved in this application.

Wherein, the radio access network 100 may include at least one radio access network device (such as 110a and 110b in FIG. 1 ), and may also include at least one terminal (such as 120a-120j in FIG. 1 ). The terminal is connected to the wireless access network device in a wireless manner, and the wireless access network device is connected to the core network in a wireless or wired manner. The core network equipment and the wireless access network equipment can be independent and different physical equipment, or the functions of the core network equipment and the logical functions of the wireless access network equipment can be integrated on the same physical equipment, or it can be a physical equipment It integrates some functions of core network equipment and some functions of wireless access network equipment. Terminals and wireless access network devices may be connected to each other in a wired or wireless manner. FIG. 1 is only a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG. 1 .

The radio access network device is the access device for the terminal to access the communication system through wireless means. The wireless access network equipment may be a base station (base station), an evolved base station (evolved NodeB, eNodeB), a transmission reception point (transmission reception point, TRP), or a next-generation mobile communication system in the fifth generation (5th generation, 5G) Base station (next generation NodeB, gNB), the next generation base station in the sixth generation (6th generation, 6G) mobile communication system, the base station in the future mobile communication system or the access node in the WiFi system, etc.; it can also complete the base station part The functional module or unit, for example, may be a centralized unit (central unit, CU) or a distributed unit (distributed unit, DU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the base station The functions of the radio link control layer and the medium access control (medium access control, MAC) layer can also complete the functions of part or all of the physical layer. For the specific description of the above-mentioned protocol layers, you can refer to the third generation partnership project (3rdgeneration partnership project, 3GPP) related technical specifications. The radio access network device may be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), or a relay node or a donor node. The embodiment of the present application does not limit the specific technology and specific equipment form adopted by the radio access network equipment. For ease of description, a base station is used as an example of a radio access network device for description below.

The terminal is a device with wireless transceiver function, which can send signals to the base station or receive signals from the base station. A terminal may also be called terminal equipment, UE, mobile station, mobile terminal, and the like. Terminals can be widely used in various scenarios, for example, device-to-device (device-to-device, D2D), vehicle-to-everything (V2X) communication, machine-type communication (machine-type communication, MTC), Internet of Things ( internet of things, IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. Terminals can be mobile phones, tablet computers, computers with wireless transceiver functions, wearable devices, vehicles, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiment of the present application does not limit the specific technology and specific device form adopted by the terminal.

Base stations and terminals can be fixed or mobile. Base stations and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed on aircraft, balloons and artificial satellites. The embodiments of the present application do not limit the application scenarios of the base station and the terminal.

The roles of the base station and the terminal can be relative. For example, the helicopter or UAV 120i in FIG. base station; however, for base station 110a, 120i is a terminal, that is, communication between 110a and 120i is performed through a wireless air interface protocol. Of course, communication between 110a and 120i may also be performed through an interface protocol between base stations. In this case, compared to 110a, 120i is also a base station. Therefore, both the base station and the terminal can be collectively referred to as a communication device, 110a and 110b in FIG. 1 can be referred to as a communication device with a base station function, and 120a-120j in FIG. 1 can be referred to as a communication device with a terminal function.

The communication between the base station and the terminal, between the base station and the base station, and between the terminal and the terminal can be carried out through the licensed spectrum, the communication can also be carried out through the unlicensed spectrum, and the communication can also be carried out through the licensed spectrum and the unlicensed spectrum at the same time; Communications may be performed on frequency spectrums below megahertz (gigahertz, GHz), or communications may be performed on frequency spectrums above 6 GHz, or communications may be performed using both frequency spectrums below 6 GHz and frequency spectrums above 6 GHz. The embodiments of the present application do not limit the frequency spectrum resources used for wireless communication.

In the embodiments of the present application, the functions of the base station may also be performed by modules (such as chips) in the base station, or may be performed by a control subsystem including the functions of the base station. The control subsystem including base station functions here may be the control center in the above application scenarios such as smart grid, industrial control, intelligent transportation, and smart city. The functions of the terminal may also be performed by a module (such as a chip or a modem) in the terminal, or may be performed by a device including the terminal function.

In this application, the base station sends a downlink signal or downlink information to the terminal, and the downlink information is carried on the downlink channel; the terminal sends an uplink signal or uplink information to the base station, and the uplink information is carried on the uplink channel. In order to communicate with the base station, the terminal needs to establish a wireless connection with the cell controlled by the base station. A cell with which a terminal has established a wireless connection is called a serving cell of the terminal. When the terminal communicates with the serving cell, it will also be interfered by signals from neighboring cells.

For a UE supporting the 3GPP R16 protocol (referred to as R16 UE), only a single CEF report format is supported but not multiple CEF report formats. The so-called single CEF report format means that the UE can send a CEF report to the base station through the first RRC information element. Specifically, as described in 3GPP technical specification (technical specification, TS) 38.331V16.7.0, the UE can send a CEF report to the base station through the connEstFailReport-r16 information element. Correspondingly, for a base station supporting the 3GPP R16 protocol (referred to as a R16 base station), it only supports a single CEF report format and does not support multiple CEF report formats, that is, a CEF report from the UE can be received through the connEstFailReport-r16 information element. In the following, R16 UEs are taken as specific examples of UEs that only support single CEF report format but not multiple CEF report formats, and R16 base stations are taken as specific examples of base stations that only support single CEF report format but not multiple CEF report formats.

For a UE supporting the 3GPP R17 protocol (referred to as a R17 UE), it can simultaneously support a single CEF report format and multiple CEF report formats. The so-called multi-CEF report format means that the UE can simultaneously send at most M CEF reports to the base station through the second RRC information element, M is an integer greater than 1, and M is the maximum number of CEF reports supported by the multi-CEF report format. The above-mentioned second RRC information element is different from the first RRC information element. For example, the UE can simultaneously send up to four CEF reports to the base station through the connEstFailReportList-r17 information element, that is, M can be equal to four. Correspondingly, for a base station supporting the 3GPP R17 protocol (referred to as a R17 base station), it can simultaneously support a single CEF report format and multiple CEF report formats. In the following, an R17 UE is taken as a specific example of a UE supporting multiple CEF reporting formats, and an R17 base station is taken as a specific example of a base station supporting multiple CEF reporting formats. It can be understood that a UE and a base station supporting multiple CEF reporting formats may also support a single CEF reporting format.

The R17 UE may send a capability indication to the base station, indicating that the UE supports multiple CEF report formats. For an R17 base station, the capability indication can be used to know that the UE supports multiple CEF report formats. However, for the R17 UE, it is impossible to know whether the current base station supports the R16 protocol or the R17 protocol. If an R17 UE sends a CEF report to an R16 base station in a multi-CEF report format, the base station cannot parse the CEF report in the correct format. If the R17 UE always only sends a CEF report to the base station in a single CEF report format, only one CEF report can be sent at a time, and the multi-CEF report format of R17 cannot be used normally.

When the processing capabilities of the UE and the base station may be inconsistent with the CEF report, how to send the CEF report so that the base station can analyze the CEF report sent by the UE in the correct format. The embodiment of this application proposes the CEF report shown in Figure 2 The method M200 for sending a CEF report, the method M300 for sending a CEF report as shown in FIG. 3 , and the method M400 for sending a CEF report as shown in FIG. 4 . In the embodiment of the present application, the CEF report may be replaced by other SON reports, for example, it may be a radio link failure report, a handover success report or a random access report. Hereinafter, the embodiment of the present application will be described in detail by taking the CEF report as a specific example of the SON report.

It can be understood that R16 is only a specific example of a protocol version that does not support multiple CEF report formats, and R17 is only a specific example of a protocol version that supports multiple CEF report formats. This application does not apply to the protocol versions applicable to the embodiments. Do limited.

In the method M200, the UE determines the format for sending the CEF report according to the number of CEF reports to be sent, so that both the R16 base station and the R17 base station can parse the CEF report sent by the R17 UE according to the correct format .

S210, the base station sends a CEF report request to the UE, where the CEF report request instructs the UE to send a CEF report. Correspondingly, the UE receives the CEF report request from the base station.

The CEF report request sent by the R16 base station and the R17 base station are the same, and the R17 UE cannot distinguish whether it is the CEF report request sent by the R16 base station or the CEF report request sent by the R17 base station. In this application, the CEF report request may be carried in the UE information request message of the RRC signaling.

S220, the UE determines a format for sending a CEF report according to the number of CEF reports to be sent, and the format may be a single CEF report format, or a single CEF report format and a multi-CEF report format.

S230, the UE sends a CEF report to the base station according to the determined format.

The UE may use a single CEF report format to send a CEF report to the base station; or, the UE uses a single CEF report format and multiple CEF report formats to send a CEF report.

Specifically, when the UE has only one CEF report to be sent, the UE sends the CEF report to the base station in a single CEF report format. The CEF report to be sent may be stored in a variable of the UE's single CEF report format, or may be stored in a variable of the UE's multi-CEF report format; or the CEF report to be sent may be stored in a single CEF report In the variables of the format and the variables of the multi-CEF report format, for example, the content of the CEF report in the variables of the single-CEF report format and the variables of the multi-CEF report format is the same, that is, when the UE detects CEF, the variables in the single-CEF report format and the variables of the multi-CEF report format are respectively The CEF report is recorded in the variable of the multi-CEF report format. At this time, although the UE stores a CEF report in the variable of the single-CEF report format and the variable of the multi-CEF report format, but due to the variable of the single-CEF report format and the multi-CEF report The contents of the two CEF reports stored in the format variable are the same, and the UE may consider that it has only one CEF report to send. The variable of the single CEF report format may be VarConnEstFailReport-r16 defined in 3GPP TS38.331 V16.7.0. A variable for the multi-CEF report format may be VarConnEstFailReportList-r17. In the embodiment of the present application, how many CEF reports the UE has to send can be judged by how many CEF reports are cached in the cache of the UE.

When the UE has N CEF reports to be sent, and N is an integer greater than 1 and less than or equal to M+1, the UE uses the single CEF report format to send the first CEF report in the N CEF reports, and uses the multi-CEF report format to send The remaining N-1 CEF reports in the N CEF reports. In this application, the first CEF report may be the first CEF report generated among the N CEF reports to be sent, or the CEF report generated last among the N CEF reports to be sent, or the CEF report to be sent Any one of the N CEF reports.

When the UE has N CEF reports to be sent, and N is an integer greater than M+1, the UE uses the single CEF report format to send the first CEF report among the N CEF reports, and uses the multi-CEF report format to send the N CEF reports M CEF reports other than the first CEF report in the report. Further, the UE may send a CEF report buffer indication to the base station, indicating to the base station that the UE still has a CEF report to be sent.

The above-mentioned first CEF report may be stored in a variable of the UE's single CEF report format, or may be stored in a variable of the UE's multi-CEF report format. When the first CEF report is stored in a variable of the single CEF report format of the UE, the remaining CEF reports of the above N CEF reports may be stored in variables of the multi-CEF report format. Optionally, the above N CEF reports to be sent may all be stored in variables in the multi-CEF report format.

In the above implementation manner, the CEF report in the single CEF report format and the CEF report in the multi-CEF report format are different CEF reports. In another implementation manner, the CEF report in the single CEF report format may also be a CEF report in the multi-CEF report format. Correspondingly, the above N CEF reports to be sent may all be stored in variables of the multi-CEF report format of the UE. In yet another implementation manner, the CEF report in the single-CEF report format may also be a CEF report with the same content stored in the variables of the single-CEF report format and the variables of the multi-CEF report format respectively.

Specifically, when the UE has N CEF reports to be sent, and N is an integer greater than 1 and less than or equal to M, the UE uses the single CEF report format to send the first CEF report in the N CEF reports, and uses multiple CEF reports at the same time format to send the N CEF reports. When the UE has N CEF reports to be sent, and N is an integer greater than M, the UE uses the single CEF report format to send the first CEF report in the N CEF reports, and uses the multi-CEF report format to send the N CEF reports. M CEF reports including the first CEF report. Further, the UE may send a CEF report buffer indication to the base station, indicating to the base station that the UE still has a CEF report to be sent.

Through the above method M200, for the R16 base station, the CEF report sent in the single CEF report format can be parsed; for the R17 base station, the CEF report sent in the single CEF report format and the multi-CEF report sent in the multi-CEF report format can be parsed at the same time. A CEF report.

In method M300, the base station sends a CEF report format indication to the UE, indicating which CEF report format the UE adopts to send the CEF report, so that the UE can send the CEF report to the base station in a manner consistent with the understanding of the base station, so that the base station can Parse the CEF report sent by the UE according to the correct format.

S310, the base station sends a CEF report request and a CEF report format indication to the UE, the CEF report request instructs the UE to send a CEF report, the CEF report format indication indicates a format for the UE to send a CEF report, and the format of the CEF report may be a single CEF report format and/or or multiple CEF report formats. Correspondingly, the UE receives the CEF report request and the CEF report format indication from the base station.

The CEF report format indication may be carried in RRC signaling. The CEF report format indication can be an information element in the CEF report request (that is, the CEF report request information element includes the CEF report format indication information element), or it can be an information element in the UE information request message that is different from the CEF report request, or it can be Carried in a different message than the one carrying the CEF report request.

S320, the UE determines a format for sending a CEF report according to the CEF report format indication.

S330, the UE sends a CEF report to the base station according to the determined format. Correspondingly, the base station receives the CEF report from the UE, and the base station parses the CEF report according to the format indicated by the CEF report format indication.

Specifically, the CEF report format indication may indicate that the format of the CEF report is a multi-CEF report format. When the UE has N CEF reports to be sent, and N is a positive integer less than or equal to M, the UE sends the above N CEF reports to the base station in a multi-CEF report format. When the UE has N CEF reports to be sent, and N is an integer greater than M, the UE uses the single CEF report format to send the first CEF report among the above N CEF reports, and uses the multi-CEF report format to send the above N CEF reports to the base station M CEF reports other than the first CEF report in the CEF report. Further, when N is greater than M+1, the UE may also send a CEF report buffer indication to the base station, indicating to the base station that the UE still has a CEF report to be sent.

Optionally, before the base station sends the CEF report request and the CEF report format indication to the UE, the base station can know that the UE can support multiple CEF report formats by receiving the CEF report capability indication sent by the UE. It can also be understood that the UE supports the R17 protocol UE.

For the R17 base station, the base station can send a CEF report format indication to the R17 UE, indicating that the format of the CEF report is a multi-CEF report format, so that the R17 UE can use the multi-CEF report format to send a CEF report to the R17 base station. For the scenario where the CEF report format instruction is not received, it means that the base station does not support multiple CEF report formats, and the R17 UE can use the single CEF report format to send a CEF report to the base station. The above method can enable both the base station of R16 and the base station of R17 to parse the CEF report sent by the UE of R17 according to the correct format.

The CEF report format indication may instruct the UE to preferentially use a single CEF report format to send a CEF report to the base station.

For example, the CEF report format may instruct the UE: when the UE has only one CEF report to send, the UE uses a single CEF report format to send the CEF report, thereby reducing the signaling overhead of sending the CEF report. When the UE has N CEF reports to be sent, and N is an integer greater than 1, the UE uses the single CEF report format to send the first CEF report among the N CEF reports, and can send a CEF report buffer indication to the base station, indicating to the base station The UE still has a CEF report to send. Or, when the UE has N CEF reports to be sent, and N is an integer greater than 1 and less than or equal to M+1, the UE uses the single CEF report format to send the first CEF report among the N CEF reports, and uses multiple CEF The report format sends the remaining N-1 CEF reports among the N CEF reports. Or, when the UE has N CEF reports to be sent, and N is an integer greater than M+1, the UE uses the single CEF report format to send the first CEF report among the N CEF reports, and uses the multi-CEF report format to send the N M CEF reports except the first CEF report in the CEF reports; further, the UE may send a CEF report buffer indication to the base station, indicating to the base station that the UE still has CEF reports to be sent.

For another example, the CEF report format may instruct the UE: when the UE has only one CEF report to send, the UE uses a single CEF report format to send the CEF report. Or, when the UE has N CEF reports to be sent, and N is an integer greater than 1 and less than or equal to M, the UE sends the N CEF reports in a multi-CEF report format. Or, when the UE has N CEF reports to be sent, and N is an integer greater than M, the UE uses the single CEF report format to send the first CEF report in the N CEF reports, and uses the multi-CEF report format to send the N M CEF reports in the CEF report, or the UE only uses the multi-CEF report format to send M CEF reports in the N CEF reports; further, the UE can send a CEF report buffer indication to the base station, indicating to the base station that the UE has yet to Sent CEF report.

For the manner in which the above N CEF reports to be sent are stored in the UE, reference may be made to related descriptions in method M200.

The base station parses the CEF report according to the format indicated by the CEF report format indication, which may specifically include the following situations.

When the CEF report format indication indicates that the format of the CEF report is the multi-CEF report format, the base station uses the multi-CEF report format to receive the CEF report from the UE. Optionally, the base station may also try to receive the CEF report from the UE in a single CEF report format. If the base station receives the CEF report through the single CEF report format, it indicates that the UE has sent M+1 CEF reports in total. Further, the base station may also try to receive a CEF report buffer indication from the UE. If the base station receives the CEF report buffer indication, it indicates that the UE still has a CEF report to be sent.

When the CEF report format indication indicates that the UE preferentially uses the single CEF report format to send the CEF report to the base station, the base station uses the single CEF report format to receive the CEF report from the UE. Further, the base station may also try to receive a CEF report buffer indication from the UE. If the base station receives the CEF report buffer indication, it indicates that the UE still has a CEF report to be sent. Optionally, the base station may also try to receive the CEF report from the UE in a multi-CEF report format.

Other implementation details on the base station side can be directly obtained by referring to the method on the UE side.

In method M400, the base station indicates the protocol version supported by the current base station by sending a protocol version indication to the UE, so that the UE can determine the corresponding CEF report format according to the protocol version supported by the base station, so that the base station can parse it according to the correct format CEF report sent by UE.

S410, the base station sends a protocol version indication to the UE, indicating the protocol version supported by the base station. Correspondingly, the UE receives the protocol version indication from the base station.

Specifically, the base station may use the protocol version indication to instruct the base station to support the protocol version corresponding to the multi-CEF report format (such as 3GPP R17). The protocol version indication may be carried in a master information block (master information block, MIB) or a system information block (system information block, SIB).

S420, the base station sends a CEF report request to the UE, where the CEF report request instructs the UE to send a CEF report. Correspondingly, the UE receives the CEF report request from the base station.

S430, the UE determines the format for sending the CEF report according to the protocol version indication.

S440, the UE sends a CEF report to the base station according to the determined format. Correspondingly, the base station receives the CEF report from the UE, and the base station parses the CEF report in a format corresponding to the protocol version supported by the base station.

Specifically, when the protocol version indication indicates that the base station supports the protocol version (such as R17) corresponding to the multi-CEF report format, the UE uses the multi-CEF report format to send the CEF report to the base station. Optionally, when the protocol version indication indicates that the protocol version supported by the base station does not support multiple CEF report formats (such as R16) or the UE does not receive the protocol version indication, the UE sends a CEF report to the base station in a single CEF report format.
