Technical Field
[0001] The present application relates to the field of communication technology, and in particular to a communication method, device and terminal. Background Art
[0002] The 3GPP protocol specifies the R16 relaxed measurement criteria and the R17 relaxed measurement criteria. The R16 relaxed measurement criteria means that if both the R16 low mobility criteria and the R16 non-cell edge criteria are met, the neighboring cell measurement can be relaxed to once an hour. The R17 relaxed measurement criteria means that if the R17 stationary non-cell edge criteria are met, the neighboring cell measurement can be relaxed to once every four hours. However, in actual applications, when a terminal enters a connected state while in a relaxed measurement state and then releases to a non-connected state again, the power consumption is relatively high. Summary of the invention
[0003] The present application provides a communication method, device and terminal, which solve the problem in the prior art that when a terminal enters a connected state while in a relaxed measurement state and then releases to a non-connected state again, power consumption is high.
[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

When the first relaxation measurement parameter is the same as the second relaxation measurement parameter, and the difference between the first signal quality parameter and the second signal quality parameter is within a preset range, the terminal enters a relaxation measurement state, the second relaxation measurement parameter is the relaxation measurement parameter corresponding to the last time the terminal entered the relaxation measurement state, and the second signal quality parameter is the signal quality parameter corresponding to the last time the terminal entered the relaxation measurement state.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0041] In the embodiments of the present application, the step numbers do not represent the order in which the steps are executed, but are intended to distinguish the steps as different steps.
[0042] First, the application scenarios of the embodiments of the present application are introduced. Figure 1 A schematic diagram of a communication system provided in an embodiment of the present application. The technical solution of the embodiment of the present application can be applied to Figure 1 The communication system shown may include a network device and a terminal communicating with the network device. Figure 1 A network device and a terminal communicating with the network device are shown. In fact, the communication system may include multiple terminals, which is not limited in the embodiments of the present application.
[0043] Among them, the network device can be a device that can communicate with the terminal, for example, the network device can be a radio access network (RAN) device, which is a device that provides wireless communication functions for the terminal. Access network equipment includes but is not limited to: the next generation base station (generation nodeB, gNB) in 5G, evolved nodeB (evolved nodeB, eNB), baseband unit (baseband unit, BBU), transmitting and receiving point (transmitting and receiving point, TRP), transmitting point (transmitting point, TP), base station in future mobile communication system or access point in WiFi system, etc. The access network device can also be a wireless controller, centralized unit (centralized unit, CU), and / or distributed unit (distributed unit, DU) in the cloud radio access network (cloud radio access network, CRAN) scenario.
[0044] A terminal, also referred to as a terminal device or user equipment (UE), includes a device that provides voice and / or data connectivity to a user, and may include, for example, a handheld device with a wireless connection function, or a processing device connected to a wireless modem. The terminal may communicate with a core network via a radio access network (RAN) and exchange voice and / or data with the RAN. The terminal may include a wireless terminal device, a mobile terminal device, a device-to-device communication (D2D) terminal device, a machine-to-machine / machine-type communications (M2M / MTC) terminal device, an Internet of Things (IoT) terminal device, a subscriber unit, a subscriber station, a mobile station, a remote station, an access point (AP), a remote terminal, an access terminal, a user terminal, a user agent, an aircraft (such as a drone, a hot air balloon, a civil airliner, etc.) or a user device, etc. Specifically, the terminal may include a mobile phone (or "cellular" phone), a computer with a mobile terminal device, a portable, pocket-sized, handheld, or computer-built-in mobile device, etc. For example, a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), and other devices.

[0045] In addition, the embodiments of the present application may also be applicable to other future-oriented communication technologies. The network architecture and service scenarios described in this application are intended to more clearly illustrate the technical solutions of this application, and do not constitute a limitation on the technical solutions provided by this application. It is known to those skilled in the art that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by this application are also applicable to similar technical problems.
[0046] The new radio (NR) system includes three radio resource control (RRC) states: connected, idle, and inactive. The inactive state is used to meet the requirements of low latency and low power consumption. Figure 2 A schematic diagram of RRC state transition provided for an embodiment of the present application. When the terminal is in an idle state, an RRC connection can be established, converted to a connected state, and returned to the idle state by releasing the RRC connection. When a terminal in a connected state is in a low demand state, the release of the RRC connection can be delayed, converted to an inactive state, and returned to the idle state by releasing the RRC connection. Depending on the RRC state between the terminal and the network device, the terminal can be in a connected state, an idle state, or an inactive state.
[0047] Figure 3 A schematic diagram of a cell provided for an embodiment of the present application. The terminal can move between cell 1, cell 2, and cell 3. Due to the mobility of the terminal, the terminal may move from the coverage of one cell to the coverage of another cell. In order to ensure the service continuity and communication quality of the terminal, the terminal needs to perform cell reselection or cell handover. The terminal obtains continuous service of the wireless network by reselecting and handing over between cells with different coverage.
[0048] The terminal performs cell reselection and cell switching through radio resource management (RRM) measurement. Specifically, the terminal determines whether it is within the coverage of a certain cell through RRM measurement, receives reference signals sent from multiple network devices, and completes cell reselection or cell switching based on the power of the reference signal.
[0049] For the terminal, no matter it is in connected, idle or inactive state, in order to obtain a service cell with better communication quality, the terminal needs to measure the signal strength of the surrounding neighboring cells, including the same-frequency cell, different-frequency cell and different-system cell. If the neighboring cell measurement is frequent, the power consumption of the terminal is high.
[0050] The 5G communication protocol introduces the concept of relaxed measurement. Relaxed measurement allows the terminal to reduce the measurement frequency, reduce the measurement time, and extend the measurement period of periodic measurement. If the terminal is in a low mobility state and not at the cell edge, or the terminal is stationary and not at the cell edge, the terminal can enter the relaxed measurement state and extend the neighboring cell measurement period to 1 hour or 4 hours.
[0051] In actual applications on existing networks, when a terminal is in a non-connected state (idle state and inactive state), it usually performs periodic registration every 50 minutes, or often receives or sends heartbeat packets, causing the terminal to enter a connected state and exit a relaxed measurement state. When the terminal is released to a non-connected state again, it is necessary to re-evaluate the relaxed measurement. Relaxed measurement evaluation means that within a specified time, the terminal receives a preset number of indication messages from the service area, and determines whether the terminal meets the relaxed measurement criteria based on the preset number of indication messages. If each indication message meets the relaxed measurement criteria, the terminal enters the relaxed measurement state again. The following is combined with Figure 4 The process is described in detail. Figure 4 The figure is a flow chart of a terminal entering a relaxed measurement state.
[0052] S110: The terminal is in a disconnected state and enters a relaxed measurement state.
[0053] S120: within the relaxed measurement period (eg, 4 hours), due to periodic registration, or receiving a heartbeat packet, or user use of the terminal, the terminal enters the connected state and exits the relaxed measurement state.
[0054] S130: The terminal is released to the non-connected state again and is in a normal measurement state. The terminal being in a normal measurement state may mean that the terminal has not entered a relaxed measurement state.
[0055] S140: When the terminal is in a non-connected state and in a normal measurement state, the terminal re-performs a relaxed measurement evaluation. The terminal receives a preset amount of indication information from the service area.
[0056] S150: The terminal determines whether the terminal meets the relaxed measurement criterion according to a preset amount of indication information.
[0057] S160: If yes, the terminal enters a relaxed measurement state. If not, the terminal executes S140 and re-performs a relaxed measurement evaluation until the terminal passes the relaxed measurement evaluation and enters a relaxed measurement state. In practical applications, step S150 for judging may not exist, and S160 is executed when each indication information in a preset number of indication information meets the relaxed measurement criteria, or when there is at least one indication information in a preset number of indication information that does not meet the relaxed measurement criteria, S140 is executed. The embodiments of the present application do not limit this.
[0058] Therefore, in practical applications, it is difficult for the terminal to relax the neighboring cell measurement to once an hour or once every four hours. Each time it is released to the non-connected state, although the energy and position of the terminal have not changed, it is difficult to quickly enter the relaxed measurement state, and a long time is required to evaluate the relaxed measurement criteria, which consumes a lot of power.
[0059] Based on this, an embodiment of the present application provides a communication method. Figure 5 A communication method according to an embodiment of the present invention is provided. Figure 1 The method comprises:
[0060] S210: The terminal receives indication information of a first cell in a first non-connected state, where the indication information is used to indicate a first signal quality parameter and a first relaxed measurement parameter of the first cell, where the first signal quality parameter is used to indicate communication signal quality between the terminal and the first cell.
[0061] S220: When the first relaxation measurement parameter is the same as the second relaxation measurement parameter, and the difference between the first signal quality parameter and the second signal quality parameter is within a preset range, the terminal enters a relaxation measurement state, the second relaxation measurement parameter is the relaxation measurement parameter corresponding to the last time the terminal entered the relaxation measurement state, and the second signal quality parameter is the signal quality parameter corresponding to the last time the terminal entered the relaxation measurement state.
[0062] The first cell may be a service area where the terminal resides. The base station managing the first cell may continuously broadcast system information to the terminal in the first cell, and the terminal residing in the first cell may continuously receive system information from the first cell.
[0063] Furthermore, the second relaxed measurement parameter may specifically be: a relaxed measurement parameter corresponding to the last time the terminal was in a non-connected state and entered a relaxed measurement state. The second signal quality parameter may specifically be: a signal quality parameter corresponding to the last time the terminal was in a non-connected state and entered a relaxed measurement state. The first signal quality parameter and the second quality parameter are both used to indicate the communication signal quality between the terminal and the first cell.
[0064] The first relaxed measurement parameter is the same as the second relaxed measurement parameter, and the difference between the first signal quality parameter and the second signal quality parameter is within a preset range, which means that the energy and position of the terminal have not changed, and the terminal meets the relaxed measurement criterion.
[0065] and Figure 4 Compared with the scheme in Figure 4 In the scheme, when the terminal enters the connection state when it is in the relaxed measurement state, and then releases to the non-connected state again, it is necessary to receive a preset number of indication information from the first cell. It is determined whether each of the multiple indication information satisfies the relaxed measurement criterion. This process needs to last for a long time. In the technical scheme provided by the embodiment of the present application, when the terminal enters the connection state when it is in the relaxed measurement state, and then releases to the non-connected state again, it only needs to receive the first indication information from the first cell, and when the first relaxation measurement parameter indicated by the first indication information is the same as the second relaxation measurement parameter, and the difference between the first signal quality parameter indicated by the first indication information and the second signal quality parameter is within a preset range, the relaxed measurement state is entered. On the one hand, the terminal only needs to receive one first indication information, and does not need to receive a preset number of multiple indication information, which takes a short time. On the other hand, the terminal only needs to enter the relaxed measurement state when the first relaxation measurement parameter indicated by the first indication information is the same as the second relaxation measurement parameter, and the difference between the first signal quality parameter indicated by the first indication information and the second signal quality parameter is within a preset range. There is no need to determine whether the relaxed measurement criterion is met, and the computing power required by the terminal is small. On the other hand, the terminal can quickly enter the relaxed measurement state, reduce the number of neighboring cell measurements, reduce power consumption, and save power consumption caused by repeatedly evaluating whether the terminal meets the relaxed measurement criteria.
[0066] In a possible implementation, the indication information includes a first synchronization signal block (SSB) and first system information, the first synchronization signal block is used to indicate the first signal quality parameter, and the first system information is used to indicate the first relaxation measurement parameter.
[0067] Among them, the quality of the SSB signal sent by the base station will deteriorate as the distance between the base station and the terminal increases. Therefore, the first signal quality parameter indicated by the SSB signal can be used to indicate the communication signal quality between the terminal and the first cell.
[0068] In the technical solution provided in the embodiment of the present application, the first cell sends the first synchronization signal block and the first system information to the terminal, thereby indicating the first signal quality parameter and the first relaxation measurement parameter. In this way, a basis is provided for reducing the time for the terminal to enter the relaxation measurement, reducing the terminal computing power, and reducing the terminal power consumption.
[0069] In one possible implementation, the terminal enters a relaxed measurement state, including: the terminal receives a second synchronization signal block from a second cell at a first frequency, the second synchronization signal block is used to indicate the communication signal quality between the terminal and the second cell, the second cell is a neighboring cell of the first cell, the first frequency is less than the second frequency, and the second frequency is the frequency of receiving the second synchronization signal block when the terminal has not entered the relaxed measurement state.
[0070] Among them, the terminal enters the relaxed measurement state, that is, the neighboring area measurement frequency of the terminal is reduced. Specifically, when the terminal does not enter the relaxed measurement state, the terminal receives the SSB signal from the second cell at the second frequency, thereby monitoring the communication quality between the terminal and the neighboring area. After the terminal enters the relaxed measurement state, the terminal receives the SSB signal from the second cell at the first frequency, and the first frequency is lower than the second frequency.
[0071] In the technical solution provided in the embodiment of the present application, the terminal enters the relaxed measurement state, including: the terminal receives the second synchronization signal block from the neighboring cell at a lower first frequency, thereby reducing the frequency of neighboring cell measurement. In this way, a basis is provided for reducing the power consumption of the terminal.
[0072] In a possible implementation, the indication information is also used to indicate a first minimum resident threshold, and the first minimum resident threshold is used to indicate the minimum energy or minimum quality required to reside in the first cell. Before the terminal enters the relaxed measurement state, the method also includes: determining that the first signal quality parameter, the first minimum resident threshold and the first relaxed measurement parameter meet the relaxed measurement criterion.

S210 may specifically include S211: the terminal receives indication information of the first cell in the first non-connected state, the indication information is used to indicate the first signal quality parameter, the first relaxed measurement parameter of the first cell and the first minimum residence threshold. S220 may specifically include S221: when the first relaxed measurement parameter is the same as the second relaxed measurement parameter, the difference between the first signal quality parameter and the second signal quality parameter is within a preset range, and the first signal quality parameter, the first minimum residence threshold and the first relaxed measurement parameter meet the relaxed measurement criteria, the terminal enters a relaxed measurement state.
[0074] In the technical solution provided in the embodiment of the present application, before the terminal enters the relaxed measurement state, it is determined that the first signal quality parameter, the first minimum dwell threshold and the first relaxed measurement parameter meet the relaxed measurement criterion. In this way, it is further determined that the terminal meets the relaxed measurement criterion to improve accuracy.
[0075] Exemplarily, the signal quality parameter indicated by the SSB signal may include reference signal receiving power (RSRP) or reference signal receiving quality (RSRQ).
[0076] The system information may include a system information block 1 (SIB1) signal and a system information block 2 (SIB2) signal. The SIB1 signal may be used to indicate a minimum resident threshold, wherein the minimum resident threshold includes a minimum access threshold Rxlev min and minimum quality threshold Qual min .Rxlev min It means: the minimum energy required for the terminal to stay in the cell that sends the SIB1 signal. min It refers to the minimum quality required for the terminal to reside in the cell that sends the SIB1 signal.
[0077] The R16 low mobility criteria are described below.
[0078] The R16 low mobility criterion means that if the energy measured by the terminal changes very little and is within the specified range 1, it means that the terminal is in a low-speed mobile state. If the energy measured by the terminal changes greatly and exceeds the specified range 1, it means that the terminal is in a high-speed mobile state.

[0081] The formula for the R16 low mobility criterion is as follows:
[0082] When (Srxlev Ref -Srxlev) SearchDeltaP When , the terminal meets the low mobility criterion. Where Srxlev is the current Srxlev value of the service area. Srxlev Ref is the reference Srxlev value of the service area. Ref The setting method is: after selecting or reselecting a new cell, or when (Srxlev-Srxlev Ref )>0, or when T SearchDeltaP If the relaxed measurement criteria are not met, the terminal will set the Srxlev Ref The value of is set to the current Srxlev value of the service area.
[0083] After introducing the R16 low mobility criterion, the R16 non-cell edge criterion is introduced below.
[0084] The R16 non-cell edge criterion means that if the energy measured by the terminal is greater than the specified range 2, and the quality is greater than the specified range 3, it means that the terminal's signal is very strong and is located in the center of the cell.
[0085] The cell selection parameters corresponding to the R16 non-cell edge criterion include: Srxlev, cell selection reception quality value Squal (also known as cell residence quality). For example, Squal = RSRQ-Qual min .

[0087] The formula for the R16 non-cell edge criterion is as follows:
[0088] When Srxlev>S SearchThresholdP , and Squal>S SearchThresholdQ When (if S SearchThresholdQ configured), the terminal meets the non-cell edge criterion. Where Srxlev is the current Srxlev value of the service area. Squal is the current Squal value of the service area.
[0089] If the terminal in idle or inactive state meets both the low mobility criteria and the non-cell edge criteria, the neighboring cell measurement of the same frequency, different frequency and different system can be relaxed to once an hour.
[0090] The protocol describes the R16 idle state relaxation measurement as follows:
[0091] This clause contains the measurement requirements for intra-frequency NR cells, provided that: the terminal is configured with both low mobility criteria and non-cell edge criteria, and the terminal meets both criteria, and it is less than 1 hour since the last cell reselection measurement. In this case, the terminal does not need to meet the T defined in Table 4.2.3-1. detect,NR_Intra , Tmeasure,NR_Intra and T evaluate,NR_Intra .

[0093] The method further comprises: according to the reference signal received power RSRP and the minimum access threshold Rxlev min , determine the cell selection reception level value Srxlev and the cell selection reception level reference value Srxlev Ref .
[0094] The first signal quality parameter, the first minimum dwell threshold and the first relaxed measurement parameter satisfying the relaxed measurement criterion include: the cell selection reception level reference value Srxlev Ref The difference between the cell selection reception level value Srxlev and the cell selection reception level value Srxlev is less than the cell selection reception level value search power difference parameter S SearchDeltaP , and the cell selection reception level value Srxlev is greater than the first cell selection reception level value search power threshold S SearchThresholdP .
[0095] If the terminal receives S SearchDeltaP and S SearchThresholdP No change has occurred and according to RSRP and Rxlev min If the obtained Srxlev meets the R16 low mobility criterion and the R16 non-cell edge criterion, the terminal can relax the neighboring cell measurement to once per hour.

[0097] In a possible implementation manner, the first signal quality parameter further includes a reference signal received quality RSRQ, and the first minimum dwell threshold includes a minimum quality threshold Qual min The first relaxation measurement parameter also includes a first cell selection reception level value search quality threshold, and the first cell selection reception level value search quality threshold may be S SearchThresholdQ .
[0098] The method further comprises: according to the reference signal reception quality RSRQ and the minimum quality threshold Qual min , determine the cell selection reception quality value Squal.
[0099] The relaxed measurement criteria are also satisfied: the cell selection reception quality value Squal is greater than the first cell selection reception level value search quality threshold S SearchThresholdQ .
[0100] In the technical solution provided in the embodiment of the present application, according to RSRQ and Qual min Determine Squal, satisfying the relaxed measurement criteria except including: (Srxlev Ref -Srxlev) SearchDeltaP , and Srxlev>S SearchThresholdP In addition, it also includes: Squal>S SearchThresholdQ In this way, it is further ensured that the signal quality of the terminal meets the relaxed measurement criteria and the accuracy is improved.
[0101] The R17 stationary criterion is introduced below.
[0102] The R17 stationary criterion means that if the energy measured by the terminal changes very little and is within the specified range 4, it means that the terminal is in a stationary state.

[0104] The relaxed measurement parameters corresponding to the R17 static criterion include: cell selection receiving level value search power difference static parameter S SearchDeltaP-Stationary , Time search power difference static parameter T SearchDeltaP-Stationary .
[0105] The formula for the R17 stationary criterion is as follows:
[0106] When (Srxlev RefStationary -Srxlev) SearchDeltaP-Stationary When , the terminal meets the low mobility criterion. Where Srxlev is the current Srxlev value of the service area. Srxlev RefStationary is the reference Srxlev value of the service area. RefStationary The setting method is: after selecting or reselecting a new cell, or when (Srxlev-SrxlevRefStationary )>0, or when T SearchDeltaP-Stationary If the relaxed measurement criteria are not met, the terminal will set the Srxlev RefStationary The value of is set to the current Srxlev value of the service area.
[0107] After introducing the R17 stationary criterion, the R17 stationary non-cell edge criterion is introduced below.
[0108] The R17 stationary non-cell edge criterion means that, based on the stationary criterion, if the energy measured by the terminal is greater than a specified range of 5, and the quality is greater than a specified range of 6, it indicates that the terminal is stationary and located at the center of the cell.

[0111] The formula for the R17 stationary non-cell edge criterion is as follows:
[0112] (Srxlev RefStationary -Srxlev) SearchDeltaP-Stationary ;
[0113] In T SearchDeltaP-Stationary During this specified time, if Srxlev>S SearchThresholdP2 , and Squal>S SearchThresholdQ2 , (if S SearchThresholdQ2 If the terminal satisfies the static non-cell edge criterion, Srxlev is the current Srxlev value of the service area, and Squal is the current Squal value of the service area.
[0114] If the terminal in the idle or inactive state meets the static non-cell edge criterion, the neighboring cell measurement of the same frequency, different frequency and different system can be relaxed to once every 4 hours.
[0115] The protocol describes the R17idle state relaxation measurement as follows:

This clause contains measurement requirements for intra-frequency NR cells, provided that: the terminal is configured with stationary criteria and non-cell-edge criteria, and the terminal meets both criteria, and it is less than 4 hours since the last cell reselection measurement. The requirements defined in this clause apply regardless of the eDRX_IDLE configuration. In this case, the terminal does not need to meet the T defined in clause 4.2B.2.3. detect,NR_Intra , T measure,NR_Intra_RedCap and T evaluate,NR_Intra_RedCap .
