[0002] In existing mobile communication systems, to save power, terminals such as Narrow Band Internet of Things (NB-IoT) terminals can refrain from measuring neighboring cells on the same or different frequencies, provided that the measurement values ​​of the serving cell meet the measurement relaxation criteria. Determining whether the measurement relaxation criteria are met generally requires judging whether the terminal is in a low-mobility state.

[0003] For a terminal in idle state, determining whether it is in a low-mobility state only requires considering the currently serving cell.

[0038] The method for determining low mobility states provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0039] The method for determining low mobility state in this application embodiment, in a scenario where the terminal is in a connected state, is configured with multiple serving cells. The terminal determines whether it is in a low mobility state based on the measurement result of one of the serving cells. On the one hand, the processing overhead of the terminal in determining the low mobility state is greatly reduced, and on the other hand, the terminal will not cause processing logic conflicts due to different judgment results from multiple serving cells.

[0040] Figure 2 This is one of the flowcharts illustrating the method for determining low mobility states provided in the embodiments of this application.

[0041] like Figure 2 As shown, the method for determining a low mobility state provided in this embodiment includes:

[0042] Step 101: When the terminal is configured with multiple serving cells, the terminal obtains the measurement result of the first serving cell; the first serving cell is one of the multiple serving cells.

[0043] Specifically, when a terminal is configured with multiple serving cells, in order to reduce the processing complexity of the terminal, the terminal can determine whether it is in a low mobility state based on the measurement results of the first serving cell among the multiple serving cells.

[0044] Optionally, the terminal may select a first serving cell based on the configuration of the network-side equipment. For example, the network-side equipment may indicate the serving cell or cell group used to determine the low mobility state; or, the network-side equipment may not explicitly indicate the serving cell or cell group used to determine the low mobility state. For example, the terminal may select the primary cell (PCell) or primary secondary cell (PSCell) among multiple serving cells; or, the terminal may select the first serving cell among multiple serving cells based on predetermined rules, such as selecting the serving cell with higher priority among multiple serving cells.

[0045] Step 102: Based on the measurement results of the first serving cell, the terminal determines that it is in a low mobility state.

[0046] Specifically, based on the measurement results of the first serving cell, the terminal determines whether it is in a low mobility state or not. A low mobility state refers to a state in which the terminal does not move or moves within a limited range.

[0047] For example, the measurement result of the first serving cell is compared with a certain measurement reference value. If the difference is small, the terminal is in a low mobility state; if the difference is large, the terminal is not in a low mobility state. The initial value of the measurement reference value can be configured by the network-side equipment or determined by the terminal itself. Optionally, the measurement reference value can also be updated based on the measurement results.

[0048] Optionally, a special case of the low mobility state is the stationary state.

[0049] In this embodiment, when a terminal is configured with multiple serving cells, the terminal determines that it is in a low mobility state based on the measurement results of a first serving cell among the multiple serving cells. This achieves the determination of a terminal's low mobility state when the terminal is configured with multiple serving cells. Moreover, since the determination of whether the terminal is in a low mobility state is based on the measurement results of only one serving cell, the processing complexity is low and the terminal's power consumption is low.

[0050] In one embodiment, the measurement result is the measurement result of at least one of the following reference signals:

[0051] Synchronization Signal and PBCH block (SSB);

[0052] Channel State Information Reference Signal (CSI-RS) used for time-frequency domain tracking;

[0053] CSI-RS is used to measure channel status.

[0054] CSI-RS for mobility measurement.

[0055] Optionally, the measurement results may include any one or a combination of the following:

[0056] Reference Signal Received Power (RSRP);

[0057] Reference Signal Received Quality (RSRQ);

[0058] Signal-to-interference-plus-noise ratio (SINR).

[0059] Optionally, when the measurement results are combined, at least the reference signal received power RSRP may be included.

[0060] Optionally, RSRP, RSRQ, or SINR are the measurement results after smoothing and filtering.

[0061] In one embodiment, the following steps may also be performed after step 102:

[0062] Based on the terminal being in a low mobility state, it is determined that measurement relaxation will be performed on the first serving cell; the measurement relaxation includes at least one of the following: Radio Link Monitoring (RLM) measurement relaxation, Beam Failure Detection (BFD) measurement relaxation, or Radio Resource Management (RRM) measurement relaxation.

[0063] Specifically, after the terminal is in a low mobility state, it can perform measurement relaxation for the first serving cell. Optionally, it can also perform measurement relaxation for other serving cells configured for the terminal. Measurement relaxation, for example, by increasing the measurement interval, can reduce the power consumption of the terminal.

[0064] In the above embodiments, when the terminal is in a low mobility state, the terminal can relax its measurement of the serving cell, that is, the measurement requirements are reduced, resulting in less power consumption of the terminal.

[0065] In one embodiment, the first serving cell is determined by the terminal based on the low mobility state judgment criteria sent by the network-side equipment.

[0066] The configuration methods for low mobility state judgment criteria include, for example, terminal-based configuration, cell group-based configuration, or serving cell-based configuration.

[0067] Specifically, "based on terminal configuration" means that the configuration level of the low mobility state judgment criteria is terminal-level, which means that the configuration applies to all serving cells of all cell groups of the terminal; "based on cell group configuration" means that the configuration level of the low mobility state judgment criteria is cell group-level, which means that the configuration applies to all serving cells of a specific cell group of the terminal; and "based on serving cell configuration" means that the configuration level of the low mobility state judgment criteria is serving cell-level, which means that the configuration applies to a specific serving cell of the terminal.

[0068] Specifically, network-side equipment can configure low mobility state judgment criteria based on the terminal, serving cell, or cell group. Under different configuration methods, the method for the terminal to select the first serving cell to determine the low mobility state may be different. Therefore, the terminal needs to learn from the network-side equipment the current low mobility state judgment criterion configuration method, and the terminal selects a first serving cell from multiple serving cells based on the configuration method.

[0069] like Figure 3 As shown, in step 100, the network-side device configures the low mobility state judgment criterion for the terminal, determines a first serving cell based on the configuration of the low mobility state judgment criterion, and determines that the terminal is in a low mobility state based on the measurement results of the first serving cell. Optionally, step 103 can also be performed, in which the terminal reports to the network-side device that the terminal is in a low mobility state.

[0070] Regarding the terminal-based configuration method, the low mobility state judgment criteria configured for the terminal are applicable to all cell groups. In particular, for a certain terminal, the low mobility state judgment criteria can be configured or not.

[0071] For cell group-based configuration, different cell groups are configured with their own low mobility state judgment criteria. The parameter values ​​for the low mobility state judgment criteria configured in different cell groups can be the same or different. In particular, for a given cell group, the low mobility state judgment criteria can be configured or not. If a cell group does not configure the low mobility state judgment criteria, then that cell group is not used to determine whether the terminal is in a low mobility state.

[0072] For the configuration method based on serving cell configuration, different serving cells are configured with low mobility state judgment criteria. In particular, for a given serving cell, the low mobility state judgment criterion can be configured or not. If a serving cell is not configured with the low mobility state judgment criterion, then the serving cell is not used to determine that the terminal is in a low mobility state, that is, the serving cell will not be used as the first serving cell.

[0073] In the above embodiments, the terminal can determine which of the multiple serving cells to use as the first serving cell based on the configuration of the low mobility state judgment criteria sent by the network-side equipment, which has low processing complexity.

[0074] In one embodiment, the first serving cell can be determined in the following ways:

[0075] One way

[0076] When the low mobility state determination criteria are configured based on terminal configuration,

[0077] In the case of a new NR primary cell PCell, the first serving cell is the NR PCell;

[0078] In the absence of an NR PCell, the first serving cell is the first primary / secondary cell PSCell configured on the network side.

[0079] Specifically, for the terminal-based configuration method, if there is an NR primary cell PCell among the multiple serving cells of the terminal, the PCell is taken as the first serving cell. Based on the measurement results of the PCell, the low mobility state of the terminal is determined, that is, whether it is in a low mobility state.

[0080] In cases where there is no primary NR cell PCell among the multiple serving cells of a terminal, for example, if the multiple serving cells are 4G serving cells, the first primary and secondary cell PSCell configured by the network-side equipment among the multiple serving cells is taken as the first serving cell. Based on the measurement results of this PSCell, the low mobility state of the terminal is determined, i.e., whether it is in a low mobility state.

[0081] NR is the common name for 5G air interface.

[0082] Another way

[0083] When the low mobility state judgment criterion is configured based on cell cluster configuration, the first serving cell is the primary cell PCell or the primary and secondary cell PSCell in the target cell cluster.

[0084] Specifically, for the configuration method based on cell clusters, the first serving cell used to determine whether the terminal is in a low mobility state can be the primary cell PCell or the primary and secondary cell PSCell in the target cell cluster; based on the measurement results of the primary cell PCell or the primary and secondary cell PSCell, the low mobility state of the terminal is determined, that is, whether it is in a low mobility state.

[0085] The target cell group is one of the cell groups among multiple serving cells. How the target cell group is selected will be explained in detail in subsequent embodiments.

[0086] Another way

[0087] When the low mobility state judgment criterion is configured based on the serving cell,

[0088] The first serving cell is the only serving cell configured by the network-side equipment based on cell measurement results to determine that the cell is in a low mobility state; or,

[0089] When network-side equipment is configured with low mobility state judgment criteria for multiple serving cells, the following situations apply:

[0090] The first scenario: The first serving cell is the first or most recent serving cell configured by the network-side equipment that is determined to be in a low mobility state based on cell measurement results; or,

[0091] The second scenario: The first serving cell is the second serving cell in the target cell group configured by the network-side equipment to determine whether a cell is in a low mobility state; wherein, the second serving cell is the only serving cell in the target cell group configured with the low mobility state judgment criterion; or,

[0092] The third scenario: The first serving cell is determined based on the priority of each serving cell configured on the network side equipment.

[0093] Specifically, for the configuration method based on serving cell configuration, the first serving cell can be the only serving cell configured by the network-side equipment to determine whether the terminal is in a low mobility state based on cell measurement results, or...

[0094] When the network-side equipment is configured with low mobility state judgment criteria in multiple serving cells, the terminal needs to determine which serving cell to use to determine whether the terminal is in a low mobility state based on other configuration information of the network-side equipment, that is, which serving cell is determined as the first serving cell.

[0095] In the first scenario, the first serving cell can be the first or most recent serving cell configured by the network-side device based on cell measurement results to determine that the terminal is in a low mobility state. For example, the network-side device may instruct serving cell 1, serving cell 2, and serving cell 3 to be configured with low mobility state judgment criteria. For instance, if only one serving cell is configured with low mobility state judgment criteria at a time, then serving cell 1 is the first serving cell configured with low mobility state judgment criteria. The most recent one refers to the serving cell in which the network-side device has recently configured low mobility state judgment criteria, such as the serving cell corresponding to the most recent configuration in the current time interval.

[0096] In the second scenario, the first serving cell is the second serving cell configured by the network-side equipment to determine the target cell group in a low mobility state; wherein, the second serving cell is the only serving cell in the target cell group that is configured with the low mobility state judgment criterion.

[0097] In the third scenario, the first serving cell can also be determined based on the priority of each serving cell. For example, the serving cell with the highest priority among the serving cells configured with low mobility status judgment criteria can be determined as the first serving cell. The terminal determines whether it is in a low mobility state based on the low mobility status judgment criteria configured in the highest priority serving cell.

[0098] Alternatively, for the third case, the serving cell used to determine the low mobility state can also be an SCell.

[0099] Alternatively, the target cell group can be determined in the following ways:

[0100] The target cell group is determined based on the target signaling messages sent by network-side devices; or,

[0101] The target cell group is the first, most recent, or only cell group configured with low mobility state judgment criteria by the network-side equipment; or,

[0102] The target cell group is determined based on the priority of each cell group configured on the network side equipment.

[0103] Specifically, the target signaling message may be an RRC Setup or RRC Reconfiguration signaling message sent by network-side equipment. This target signaling message can indicate the cell group used to determine the low mobility state.

[0104] Among them, the cell group most recently configured with low mobility state judgment criteria refers to the cell group in which the network-side equipment last configured the low mobility state judgment criteria.

[0105] The target cell group can also be determined based on the priority of each cell group. For example, the cell with the highest priority in the cell group configured with low mobility status judgment criteria can be determined as the target cell group.

[0106] The terminal determines whether it is in a low mobility state based on the relevant parameters of the low mobility state judgment criteria configured for the target cell group. These relevant parameters include, for example, duration, target threshold, priority parameters of the cell group, or priority parameters of the serving cell.

[0107] In the above embodiments, the terminal can select a first serving cell based on different configuration methods of the low mobility state judgment criteria, and then determine whether the terminal is in a low mobility state based on the measurement results of the first serving cell, which has low processing complexity.

[0108] In one embodiment, the method for determining the low mobility state further includes:

[0109] If the terminal is in a low mobility state when it is in an idle state, it reports the low mobility state to the network-side device after entering the connected state.

[0110] Specifically, if the terminal has performed relevant measurements on the frequency points of the primary cell PCell, primary / secondary cell PSCell, or secondary cell (SCell) in the idle state, for example, in the DC scenario or SCell scenario, the measurement can be an early measurement, and based on the low mobility state judgment criteria of the idle state, the terminal has determined that it is in a low mobility state in the idle state, then the terminal in the low mobility state can be reused in the connected state, that is, it is determined that the terminal is also in a low mobility state in the connected state, and after entering the connected state, the terminal reports to the network-side device that the terminal is in a low mobility state.

[0111] In the above embodiments, the result of the terminal being in a low mobility state as determined in the idle state is carried over to the connected state. The terminal no longer needs to make a judgment based on the measurement result, reducing unnecessary processing, thereby reducing the terminal's power consumption and saving processing time.

[0112] In one embodiment, step 102 can be implemented as follows:

[0113] If the measurement results of at least one reference signal in the first serving cell meet the low mobility state determination criteria, the terminal is determined to be in a low mobility state; or,

[0114] If the measurement results of all reference signals in the first serving cell meet the low mobility state judgment criteria, the terminal is determined to be in a low mobility state; or,

[0115] When multiple reference signals in the first serving cell are synchronization signal blocks (SSBs) with different indices or channel state information reference signals (CSI-RS) of the same type but different ports, the terminal is determined to be in a low mobility state based on the average or maximum value of the measurement results of multiple reference signals.

[0116] Optionally, the method for determining the low mobility state further includes:

[0117] If the measurement results of all reference signals in the first serving cell do not meet the low mobility state judgment criteria, the terminal is determined not to be in a low mobility state.

[0118] If the measurement results of at least one reference signal in the first serving cell do not meet the low mobility state judgment criteria, the terminal is determined to be not in a low mobility state.

[0119] Specifically, when there are multiple reference signals used to determine the low mobility state, if the measurement result of any one of the reference signals meets the low mobility state judgment criteria, then the terminal is in a low mobility state. For example, if the terminal has been in a low mobility state for a period of time, or if the terminal was not in a low mobility state before, then it enters the low mobility state. If the measurement results of all the reference signals fail to meet the low mobility state judgment criteria, then it is determined that the terminal is not in a low mobility state. For example, if the terminal has not been in a low mobility state for a period of time, or if the terminal was in a low mobility state before, then it exits the low mobility state.

[0120] When multiple reference signals exist for determining a low mobility state, if the measurement results of all of these reference signals meet the low mobility state judgment criteria, then the terminal is determined to be in a low mobility state. For example, if the terminal has been in a low mobility state for a period of time, or if the terminal was not in a low mobility state before, then it enters a low mobility state. If the measurement result of any one of these reference signals fails to meet the low mobility state judgment criteria, then the terminal is determined not to be in a low mobility state. For example, if the terminal has not been in a low mobility state for a period of time, or if the terminal was in a low mobility state before, then it exits a low mobility state.

[0121] When multiple reference signals exist for determining a low mobility state, and these reference signals are SSBs with different indices or CSI-RSs of the same type but different ports, the terminal determines whether it is in a low mobility state based on the average or maximum value of the measurement results of the multiple reference signals. For example, the average value of the measurement results of multiple reference signals is calculated and compared with the measured reference value. If the difference is small, the terminal is determined to be in a low mobility state; otherwise, it is not in a low mobility state.

[0122] The above implementation method enables the determination of a terminal in a low mobility state when multiple reference signals are present, and the implementation process is relatively simple.

[0123] In one embodiment, the low mobility state determination criterion is that the difference between the measurement reference value and the corrected value of the measurement result is less than or equal to the target threshold; the measurement reference value is obtained based on the cell measurement result when the terminal is in the connected state or the measurement reference value when it is in the idle state.

[0124] Specifically, the terminal determines whether it is in a low mobility state based on the measurement reference value Low_Mob_REF and the measurement result. If the difference between the terminal's measurement result Low_Mob_Meas and Low_Mob_REF is less than or equal to the target threshold, the terminal is in a low mobility state.

[0125] Determine if (Low_Mob_REF – Low_Mob_Meas) is satisfied. <SSearchDeltaP S SearchDeltaP This can be a target threshold configured in the network; if met, the terminal is in a low mobility state; if not met, the terminal is not in a low mobility state. Here, Low_Mob_REF is a measurement reference value.

[0126] Optionally, the terminal can determine whether to update Low_Mob_REF based on the measurement results in the connected state, and set Low_Mob_REF = Low_Mob_Meas if one or more of the following three conditions are met:

[0127] a. The UE has just entered the current first serving cell through cell selection or cell reselection, that is, this measurement is the first measurement of the terminal in the current first serving cell;

[0128] b.Low_Mob_Meas <Low_Mob_REF;

[0129] c. The terminal has been in use for some time (T) SearchDeltaP The low mobility condition judgment criterion was not met, and the timer duration T was extended. SearchDeltaP It can be configured via the network.

[0130] Optionally, if the low mobility criterion is also configured in the idle state and can be carried over to the connected state, the measurement reference value in the idle state can also be carried over to the connected state, that is, Low_Mob_REF is determined based on the measurement reference value Srxlev_Ref in the idle state.

[0131] Optionally, the initial Low_Mob_REF can be configured by the network-side device, or determined based on the cell measurement results when the terminal is in connected state, or the measurement reference value when it is in idle state.

[0132] For example, regarding the low mobility state determination criteria based on terminal configuration, such as in a connected CA / DC scenario, the method for determining the low mobility state includes the following steps:

[0133] Step 1a: Receive the relevant parameters of the low mobility state judgment criteria configured by the network-side equipment.

[0134] Relevant parameters include, for example, duration T. SearchDeltaP Target threshold S SearchDeltaPThe low mobility state determination criterion configuration can be effective for all CGs. For example, if the terminal can find the NR System Information Block (SIB), i.e., if the NR primary cell PCell exists, the low mobility state determination criterion can be directly configured in SIB2. If the terminal cannot find the NR SIB, i.e., if the NR primary cell PCell does not exist, the low mobility state determination criterion is given in a signaling (such as Radio Resource Control (RRC) signaling) loaded in the NR Secondary Cell Group (SCG). In this case, the network-side equipment can configure the low mobility state determination criterion only in the signaling of the first NR SCG configuration, and the terminal determines whether the terminal is in a low mobility state based on the PSCell in the NR SCG. The network-side equipment can also configure the corresponding low mobility criterion when configuring early measurement for the frequency point corresponding to the NR SCG.

[0135] Step 2a: Based on the measurement results in the connected state and the measurement reference value Low_Mob_REF, the terminal determines whether it is in a low mobility state.

[0136] Step 3a: When the terminal is in a low mobility state, the terminal enters the RLM / BFD / RRM measurement relaxation state.

[0137] For example, regarding the low mobility state judgment criteria based on cell cluster configuration, such as in a connected CA / DC scenario, the method for determining the low mobility state includes the following steps:

[0138] Step 1b: Receive the relevant parameters of the low mobility state judgment criteria configured by the network-side equipment.

[0139] Relevant parameters include, for example, duration T. SearchDeltaPThe target threshold is SSearchDeltaP. This low mobility state determination criterion is configured independently in each cell group (CG). When multiple CGs have the relevant parameters configured, i.e., multiple CGs have low mobility state determination criteria configured, the terminal determines the CG used by the terminal to determine if it is in a low mobility state based on other configurations of the network-side equipment. For example, the network-side equipment can explicitly indicate the CG used by the terminal to determine if it is in a low mobility state in the RRC Setup message or RRC Reconfig message; or, for example, the terminal can use the first, most recent, or only CG configured by the network-side equipment that has low mobility state determination criteria to determine if it is in a low mobility state. For example, this main parameter includes the priority configuration of the cell group. For instance, the terminal determines the parameters used to determine the low mobility state based on the low mobility state determination criteria configured in the highest priority CG, and thus determines whether the terminal is in a low mobility state. In this case, the first serving cell used to determine if it is in a low mobility state can be a Pcell or PSCell in this CG.

[0140] Step 2b: Based on the measurement results in the connected state and the measurement reference value Low_Mob_REF, the terminal determines whether it is in a low mobility state.

[0141] Step 3b: When the terminal is in a low mobility state, the terminal enters the RLM / BFD / RRM measurement relaxation state.

[0142] For example, regarding the low mobility state judgment criteria based on serving cell configuration, such as in a connected-state CA / DC scenario, the method for determining the low mobility state includes the following steps:

[0143] Step 1c: Receive the relevant parameters of the low mobility state judgment criteria configured by the network-side equipment.

[0144] Relevant parameters include, for example, duration T. SearchDeltaP Target threshold S SearchDeltaPThe low mobility state determination criterion is configured independently in each serving cell. Optionally, the network-side device configures the low mobility state determination criterion in only one serving cell. Optionally, the network-side device configures the low mobility state determination criterion in multiple serving cells, and the terminal needs to determine the serving cell used by the terminal to determine whether it is in a low mobility state based on other configuration information of the network-side device. For example, the terminal determines whether it is in a low mobility state based on the first or most recent serving cell configured by the network-side device that can determine whether it is in a low mobility state based on the measurement results, that is, the first or most recent serving cell configured by the network-side device that can determine whether it is in a low mobility state based on the measurement results is taken as the first serving cell; another example is that the terminal determines a target cell group for determining whether it is in a low mobility state based on the network-side device configuration, and selects a serving cell in the target cell group that has configured the low mobility state determination criterion to determine whether the terminal is in a low mobility state; there is only one serving cell in the target cell group that has configured the low mobility state determination criterion, and the method of determining the target cell group can be referred to the above embodiments. For example, this key parameter may also include cell priority configuration. For instance, the terminal determines relevant parameters based on the low mobility state judgment criteria configured in the highest-priority serving cell, thereby determining whether the terminal is in a low mobility state. In this case, the highest-priority serving cell could also be SCell.

[0145] Step 2c: Based on the measurement results in the connected state and the measurement reference value Low_Mob_REF, the terminal determines whether it is in a low mobility state.

[0146] Step 3c: When the terminal is in a low mobility state, the terminal enters the RLM / BFD / RRM measurement relaxation state.

[0147] Figure 4 This is the second flowchart illustrating the method for determining low mobility states provided in the embodiments of this application.

[0148] like Figure 4 As shown, the method for determining a low mobility state provided in this embodiment includes:

[0149] Step 201: The network-side equipment configures low mobility state judgment criteria for the terminal.

[0150] Step 202: The network-side device receives first indication information from the terminal. The first indication information is used to indicate that the terminal is in a low mobility state. The low mobility state is determined by the terminal based on the measurement results of the first serving cell and the low mobility state judgment criteria. The first serving cell is one of the multiple serving cells configured for the terminal.

[0151] Specifically, network-side equipment can configure low mobility state judgment criteria based on the terminal, serving cell, or cell group. When determining a low mobility state, the terminal needs to select a first serving cell from multiple serving cells based on the low mobility state judgment criteria. The terminal then determines whether it is in a low mobility state based on the measurement results of the first serving cell and the low mobility state judgment criteria. For example, it determines whether the measurement results of the first serving cell meet the low mobility state judgment criteria. If they do, the terminal is determined to be in a low mobility state; otherwise, it is determined that the terminal is not in a low mobility state.

[0152] In this embodiment, when a terminal is configured with multiple serving cells, the terminal determines that it is in a low mobility state based on the measurement results of a first serving cell among the multiple serving cells, and reports this to the network-side device. This achieves the determination of a terminal's low mobility state when the terminal is configured with multiple serving cells. Moreover, since the determination of whether the terminal is in a low mobility state is based on the measurement results of only one serving cell, the processing complexity is low and the terminal's power consumption is low.

[0153] Optionally, when the low mobility state determination criterion is configured based on terminal configuration,

[0154] In the presence of a new radio NR primary cell (PCell), the first serving cell is the NR PCell;

[0155] In the absence of the NR PCell, the first serving cell is the first primary / secondary cell PSCell configured on the network side.

[0156] Optionally, when the low mobility state judgment criterion is configured based on cell cluster configuration, the first serving cell is the primary cell PCell or the primary and secondary cell PSCell in the target cell cluster.

[0157] Optionally, when the low mobility state judgment criterion is configured based on serving cell configuration,

[0158] The first serving cell is the only serving cell configured by the network-side device to be in a low mobility state based on cell measurement results; or,

[0159] The first serving cell is the first or most recent serving cell configured by the network-side equipment that is determined to be in a low mobility state based on cell measurement results; or,

[0160] The first serving cell is a second serving cell in a target cell group configured by the network-side equipment to determine whether a cell is in a low mobility state; wherein, the second serving cell is the only serving cell in the target cell group configured to be in a low mobility state based on cell measurement results; or,

[0161] The first serving cell is determined based on the priority of each serving cell configured by the network-side equipment.

[0162] Optionally, the target cell group is determined based on target signaling messages sent by network-side equipment; or,

[0163] The target cell group is the first, most recent, or only cell group configured with low mobility state judgment criteria by the network-side equipment; or,

[0164] The target cell group is determined based on the priority of each cell group configured on the network side equipment.

[0165] Optionally, the method further includes the following steps:

[0166] The network-side device receives a second indication message from the terminal. The second indication message is sent by the terminal when it enters the connected state and is used to indicate that the terminal is in a low mobility state. The low mobility state indicated by the second indication message is determined by the terminal in the idle state.

[0167] Optionally, if the measurement result of at least one reference signal of the first serving cell meets the low mobility state judgment criterion, the terminal is in a low mobility state.

[0168] The terminal is in a low mobility state if the measurement results of all reference signals in the first serving cell meet the low mobility state judgment criteria.

[0169] If the measurement results of all reference signals in the first serving cell do not meet the low mobility state judgment criteria, the terminal is not in a low mobility state.

[0170] If the measurement result of at least one reference signal in the first serving cell does not meet the low mobility state judgment criteria, the terminal is not in a low mobility state.

[0171] When the multiple reference signals in the first serving cell are synchronization signal blocks (SSBs) with different indices or channel state information reference signals (CSI-RS) of the same type but different ports, the low mobility state of the terminal is determined based on the average or maximum value of the measurement results of the multiple reference signals.

[0172] Optionally, the low mobility state judgment criterion is that the difference between the measurement reference value and the measurement result is less than or equal to a first threshold; the measurement reference value is obtained based on the cell measurement result or is the measurement reference value when the terminal is in an idle state.

This achieves the determination of the terminal's low mobility state when the terminal is configured with multiple serving cells. Moreover, since the determination of whether the terminal is in a low mobility state is based on the measurement results of only one serving cell, the processing complexity is low and the terminal's power consumption is low.

It is understood that the aforementioned modem processor may also not be integrated into processor 1010.

[0236] The processor 1010 is configured to acquire the measurement result of a first serving cell when the terminal is configured with multiple serving cells; the first serving cell is one of the multiple serving cells.

[0237] Based on the measurement results, the terminal determines that it is in a low mobility state.

[0238] In this embodiment, when the terminal is configured with multiple serving cells, the terminal's processor determines that the terminal is in a low mobility state based on the measurement results of a first serving cell among the multiple serving cells. This achieves the determination of the terminal's low mobility state when the terminal is configured with multiple serving cells. Moreover, since the determination of whether the terminal is in a low mobility state is based on the measurement results of only one serving cell, the processing complexity is low and the terminal's power consumption is low.

[0239] Optionally, the first serving cell is determined by the terminal based on the low mobility state judgment criteria sent by the network-side equipment.

[0240] In the above embodiments, the terminal can determine which of the multiple serving cells to use as the first serving cell based on the configuration of the low mobility state judgment criteria sent by the network-side equipment, which has low processing complexity.

[0241] Optionally, when the low mobility state determination criterion is configured based on terminal configuration,

[0242] In the case of a new NR primary cell (PCell), the first serving cell is the NR PCell;

[0243] In the absence of the NR PCell, the first serving cell is the first primary / secondary cell PSCell configured by the network-side equipment; or...

[0244] When the low mobility state determination criterion is configured based on cell cluster configuration, the first serving cell is the primary cell PCell or primary / secondary cell PSCell in the target cell cluster; or, when the low mobility state determination criterion is configured based on serving cell configuration,

[0245] The first serving cell is the only serving cell configured by the network-side device to be in a low mobility state based on cell measurement results; or,

[0246] The first serving cell is the first or most recent serving cell configured by the network-side equipment that is determined to be in a low mobility state based on cell measurement results; or,

[0247] The first serving cell is a second serving cell in a target cell group configured by the network-side equipment to determine those in a low mobility state; wherein, the second serving cell is the only serving cell in the target cell group configured with low mobility state judgment criteria; or,

[0248] The first serving cell is determined based on the priority of each serving cell configured by the network-side equipment.

[0249] Optionally, the target cell group is determined based on target signaling messages sent by network-side equipment; or,

[0250] The target cell group is the first, most recent, or only cell group configured with low mobility state judgment criteria by the network-side equipment; or,

[0251] The target cell group is determined based on the priority of each cell group configured on the network side equipment.

[0252] In the above embodiments, the terminal can select a first serving cell based on different configuration methods of the low mobility state judgment criteria, and then determine whether the terminal is in a low mobility state based on the measurement results of the first serving cell, which has low processing complexity.

[0253] Optionally, the processor 1010 is also used for:

[0254] If the terminal is determined to be in a low mobility state while it is in an idle state, it reports the low mobility state to the network-side device after entering the connected state.

[0255] In the above embodiments, the result of the terminal being in a low mobility state as determined in the idle state is carried over to the connected state. The terminal no longer needs to make a judgment based on the measurement result, reducing unnecessary processing, thereby reducing the terminal's power consumption and saving processing time.

[0256] Optionally, the processor 1010 is specifically used for:

[0257] If the measurement results of at least one reference signal in the first serving cell meet the low mobility state judgment criteria, the terminal is determined to be in a low mobility state.

[0258] If the measurement results of all reference signals in the first serving cell meet the low mobility state judgment criteria, the terminal is determined to be in a low mobility state.

[0259] When multiple reference signals in the first serving cell are synchronization signal blocks (SSBs) with different indices or channel state information reference signals (CSI-RS) of the same type but different ports, the terminal is determined to be in a low mobility state based on the average or maximum value of the measurement results of the multiple reference signals.

[0260] Optionally, the processor 1010 is also used for:

[0261] If the measurement results of all reference signals in the first serving cell do not meet the low mobility state judgment criteria, it is determined that the terminal is not in a low mobility state.

[0262] If the measurement result of at least one reference signal in the first serving cell does not meet the low mobility state judgment criteria, the terminal is determined not to be in a low mobility state.

[0263] The above implementation method enables the determination of a terminal in a low mobility state when multiple reference signals are present, and the implementation process is relatively simple.

[0264] Optionally, the low mobility state judgment criterion is the difference between the measurement reference value and the measurement result, which is less than or equal to a target threshold; the measurement reference value is obtained based on the cell measurement result when the terminal is in a connected state or the measurement reference value when it is in an idle state.

[0265] This application also provides a network-side device, including a processor and a communication interface. The processor is used to configure low mobility state judgment criteria for a terminal, and the communication interface is used to receive first indication information from the terminal.
