Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a radio resource management (RRM) measurement method, an RRM measurement configuration method, a terminal device, and a network-side device. Background Technology

[0002] When the User Equipment (UE) is in the center of the serving cell or has low mobility, given that the probability of the UE performing cell reselection or handover is low at this time, the Radio Resource Management (RRM) measurement relaxation mode can be enabled to reduce power consumption.

[0003] However, in related technologies, the UE uses independent RRM measurement relaxation criteria in connected and disconnected states. As a result, the RRM measurement relaxation mode cannot be continuous when the UE's Radio Resource Control (RRC) state changes. For example, when the UE determines to enable the RRM measurement relaxation mode according to the connected state RRM measurement relaxation criteria, if the UE enters the disconnected state, it needs to first switch to the normal RRM measurement mode, and then, according to the disconnected state RRM measurement relaxation criteria, it can only re-enable the RRM measurement relaxation mode when it determines to enable it again.

[0004] As can be seen from the above, in the relevant technologies, when the RRC state of the UE changes, it causes unnecessary or long-term interruption of the RRM measurement relaxation mode. Summary of the Invention

[0016] The first sending module is used to send first configuration information to the terminal device;

[0017] Wherein, the first configuration information is used to configure the terminal device to perform RRM measurement in the second RRC state by adopting the target RRM measurement mode according to the first configuration information when it enters the second RRC state from the first RRC state.

[0018] Fifthly, a terminal is provided, the terminal including a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the method described in the first aspect.

[0019] In a sixth aspect, a terminal is provided, including a processor and a communication interface, wherein the communication interface is used to acquire first configuration information, and the processor is used to perform RRM measurement in the second RRC state according to the first configuration information when the terminal device enters a second RRC state from a first RRC state.

[0020] In a seventh aspect, a network-side device is provided, the network-side device including a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein the program or instructions, when executed by the processor, implement the steps of the method as described in the third aspect.

[0021] Eighthly, a network-side device is provided, including a processor and a communication interface, wherein the communication interface is used to send first configuration information to a terminal device;

[0022] The first configuration information is used to configure the terminal device to perform RRM measurement in the second RRC state by adopting the target RRM measurement mode according to the first configuration information when it enters the second RRC state from the first RRC state.

[0023] A ninth aspect provides a readable storage medium on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect, or implement the steps of the method described in the third aspect.

[0024] In a tenth aspect, a chip is provided, the chip including a processor and a communication interface coupled to the processor, the processor being configured to run programs or instructions to implement the method as described in the first aspect, or to implement the method as described in the third aspect.

It should be noted that in this application embodiment, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0047] In related technologies, RRM measurement relaxation can reduce terminal power consumption. Furthermore, in these technologies, the RRM measurement relaxation criteria for connected and disconnected states are configured and evaluated independently. Specifically, a disconnected UE is evaluated according to the disconnected state RRM measurement relaxation criteria, and RRM measurement relaxation is performed in the disconnected state if the evaluation result meets the criteria. Conversely, a connected UE is evaluated according to the connected state RRM measurement relaxation criteria, and RRM measurement relaxation is performed in the connected state if the evaluation result meets the criteria. This results in a situation where, when a UE transitions from a disconnected state to a connected state, even if the UE was already determined to be located in the cell center or stationary in the disconnected state, thus meeting the disconnected state RRM measurement relaxation criteria and allowing RRM measurement relaxation, RRM measurement still needs to be performed in the connected state, and evaluated according to the connected state RRM measurement relaxation criteria. Only after meeting the criteria can RRM measurement be relaxed.

[0048] RRM measurements in both connected and disconnected states have the following benefits:

[0049] I. RRM Measurement in a Connected State

[0050] In disconnected mode, RRM measurements are used to assist in UE mobility management. For example, when the signal quality of a neighboring cell is better than that of the serving cell, the UE will be triggered to reselect to the neighboring cell in RRC IDLE or RRC Inactive mode. RRM measurements are achieved by the UE measuring the signal quality of the serving cell and neighboring cells at a certain frequency. In practice, the higher the RRM measurement frequency, the higher the UE power consumption, but the more promptly the UE can detect changes in signal quality and trigger reselection to a suitable serving cell (i.e., better mobility performance). Generally speaking, the probability of a terminal located in the cell center and / or with low mobility reselecting to a neighboring cell is much lower than that of a terminal located at the cell edge and / or with high mobility. Therefore, by appropriately relaxing RRM measurements for terminals with low reselection probability, UE power consumption can be effectively reduced with limited reduction in mobility performance. For example, the aforementioned RRM measurement relaxation scheme may include: extending the measurement period (reducing the measurement frequency) or reducing the number of Layer 1 measurement samples in RRM measurement relaxation mode to reduce UE power consumption.

[0051] Prior to this, the UE could determine whether RRM measurement relaxation was permissible based on the criteria for determining the RRM measurement relaxation mode. These criteria could include the following two principles:

[0052] First criterion: The terminal is not located at the cell edge.

[0053] like Figure 2a As shown, under this first judgment criterion, the network side is configured with a Reference Signal Received Power (RSRP) threshold (i.e., as shown in the figure). Figure 2a The threshold S shown in the figure SearchThresholdP When the terminal's RSRP on the serving cell is greater than S SearchThresholdP If so, the terminal is considered to meet the first judgment criterion.

[0054] Typically, the network configuration uses S for the first judgment criterion. SearchThresholdP Less than S IntrasearchP and S nonIntrasearchP S IntrasearchP This indicates that the RSRP of the terminal on the serving cell is greater than S. IntrasearchP In this case, the terminal may not need to perform co-frequency measurements; S nonIntrasearchP This indicates that the RSRP of the terminal on the serving cell is greater than S. nonIntrasearchP In this case, the terminal may not need to perform inter-frequency measurements.

[0055] Additionally, the network side can be configured with a Reference Signal Received Quality (RSRQ) threshold (i.e., a judgment threshold S). SearchThresholdQ At this time, when the terminal's RSRQ on the serving cell is greater than S... SearchThresholdQ And RSRP is greater than S SearchThresholdP If the terminal meets the first judgment criterion, it is considered that the terminal is not located at the cell edge.

[0056] Typically, the network configuration uses S for the first judgment criterion. SearchThresholdQ Also smaller than S IntrasearchQ and S nonIntrasearchQ .

[0057] Second judgment criterion: Low mobility criterion

[0058] like Figure 2b As shown, under this second judgment criterion, the evaluation time T for changes in the network-side RSRP configuration is... SearchDeltaP and RSRP change threshold S SearchDeltaP When a period of time T SearchDeltaP Within, the change in RSRP of the terminal on the serving cell is less than S. SearchDeltaP If the terminal meets the second judgment criterion, it is considered that the terminal has low mobility or is in a stationary state.

[0059] In existing technologies, after completing cell selection / reselection, the terminal needs to wait for at least a period of time T. SearchDeltaP Perform normal RRM measurements internally to determine whether the second judgment criterion is met based on the results of the normal RRM measurements.

[0060] The above two sets of criteria are based on cell-level measurement results of the terminal in the serving cell. Based on network configuration, the UE can relax RRM measurement when one or both of the above criteria are met.

[0061] II. RRM Measurement in Connected State

[0062] For terminals in RRC Connected state, the network side can configure RRM measurement relaxation criteria. When the UE detects that the criteria are met, the UE can report that the criteria are met. At this time, the network side can configure the UE to enable the RRM measurement relaxation scheme.

[0063] Compared to the off-state RRM measurement relaxation mechanism, the connected state mechanism adds the steps of UE reporting that measurement criteria are met and the network side configuring the UE to enable the RRM measurement relaxation scheme. This makes the network side's control over the UE's RRM measurement relaxation more stringent and precise.

[0064] This is because if the mobility performance of a connected UE cannot be guaranteed, it will lead to a poor user experience (such as call interruption); therefore, the network side needs to have stricter control over connected UEs.

[0065] As can be seen from the above, in the relevant technologies, because the RRM measurement relaxation criteria for connected and disconnected states are configured and evaluated independently, after the UE undergoes an RRC state change, it is necessary to re-evaluate the RRM measurement relaxation criteria. This will cause unnecessary measurements and delay the timing for the UE to initiate RRM measurement relaxation, resulting in unnecessary power consumption.

[0066] In this embodiment, the appropriate RRM measurement mode can be determined based on pre-acquired first configuration information in the second RRC state. This allows the terminal device to perform RRM measurements in the second RRC state using the corresponding RRM measurement mode when transitioning from the first RRC state. Unlike existing technologies, this eliminates the need to re-evaluate the RRM measurement relaxation criteria after entering the second RRC state. Therefore, this embodiment accelerates the activation of the RRM measurement relaxation mode upon entering the second RRC state, reduces unnecessary interruptions to the RRM measurement relaxation mode, and minimizes power consumption of the terminal device.

[0067] The RRM measurement method, RRM measurement configuration method, terminal device, and network-side device provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0068] Please see Figure 3 This application provides an RRM measurement method, wherein the subject executing the RRM measurement method can be a terminal device, such as... Figure 3 As shown, the RRM measurement method may include the following steps:

[0069] Step 301: The terminal device obtains the first configuration information.

[0070] Step 302: When the terminal device enters the second RRC state from the first RRC state, it performs RRM measurement in the second RRC state according to the first configuration information using the target RRM measurement mode.

[0071] In specific implementation, the terminal device can receive the first configuration information from the network-side device. For example, the terminal device can receive the first configuration information in the first RRC state or the second RRC state, and determine the target RRM measurement mode based on the first configuration information.

[0072] In specific implementation, the target RRM measurement mode mentioned above may include an RRM measurement relaxation mode. Of course, when the triggering conditions of the RRM measurement relaxation mode are not met, the target RRM measurement mode may also be a normal RRM measurement mode. In addition, the target RRM measurement mode may also be an RRM measurement enhancement mode, etc. For ease of explanation, the following embodiments take the target RRM measurement mode as the RRM measurement relaxation mode as an example for illustration.

[0073] One of the first and second RRC states mentioned above can be a disconnected state, and the other can be a connected state. The disconnected state can include an idle state and an inactive state.

[0074] In addition, the aforementioned first configuration information can be used to configure at least one of the following:

[0075] Configure the terminal device to enable the target RRM measurement mode in the second RRC state;

[0076] Configure the terminal device to report information related to enabling the target RRM measurement mode in the second RRC state;

[0077] The criteria for determining whether the terminal device enables the target RRM measurement mode in the second RRC state;

[0078] Configure the measurement scheme for the target RRM measurement mode enabled by the terminal device in the second RRC state.

[0079] Scenario 1

[0080] When the first configuration information is used to configure the terminal device to enable the target RRM measurement mode in the second RRC state, the terminal device directly enables the target RRM measurement mode when entering the second RRC state.

[0081] Scenario 2

[0082] When the first configuration information is used to configure the terminal device to report related to enabling the target RRM measurement mode in the second RRC state, the terminal device reports the measurement results related to the RRM measurement relaxation criteria when entering the second RRC state, so that the network can determine whether to enable the target RRM measurement mode.

[0083] Scenario 3

[0084] When the first configuration information is used to configure the judgment criteria for enabling the target RRM measurement mode in the second RRC state, the terminal device can evaluate according to the above judgment criteria for enabling the target RRM measurement mode in the second RRC state before entering the second RRC state, so as to determine whether to enable the target RRM measurement mode after entering the second RRC state.

[0085] The criteria for activating the target RRM measurement mode may include at least one of the "low mobility" criterion (i.e., the first criterion) and the "not located at the cell edge" criterion (i.e., the second criterion). In practical applications, the UE's mobility and whether it is located at the cell center are usually unrelated to the UE's RRC status.

[0086] In this embodiment, when the terminal device enters the second RRC state from the first RRC state, the characteristics of the UE detected in the first RRC state, such as mobility and whether it is located in the cell center, are compared with the judgment criteria for enabling the target RRM measurement mode in the second RRC state. If the judgment criteria for enabling the target RRM measurement mode in the second RRC state are met, the target RRM measurement mode is enabled when entering the second RRC state.

[0087] For example, if the first RRC state is RRC connected and the second RRC state is RRC disconnected, the first configuration information can be received in the RRC connected state. This first configuration information can be used to configure which judgment criterion the terminal device uses to determine whether to adopt the RRM measurement relaxation mode when leaving the RRC connected state. In this way, the terminal device knows how to determine whether to enable the RRM measurement relaxation mode in the second RRC state from the first RRC state. Therefore, if it is determined that the RRM measurement relaxation mode is enabled in the RRC disconnected state before or when entering the second RRC state, RRM measurement relaxation can be performed immediately upon entering the RRC disconnected state, without needing to re-evaluate according to the RRM measurement relaxation criteria in the RRC disconnected state after entering the RRC disconnected state.

[0088] For example, if the first RRC state is RRC disconnected and the second RRC state is RRC connected, the first configuration information (e.g., system information broadcast by the serving cell) can be received in the RRC disconnected state. In this case, the first configuration information can be used to configure which judgment criterion to use to determine whether to adopt the RRM measurement relaxation mode when / after entering the RRC connected state. In this way, the terminal device learns the RRM measurement relaxation criteria in the second RRC state from the first RRC state, and can determine whether the RRM measurement relaxation criteria are met in the RRC connected state before or after entering the second RRC state. If the determination result is that the RRM measurement relaxation criteria are met, the relevant information can be reported as soon as possible upon entering the RRC connected state, without needing to re-evaluate according to the RRM measurement relaxation criteria in the RRC connected state after entering the RRC connected state.

[0089] Scenario 4

[0090] When the first configuration information is used to configure the measurement scheme of the target RRM measurement mode enabled by the terminal device in the second RRC state, the terminal device can directly perform RRM measurement according to the above-mentioned measurement scheme of the target RRM measurement mode when entering the second RRC state. For example, RRM measurement relaxation can be performed according to the measurement relaxation scheme in the RRM measurement relaxation mode. The measurement relaxation scheme may specifically include: reducing the measurement frequency, reducing the number of samples, etc., which are not specifically limited here.

[0091] Of course, the first configuration information mentioned above can also be configured with at least two of the above situations one to four. For example, the judgment criteria and measurement scheme of the target RRM measurement mode enabled by the terminal device in the second RRC state can be configured at the same time. In this way, when the terminal device determines that the judgment criteria of the target RRM measurement mode enabled in the second RRC state are met, it will use the above measurement scheme to perform RRM measurement when entering the second RRC state.

[0092] Furthermore, the aforementioned first configuration information can also configure relevant judgment parameters for the terminal device to determine whether the relaxed measurement criterion for RRM is met in the second RRC state. For example: Figure 2a and Figure 2b The judgment thresholds S shown correspond to RSRP and RSRQ in the RRM measurement relaxation criteria, respectively. SearchThresholdP S SearchThresholdQ T SearchDeltaP S SearchDeltaP In practice, if a cell is configured with the aforementioned judgment parameters for determining whether the RRM measurement relaxation criteria are met, it means that the UE serving that cell is allowed to perform RRM measurement relaxation. At this time, the terminal device can perform the evaluation process related to the RRM measurement relaxation criteria, and if it is determined that the RRM measurement relaxation criteria are met, it can perform RRM measurement relaxation for that cell.

[0093] In specific implementation, the target RRM measurement mode in the first configuration information can be determined based on the RRM measurement status of the terminal device in the first RRC state.

[0094] For example, the target RRM measurement mode indicated in the first configuration information to be enabled in the second RRC state can be the same as the RRM measurement mode enabled by the terminal device in the first RRC state, for example, both being RRM measurement relaxation modes. In this way, unnecessary interruption of RRM measurement relaxation can be avoided when the terminal device performs RRC state transition.

[0095] Furthermore, the RRM measurement status includes at least one of the following:

[0096] Whether to enable RRM measurement relaxation mode in the first RRC state;

[0097] The measurement and relaxation scheme corresponding to the RRM measurement and relaxation mode used in the first RRC state;

[0098] The RRM measurement relaxation criterion corresponding to the RRM measurement relaxation mode activated in the first RRC state.

[0099] Scenario 1

[0100] The RRM measurement status includes: whether the RRM measurement relaxation mode is enabled in the first RRC status.

[0101] At this time, if the RRM measurement relaxation mode is enabled in the first RRC state, the terminal device determined accordingly will enable the RRM measurement relaxation mode in the second RRC state; if the RRM measurement relaxation mode is not enabled in the first RRC state, the terminal device determined accordingly will not enable the RRM measurement relaxation mode in the second RRC state, that is, it will enable the normal RRM measurement mode.

[0102] Scenario 2

[0103] The RRM measurement state includes: the measurement relaxation scheme corresponding to the RRM measurement relaxation mode used in the first RRC state:

[0104] At this time, the terminal device can use the same or similar measurement relaxation scheme to perform RRM measurement relaxation in the second RRC state.

[0105] Scenario 3

[0106] The RRM measurement state includes: the RRM measurement relaxation criterion corresponding to the RRM measurement relaxation mode activated in the first RRC state:

[0107] At this point, when the terminal enters the second RRC state, it can determine whether the RRM measurement relaxation criterion is met based on the same RRM measurement relaxation criterion.

[0108] The RRM measurement relaxation criteria may include at least one of the first and second judgment criteria mentioned above. In some cases, the terminal device can assess its own mobility status, such as being in a state of low mobility (e.g., moving at low speed or stationary); at the same time, the terminal can also assess its relative position in the serving cell (e.g., whether it is located at the cell edge). It can then be determined whether the assessment result meets the RRM measurement relaxation criteria.

[0109] Specifically, the RRM measurement relaxation criteria can instruct the terminal device which parameters need to be measured, such as the RSRP and RSRQ of the serving cell. Then, based on the comparison between the measured RSRP and RSRQ and the corresponding judgment thresholds, it determines whether the RRM measurement relaxation criteria are met, such as being stationary, not at the cell edge, or having low mobility. At this point, the network side can configure the terminal to perform RRM measurement relaxation when entering the second RRC state, based on the terminal device's reported compliance with the RRM measurement relaxation criteria.

[0110] Furthermore, the RRM measurement relaxation criteria in the first RRC state and the RRM measurement relaxation mode in the second RRC state can correspond to the same or different judgment thresholds, respectively. For example, the mobility time threshold in the idle state is Threshold_IDLE = a, and the mobility time threshold in the connected state is Threshold_Conn = b, where b can be equal to a + Delta. Thus, if Delta = 0, the mobility time thresholds in the idle and connected states are the same; if Delta ≠ 0, the mobility time thresholds in the idle and connected states are different.

[0111] It should be noted that the above RRM measurement status may also include at least two of the above situations one to three. For example, the RRM measurement status may include: whether the RRM measurement relaxation mode is enabled in the first RRC state and the measurement relaxation scheme corresponding to the RRM measurement relaxation mode adopted in the first RRC state; or, the RRM measurement status may include: whether the RRM measurement relaxation mode is enabled in the first RRC state and the RRM measurement relaxation criterion corresponding to the RRM measurement relaxation mode enabled in the first RRC state; or, the RRM measurement status may include: the measurement relaxation scheme corresponding to the RRM measurement relaxation mode adopted in the first RRC state and the RRM measurement relaxation criterion corresponding to the RRM measurement relaxation mode enabled in the first RRC state; or, it may include all three of the above items. Furthermore, the RRM measurement status may also include other RRM measurement information, which is not specifically limited here.

[0112] As an optional implementation, before the terminal device obtains the first configuration information, the method further includes:

[0113] The terminal device sends the RRM measurement status under the first RRC state to the network-side device.

[0114] In this embodiment, the terminal device sends the RRM measurement status in the first RRC state to the network-side device, and the network-side device determines the target RRM measurement mode to be enabled in the second RRC state based on this status, such as whether to enable RRM measurement relaxation in the second RRC state, and sends the determination result to the terminal through the first configuration information mentioned above, so that the terminal device can enable the corresponding RRM measurement mode according to the network-side configuration.

[0115] Furthermore, the target RRM measurement mode includes an RRM measurement relaxation mode, wherein the terminal device sends the RRM measurement status under the first RRC state to the network-side device, including:

[0116] When the terminal device enables the RRM measurement relaxation mode in the first RRC state, it sends the RRM measurement status in the first RRC state to the network-side device.

[0117] In this embodiment, the terminal device will only report the RRM measurement status in the first RRC state if the RRM measurement relaxation mode is enabled in the first RRC state; correspondingly, if the terminal device does not enable the RRM measurement relaxation mode in the first RRC state, the terminal device may not report the RRM measurement status in the first RRC state. In this way, unnecessary interruptions of the RRM measurement relaxation mode can be avoided during the RRC state change process, while also reducing signaling overhead.

[0118] Assuming the first RRC state is disconnected and the second RRC state is connected, the terminal device can send the RRM measurement status in the first RRC state to the network-side device in the following way:

[0119] Method 1

[0120] When the terminal device establishes an RRC connection with the network-side device and completes security activation, it encrypts and reports the RRM measurement status in the disconnected state based on the encryption requirements of the network-side device.

[0121] In this implementation, when the terminal device performs RRC Connection Setup to transition from an RRC disconnected state to an RRC connected state, the terminal device can report its pending information in the RRC setup completion message. After the terminal device is securely activated, it encrypts and reports the RRM measurement status in the disconnected state based on the encryption requirements of the network-side device.

[0122] Method 2

[0123] When the terminal device establishes an RRC connection with the network-side device, it carries the unencrypted RRM measurement status in the non-connection state in the RRC establishment completion message sent to the network-side device.

[0124] In this embodiment, when the terminal device establishes an RRC connection to transition from an RRC disconnected state to an RRC connected state, the terminal device can report the RRM measurement status information from the disconnected state in the RRC establishment completion message.

[0125] Method 3

[0126] When the terminal device restores its connection with the network-side device's RRC, it encrypts and reports the RRM measurement status in the disconnected state based on the encryption requirements of the network-side device.

[0127] In this implementation, when the terminal device performs RRC Connection Resume to transition from an RRC disconnected state to an RRC connected state, the terminal device can report its pending information in the RRC recovery completion message. Then, based on the encryption requirements of the network-side device, the RRM measurement status in the disconnected state is encrypted and reported.

[0128] Method 4

[0129] When the terminal device restores its RRC connection with the network-side device, it carries an encrypted RRM measurement status from the disconnected state in the RRC restoration completion message sent to the network-side device.

[0130] In this embodiment, when the terminal device performs RRC connection recovery to enter the RRC connected state from the RRC disconnected state, the terminal device can store the encryption requirements of the network-side device in the previous RRC connection, and report the RRM measurement status information of the disconnected state after encryption according to the encryption requirements in the RRC recovery completion message.

[0131] It should be noted that the RRM measurement status in the above-mentioned disconnected state can also be reported to the network-side device through other RRC messages, which will not be specifically limited here.

[0132] As an optional implementation, the terminal device obtains first configuration information, including:

[0133] The terminal device receives first configuration information sent by the network-side device in the target RRC state, wherein the target state is the RRC connection state in the first RRC state and the second RRC state;

[0134] Before the terminal device receives the first configuration information sent by the network-side device in the target RRC state, the method further includes:

[0135] The terminal device receives second configuration information from the network-side device, wherein the second configuration information is used to configure at least one of the following:

[0136] Activate the RRM measurement relaxation mode in the first RRC state;

[0137] The criteria for determining whether to activate the RRM measurement relaxation mode under the first RRC state;

[0138] The relevant judgment parameters used to determine whether the RRM measurement relaxation criteria are met in the first RRC state.

[0139] In practice, the terminal device can receive the first configuration information sent by the network side in the connected state, so as to determine whether to use the RRM measurement relaxation mode to relax RRM measurement when entering the second connected state.

[0140] Furthermore, the aforementioned judgment parameters used to determine whether the RRM measurement relaxation criteria are met can be understood as follows: the RRM measurement relaxation criteria can indicate which parameters the terminal device needs to measure, such as RSRP, RSRQ, etc., while the judgment parameters used to determine whether the RRM measurement relaxation criteria are met can be understood as including the threshold values ​​corresponding to each parameter in the RRM measurement relaxation criteria, for example: Figure 2a and Figure 2b S shown SearchThresholdP S SearchThresholdQ T SearchDeltaP S SearchDeltaP wait.

[0141] The second configuration information is similar to the first configuration information, except that the second configuration information is used for the terminal device to determine whether to enable the target RRM measurement mode in the first RRC state, while the first configuration information is used for the terminal device to determine whether to enable the RRM measurement relaxation mode in the second RRC state. This will not be elaborated further here.

[0142] It is worth noting that, assuming RRM measurement relaxation mode is enabled in the first RRC state, the network-side device can be configured to continue RRM measurement relaxation in the second RRC state. However, the RRM measurement relaxation scheme in the first RRC state can differ from that in the second RRC state. For example, assuming RRM measurement relaxation mode is enabled in both the RRC connected state and the RRC IDEL state, and both are relaxation modes, the measurement frequency in the IDEL state can be lower than the measurement frequency in the connected state. That is, the first configuration information and the second configuration information can configure different RRM measurement relaxation schemes (relaxation strategies).

[0143] Furthermore, the target RRM measurement mode includes an RRM measurement relaxation mode, and the criterion for activating the RRM measurement relaxation mode includes at least one of the following:

[0144] The terminal device's mobility is lower than a preset mobility, the terminal device is stationary, and the terminal device is not located at the edge of the serving cell.

[0145] In practice, the mobility of the aforementioned terminal devices is lower than the preset mobility, i.e., as shown below. Figure 2b The second judgment criterion shown; the aforementioned terminal device is not located at the edge of the serving cell, i.e., as shown in the figure. Figure 2a The first judgment criterion is shown; of course, if the terminal device is stationary, then the terminal device must meet the low mobility requirement, or, if the terminal device is not located at the edge of the serving cell, then if the terminal device is always stationary, then the terminal device must also meet the judgment criterion of not being located at the edge of the serving cell.

[0146] Example 1

[0147] To facilitate the explanation of the configuration process for RRM measurement relaxation when a terminal device transitions from an inactive state (RRC IDLE / Inactive) to an active state (RRC connected), as follows: Figure 4a Taking the illustrated embodiment as an example, the interaction process between the terminal device (hereinafter referred to as UE) and the network-side device (hereinafter referred to as NW) is explained in the following example:

[0148] Step 1. RRC IDLE: The UE receives the trigger conditions configured on the NW side.

[0149] In this step, the triggering condition can be configured through the second configuration information mentioned above, that is, the second configuration information is used to configure the triggering condition for enabling RRM measurement relaxation in IDLE state. The triggering condition may include at least one of the following: low mobility, not at the cell edge, stationary.

[0150] Step 2. When the UE enters the connected state, it reports its RRM measurement status in the IDLE state.

[0151] The aforementioned RRM measurement status may include at least one of the following: meeting low mobility, meeting stationary, meeting not at the cell edge, whether RRM measurement relaxation has been enabled, and the method of enabling RRM measurement relaxation.

[0152] In practical applications, the terminal device only needs to report the RRM measurement status in the IDLE state if the RRM measurement relaxation conditions in the IDLE state are met.

[0153] Specifically, the terminal device can report the RRM measurement status in the IDLE state using any of the following methods:

[0154] 1) In the RRC establishment completion message, the UE reports the information it needs to report; after the UE is securely activated, it encrypts and reports the RRM measurement status information based on the NW encryption requirements.

[0155] 2) In the RRC establishment completion message, the UE reports the RRM measurement status information (unencrypted);

[0156] 3) In the RRC recovery completion message, the UE reports the information it needs to report; and based on the NW encryption requirements, it encrypts and reports the RRM measurement status information.

[0157] 4) The UE reports the aforementioned status information (encrypted) in the RRC recovery completion message.

[0158] 5) The UE can report in other RRC messages.

[0159] Step 3. The UE receives the configuration information sent by the NW side and performs RRM measurement relaxation.

[0160] In this step, the above configuration information is the first configuration information, which can be used to configure the RRM measurement relaxation scheme that the terminal device needs to enable.

[0161] Additionally, it is worth noting that the UE can receive configuration information sent by the NW side and determine whether to perform RRM measurement relaxation-related reporting after entering the connected state based on the configuration information.

[0162] At this time, when the UE is configured to report RRM measurement relaxation-related information after entering the connected state, the UE can directly report the measurement results related to the RRM measurement relaxation criteria without evaluating the RRM measurement relaxation criteria, so that the network can determine whether to enable the RRM measurement relaxation mode.

[0163] As an optional implementation, the target RRM measurement mode includes an RRM measurement relaxation mode, and the first configuration information is used to configure the judgment criteria for the terminal device to enable the RRM measurement relaxation mode in the second RRC state.

[0164] The method further includes:

[0165] Before the terminal device enters the second RRC state from the first RRC state, it determines whether the judgment criteria for enabling the RRM measurement relaxation mode in the second RRC state are met.

[0166] When the terminal device determines that the judgment result is satisfied, it sends the RRM measurement status or RRM measurement related information to the network side device. The RRM measurement related information is used to indicate that the RRM measurement status meets the judgment criteria for enabling the RRM measurement relaxation mode under the second RRC state.

[0167] In practical implementation, before the terminal device transitions from the first RRC state to the second RRC state, it pre-obtains the criteria for enabling RRM measurement relaxation mode in the second RRC state and assesses whether the conditions for connected-state RRM measurement relaxation are met. Thus, after the terminal device enters the connected state, and if the conditions for connected-state RRM measurement relaxation are met, it can report RRM measurement-related information to the network-side device, indicating that the conditions for connected-state RRM measurement relaxation are satisfied. It should be noted that upon receiving the RRM measurement-related information reported by the terminal, the network-side device can configure the terminal device to enable RRM measurement relaxation mode in the second RRC state.

[0168] This saves time spent evaluating whether the connection state RRM measurement relaxation criteria are met from scratch after entering the connection state.

[0169] Example 2

[0170] To facilitate the explanation of another RRM measurement relaxation configuration process when a terminal device transitions from an inactive state (RRC IDLE / Inactive) to a connected state (RRC Connected), as follows: Figure 4b Taking the illustrated embodiment as an example, the interaction process between the terminal device (hereinafter referred to as UE) and the network-side device (hereinafter referred to as NW) is explained in the following example:

[0171] Step 1. The non-connected UE receives configuration information sent by the NW side.

[0172] In this step, the non-connected UE can receive configuration information broadcast by NW (i.e., the first configuration information), which contains the RRM measurement relaxation criteria in the connected state.

[0173] Optionally, the judgment threshold (or criterion) included in the RRM measurement relaxation criterion in the connected state may be the same as or different from the judgment threshold included in the RRM measurement relaxation criterion in the disconnected state.

[0174] In addition, the UE can determine whether the triggering conditions for relaxed connected-state RRM measurements are met based on the above configuration information.

[0175] Step 2. After the UE enters the connected state, it reports the RRM measurement status.

[0176] In this step, the aforementioned RRM measurement status can specifically be: meeting the triggering conditions for connection-mode RRM measurement relaxation. That is, the UE only reports the RRM measurement status when the triggering conditions for connection-mode RRM measurement relaxation are met.

[0177] Step 3. The UE receives the configuration information sent by the NW side and performs RRM measurement relaxation.

[0178] This step is similar to... Figure 4a Step 3 in the illustrated embodiment is the same and will not be repeated here.

[0179] As an optional implementation, the first RRC state is a connected state, and the second RRC state is a disconnected state. Before the terminal device performs RRM measurement in the second RRC state using the target RRM measurement mode, the method further includes:

[0180] When the terminal device leaves the connected state, it determines the target RRM measurement mode based on the first configuration information.

[0181] In specific implementation, the aforementioned first configuration information is received when the terminal device is in a connected state, and it is determined based on the first configuration information whether the terminal device should enable the RRM measurement relaxation mode when leaving the connected state to enter the non-connected state.

[0182] The aforementioned first configuration information can be sent to the terminal device in the connected state via an RRC message. For ease of explanation, the following embodiments use an RRC elease message carrying the first configuration information as an example, which does not constitute a specific limitation.

[0183] Optionally, the first configuration information is used to configure at least one of the following:

[0184] When the terminal device leaves the connected state, it enables the target RRM measurement mode;

[0185] The criteria for determining when the terminal device starts the target RRM measurement mode after leaving the connection state;

[0186] The serving cell list, wherein when the terminal device leaves the connected state, it enables the target RRM measurement mode for cells in the serving cell list;

[0187] The validity period of the first configuration information;

[0188] The measurement scheme corresponding to the target RRM measurement mode adopted by the terminal device when it leaves the connected state.

[0189] Assuming the target RRM measurement mode is RRM measurement relaxation mode, the terminal device can then perform the following procedure based on the specific details of the first configuration information:

[0190] Scenario 1

[0191] When the first configuration information configures the terminal device to enable RRM measurement relaxation mode when leaving the connection state, the terminal device enables RRM measurement relaxation mode according to the instruction of the RRRCRelease message when it receives the message.

[0192] Scenario 2

[0193] When the first configuration information configures the criteria for enabling the RRM measurement relaxation mode when the terminal device leaves the connection state, when the terminal device receives the RRRCRelease message, it evaluates whether the criteria for enabling the RRM measurement relaxation mode are met, and decides whether to enable the RRM measurement relaxation mode based on the evaluation result.

[0194] Scenario 3

[0195] When the first configuration information configures the serving cell list corresponding to enabling RRM measurement relaxation mode when the terminal device leaves the connected state, if the cell where the terminal device is stationed after leaving the connected state is included in the serving cell list, then the terminal device enables RRM measurement relaxation mode; otherwise, it enables normal RRM measurement mode.

[0196] Scenario 4

[0197] If the first configuration information has a specified validity period, the first configuration information can be discarded if that validity period is exceeded. The validity period of the first configuration information can be started from when the terminal device receives the aforementioned RRCRelease message or leaves the connection state.

[0198] Case 5

[0199] When the first configuration information configures the measurement scheme (e.g., R17 RRM relaxation method or R16 RRM relaxation method) corresponding to the RRM measurement relaxation mode adopted by the terminal device when leaving the connection state, the terminal device can use the corresponding measurement relaxation scheme to perform RRM measurement relaxation when it receives the above-mentioned RRRCRelease message.

[0200] Of course, the first configuration information can also be used to configure the judgment parameters related to RRM measurement relaxation of the serving cell. In this way, when the terminal device leaves the connected state, it is only necessary to determine the judgment parameters related to RRM measurement relaxation configured in the serving cell where the terminal device is camped, and the measurement results related to the RRM measurement relaxation criteria can be directly reported so that the network can determine whether to enable the RRM measurement relaxation mode.

[0201] It should be noted that in practical applications, the first configuration information can be configured with at least two of the above situations, and no specific limitation is made here.

[0202] Furthermore, when the terminal device leaves the connected state, it determines the target RRM measurement mode based on the first configuration information, including at least one of the following:

[0203] When the terminal device leaves the connected state, it determines to enable the target RRM measurement mode for the serving cell where it is stationed.

[0204] When the terminal device leaves the connected state and the serving cell list includes the serving cell where the terminal device is stationed, it determines to enable the target RRM measurement mode for the stationed serving cell.

[0205] When the terminal device leaves the connected state, and the serving cell where the terminal device is stationed is the same serving cell as the last serving cell of the terminal device in the connected state, the terminal device determines to enable the target RRM measurement mode for the stationed serving cell.

[0206] When a terminal device leaves the connected state, and the serving cell where the terminal device is currently stationed is the same serving cell as the last serving cell of the terminal device in the connected state, it is determined that the target RRM measurement mode should be enabled for the serving cell where the terminal device is currently stationed. Assuming that the terminal device enabled the RRM measurement mode in the connected state, if the serving cell where the terminal device is currently stationed after leaving the connected state is the same serving cell as the last serving cell of the terminal device in the connected state, the terminal device can continue to perform RRM measurement relaxation without having to re-evaluate the RRM measurement relaxation criteria.

[0207] Example 3

[0208] To facilitate the explanation of a configuration process for RRM measurement relaxation when a terminal device transitions from a connected state (RRC connected) to an inactive state (RRC IDLE / Inactive), as follows: Figure 4c Taking the illustrated embodiment as an example, the interaction process between the terminal device (hereinafter referred to as UE) and the network-side device (hereinafter referred to as NW) is explained in the following example:

[0209] Step 1. The UE receives the downlink RRC message sent by the NW.

[0210] In this step, the aforementioned RRC message is the message carrying the first configuration information. Specifically, this RRC message can be an RRC release message, and it can contain one or more of the following information:

[0211] 1) After the UE leaves the RRC connected state, RRM measurement relaxation is performed;

[0212] 2) The criteria upon which the UE performs RRM measurement relaxation after leaving the RRC connected state include one or more of the following:

[0213] i. Low mobility;

[0214] ii. stillness;

[0215] iii. Not located on the edge of the residential area;

[0216] 3) List of serving cells for UE to relax RRM measurement, i.e., which cells the UE selects to camp on after leaving the RRC connected state, and which cells can relax RRM measurement;

[0217] 4) The validity period of the first configuration information can be timed from when the UE receives the message or when it leaves the connected state;

[0218] 5) Types of RRM measurement relaxation methods: such as R17 RRM relaxation method or R16 RRM relaxation method.

[0219] Step 2. Based on the received message, the UE enables RRM measurement relaxation after leaving the connected state.

[0220] In this step, the UE can relax RRM measurements on the selected serving cell (the cell selected in IDLE or Inactive state) after leaving the connected state, based on the following principles:

[0221] i. Relaxation is only performed if the selected serving cell has configured a judgment threshold related to RRM measurement relaxation;

[0222] ii. Relaxation will only be applied if the selected service cell belongs to the above service cell list;

[0223] iii. Relaxation is only performed if the selected serving cell and the last serving cell in the connected state are the same cell.

[0224] As an optional implementation, when the terminal device transitions from the first RRC state to the second RRC state, it performs RRM measurement in the second RRC state according to the first configuration information, using the target RRM measurement mode, including:

[0225] The terminal device activates the RRM measurement relaxation mode in the first RRC state and performs a first conversion and a second conversion in sequence. The first conversion is from the first RRC state to the second RRC state, and the second conversion is from the second RRC state to the first RRC state.

[0226] If the terminal device determines that the first duration is less than the preset duration, and the serving cell of the terminal device has not changed during the first transition and the second transition, the terminal device shall activate the RRM measurement relaxation mode after the second transition, wherein the first duration is the duration during which the terminal device is in the second RRC state.

[0227] In specific implementation, the terminal device activates the RRM measurement relaxation mode in the first RRC state and performs the first and second transitions in sequence. The duration of the terminal device in the second RRC state is less than the preset duration. This can be understood as: after the terminal device briefly enters the second RRC state from the first RRC state, it returns to the first RRC state.

[0228] In practice, the preset duration can be configured according to actual needs; for example, existing timeframes can be reused. SearchDeltaP At this point, T can be enabled when entering the second RRC state. SearchDeltaP Specifically, the duration for which the terminal device remains in the second RRC state is less than a preset duration can be controlled by setting a timer. The length of this timer can reuse existing configuration parameters, such as the duration for mobility assessment in connected mode (T). SearchDeltaP ).

[0229] Of course, the above preset duration can also be equal to the value excluding T. SearchDeltaP Other durations besides the first duration can also be controlled in other ways, such as the above-mentioned preset duration being the duration set by the user according to actual business needs (e.g., set to 5 minutes, 3 minutes, 1 minute, etc.), without specific limitations here.

[0230] In this embodiment, if the terminal device briefly enters the second RRC state and then quickly returns to the first RRC state, and if the cell selected by the terminal device remains unchanged (i.e., no cell handover occurs in the connected state, and the terminal device reselects the previously used cell when entering the disconnected state), then the terminal device can continue to use the RRM measurement relaxation scheme before entering the second RRC state after returning to the first RRC state.

[0231] Example 4

[0232] To facilitate the explanation of the RRM measurement relaxation configuration process when a terminal device briefly enters a connected state (RRC connected) from an inactive state (RRC IDLE / Inactive) and then returns to an inactive state, as follows: Figure 4d Taking the illustrated embodiment as an example, the interaction process between the terminal device (hereinafter referred to as UE) and the network-side device (hereinafter referred to as NW) is explained in the following example:

[0233] Step 1. In IDLE state, the UE's serving cell is cell A, and at this time, the RRM measurement relaxation mode is triggered;

[0234] Step 2. The UE enters the connected state and starts the timer;

[0235] In this step, if a cell handover occurs in connected mode, the timer stops; otherwise, it continues until the timer's countdown reaches a preset duration (let's say T). SearchDeltaP The timer will only stop under certain conditions.

[0236] Step 3. The UE leaves the connected state. If the timer is still running, the UE assumes that the previously triggered RRM measurement relaxation has been triggered.

[0237] In this step, if the UE reselects to its previous cell (i.e., Cell A), the RRM measurement relaxation mode is enabled; otherwise, the normal RRM measurement mode is enabled.

[0238] In this embodiment, when the terminal device briefly enters the connected state from the non-connected state and then quickly returns to the non-connected state, when it re-enters the non-connected state, it can continue to use the RRM measurement relaxation mode under the non-connected state before entering the connected state to perform RRM measurement relaxation, without having to re-evaluate according to the RRM measurement relaxation criteria under the non-connected state when it re-enters the non-connected state.

[0239] As an optional implementation, when the terminal device transitions from the first RRC state to the second RRC state, it performs RRM measurement in the second RRC state according to the first configuration information, using the target RRM measurement mode, including:

[0240] The terminal device initiates an assessment related to the RRM measurement relaxation mode in the first RRC state, and performs a first transition before the assessment related to the RRM measurement relaxation mode is completed, wherein the first transition is from the first RRC state to the second RRC state.

[0241] In the second RRC state, the terminal device continues to perform the assessment related to the RRM measurement relaxation mode, wherein the target RRM measurement mode is determined based on the results of the assessment related to the RRM measurement relaxation mode.

[0242] In practice, there may be situations where the RRC status changes before the assessment related to the RRM measurement relaxation mode is completed. In such cases, related technologies would start the RRM measurement relaxation mode assessment from scratch after the RRC status change. However, in this embodiment, the previous RRM measurement relaxation mode assessment is continued after the RRC status change to reduce the additional measurements caused by the RRC status change during the RRM measurement relaxation mode assessment process.

[0243] For example, the RRM measurement relaxation criteria include the second judgment criterion mentioned above. Thus, before the low mobility assessment is completed (i.e., the assessment duration has not reached T), SearchDeltaP If the RRC status of the terminal device changes, the low mobility assessment can continue to be performed after the change, instead of starting the low mobility assessment from scratch after the change.

[0244] Additionally, after the terminal device continues to perform the assessment related to the RRM measurement relaxation mode while in the second RRC state, the following two situations may occur:

[0245] Scenario 1

[0246] If the second RRC state is a connected state, and the evaluation related to the RRM measurement relaxation mode is completed in the second RRC state, the terminal device can report the evaluation result to the network-side device in the connected state. Alternatively, if the evaluation result meets the RRM measurement relaxation criteria, the terminal device can report the evaluation result to the network-side device.

[0247] In this way, network-side devices can determine whether a terminal device has enabled RRM measurement relaxation mode based on the reports from the terminal device, and configure the terminal device accordingly.

[0248] Of course, if the second RRC state is a disconnected state, the terminal device can execute the corresponding RRM measurement mode according to the above evaluation results. For example, assuming that the network side device pre-configures the RRM measurement relaxation criteria for the terminal device in the disconnected state, and the terminal device completes the evaluation related to the RRM measurement relaxation mode in the disconnected state, and the evaluation result satisfies the RRM measurement relaxation criteria in the disconnected state, then the terminal device can trigger the RRM measurement relaxation mode in the disconnected state to execute the corresponding RRM measurement relaxation method.

[0249] Scenario 2

[0250] If the terminal device briefly enters the second RRC state and then returns to the first RRC state, the assessment related to the RRM measurement relaxation mode may not have been completed in the second RRC state. In this case, the assessment related to the RRM measurement relaxation mode can be continued after the terminal device returns to the first RRC state through the following method.

[0251] As an optional implementation, after the terminal device continues to perform the RRM measurement relaxation mode-related assessment in the second RRC state, the method further includes:

[0252] Before the assessment related to the relaxation mode of the RRM measurement is completed, the terminal device performs a second transition, wherein the second transition is from the second RRC state to the first RRC state;

[0253] The terminal device continues to perform the assessment related to the RRM measurement relaxation mode while in the first RRC state.

[0254] In specific implementation, when the first RRC state is in a disconnected state, when the terminal device obtains the evaluation result related to the RRM measurement relaxation mode, it can compare the pre-configured RRM measurement relaxation criteria of the terminal device in the disconnected state with the evaluation result. If the evaluation result satisfies the RRM measurement relaxation criteria in the disconnected state, the terminal device can trigger the RRM measurement relaxation mode in the disconnected state to execute the corresponding RRM measurement relaxation method.

[0255] Of course, the first RRC state mentioned above may also be a connected state. In this case, the terminal device can report the evaluation results related to the RRM measurement relaxation mode to the network side and determine whether to enable the RRM measurement relaxation mode according to the network side configuration.

[0256] Example 5

[0257] To facilitate the explanation of the RRM measurement process when a terminal device briefly enters a connected state (RRC connected) from an inactive state (RRC IDLE / Inactive) and then returns to an inactive state, as follows: Figure 4e Taking the illustrated embodiment as an example, the interaction process between the terminal device (hereinafter referred to as UE) and the network-side device (hereinafter referred to as NW) is explained in the following example:

[0258] Step 1. In IDLE state, the UE's serving cell is cell A, which receives the RRM measurement relaxation configuration sent by Cell A to begin the evaluation;

[0259] Step 2. Before the low mobility assessment is completed (assessment duration not reaching T) SearchDeltaP When the UE initiates an RRC connection establishment or recovery process, it enters the connected state.

[0260] Step 3. When the UE is in connected state, continue the previous IDLE state evaluation.

[0261] Following this step, the following two scenarios may be included:

[0262] 4.1 If the evaluation is completed while in connected state and the evaluation result indicates a low mobility state, the UE shall report the result.

[0263] 4.2 If the evaluation is completed only after the UE enters the idle / inactive state and the result is that it is in a low mobility state, then the UE triggers the RRM measurement relaxation method corresponding to the idle / inactive state.

[0264] Following scenario 1) above, the UE can perform the following: Figure 4a Step 3 shown in the diagram is similar to the steps described above and will not be repeated here.

[0265] In this implementation, when the terminal changes its RRC state before the RRM measurement relaxation mode-related assessment is completed, the RRM measurement relaxation mode-related assessment can be performed without interruption. When applied to application scenarios with frequent RRC state changes, this can greatly reduce the probability of re-performing the RRM measurement relaxation mode-related assessment, thereby reducing the duration of the RRM measurement relaxation mode-related assessment.

[0266] As another optional implementation, it is assumed that the first RRC state is a connected state and the second RRC state is a disconnected state;

[0267] If the terminal device determines that the first duration is less than a preset duration, and the serving cell of the terminal device has not changed during the first and second transitions, the terminal device activates the RRM measurement relaxation mode after the second transition, including:

[0268] Within a preset time period after the first conversion, the terminal device initiates an RRC connection recovery request to the serving cell where the terminal device is camped, in order to restore the connection state;

[0269] The terminal device receives RRM measurement relaxation configuration information from the serving cell and enables the RRM measurement relaxation mode based on the RRM measurement relaxation configuration information.

[0270] In specific implementation, the aforementioned non-connected state can refer to the RRC Inactive state. Given that in the Inactive state, the network-side device can save whether the RRM measurement relaxation mode was enabled in the RRC connected state before entering the Inactive state, if the terminal enables the RRM measurement relaxation mode in the connected state, and the terminal device immediately returns to the connected state after briefly entering the Inactive state, the network-side device can configure the terminal device to perform RRM measurement relaxation based on the RRC connection recovery request initiated by the terminal device.

[0271] Of course, the aforementioned non-connected state can also refer to the RRC IDEL state. In this case, given the IDEL state, the network side usually does not store whether the RRM measurement relaxation mode was enabled in the RRC connected state before entering the IDEL state. Therefore, before the terminal device receives the RRM measurement relaxation configuration information from the serving cell and enables the RRM measurement relaxation mode based on the RRM measurement relaxation configuration information, the terminal device needs to report to the network side device the RRM measurement status information corresponding to the RRM measurement relaxation mode being enabled in the connected state before entering the IDEL state.

[0272] Example 6

[0273] To facilitate the explanation of the RRM measurement relaxation configuration process when a terminal device briefly transitions from a connected state (RRC connected) to an inactive state (RRCInactive) and then returns to a connected state, as follows: Figure 4f Taking the illustrated embodiment as an example, the interaction process between the terminal device (hereinafter referred to as UE) and the network-side device (hereinafter referred to as NW) is explained in the following example:

[0274] Step 1. Cell A configures RRM measurement relaxation for the connected UE, then releases the UE to the inactive state and starts the timer;

[0275] Step 2. Before the timer expires, Cell A receives the connection restoration request initiated by the UE and restores the UE's connection;

[0278] Please see Figure 5 The execution entity of the RRM measurement configuration method provided in this application embodiment can be a network-side device, such as... Figure 5 As shown, the RRM measurement configuration method may include the following steps:

[0279] Step 501: The network-side device sends first configuration information to the terminal device; wherein, the first configuration information is used to configure the terminal device to perform RRM measurement in the second RRC state according to the first configuration information when it enters the second RRC state from the first RRC state.

[0280] This step is similar to... Figure 3 In the illustrated embodiment, the process of the terminal device acquiring the first configuration information corresponds to that of the first configuration information, the first RRC status, the second RRC status, and the target RRM measurement mode, respectively, as shown in the figure. Figure 3 The first configuration information, first RRC status, second RRC status, and target RRM measurement mode described in the method embodiment shown have the same meaning and will not be repeated here.

[0281] Optionally, the first configuration information is used to configure at least one of the following:

[0287] Optionally, the network-side device sends first configuration information to the terminal device, including:

[0288] The network-side device sends the first configuration information to the terminal device in the second RRC state;

[0289] Before the network-side device sends the first configuration information to the terminal device in the second RRC state, the method further includes:

[0290] The network-side device receives RRM measurement status or RRM measurement related information from the terminal device. The RRM measurement status refers to the measurement parameters when the terminal device is in the first RRC state. The RRM measurement related information is used to indicate that the RRM measurement status meets the judgment criteria for enabling the RRM measurement relaxation mode in the second RRC state.

[0291] The network-side device generates the first configuration information based on the RRM measurement status or RRM measurement-related information.

[0292] Optionally, the RRM measurement status includes at least one of the following:

[0293] Whether to enable RRM measurement relaxation mode in the first RRC state;

[0294] The measurement and relaxation scheme corresponding to the RRM measurement and relaxation mode used in the first RRC state;

[0295] The criteria for determining whether to enable RRM measurement relaxation mode under the first RRC state.

[0296] Optionally, before the network-side device receives the RRM measurement status or RRM measurement-related information from the terminal device, the method further includes:

[0297] The network-side device sends second configuration information to the terminal device, wherein the second configuration information is used to configure the terminal device to enable at least one of the following in the first RRC state:

[0298] The target RRM measurement mode;

[0299] The criteria for determining the target RRM measurement mode.

[0300] Optionally, the first RRC state is a connected state, and the second RRC state is a disconnected state;

[0301] The network-side device sends first configuration information to the terminal device, including:

[0302] When the network-side device is in a connected state with the terminal device, it sends first configuration information to the terminal device, wherein the first configuration information is used by the terminal device to determine the target RRM measurement mode when leaving the connected state.

[0303] Optionally, the first configuration information is used to configure at least one of the following:

[0304] When the terminal device leaves the connected state, it enables the target RRM measurement mode;

[0305] The criteria for determining when the terminal device starts the target RRM measurement mode after leaving the connection state;

[0306] The serving cell list, wherein when the terminal device leaves the connected state, it enables the target RRM measurement mode for cells in the serving cell list;

[0307] The validity period of the first configuration information;

[0308] The measurement scheme corresponding to the target RRM measurement mode adopted by the terminal device when it leaves the connected state.

[0309] Optionally, the first RRC state is a connected state, and the second RRC state is a disconnected state;

[0310] The method further includes:

[0311] The network-side device configures the terminal device to enable RRM measurement relaxation mode in the first RRC state;

[0312] The network-side device releases the RRC connection of the terminal device, and within a first time period after releasing the RRC connection of the terminal device, receives an RRC connection recovery request initiated by the terminal device;

[0313] When the network-side device determines that the first duration is less than the preset duration, it restores the RRC connection with the terminal device according to the RRC connection recovery request, and sends RRM measurement relaxation configuration information to the terminal device, wherein the RRM measurement relaxation configuration information is used to configure the terminal device to enable the RRM measurement relaxation mode.

[0314] In specific implementation, the aforementioned non-connected state can refer to the RRC Inactive state. Given that in the Inactive state, the network-side device can save whether the RRM measurement relaxation mode was enabled in the RRC connected state before entering the Inactive state, if the terminal enables the RRM measurement relaxation mode in the connected state, and the terminal device immediately returns to the connected state after briefly entering the Inactive state, the network-side device can configure the terminal device to perform RRM measurement relaxation based on the RRC connection recovery request initiated by the terminal device.

[0315] Of course, the aforementioned non-connected state can also refer to the RRC IDEL state. In this case, given the IDEL state, the network side usually does not store whether the RRM measurement relaxation mode was enabled in the RRC connected state before entering the IDEL state. Therefore, in the above steps: before the network-side device restores the RRC connection with the terminal device according to the RRC connection recovery request and sends the RRM measurement relaxation configuration information to the terminal device when it determines that the first duration is less than the preset duration, the network-side device obtains from the terminal device the RRM measurement status information corresponding to the terminal device enabling the RRM measurement relaxation mode in the connected state before entering the IDEL state.
