[0027] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0028] Figure 1 A block diagram of a communication system provided by an exemplary embodiment of the present disclosure is shown. The communication system may include: an access network 12 and a terminal device 14.

[0029] The access network 12 includes several network devices 120. The network device 120 can be a base station, which is a device deployed in the access network to provide wireless communication functions for terminal devices. The base station can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in the LTE system, it is called eNodeB or eNB; in the 5G NR system, it is called gNodeB or gNB. With the evolution of communication technology, the description of "base station" may change. For the convenience of description in the embodiments of the present disclosure, the above-mentioned devices that provide wireless communication functions for the terminal device 14 are collectively referred to as network devices. In the embodiments of the present disclosure, the network device may also be a positioning server.

[0030] The terminal device 14 can include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or Internet of Things (IoT) devices or Industry Internet of Things (IIoT) devices having wireless communication functions, or other processing devices connected to a wireless modem, and various forms of user equipment, Mobile Station (MS), terminal device, and the like. For the convenience of description, the above-mentioned devices are collectively referred to as terminal devices. The network device 120 and the terminal device 14 communicate with each other through a certain air interface technology, such as a Uu interface.

[0031] The technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Advanced long Term Evolution (LTE-A) system, New Radio (NR) system, evolved system of NR system, LTE-based access to Unlicensed spectrum (LTE-U) system, NR-U system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication system, or other communication systems, etc.

[0032] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication, but also support, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, and vehicle-to-everything (V2X) systems. The embodiments of the present disclosure can also be applied to these communication systems.

[0033] Before introducing the technical solution of the present disclosure, some background technical knowledge involved in the present disclosure is first introduced and explained.

[0034] In a communication system, a terminal device needs to periodically measure downlink signals to keep track of a network cell. RRM measurement is a measurement method for measuring downlink signals defined in communication standards.

[0035] Based on the definition in TS 38.133, conventional RRM measurement refers to: the terminal device performs measurements at a fixed measurement interval. In order to reduce the measurement power consumption caused by conventional RRM measurements, measurement relaxation is introduced. Measurement relaxation refers to an RRM measurement method that reduces the number of RRM measurements to achieve the purpose of reducing measurement power consumption. In related technologies, measurement relaxation generally refers to a measurement relaxation in the time domain, such as not performing measurements within a time period, or increasing the measurement interval to reduce the number of measurements, thereby reducing measurement power consumption.

[0036] 1) Measurement relaxation scheme for R15

[0037] The measurement rules for cell reselection defined in TS38.304 are as follows:

[0038] For same-frequency measurements:

[0039] If the serving cell satisfies S rxlev >S IntraSearchP and S qual >S IntraSearchQ , the terminal device can choose not to perform co-frequency measurement.

[0040] If the serving cell satisfies S rxlev ≤S IntraSearchP or S qual ≤S IntraSearchQ , the terminal equipment should perform co-frequency measurement.

[0041] For different frequency or system measurements:

[0042] If the serving cell satisfies S rxLev >S nonIntraSearchP , and S qual >S nonIntraSearchQ , the terminal device can choose not to perform measurements on NR inter-frequency or inter-system cells of the same priority or lower priority; the terminal device should measure NR inter-frequency or inter-system cells with higher priority for at least K*60s, where K is the number of inter-frequency and inter-system layers.

[0043] If the serving cell satisfies S rxlev ≤S nonIntraSearchP , and S qual ≤S nonIntraSearchQ , the terminal device should search and measure the inter-frequency layers with higher, equal or lower priority to prepare for possible reselection.

[0044] The basic idea is that when the terminal device performs the same frequency / different frequency measurement of the neighboring cell (same priority or lower priority), if the Reference Signal Receiving Power (RSRP) / Reference Signal Receiving Quality (RSRQ) of the serving cell is higher than the threshold (S IntraSearchP , S IntraSearchQ ), the same-frequency measurement may not be performed, or the same-frequency / inter-frequency measurement of the same level or lower may not be performed. For the high-priority inter-frequency measurement of the neighboring cell, if the RSRP / RSRQ of the serving cell is higher than the threshold (S IntraSearchP , S IntraSearchQ ), the measurement is relaxed to 60s.

[0045] 2) Measurement relaxation scheme for R16

[0046] The measurement relaxation scheme consists of two parts: one is determining the measurement relaxation criteria, which determines the criteria that a terminal must meet to enable measurement relaxation. These criteria are typically configured by the network to set certain measurement thresholds for the terminal, and the terminal determines whether relaxation can be performed based on these criteria and thresholds. The other is determining the specific relaxation criteria when different relaxation conditions are met, which are determined based on the measurement relaxation criteria provided by RAN4.

[0047] 2.1 Relaxation of rules

[0048] There are currently two relaxed rules: one is low mobility; the other is not at the cell edge.

[0049] 2.11 Low Mobility

[0050] Within a certain period of time (TSearchDeltaP ), if the difference between the reference received signal quality and the current RSRP of the terminal device is less than a preset threshold value (S SearchDeltaP ), which means that the signal change is not large, and it can be considered that the current state is stationary or low mobility. It is worth noting that this judgment only needs to be considered when the signal drops. The specific judgment conditions are as follows:

[0051] (S rxlevRef –S rxlev ) SearchDeltaP

[0052] Among them, S rxlev = S of the current serving cell rxlev , unit is dB; S rxlevRef = S of the current serving cell rxlev Reference value, in dB.

[0053] S rxlevRef Set it up as follows:

[0054] (1) The UE selects or reselects a new cell.

[0055] (2)(S rxlev -S rxlevRef >0).

[0056] (3) In T SearchDeltaP The judgment conditions were not met.

[0057] When any of the above conditions is met, the terminal device will S rxlevRef Set to the current serving cell's S rxlev .

[0058] About T SearchDeltaP Settings, LTE system settings T SearchDeltaP 5 minutes; NR is set to this value is configurable, and the current discussion is: T SearchDeltaP It should be set to be less than or equal to 5 minutes and should be a multiple of the measurement period. If eDRX is configured, if the eDRX period is greater than 5 minutes, then T SearchDeltaP Set to eDRX cycle.

[0059] In LTE, even if the relaxation conditions are met, the terminal device is required to perform measurements every 24 hours. In NR, R16 defines measurement relaxation or stopping of measurements (see the measurement relaxation criteria section below).

[0060] 2.12 Cell Edge

[0061] If the terminal device's current S rxlev Greater than the threshold S searchThresholdP And S​qual Greater than the threshold S searchThresholdQ (if configured), the terminal device is considered not to be at the cell edge. The specific judgment conditions are as follows:

[0062] S rxlev >S searchThresholdP , and S qual >S searchThresholdQ (If configured)

[0063] Among them, S rxlev = S of the current serving cell rxlev , unit is dB; S qual = S of the current serving cell qual , unit is dB.

[0064] It can be understood that these two thresholds are more relaxed than the thresholds for stopping measurement in R15, such as Figure 2 As shown, the definition of not being at the cell edge in R16 corresponds to Figure 1 The middle part area 210 in the.

[0065] 2.2 Measuring relaxation styles

[0066] In R16, measurement relaxation is generally implemented based on the time domain measurement relaxation method, such as: Method 1: Relax the measurement period defined in R15 to a wider time measurement interval.

[0067] Method 2: Stop measuring after 1 hour.

[0068] Method 3: During high-priority inter-frequency measurement, if the RSRP / RSRQ of the serving cell is higher than the threshold, the measurement is relaxed to K*60s.

[0069] It is understandable that no measurement relaxation is performed, that is, conventional RRM measurements are performed according to the definition in existing TS 38.133.

[0070] The final results of measuring relaxation in R16 are as follows:

[0071] On the basis of the original R15, for additional relaxation conditions, such as for non-central users of the same frequency / low priority level, if they are not at the edge of the cell or have low mobility, further relaxed measurements are performed, that is, criterion 1 is adopted to relax the measurement period defined in R15 to a wider time measurement interval.

[0072] The embodiments of the present disclosure do not exclude the introduction of new measurement relaxation methods in R17.

[0073] 3) Redcap users

[0074] The current 3GPP standardization has introduced a new terminal type called Reduced Capability UE (NR-lite or Redcap). Similar to IoT devices in LTE, these devices typically need to meet the following requirements: low cost and complexity, a certain degree of coverage enhancement, and power conservation.

[0075] With the introduction of Redcap users, unlike conventional Enhanced Mobile Broadband (eMBB) users, Redcap users are stationary in some scenarios, resulting in lower mobility than eMBB users. A common approach is to introduce new decision thresholds for Redcap users, using stricter mobility criteria to determine if a Redcap user is stationary.

[0076] The measurement relaxation mechanism of R16 needs to be enhanced to accommodate Redcap users. The widely discussed approach is to introduce stricter judgments for low mobility, which is likely to be for (S rxlevRef –S rxlev ) SearchDeltaP , set a smaller S SearchDeltaP , using the smaller S SearchDeltaP To determine whether the Redcap user is in a state of inactivity.

[0077] Current possible temporal relaxation methods may include:

[0078] Time domain relaxation method 1: that is, not measuring for a longer period of time based on the original measurement stop (1 hour).

[0079] As an implementation example: stop measuring for X hours, X>=1.

[0080] Time domain relaxation method 2: based on the original measurement, the measurement interval is increased.

[0081] As an implementation example, a longer measurement interval is used for relaxation measurement (scaling factor '), wherein the scaling factor ' is a scaling factor larger than the original scaling factor. The scaling factor used in the existing protocol is K1, that is, a scaling factor larger than K1 is introduced.

[0082] 4) Network Slicing

[0083] ​Network slicing can provide a complete end-to-end virtual network for specific users. By dividing network resources into multiple network slices, 5G network slicing can provide differentiated services to users with different service requirements (such as latency, reliability, capacity, isolation, and other functions). Carrier networks will not only serve information consumption services characterized by "best effort" transmission, but also meet the communication requirements of production control services characterized by "deterministic transmission", allocating logically or physically isolated network resources to services with very different communication requirements.

[0084] A network slice consists of the Radio Access Network (RAN) and the Core Network (CN). Network slicing relies on the principle that traffic from different slices is handled by different Protocol Data Unit (PDU) sessions. The network can implement different network slices by scheduling and providing different Layer 1 / Layer 2 configurations.

[0085] Each network slice is uniquely identified by Single-Network Slice Selection Assistance Information (S-NSSAI), which consists of a slice service type (Slice / ServiceType, SST) and a slice differentiator (Slice Differentiator, SD). NSSAI is a collection of S-NSSAIs, including one or more S-NSSAIs.

[0086] Redcap users generally have positioning needs. As mentioned above, if the terminal device is a Redcap user, when using the enhanced positioning technology based on cell identification (Enhanced Cell-ID, E-CID) positioning method, it is necessary to measure the RSRP of the local area and neighboring cells. However, Redcap users are currently considering relaxing the measurement of neighboring cells. For example, for Redcap users who are at the edge of the cell and stationary, there is no need to measure the neighboring cells in the idle state. At this time, the Redcap user does not have the measurement results of the neighboring cells, and it is impossible to effectively locate the Redcap user based on the measurement results.

[0087] When the measurement is relaxed, the measurement interval may also be extended. When the measurement interval is large, the position of the terminal device may change significantly within the measurement interval. If the terminal device has positioning requirements, it needs to be positioned based on the measurement results corresponding to the larger measurement interval, which will lead to inaccurate positioning results.

[0088] If the terminal device uses network slicing, when the network slice changes, the frequency priority of the terminal device will change. In this case, measurement relaxation will be performed according to the frequency priority corresponding to the previous network slice, and the measurement relaxation method is inaccurate.

[0089] In the embodiment of the present disclosure, the terminal device does not perform measurement relaxation in the non-connected state, thereby avoiding the above-mentioned problem. This is exemplarily described below in conjunction with the following embodiment.

[0090] Figure 3 A flowchart of a relaxation measurement method provided by an exemplary embodiment of the present disclosure is shown, which can be applied to Figure 1 In the communication system shown in FIG. , the method may include:

[0091] Step 310: The terminal device does not perform measurement relaxation in the non-connected state.

[0092] The non-connected state refers to a radio resource control (RRC) state of a terminal device. The non-connected state includes at least one of the following states: an idle state (IDLE) and an inactive state (INACTIVE).

[0093] In the disclosed embodiments, a terminal device does not perform measurement relaxation in a non-connected state. For example, a terminal device does not perform measurement relaxation in an idle state; nor does a terminal device perform measurement relaxation in an inactive state. In the disclosed embodiments, the terminal device may be of all types or of some types, such as a terminal device with a specific requirement, a terminal device using a specific service, a terminal device belonging to a specific user type, and so on.

[0094] Measurement relaxation refers to an RRM measurement method that reduces the number of measurements compared to conventional RRM measurements defined in TS 38.133. Measurement relaxation helps save energy consumption in terminal devices.

[0095] The terminal device performs measurement relaxation according to certain measurement relaxation criteria. Optionally, the terminal device does not perform measurement relaxation in the non-connected state, which may mean not executing all measurement relaxation criteria and performing regular RRM measurements; or not executing some measurement relaxation criteria.

[0096] In summary, with the method provided in this embodiment, the terminal device may not perform measurement relaxation in the non-connected state, thereby avoiding the problem that specific needs cannot be guaranteed due to measurement relaxation in the current scenario.

[0097] In the exemplary embodiment, the terminal device may be implemented in the following manner:

[0098] Terminal devices are terminal devices with positioning requirements.

[0099] It is understandable that if a terminal device is a terminal device with positioning requirements, the terminal device requires as many measurement results as possible in each cell to ensure that the positioning result obtained based on the measurement results meets the positioning requirements. Not relaxing measurements for terminal devices with positioning requirements can ensure that the positioning requirements are met.

[0100] Terminal devices are terminal devices that use network slicing services.

[0101] Network slicing is related to the frequency of terminal devices, and terminal devices need to perform measurement relaxation based on frequency priority.

[0102] It is understandable that if the terminal device is a terminal device using a network slicing service, when the network slice changes, the frequency priority of the terminal device will change accordingly. Then, if measurement relaxation is performed according to the frequency priority corresponding to the previous network slice, the measurement relaxation method performed by the terminal device will not be the correct measurement relaxation method. Not performing measurement relaxation on terminal devices using network slicing services can avoid the problem that the measurement relaxation method currently performed by the terminal device is not the correct measurement relaxation method.

[0103] The terminal device is a terminal device belonging to the limited capability terminal type.

[0104] The terminal device of the limited capability terminal type is the Redcap user introduced above. Exemplarily, the terminal device of the limited capability terminal type includes: industrial sensors, positioning sensors, and video surveillance equipment.

[0105] It is understandable that since the restricted capability terminal type is considering relaxing neighboring cell measurements, when this type of terminal device has positioning requirements, relaxing neighboring cell measurements will result in the inability to obtain neighboring cell measurement results, resulting in the inability to meet positioning requirements. Not relaxing measurements for restricted capability terminal devices can avoid the problem of terminal devices' positioning requirements being unmet due to relaxed measurements.

[0106] In an exemplary embodiment, the terminal device performs measurement relaxation based on a measurement relaxation criterion.

[0107] In a possible implementation, step 310 is alternatively implemented as follows: the terminal device does not perform measurement relaxation based on the first criterion in the non-connected state.

[0108] The first criterion is agreed upon in the communication protocol and is executed by the terminal device in order to perform measurement relaxation.

[0109] Optionally, the first criterion includes at least one of the following: time domain measurement relaxation criterion; frequency domain measurement relaxation criterion; spatial domain measurement relaxation criterion.

[0110] Exemplarily, the relaxation criteria for time domain measurement include: increasing the measurement interval, or stopping measurement for a period of time.

[0111] Exemplarily, the frequency domain measurement relaxation criteria include: reducing measurements on certain frequency points and cells.

[0112] Exemplarily, the spatial measurement relaxation criterion includes: reducing measurements on certain beams.

[0113] In the embodiment of the present disclosure, the first criterion may be a part of the measurement relaxation criteria, or may be all of the measurement relaxation criteria.

[0114] That is, the terminal device may not execute only a part of the measurement relaxation criteria in the non-connected state, while continuing to execute another part of the measurement relaxation criteria; the terminal device may also not execute all the measurement relaxation criteria.

[0115] Exemplarily, the terminal device is a terminal device with positioning requirements, but the positioning requirements are not high, and the first measurement relaxation criterion only includes: stopping measurement for a period of time, which is a time domain measurement relaxation criterion.

[0116] Exemplarily, the terminal device is a terminal device with a positioning requirement, and the positioning requirement is high, then the first measurement relaxation criterion includes all measurement relaxation criteria.

[0117] To sum up, the method provided in this embodiment allows the terminal device to choose not to execute some measurement relaxation criteria, or choose not to execute all measurement relaxation criteria. This is beneficial for the terminal device to relax measurements based on the supported measurement relaxation criteria in some scenarios while ensuring specific needs, thereby achieving the effect of saving energy consumption.

[0118] In an exemplary embodiment, the terminal device is instructed not to perform measurement relaxation in a non-connected state through explicit instructions from the network side and / or communication protocol agreement.

[0119] In a possible implementation, the network side instructs the terminal device, in conjunction with reference Figure 4 It is understandable that this implementation method may correspond to a scenario where the positioning requirement is initiated by the network side.

[0120] Figure 4 A flowchart of a relaxation measurement method provided by an exemplary embodiment of the present disclosure is shown, which can be applied to Figure 1 In the communication system shown in FIG. , the method may include:

[0121] Step 410: The network device sends an indication message to the terminal device.

[0122] The terminal device is one of the following: a terminal device with positioning requirements; a terminal device using network slicing services; or a terminal device of a limited capability terminal type. For details, please refer to the above embodiments and will not be repeated here.

[0123] Optionally, the network device is a base station; step 410 is replaced by: the base station receives a positioning notification message sent by the positioning server, the positioning notification message is used to notify the positioning server that there is a need to locate the terminal device; the base station sends an indication message to the terminal device based on the positioning notification message.

[0124] That is, the positioning server sends a positioning notification message to the base station to notify the base station of the presence of positioning requirements. Based on the positioning notification message, the base station instructs the terminal device in an indication message not to perform measurement relaxation in the non-connected state. The positioning notification message can be transferred from the anchor base station to the non-anchor base station.

[0125] The indication message is carried in a system message or a dedicated signaling. The dedicated signaling is the signaling used for unicast communication between the network device and the terminal device.

[0126] Exemplarily, the dedicated signaling is an RRC connection release message, and the RRC connection release message is used to instruct the terminal device to enter an idle state or an inactive state.

[0127] Optionally, the network device is a positioning server, and step 410 is replaced by: the positioning server sends an indication message to the terminal device.

[0128] That is, the positioning server sends an instruction message to the terminal device, instructing the terminal device not to perform measurement relaxation in the non-connected state.

[0129] Exemplarily, the positioning server sends the indication message to the base station, which forwards the indication message to the base station. It is understandable that the base station only transparently processes the indication message and does not identify the content of the indication message.

[0130] Step 420: The terminal device receives the indication message.

[0131] As described in step 410 above, the terminal device may receive an indication message from a base station or from a positioning server.

[0132] Step 430: The terminal device does not perform measurement relaxation in the non-connected state based on the indication message.

[0133] Optionally, the terminal device does not perform measurement relaxation in a non-connected state based on the indication of the network device in the indication message.

[0134] In another possible implementation, the communication protocol stipulates the behavior of the terminal device, that is, based on the stipulated rules in the communication protocol, the terminal device does not perform measurement relaxation in the non-connected state.

[0135] It is understandable that the above two implementations can be implemented in combination. That is, the terminal device does not perform measurement relaxation in the non-connected state based on the indication message and the agreed rules in the communication protocol.

[0136] Optionally, a restriction condition may be added to not performing measurement relaxation in the non-connected state. That is, the terminal device does not perform measurement relaxation in the non-connected state within the scope of the restriction condition.

[0137] The restriction condition includes at least one of the following conditions: a restriction condition carried in the instruction information; a restriction condition agreed upon in the communication protocol. That is, the restriction condition can be added to the instruction information sent by the network device to the terminal device, and the restriction condition can also be added to the agreed rules in the communication protocol.

[0138] Optionally, the type of restriction includes: the terminal device does not perform measurement relaxation within a target time period, or the terminal device does not perform measurement relaxation within a target area. When the restriction is a restriction carried in the indication information, the target time period or target area can be understood as being indicated by the network device through a system message or dedicated signaling; when the restriction is a restriction agreed upon in a communication protocol, the target time period or target area can be understood as being agreed upon in the communication protocol.

[0139] The target geographical area may be a Tracking Area (TA) or a Radio Access Network Notification Area (RNA).

[0140] Exemplarily, the positioning server instructs the terminal device not to perform measurement relaxation within the target time range T because there is a current need to locate the terminal device. Exemplarily, the base station instructs the terminal device not to perform measurement relaxation within certain cells of the base station. Exemplarily, based on agreed rules in the communication protocol, the terminal device does not perform measurement relaxation within the target time range T. Exemplarily, based on agreed rules in the communication protocol, the terminal device does not perform measurement relaxation within certain cells.

[0141] To sum up, the method provided in this embodiment allows the terminal device to not perform measurement relaxation in a non-connected state through network-side display instructions or communication protocol agreements, thereby avoiding the problem of unmet needs caused by measurement relaxation in the current scenario.

[0142] Meanwhile, the method provided in the embodiment can indicate the terminal device not to relax the measurement in the non-connected state by the positioning server or by the base station, thereby improving the flexibility of indicating the terminal device.

[0143] Meanwhile, the method provided in the embodiment can additionally limit the condition of not relaxing the measurement in the non-connected state, and the terminal device can not relax the measurement in the non-connected state based on the additional time limit condition or the regional limit condition, thereby avoiding the problem that the specific demand cannot be guaranteed due to the measurement relaxation in a certain time range or a certain region.

[0144] In the illustrative embodiment, the protocol layer of the terminal device includes a non-access layer and an access layer, and the non-access layer gives the access layer a high-layer indication to inform that the measurement is not relaxed in the non-connected state.

[0145] In a possible implementation, the step 310 is replaced by: the non-access layer delivers a high-layer indication to the access layer; and the access layer does not relax the measurement in the non-connected state based on the high-layer indication.

[0146] It can be understood that the implementation can correspond to a scenario in which the terminal device initiates a positioning demand, or a scenario in which the related information of the network slice used by the terminal device changes.

[0147] Optionally, the high-layer indication includes a first high-layer indication, and the first high-layer indication is used to indicate that the measurement is not relaxed in the non-connected state. The first high-layer indication can be understood as a display indication, that is, the non-access layer directly indicates the access layer not to relax the measurement in the non-connected state.

[0148] Optionally, the high-layer indication includes a second high-layer indication, and the second high-layer indication is used to indicate trigger cause information, and the trigger cause information is used to inform the reason for triggering the terminal device not to relax the measurement in the non-connected state. The second high-layer indication can be understood as an implicit indication, that is, the non-access layer indicates the trigger cause information to the access layer, and the access layer determines not to relax the measurement in the non-connected state based on the trigger cause information.

[0149] The trigger cause information can be one of the following implementation modes:

[0150] The trigger cause information includes: a positioning demand notification, and the positioning demand notification is used to inform that the terminal device has a positioning demand.

[0151] That is, the non-access layer informs the access layer that the terminal device has a positioning demand, and the access layer determines not to relax the measurement in the non-connected state.

[0152] The triggering reason information includes: network slice information change notification, which is used to notify the terminal device that there is a change in the relevant information of the network slice.

[0153] That is, the non-access layer informs the access layer that there is a change in the relevant information of the network slice of the terminal device, and the access layer decides not to perform measurement relaxation in the non-connected state.

[0154] Exemplarily, the relevant information of the network slice of the terminal device includes at least one of the following information: S-NSSAI, SST, slice group, slice ID, slice group ID, operator-defined access category corresponding to the slice, and slice-related frequency information.

[0155] The triggering cause information includes: network slice information, which is used to notify the current terminal device of the relevant information of the network slice.

[0156] For example, the non-access layer informs the access layer of relevant information about the network slice of the terminal device. When the access layer determines that the network slice information of the terminal device has changed based on the network slice information, the access layer decides not to perform measurement relaxation in the non-connected state.

[0157] For example, the non-access layer informs the access layer terminal device of the relevant information of the network slice. When the access layer determines that the frequency priority has changed based on the network slice information, the access layer decides not to perform measurement relaxation in the non-connected state.

[0158] Exemplarily, the relevant information of the network slice of the terminal device includes at least one of the following information: S-NSSAI, SST, slice group, slice ID, slice group ID, operator-defined access category corresponding to the slice, and slice-related frequency information.

[0159] To sum up, the method provided in this embodiment transmits high-layer instructions to the access layer through the non-access layer, and the terminal device can not relax the measurement in the non-connected state based on the high-layer instructions, thereby avoiding the problem of specific needs not being guaranteed due to measurement relaxation in the current scenario.

[0160] In an exemplary embodiment, the protocol layers of the terminal device include an access layer and a non-access layer. When not performing measurement relaxation in a non-connected state, there are several possible implementations:

[0161] The access layer does not perform the measurement relaxation in the upcoming non-connected state.

[0162] Exemplarily, the terminal device is a terminal device with positioning requirements, and the access layer does not enter the measurement relaxation in the upcoming connected state.

[0163] The access layer stops the current measurement relaxation in the connected state.

[0164] Exemplarily, the terminal device is a terminal device with positioning requirements, and the access layer stops the current measurement relaxation in the connected state and falls back to the original regular RRM measurement mode for measurement.

[0165] The access layer stops the current measurement relaxation in the connected state and enters the next measurement relaxation evaluation period based on the parameters provided by the non-access layer.

[0166] Exemplarily, the terminal device is a terminal device using network slice services, and the access layer stops the current measurement relaxation in the connected state and updates according to the parameters provided by the non-access layer to perform the next round of measurement relaxation evaluation.

[0167] It can be understood that for the scenario of the terminal device being a terminal device using network slice services, the access layer can also continue the current measurement relaxation in the connected state, and after ending the current measurement relaxation evaluation period, enter the next measurement relaxation evaluation period based on the parameters provided by the non-access layer.

[0168] It should be noted that the above method embodiments can be implemented individually or in combination, and the present disclosure does not limit this.

[0169] In the above various embodiments, the steps performed by the terminal device can be implemented individually as a measurement relaxation method on the terminal device side, and the steps performed by the network device can be implemented individually as a measurement relaxation method on the network device side.
