Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The technical scheme of the invention can be applied to various communication systems, such as: global system for mobile communications (Global System of Mobile communication, GSM), code division multiple access (Code Division Multiple Access, CDMA) system, wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), general packet radio service (General Packet Radio Service, GPRS), long term evolution/enhanced long term evolution (Long Term Evolution Advanced, LTE-a), NR, etc.

The user equipment UE, which may also be referred to as a Terminal equipment (Mobile Terminal), a Mobile user equipment, etc., may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), and the user equipment may be Terminal equipment, such as Mobile phones (or "cellular" phones) and computers with Terminal equipment, for example, portable, pocket, hand-held, computer-built-in or vehicle-mounted Mobile devices, which exchange speech and/or data with the radio access network.

The network device, which may be referred to as a base station, may be a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolved base station (evolutional Node B, eNB or e-NodeB) in LTE, or a 5G base station (gNB).

In the technical scheme of the invention, the network quality is tested by adopting a minimization of drive test (Minimization of Drive Tests, MDT) technology proposed by a third generation partnership project (3rd Generation Partnership Project,3GPP) organization. The MDT technology is characterized in that UE in a network is directly used for measuring and reporting network coverage conditions, so that the coverage conditions of the network are tested by directly utilizing the UE, a great amount of manpower and material resource expenses of operators are avoided, any place which can be reached by a user in the network can be covered, and the related network coverage is more effective compared with a traditional drive test mode that the operators start special manpower to use special instruments to the actual network to test the signal quality of each place.

In addition, the MDT technology has the advantages of small cost, short optimization period and the like, so that the cost of network optimization and maintenance of a mobile communication carrier can be greatly reduced, and the efficiency of network optimization can be improved. Meanwhile, the MDT technology can collect network information of places (such as indoor places, narrow roads and the like) which cannot be reached by the traditional drive test mode. Thus, the MDT technique may provide more advantageous support for evaluating network performance and improving network quality, which may lead to higher satisfaction for the user.

From the perspective of the MDT measurement mode, the MDT technique can be divided into immediate MDT (Immediate MDT) and recorded MDT (Logged MDT). The logged MDT refers to that when the network device is in RRC connected state, the UE is configured with logged MDT measurement. And the UE performs measurement in an RRC idle (idle) state or an RRC inactive (inactive) state and records a measurement result. And reporting the corresponding measurement result to the network equipment after the UE returns to the RRC connection state. The logged MDT measurement may continue until the network device configured MDT measurement duration ends.

The following describes in detail the technical solutions provided by the embodiments of the present invention with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides a measurement method, which is performed by a terminal device, and includes the following steps:

step 101: in case of entering a radio resource control RRC connected state, receiving logged minimization of drive tests MDT configuration information sent by the network device in the target public land mobile network (Public Land Mobile Network, PLMN), the logged MDT configuration information comprising measurement configuration information related to the frame timing difference SFTD.

Step 103: and under the condition that the RRC connection state enters the RRC idle state or the RRC non-activated state in the target PLMN, according to the measurement configuration information related to the SFTD, carrying out SFTD related measurement on the target cell, wherein the target cell corresponds to the recorded MDT configuration information.

The target cell corresponding to the MDT configuration information may be understood that the target cell is within a coverage area of the MDT configuration information, or the target cell is a cell designated by the MDT configuration information. The number of the target cells may be one or more.

Wherein the target PLMN is identified by a globally unique PLMN code (globally unique PLMN code) consisting of a mobile international number (Mobile Country Code, MCC) and a mobile network number (Mobile Network Code, MNC). Wherein the MCC consists of a 3-digit decimal number indicating the country to which the mobile subscriber belongs, e.g., 460 represents China; MNCs consist of 2 to 3 decimal numbers for identifying the mobile networks to which the mobile subscriber belongs, such as MNCs moving in china are 00, 02, 04, 06.

Optionally, the measuring method of the embodiment of the present invention may further include the following:

receiving a first message sent by the network device in case of re-entering the RRC connected state in the target PLMN by the RRC idle state or the RRC inactive state; and reporting a second message to the network equipment according to the first message, wherein the second message is used for bearing 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 measurement configuration information related to SFTD configured by the network device, after completing corresponding measurement on a target cell within a coverage range of the MDT configuration information and entering the RRC connected state in the target PLMN again, a result of SFTD related measurement on the target cell may be reported only when an indication of the network device, that is, a first message is received, that is, a result of SFTD related measurement on the target cell is carried in a second message and reported to the network side. That is, reporting is performed when the network side needs to perform SFTD related measurement on the target cell, which is not only helpful for the terminal device to switch from the current serving cell to the neighboring cell efficiently, but also can achieve the purpose of saving the power consumption of the terminal side.

The cells corresponding to the RRC connection states respectively entered by the terminal device before and after entering the above RRC idle state or the RRC inactive state belong to the same PLMN, and may be the same cell or different cells.

Optionally, in the measurement method according to the embodiment of the present invention, the results of SFTD related measurement on the target cell include, but are not limited to, at least one of the following:

(1) And (5) a system frame number (system frame number, SFN) corresponding to the cell.

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

(2) SFTD between cells, the SFTD comprising at least one of SFN offset and frame boundary offset.

Optionally, when the number of the target cells configured in the MDT configuration information is plural, the result of performing SFTD related measurement on the target cells may further include SFTD of the cells. Wherein the SFTD may include at least one of an SFN offset (SFN offset) and a frame boundary offset (Frame boundary offset).

In particular, in one aspect, SFTD may be used to enhance synchronization performance between a Master Node (MN) system and a Secondary Node (SN) system in a dual connectivity scenario. On the other hand, when the network node serving the UE cannot acquire the synchronization signal block measurement timing configuration (SSB Measurement Timing Configuration, SMTC) of the neighboring cell, the SMTC of the neighboring cell may be acquired by measuring the SFN offset and the frame boundary offset between the serving cell and the neighboring cell.

Further alternatively, in the case that the serving cell of the terminal device does not have SMTC of the neighboring cell, the SFTD may be used for the terminal device to obtain SMTC of the neighboring cell in combination with SMTC back-pushing. As such, the results reported to SFTD related measurements on the target cell may also include SMTC of the neighbor cell. Thus, by implementing the measurement of SMTC of the neighboring cell when entering the RRC idle state or the RRC inactive state, the efficiency of the terminal device switching to the neighboring cell can be improved. Wherein the neighbor cell belongs to the target cell.

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

Optionally, in the measurement method according to the embodiment of the present invention, before the step of receiving the first message sent by the network device, the method may further include the following:

and sending a third message to the network equipment, wherein the third message is used for the network equipment to know that the terminal equipment stores a result of SFTD related measurement on the target cell.

It can be understood that after completing the corresponding measurement of the target cell in the coverage range of the MDT configuration information based on the SFTD related measurement configuration information configured by the network device in the RRC idle state or the RRC inactive state, the network device may actively inform the network device that the result of the SFTD related measurement is locally stored in the target cell by sending a third message to the network device, so that the network device determines whether the reporting of the corresponding measurement result is required by the terminal device, thereby further improving the system efficiency.

Referring to fig. 2, an embodiment of the present invention provides a measurement method, which is performed by a network device, and includes the following steps:

step 201: and under the condition that the terminal equipment enters a Radio Resource Control (RRC) connection state, sending the recorded MDT configuration information to the terminal equipment in the target Public Land Mobile Network (PLMN).

The recorded MDT configuration information includes measurement configuration information related to a frame timing difference SFTD, where the measurement configuration information related to SFTD is used for performing SFTD related measurement on a target cell when the terminal device enters an RRC idle state or an RRC inactive state from an RRC connected state in a target PLMN, and the target cell corresponds to the recorded MDT configuration information.

In the embodiment of the invention, the network device can send the configured recorded MDT configuration information to the terminal device entering the radio resource control RRC in the target public land mobile network PLMN, and the measurement configuration information related to the frame time sequence difference SFTD in the MDT configuration information can be used for the terminal device to realize the measurement related to the SFTD of the target cell within the coverage range of the MDT configuration information after entering the RRC idle state or the RRC inactive state from the RRC connection state in the target PLMN. In this way, the network device configures measurement configuration information related to SFTD when in RRC connection state, so that the terminal can perform corresponding measurement when entering RRC idle state or RRC inactive state from RRC connection state in the same PLMN, the data receiving and transmitting of the terminal device in RRC connection state can not be influenced, the purpose of improving data throughput can be achieved, and system efficiency is improved.

Wherein the target PLMN is identified by a globally unique PLMN code (globally unique PLMN code) comprising a mobile international number MCC and a mobile network number MNC. Wherein the MCC consists of a 3-digit decimal number indicating the country to which the mobile subscriber belongs, e.g., 460 represents China; MNCs consist of 2 to 3 decimal numbers for identifying the mobile networks to which the mobile subscriber belongs, such as MNCs moving in china are 00, 02, 04, 06.

Optionally, in the measurement method according to the embodiment of the present invention, the following may be further included:

sending a first message to a terminal device; and under the condition that the terminal equipment re-enters the RRC connection state in the target PLMN from the RRC idle state or the RRC inactive state, receiving a second message reported by the terminal equipment according to the first message, wherein the second message is used for bearing the result of SFTD related measurement on the target cell.

It may be appreciated that the network device may instruct the terminal device to report, when necessary, a result of SFTD related measurement on the target cell based on the SFTD related measurement configuration information configured by the network device in the RRC idle state or the RRC inactive state, that is, may obtain the result of SFTD related measurement on the target cell by receiving the second message reported by the terminal device. Therefore, the terminal equipment can be effectively switched from the current service cell to the adjacent cell, and the purpose of saving the power consumption of the terminal side can be achieved.

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

Optionally, when the terminal device enters the target cell, the SFN corresponding to the target cell may be obtained through the synchronization signal block SSB corresponding to the target cell that is blindly detected.

In particular, in one aspect, SFTD may be used to enhance synchronization performance between a primary node MN system and a secondary node SN system in a dual connectivity scenario. On the other hand, when the network node serving the UE cannot acquire the synchronization signal block measurement timing configuration SMTC of the neighboring cell, the SMTC of the neighboring cell may be acquired by measuring the SFN offset and the frame boundary offset between the serving cell and the neighboring cell.

Further alternatively, in the case that the serving cell of the terminal device does not have SMTC of the neighboring cell, the SFTD may be used for the terminal device to obtain SMTC of the neighboring cell in combination with SMTC back-pushing. As such, the results reported to SFTD related measurements on the target cell may also include SMTC of the neighbor cell. Therefore, the efficiency of switching the terminal equipment to the adjacent cell can be improved by enabling the terminal equipment to measure the SMTC of the adjacent cell when entering the RRC idle state or the RRC inactive state. Wherein the neighbor cell belongs to the target cell.

Optionally, in the measuring method according to the embodiment of the present invention, the following may be further included:

the method comprises sending results of SFTD related measurements of the target cell to a target object comprising at least one of a first network device, a relay node, a trace acquisition entity (Trace Collection Entity, TCE), a gateway, a mobility management entity (Mobility Management Entity, MME) and an access mobility management function (Access Management Function, AMF) entity.

It can be understood that, by sharing the measurement result of the target cell, which is reported by the terminal device and is based on the measurement configuration information related to SFTD configured by the network device, to other network nodes in the RRC idle state or the RRC inactive state, unnecessary repeated measurement can be avoided, thereby improving system efficiency.

Optionally, in the measurement method of the embodiment of the present invention, the step of sending the first message to the terminal device may be performed as follows:

and under the condition that a third message sent by the terminal equipment is received, sending the first message to the terminal equipment, wherein the third message is used for the network equipment to know that the terminal equipment stores the result of SFTD-related measurement on the target cell.

It can be understood that, when the third message reported by the terminal device explicitly knows that the result of SFTD related measurement on the target cell is currently stored in the local area, the terminal device is instructed to report the result of SFTD related measurement on the target cell based on measurement configuration information configured by the network device in the RRC idle state or the RRC inactive state, so as to further improve system efficiency.
