Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The technical solution of the present invention can be applied to various communication systems, such as: Global System of Mobile Communication (GSM), Code Division Multiple Access (CDMA) systems, and Wideband Code Division Multiple Access (GSM) systems. Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution/Enhanced Long Term Evolution (Long Term Evolution Advanced, LTE-A), NR, etc.

User-side UE can also be called terminal equipment (Mobile Terminal), mobile user equipment, etc., and can communicate with one or more core networks via a radio access network (RAN), and user equipment can be terminal equipment. Such as mobile phones (or "cellular" phones) and computers with terminal equipment. For example, they can be portable, pocket-sized, handheld, computer-built or vehicle-mounted mobile devices, which exchange languages and/or wireless access networks. Or data.

Network equipment, also called a base station, can be a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, or an evolved base station (evolutional Node B) in LTE , ENB or e-NodeB) and 5G base station (gNB).

In the technical solution of the present invention, the Minimization of Drive Tests (MDT) technology proposed by the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) organization is used to test the network quality. The feature of MDT technology is that it directly uses the UE in the network to measure and report the network coverage. In this way, by directly using the UE to test the network coverage, it avoids a large amount of manpower and material resources for operators, and can also cover the actual network users. Any place that can be reached, the network coverage involved is more effective than the traditional way of testing the signal quality of each location in the actual network by the operator using dedicated manpower and using dedicated instruments.

In addition, MDT technology also has the advantages of low overhead and short optimization cycle, which can greatly reduce the cost of network optimization and maintenance for mobile communication operators, and help improve the efficiency of network optimization. At the same time, because MDT technology can collect network information in places (such as indoors, narrow roads, etc.) that cannot be reached by traditional drive test methods. Therefore, MDT technology can provide more favorable support for evaluating network performance and improving network quality, which can bring higher satisfaction to users.

From the perspective of MDT measurement methods, MDT technology can be divided into immediate MDT (Immediate MDT) and logged MDT (Logged MDT). Among them, the recorded MDT refers to that the network device configures the recorded MDT measurement to the UE when the UE is in the RRC connected state. The UE performs measurement in the RRC idle state or the RRC inactive state, and records the measurement result. Further, the corresponding measurement result is reported to the network device only after the UE returns to the RRC connected state. The recorded MDT measurement can continue until the end of the MDT measurement duration configured by the network device.

The technical solutions provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, an embodiment of the present invention provides a measurement method, which is executed by a terminal device, and the method includes the following process steps:

Step 101: In the case of entering the radio resource control connection state, receive the recorded minimization drive test configuration information sent by the network device in the target public land mobile network (Public Land Mobile Network, PLMN), and the recorded MDT configuration information contains Measurement configuration information related to the frame timing difference.

Step 103: When the target PLMN enters the RRC idle state or the RRC inactive state from the RRC connected state, perform SFTD-related measurements on the target cell according to the measurement configuration information related to SFTD. The target cell and the recorded MDT configuration information correspond.

Wherein, the foregoing target cell corresponding to the foregoing MDT configuration information can be understood as the target cell being within the coverage of the MDT configuration information, or in other words, the target cell is a cell specified by the MDT configuration information. There may be one or more target cells.

In the embodiment of the present invention, the terminal device may receive the recorded MDT configuration information configured by the network device and sent in the target PLMN after entering the RRC connected state, and further may enter the RRC idle state or the RRC idle state from the RRC connected state in the target PLMN. After the RRC is in the inactive state, based on the SFTD-related measurement configuration information in the MDT configuration information, the SFTD-related measurement of the target cell within the coverage of the MDT configuration information is implemented. In this way, when the RRC connected state enters the RRC idle state or the RRC inactive state in the same PLMN, the corresponding measurement is performed according to the SFTD-related measurement configuration information configured when the network device is in the RRC connected state, and the terminal device is not connected in the RRC state. The data receiving and sending in the state has an impact, and the purpose of improving data throughput is achieved, thereby improving system efficiency.

The above-mentioned target PLMN may be identified by a globally unique PLMN code (globally unique PLMN code), and the globally unique PLMN code is composed of a mobile international number (Mobile Country Code, MCC) and a mobile network number (Mobile Network Code, MNC). Among them, MCC is composed of 3 decimal digits, indicating the country to which the mobile user belongs. For example, 460 represents China; MNC is composed of 2 to 3 decimal digits and is used to identify the mobile network to which the mobile user belongs. For example, the MNC of China Mobile is 00, 02, 04, 06.

Optionally, the measurement method in the embodiment of the present invention may further include the following content:

In the case of re-entering the RRC connected state in the target PLMN from the RRC idle state or the RRC inactive state, the first message sent by the network device is received; the second message is reported to the network device according to the first message, where the second message is used It bears the result of SFTD-related measurement on the target cell.

It can be understood that in the RRC idle state or the RRC inactive state, based on the measurement configuration information related to the SFTD configured by the network device, the corresponding measurement of the target cell within the coverage of the MDT configuration information is completed, and the RRC is re-entered in the target PLMN After the connected state, the result of the SFTD-related measurement on the target cell can be reported only when the first message is received from the network device, that is, the result of the SFTD-related measurement on the target cell is carried in the second message Report to the network side. That is to say, when the network side needs to report the results of SFTD-related measurements on the target cell, it not only helps the terminal device to efficiently switch from the current serving cell to the neighboring cell, but also saves power consumption on the terminal side. Purpose.

It should be noted that the cells corresponding to the RRC connected states that the terminal device enters before and after entering the RRC idle state or the RRC inactive state respectively belong to the same PLMN, and may be the same cell or different cells.

Optionally, in the measurement method of the embodiment of the present invention, the result of the foregoing SFTD-related measurement on the target cell includes but is not limited to at least one of the following:

(1) The system frame number (SFN) corresponding to the cell.

Optionally, when the terminal device enters the target cell, it can obtain the SFN corresponding to the target cell through a synchronization signal block (Synchronization Signal and PBCH block, SSB) corresponding to the target cell that is blindly detected.

(2) Inter-cell SFTD, where the SFTD includes at least one of the SFN offset and the frame boundary offset.

Optionally, when there are multiple target cells configured in the foregoing MDT configuration information, the result of performing SFTD-related measurements on the target cell may also include the SFTD of the cell. Wherein, the SFTD may include at least one of an SFN offset (SFN offset) and a frame boundary offset (Frame boundary offset).

Specifically, on the one hand, in a dual-connection scenario, SFTD can be used to enhance the synchronization performance between a master node (Master Node, MN) system and a secondary node (Secondary Node, SN) system. On the other hand, when the network node serving the UE cannot obtain the synchronization signal block measurement timing configuration (SSB Measurement Timing Configuration, SMTC) of the neighboring cell, the SFN offset between the serving cell and the neighboring cell can be obtained through measurement and The frame boundary offset is used to obtain the SMTC of the neighboring cell.

Further optionally, in the case that the serving cell of the terminal device does not have the SMTC of the neighboring cell, the above-mentioned SFTD can be used for the terminal device to obtain the SMTC of the neighboring cell by combining its SMTC. In this way, the result of the SFTD-related measurement on the target cell reported above may also include the SMTC of the neighboring cell. In this way, by realizing the measurement of the SMTC of the neighboring cell when entering the RRC idle state or the RRC inactive state, the efficiency of the terminal device handover to the neighboring cell can be improved. Wherein, the neighboring cell belongs to the aforementioned target cell.

Among them, the SMTC of each cell above refers to the SSB-based measurement timing configuration, that is, the configuration of the time window for the UE to measure the SSB. Among them, the configuration of the SMTC includes two variables: (1) the measurement duration (duration) configuration of the time window; (2) the measurement period and the time offset (periodicity and offset) configuration of the time window. Among them, the SMTC measurement period options include 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, and 160 ms; the SMTC measurement duration options include 1 ms, 2 ms, 3 ms, 4 ms, and 5 ms. millisecond. In order to reduce some unnecessary measurements or reduce the energy consumption of the UE, the measurement period of the time window corresponding to the SMTC can be configured to be different from the measurement period of the SSB according to different channel conditions. In this way, it is possible to avoid measuring the SSB too frequently, thereby reducing unnecessary measurements and reducing the energy consumption of the UE. In an example, when the measurement period of the SSB is 20 milliseconds, the network side can configure the UE with a measurement period of the time window corresponding to the SMTC of 40 milliseconds according to the current channel quality.

Optionally, in the measurement method of the embodiment of the present invention, before the step of receiving the first message sent by the network device is performed, the following content may be further included:

A third message is sent to the network device, where the third message is used for the network device to learn that the terminal device stores the result of the SFTD-related measurement on the target cell.

It can be understood that, in the RRC idle state or the RRC inactive state, based on the measurement configuration information related to the SFTD configured by the network device, after completing the corresponding measurement of the target cell within the coverage of the MDT configuration information, the first step can be sent to the network device. The third message actively informs the network equipment that the results of the SFTD-related measurement on the target cell are currently stored locally for the network equipment to determine whether the terminal equipment needs to report the results of the corresponding measurement, and further improve the system efficiency.
