[0025] The embodiments of the present application will be described below with reference to the drawings.

[0026] Please refer to Figure 1 , Figure 1 is a schematic diagram of a communication system provided by an embodiment of the present application. As shown in Figure 1 , the communication system includes a plurality of network devices 110 and terminal devices 120. The plurality of network devices 110 can be deployed in a radio access network (RAN) 10, and the number of terminal devices 120 is usually multiple. One or more terminal devices 120 can be distributed in a cell managed by each network device 110. In the embodiments of the present application, when the terminal device 120 enters the coverage of the system, the terminal device 120 performs a cell search process, and the terminal device 120 searches for a cell that meets the requirements in the coverage of one or more network devices 110.

[0027] The network device 110 and the terminal device 120 can communicate with each other through air interface technology, for example, can communicate with each other through cellular technology. The schemes described in the embodiments of the present application can be applied to a system of 5G mobile communication technology, an evolved long term evolution (eLTE) system, a communication system of multiple communication technologies fusion (for example, a communication system of LTE technology and NR technology fusion), or a subsequent evolved communication system.

In order to represent the connection relationship between the devices conveniently and intuitively, Figure 2The communication link between the network device 110 and the terminal device 120 can include: a downlink (DL) transmission from the network device 110 to the terminal device 120, and / or an uplink (UL) transmission from the terminal device 120 to the network device 110.

The terminal device can also be a handheld device with wireless communication function, a vehicle-mounted device, a wearable device, a network device, or other processing device connected to a wireless modem, a terminal device in a future 5G network, or a terminal device in a future evolved public land mobile network (PLMN), and the like.

[0030] The network device 110 in the RAN related to the embodiments of the present application can be a base station (Base Station, BS), which is a device deployed in the RAN to provide wireless communication functions for terminals. The base station can include various forms of macro base stations, micro base stations, relay stations, access points, and the like.

The network device in the embodiments of the present application also includes devices providing base station functions in future new communication systems, etc. With the evolution of communication technology, the name "base station" may change. For convenience of description, in the embodiments of the present application, the above-mentioned devices providing wireless communication functions for terminal devices 120 are collectively referred to as network devices.

[0031] It should be noted that, Figure 2 The forms and quantities of the network device 110 and the terminal device 120 shown in the above are only used for example and do not constitute a limitation on the embodiments of the present application.

[0032] For a terminal device in an idle state or an inactive state, in order to meet the mobility requirement, the terminal device needs to perform neighbor cell measurement to measure neighbor cells on different frequencies or on different RATs, including intra-frequency cells, inter-frequency cells and inter-system cells. The system message of the serving cell in which the terminal device resides usually broadcasts neighbor cell configurations of multiple frequencies, and different frequencies have different frequency priorities. The terminal device needs to measure neighbor cells on frequencies with higher priorities than the frequency in which it resides. Once the cell on the high-priority frequency meets the reselection condition, i.e., the number of cells on the high-priority frequency exceeds a threshold Thresh X,HighQ or Thresh X,HighPWhen the terminal device needs to reselect to a cell on a high priority frequency, the terminal device needs to measure neighbor cells on the same priority frequency as the current camped frequency when the signal quality of the serving cell is below a certain threshold. Then the terminal device ranks the measured cells according to the signal quality, and the terminal device needs to reselect to the cell with the highest ranking. For the frequencies with lower priority than the current camped frequency, the terminal device only needs to measure the neighbor cells on these frequencies when the signal quality of the serving cell is poor (e.g., below a certain threshold SnonIntraSearchP). When the signal quality of the serving cell is below a threshold such as Thresh Serving,LowQ , and the signal quality of a neighbor cell on a low priority frequency is above a threshold such as Thresh X,LowQ , the terminal device can reselect to a cell on the low priority frequency.

[0033] If the measurement is more frequent, it is more power consuming for the terminal device. Therefore, the mechanism of relaxed measurement is introduced in the 5G communication protocol. The relaxed measurement can make the terminal device reduce the frequency points that need to be measured, reduce the measurement time, and prolong the measurement period of periodic measurement. For the terminal device in the 5G communication system, if it is determined that the terminal device is low-speed mobile or not at the cell edge, the relaxed measurement can be triggered. The terminal device needs to determine whether it can relax the radio resource management (RRM) measurement, and the specific standard is set by the system information block 2 (SIB2).

[0034] The SIB2 can provide the configuration of relaxed measurement, including the judgment criteria of low mobility, the judgment criteria of being at the cell edge, the standard of relaxed measurement, and whether the measurement of the high priority frequency can be relaxed. When the terminal device determines that the standard of relaxed measurement is met, the terminal device can relax the measurement of the same frequency, the same frequency priority inter-frequency, the lower frequency priority inter-frequency, and the lower frequency priority inter-system neighbor cell. When the SIB2 indicates that the measurement of the high priority frequency can be relaxed (highPriorityMeasRelax), the terminal device can relax the measurement of the high frequency priority inter-frequency and inter-system neighbor cell after determining that the standard of relaxed measurement is met. If the highPriorityMeasRelax is not configured, but the terminal device finds that the low mobility and not at the cell edge are met at the same time, the inter-frequency (including the high priority frequency point) and inter-system relaxed measurement can be relaxed. The standard of relaxed measurement is based on the signal quality of the cell, not the signal quality of the beam.

[0035] wherein the criterion for judging low mobility is based on the delta value of the RSRP of the serving cell, specifically: (Srxlev ref -Srxlev)<S SearchDeltaP wherein Srxlev is the current Srxlev value of the serving cell. Srxlev ref is the reference Srxlev value of the serving cell, and the method for obtaining it is: after selecting or reselecting a cell, or (Srxlev-Srxlev ref )>0, or when the T SearchDeltaP has not reached the relaxed measurement criterion, the reference Srxlev value is set equal to the current Srxlev value of the serving cell.

[0036] wherein the criterion for judging not at the cell edge is based on the cell signal quality RSRP and / or RSRQ, specifically: Srxlev>S SearchThresholdP , and S SearchThresholdQ is configured, and Squal>S SearchThresholdQ , wherein Srxlev and Squal are the current measurement values of the serving cell.

[0037] 1) If SIB2 configures the low mobility evaluation criterion (lowMobilityEvaluation) but does not configure the criterion for not being at the cell edge, and the terminal device performs at least T SearchDeltaP measurements on intra-frequency, NR inter-frequency and inter-system frequencies after selecting (reselecting) a cell, and the low mobility evaluation criterion has been met for T SearchDeltaP , the terminal device can relax the measurement on the intra-frequency. If the serving cell meets Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, for any one high priority NR inter-frequency or inter-system frequency, within 1 hour after the last cell reselection measurement on the corresponding frequency, and the high priority measurement relaxation (highPriorityMeasRelax) is set to True, the terminal device can not measure on the frequency. If the serving cell meets Srxlev≤SnonIntraSearchP or Squal≤SnonIntraSearchQ, the terminal device can relax the measurement on the NR inter-frequency, inter-system frequency.

[0038] 2) If the terminal device meets the criteria of not being at the cell edge, but the low mobility criteria is not configured, and the terminal device meets the criteria of not being at the cell edge, the terminal device can relax the measurement for the intra-frequency. If the serving cell meets SrxlevSnonIntraSearchP or SqualSnonIntraSearchQ, the terminal device can relax the measurement for the NR inter-frequency, inter-RAT frequency.

[0039] 3) If the terminal device meets the criteria of not being at the cell edge and the low mobility criteria after the terminal device performs the measurement for the intra-frequency, NR inter-frequency or inter-RAT for at least T SearchDeltaP measCellReselection or T SearchDeltaP measEUTRAReselection, and the terminal device meets the criteria of not being at the cell edge, the terminal device can not perform the measurement for any of the intra-frequency, NR inter-frequency, or inter-RAT frequency within 1 hour since the last time the terminal device performs the measurement for the corresponding frequency due to the cell reselection; otherwise, if the terminal device meets the criteria of not being at the cell edge and the low mobility criteria after the terminal device performs the measurement for the intra-frequency, NR inter-frequency or inter-RAT for at least T SearchDeltaP measCellReselection or T SearchDeltaP measEUTRAReselection, or the terminal device meets the criteria of not being at the cell edge and the combineRelaxedMeasCondition is not configured, the terminal device can relax the measurement for the intra-frequency, the same or low priority NR inter-frequency or inter-RAT frequency. If the serving cell meets SrxlevSnonIntraSearchP or SqualSnonIntraSearchQ, the terminal device can relax the measurement for the high priority NR inter-frequency or inter-RAT frequency.

[0040] In the current technology, after the terminal device discovers that the relaxed measurement criteria is met, the terminal device can take the relaxed measurement or not measure the neighbor cell for the intra-frequency, inter-frequency or inter-RAT. However, when there is a neighbor cell supporting the user demand service in the intra-frequency, inter-frequency or inter-RAT, if the relaxed measurement mechanism is applied, the terminal device cannot quickly detect the cell supporting the user demand service, which affects the latency of the terminal device to establish the corresponding service such as a certain slice service, thereby affecting the user experience.

[0041] To solve the above problems, the application provides a neighbor cell measurement method, which determines the measurement mode for the neighbor cell supporting the target service according to the configured relaxed measurement criteria, can perform the priority measurement for the neighbor cell supporting the target service, and further enables the terminal device to preferentially reselect the cell supporting the target service, thereby meeting the service demand of the terminal device.

[0042] In the following, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application, so that those skilled in the art can better understand the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0043] Please refer to Figure 2 , Figure 2 A flowchart of a neighbor cell measurement method provided by the embodiments of the present application is applied to a communication system as shown in Figure 1 The method includes the following steps as shown in Figure 2

[0044] S210, the terminal device receives a first message from a serving cell, and the first message is used to configure a relaxed measurement criterion.

[0045] The relaxed measurement criterion includes at least one of the following: a low mobility judgment criterion, a judgment criterion of not being at a cell edge, and a stationary state judgment criterion.

[0046] Specifically, the first message can be an SIB2 message, and the serving cell where the terminal device is located can provide the configuration of relaxed measurement through the SIB2 message, including the judgment criterion of low mobility, the judgment criterion of being at a cell edge, the stationary state judgment criterion, the criterion of relaxed measurement, and whether the measurement of high priority frequency can be relaxed. When the terminal device determines that the criterion of relaxed measurement is met, the terminal device can determine the measurement manner of the same frequency, different frequency, or different system neighbor cell.

[0047] S220, the terminal device performs measurement on a first frequency point corresponding to a first cell according to the first message, and the first cell is a neighbor cell supporting a target service.

[0048] When the terminal device meets the relaxed measurement criterion and the neighbor cell performing relaxed measurement can provide the terminal device with access to the target service, in order to enable the terminal device to access the cell supporting the target service as much as possible, the embodiments of the present application re-determine the measurement manner of the neighbor cell supporting the target service when the terminal device meets the relaxed measurement criterion, so that the neighbor cell supporting the target service can be measured preferentially, and then the terminal device can be preferentially reselected to the cell supporting the target service, thereby meeting the service demand of the terminal device.

[0049] ​In the embodiments of the present application, the target service can be an intended slice, that is, a slice corresponding to a service type, and the terminal device expects to establish a service of the service type in the future, such as a high-definition voice service, a high-definition video service, a low-latency service, a low-latency high-reliability service, and the like.

[0050] In an example, the first cell can also be a cell to which the terminal device expects to access to support a multicast service or a closed-mode cell belonging to a member. When the terminal device needs to preferentially access these cells, if the terminal device currently satisfies the relaxed measurement criterion, the terminal device can perform measurement on the cell supporting the multicast service or the closed-mode cell belonging to the member by using the method described above, so as to camp on these cells as soon as possible.

[0051] It should be noted that the first cell can also be a cell to which the terminal device expects to access in other application scenarios or a cell supporting other expected services, and the embodiments of the present application do not limit this.

[0052] In a possible example, the terminal device performs measurement on the first cell according to the first message, including:

[0053] If the terminal device satisfies the low-mobility judgment criterion and / or the judgment criterion of not being at the edge of a cell, and the serving cell does not support the target service, the terminal device performs measurement or adjusts measurement parameters and then performs measurement (that is, does not use relaxed measurement) on the first cell in at least one of the same frequency, different frequency, and different system. If the terminal device satisfies the low-mobility judgment criterion and / or the judgment criterion of not being at the edge of a cell, and the serving cell supports the target service, the terminal device performs relaxed measurement on the first cell in the same frequency.

[0054] In the embodiments of the present application, the terminal device is in an RRC inactive state or an idle state.

[0055] In the embodiments of the present application, for the terminal device in the idle state or the inactive state, the terminal device needs to perform measurement on a serving cell and a neighbor cell according to a measurement requirement in a cell reselection process. When the terminal device satisfies relaxed measurement on a neighbor cell using the same frequency as a serving cell, if the serving cell in which the terminal device currently camps does not support a target service, and there is a cell supporting the target service in the same frequency neighbor cell, in order to enable the terminal device to camp on the cell supporting the target service, the terminal device can perform normal measurement on the same frequency neighbor cell supporting the target service. If the serving cell in which the terminal device currently camps supports the target service, the terminal device can perform relaxed measurement or does not measure for a period of time on the same frequency neighbor cell, so as to reduce power consumption.

[0056] In the embodiments of the present application, for the terminal device in idle state or inactive state, the serving cell and the neighbor cell need to be measured according to the measurement requirement in the cell reselection process. The terminal device needs to camp on the cell supporting the target service preferentially, so the terminal device can perform normal measurement on the inter-frequency and / or inter-system neighbor cell supporting the target service, if the terminal device currently camps on the serving cell not supporting the target service, and there is a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell.

[0057] For example, in order to further meet the needs of users, a new measurement requirement (a measurement requirement specified in the protocol) can be introduced to require the terminal device to measure the neighbor cell in at least one of the same frequency, inter-frequency, and inter-system supporting the target service, that is, to perform measurement after adjusting the measurement parameter of the neighbor cell in at least one of the same frequency, inter-frequency, and inter-system supporting the target service, such as to require the terminal device to detect the cell on the frequency in at least one of the same frequency, inter-frequency, and inter-system more frequently, so as to discover the cell supporting the target service as soon as possible, so that the terminal device can camp on the cell in at least one of the same frequency, inter-frequency, and inter-system immediately when the cell meets the threshold of signal quality, so as to perform transmission of the target service subsequently.

[0058] Further, if the terminal device currently camps on the serving cell supporting the target service, the terminal device can perform relaxed measurement or no measurement for a period of time on the inter-frequency and / or inter-system neighbor cell, so as to reduce power consumption.

[0059] Optionally, when the priority of the target service supported by the serving cell is lower than the priority of the target service supported by the inter-frequency neighbor cell, the terminal device performs measurement or measurement after adjusting the measurement parameter on the first cell in the inter-frequency and / or inter-system.

[0060] In which, the terminal device can expect to establish multiple slices, which can correspond to one or more target services, so the terminal device can have multiple target services, and the target services corresponding to different slices can have the same priority or different priorities. Therefore, if the terminal device currently camps on the serving cell supporting the target service, there is also a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell, and the priority of the target service supported by the inter-frequency and / or inter-system neighbor cell is higher than the priority of the target service supported by the currently camped serving cell, the terminal device can perform normal measurement on the inter-frequency and / or inter-system neighbor cell, so as to discover the cell supporting the target service with higher priority as soon as possible, so as to perform transmission of the target service subsequently.

[0061] For example, the terminal device can introduce new measurement requirements (measurement requirements specified in the protocol) to require the terminal device to perform measurements on inter-frequency and / or inter-system neighboring cells that support higher priority target services according to the new measurement requirements. For example, the terminal device can be required to detect cells on inter-frequency and / or inter-system frequency points more frequently in order to discover cells that support target services as soon as possible. This allows the terminal device to immediately camp on inter-frequency and / or inter-system cells when the signal quality threshold is met, so that the target service can be transmitted subsequently.

[0062] In one possible example, the terminal device performs a measurement on the first cell based on the first message, including:

[0063] If the serving cell does not support the target service, the terminal device performs any one of the following on the first cell: measurement, measurement after adjusting measurement parameters, or relaxation measurement, for at least one of the following: same frequency, different frequency, or different system.

[0064] The terminal device is in an idle state, an inactive state, or a static state.

[0065] In this embodiment, for a terminal device in an idle or inactive state, when the terminal device receives a relaxed measurement standard, the terminal device can ignore the relaxed measurement standard or, after receiving the relaxed measurement standard, if the serving cell where the terminal device is currently camped does not support the target service, but there is a cell supporting the target service among at least one of the neighboring cells in the same frequency, different frequency, or different system, the terminal device can directly perform normal measurements on the neighboring cells in the same frequency, different frequency, or different system that support the target service. That is, after receiving the relaxed measurement standard, the terminal device does not determine whether it meets the low mobility judgment standard and / or the judgment standard that it is not at the cell edge. When the serving cell where the terminal device is currently camped does not support the target service, it directly performs normal measurements on the neighboring cells in the same frequency, different frequency, or different system that support the target service.

[0066] For example, to further meet user needs, new measurement requirements (as specified in the protocol) can be introduced, requiring terminal equipment to measure neighboring cells in at least one of the following frequencies (same frequency, different frequency, different system) that support the target service. That is, the terminal equipment adjusts the measurement parameters of the neighboring cells in at least one of the following frequencies (same frequency, different frequency, different system) that support the target service before performing the measurement. For example, the terminal equipment can be required to detect cells on at least one of the following frequencies more frequently in order to discover cells that support the target service as soon as possible. This allows the terminal equipment to immediately camp on a cell in at least one of the following frequencies (same frequency, different frequency, different system) when the signal quality threshold is met, so that the target service can be transmitted subsequently.

[0067] In the case of a terminal device in a static state, when the terminal device receives a relaxed measurement criterion, the terminal device can ignore the relaxed measurement criterion or, after receiving the relaxed measurement criterion, if the serving cell in which the terminal device is currently camped does not support a target service and there is a cell supporting the target service in a neighbor cell in at least one of the following: a same frequency, a different frequency, or a different system, the terminal device can directly perform normal measurement or relaxed measurement on the neighbor cell in at least one of the following: a same frequency, a different frequency, or a different system, supporting the target service, i.e., the terminal device does not determine whether the relaxed measurement criterion satisfies the static state determination criterion after receiving the relaxed measurement criterion, and directly performs normal measurement or relaxed measurement on the neighbor cell in at least one of the following: a same frequency, a different frequency, or a different system, supporting the target service, when the serving cell in which the terminal device is currently camped does not support the target service.

[0068] In a possible example, the terminal device performs measurement on the first cell according to the first message, including:

[0069] If the terminal device satisfies the static state determination criterion and the serving cell does not support the target service, the terminal device performs measurement or relaxed measurement on the first cell in a same frequency; if the terminal device satisfies the static state determination criterion and the serving cell of the terminal device supports the target service, the terminal device only performs measurement on the serving cell (i.e., can not measure a same frequency neighbor cell).

[0070] In the case of a terminal device in a static state, the static state is a state newly introduced by a protocol, e.g., whether the terminal device is in the static state can be determined according to a change in an accurate position of the terminal device, e.g., a change in RSRP of a serving cell in a period of time is lower than a preset threshold. It should be noted that the protocol can introduce other more accurate determination criteria, and the application does not limit the specific determination criteria of the static state.

[0071] In the embodiments of the application, for a terminal device in a static state, the terminal device also re-determines a measurement mode of a same frequency, different frequency, or different system neighbor cell according to a relaxed determination criterion. When the terminal device does not need to measure a same frequency neighbor cell (i.e., when the terminal device satisfies the static state and does not need to measure the same frequency neighbor cell), if the serving cell in which the terminal device is currently camped does not support a target service and there is a cell supporting the target service in a same frequency neighbor cell, the terminal device can perform measurement or relaxed measurement on the same frequency neighbor cell supporting the target service, so that the terminal device can camp on the cell supporting the target service.

[0072] Further, if the serving cell in which the terminal device is currently camped supports the target service, the terminal device can not perform measurement on the same frequency neighbor cell, to reduce power consumption.

[0073] In a possible example, the terminal device performs measurement on the first cell according to the first message, including: if the terminal device meets the stationary state judgment criterion and the serving cell of the terminal device does not support the target service, the terminal device performs measurement or performs relaxed measurement on the first cell of the inter-frequency and / or inter-system; if the terminal device meets the stationary state judgment criterion and the serving cell of the terminal device supports the target service, the terminal device performs measurement on the first cell of the inter-frequency and / or inter-system after a first time.

[0074] In the method, the terminal device is in a stationary state. For the terminal device in the stationary state, the terminal device needs to perform measurement on the serving cell and the neighbor cell according to the measurement requirement in the cell reselection process. When the terminal device does not need to perform measurement on the inter-frequency and / or inter-system neighbor cell, if the serving cell in which the terminal device currently resides does not support the target service, and there is a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell, in order to enable the terminal device to reside on the cell supporting the target service, the terminal device can perform measurement or perform relaxed measurement on the inter-frequency and / or inter-system neighbor cell supporting the target service. If the serving cell in which the terminal device currently resides supports the target service, the terminal device can not perform measurement on the inter-frequency and / or inter-system neighbor cell for a period of time, and perform measurement on the inter-frequency and / or inter-system neighbor cell after the period of time, so as to reduce power consumption. That is, for the terminal device in the stationary state, if the serving cell in which the terminal device currently resides supports the target service, the terminal device needs to perform measurement on the inter-frequency and / or inter-system neighbor cell at least once every period of time (for example, one hour), and can not perform measurement on the frequency point within one hour after the measurement is performed.

[0075] It should be noted that the present application can use the prior art to determine whether the terminal device meets the low mobility judgment criterion and / or the judgment criterion of not being at the edge of the cell. The specific judgment manner is not described herein again.

[0076] Optionally, the method further includes: the terminal device receives a third message from the serving cell, the third message being used to indicate at least one of frequency information, location area information and cell identification supporting the target service; and the terminal device determines the first cell according to the third message.

[0077] In the embodiments of the present application, before the first message is sent to the terminal device, the serving cell can first send a third message to the terminal device, and the third message can be a system message or a dedicated signaling. The dedicated signaling can be an RRC release message. The serving cell can indicate the frequency information supporting the target service, the location area information supporting the target service, or the cell identity of the target service cell in the system message or the dedicated signaling. After receiving the third message, the terminal device can determine whether the same frequency, different frequency or different system neighboring cell of the serving cell supports the target service. When the terminal device in the idle state or the inactive state does not camp on the cell supporting the target service, the terminal device needs to perform normal measurement on the same frequency, different frequency or different system neighboring cell which can support the target service. When the terminal device in the stationary state does not camp on the cell supporting the target service, the terminal device needs to perform relaxed measurement or no measurement for a period of time on the same frequency, different frequency or different system neighboring cell which can support the target service.

[0078] Optionally, the method further comprises: the terminal device receiving a second message from the serving cell, and the second message is used to indicate whether the terminal device applies the relaxed measurement; when the second message indicates that the terminal device does not apply the relaxed measurement, the terminal device performs measurement or adjusts the measurement parameter and then performs measurement on the neighboring cell supporting the target service.

[0079] Optionally, the method further comprises: the terminal device receiving a second message from the serving cell, and the second message is used to indicate whether the terminal device applies the relaxed measurement; when the second message indicates that the terminal device does not apply the relaxed measurement, the terminal device performs measurement or adjusts the measurement parameter and then performs measurement on the neighboring cell supporting the target service.

[0080] In the embodiments of the present application, the terminal device receives a first message from the serving cell, and the first message is used to configure a relaxed measurement standard. The terminal device performs measurement on a first frequency point corresponding to a first cell according to the first message, and the first cell is a neighboring cell supporting the target service. The present application can determine the measurement mode of the neighboring cell supporting the target service according to the configured relaxed measurement standard, so as to perform priority measurement on the neighboring cell supporting the target service, and further make the terminal device preferentially reselect the cell supporting the target service, thereby meeting the service requirement of the terminal device.

[0081] Please refer to Figure 3 , Figure 3 Another flowchart of a method for measuring a neighbor cell is provided in embodiments of the present application, which is applied to a communication system as shown in Figure 1 . As shown in Figure 3 , the method comprises the following steps.

[0082] S310, the terminal device receives a first message from a serving cell, the first message being used for configuring a relaxed measurement criterion, the relaxed measurement criterion comprising a low mobility judgment criterion.

[0083] The first message can be an SIB2 message, and the terminal device is in an RRC inactive state or an idle state. The serving cell where the terminal device is located can configure the judgment criterion of low mobility through the SIB2 message. After the terminal device determines that the relaxed measurement criterion is met, the terminal device can determine the measurement mode of the intra-frequency neighbor cell.

[0084] S320, if the terminal device meets the low mobility judgment criterion and the serving cell does not support a target service, the terminal device performs measurement or adjusts measurement parameters and then performs measurement on a first cell in at least one of an intra-frequency, inter-frequency, and inter-system; if the terminal device meets the low mobility judgment criterion and the serving cell supports the target service, the terminal device performs relaxed measurement on the first cell in at least one of the intra-frequency, inter-frequency, and inter-system, the first cell being a neighbor cell supporting the target service.

[0085] In embodiments of the present application, the target service can be an intended Slice, that is, a desired slice, one slice corresponding to one service type, and the terminal device expecting to establish a service of this service type in the future, such as a high-definition voice service, a high-definition video service, a low-latency service, a low-latency high-reliability service, etc.

[0086] For example, the first cell can also be a cell that the terminal device expects to access to support a multicast service, or a closed mode cell that belongs to a member. When the terminal device needs to preferentially access these cells, if the terminal device currently meets the relaxed measurement criterion, the terminal device can measure the cell supporting the multicast service or the closed mode cell belonging to the member by using the method described above, so as to camp on these cells as soon as possible.

[0087] It should be noted that the first cell can also be a cell that the terminal device expects to access in other application scenarios, or a cell supporting other expected services, which is not limited in embodiments of the present application.

[0088] SIB2 transmitted by the serving cell configures low mobility evaluation, but does not configure the criterion of not being at the cell edge. For the terminal device in the idle state or the inactive state, when the terminal device performs at least T SearchDeltaP measurement after selecting (reselecting) a cell on the same frequency, and the serving cell satisfies (Srxle vref Srxlev) < S SearchDeltaP That is, when the terminal device satisfies the low mobility evaluation criterion, if the target service is not supported by the serving cell in which the terminal device currently resides, and there is a cell supporting the target service in the same frequency neighbor cell, in order to enable the terminal device to reside on the cell supporting the target service, the terminal device can perform normal measurement or adjust the measurement parameter and then perform measurement (i.e., not use relaxed measurement) on the same frequency neighbor cell supporting the target service. If the target service is supported by the serving cell in which the terminal device currently resides, the terminal device can perform relaxed measurement or not measure for a period of time on the same frequency neighbor cell, so as to reduce power consumption.

[0089] SIB2 transmitted by the serving cell configures low mobility evaluation, but does not configure the criterion of not being at the cell edge. For the terminal device in the idle state or the inactive state, when the serving cell satisfies Srxlev> SnonIntraSearchP and Squal> SnonIntraSearchQ, and high priority measurement relaxation (highPriorityMeasRelax) is set to True; or the serving cell satisfies Srxlev≤ SnonIntraSearchP or Squal≤ SnonIntraSearchQ, if the target service is not supported by the serving cell in which the terminal device currently resides, and there is a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell, in order to enable the terminal device to reside on the cell supporting the target service, the terminal device can perform normal measurement (i.e., not use relaxed measurement) on the inter-frequency and / or inter-system neighbor cell supporting the target service. If the target service is supported by the serving cell in which the terminal device currently resides, the terminal device can perform relaxed measurement or not measure for a period of time on the inter-frequency and / or inter-system neighbor cell, so as to reduce power consumption.

[0090] Further, when the target service is supported by the serving cell in which the terminal device currently resides, there is also a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell, and the priority of the target service supported by the inter-frequency and / or inter-system neighbor cell is higher than the priority of the target service supported by the serving cell in which the terminal device currently resides, the terminal device can perform normal measurement on the inter-frequency and / or inter-system neighbor cell, so as to discover the cell supporting the target service with higher priority as soon as possible, so that subsequent transmission of the target service can be performed.

[0091] For example, the terminal device can also introduce a new measurement requirement (a measurement requirement specified in a protocol) to require the terminal device to measure a neighbor cell in at least one of the same frequency, different frequency, or different system supporting the target service according to the new measurement requirement. For example, the terminal device can be required to detect a cell on a frequency in at least one of the same frequency, different frequency, or different system more frequently, so as to discover a cell supporting the target service as soon as possible, so that when a cell in at least one of the same frequency, different frequency, or different system meets a signal quality threshold, the terminal device can immediately camp on the cell, so that subsequent transmission of the target service can be performed.

[0092] If the terminal device currently camps on a serving cell supporting the target service, the terminal device can perform relaxed measurement on a same-frequency neighbor cell or not measure for a period of time. The terminal device can determine whether the serving cell camps on a same-frequency neighbor cell supporting the target service from frequency information indicating that the target service is supported, location area information indicating that the target service is supported, or a cell identifier of a cell supporting the target service indicated by system information or dedicated signaling sent by the serving cell. The dedicated signaling can be an RRC release message. When the terminal device does not camp on a cell supporting the target service, the terminal device performs normal measurement on a same-frequency neighbor cell that can support the target service.

[0093] In the embodiments of the present application, when the terminal device in the idle state or the inactive state meets the judgment standard of low mobility, the measurement method of the neighbor cell in at least one of the same frequency, different frequency, or different system can be determined according to whether the serving cell supports the target service, so that the neighbor cell supporting the target service can be preferentially measured, and the terminal device can be preferentially reselected to the cell supporting the target service, thereby meeting the service requirement of the terminal device.

[0094] Referring to Figure 4 , Figure 4 Another neighbor cell measurement method flow diagram provided by the embodiments of the present application is applied to a communication system as shown in Figure 1 . As shown in Figure 4 , the method includes the following steps.

[0095] S410, the terminal device receives a first message from a serving cell, and the first message is used to configure a relaxed measurement standard, and the relaxed measurement standard includes a judgment standard of not being at a cell edge.

[0096] The first message can be an SIB2 message, and the terminal device is in an RRC inactive state or an idle state. The serving cell where the terminal device is located can configure the judgment standard of not being at a cell edge through the SIB2 message. After the terminal device determines that the relaxed measurement standard is met, the terminal device can determine the measurement method of the different frequency and / or different system neighbor cell.

[0097] S420, if the terminal device meets the criterion of not being at the cell edge and the serving cell does not support the target service, the terminal device performs measurement on the first cell in at least one of the intra-frequency, inter-frequency and inter-system or adjusts the measurement parameter and then performs measurement; if the terminal device meets the criterion of not being at the cell edge and the serving cell of the terminal device supports the target service, the terminal device performs relaxed measurement on the first cell in at least one of the intra-frequency, inter-frequency and inter-system, and the first cell is a neighbor cell supporting the target service.

[0098] In the embodiment of the present application, the target service can be an intended Slice, that is, a desired slice, one slice corresponds to one service type, and the terminal device expects to establish a service of this service type in the future, such as a high-definition voice service, a high-definition video service, a low-latency service, a low-latency high-reliability service, etc.

[0099] For example, the first cell can also be a cell that the terminal device expects to access to support multicast services or a closed mode cell belonging to a member. When the terminal device needs to preferentially access these cells, if the terminal device currently meets the relaxed measurement criterion, the terminal device can perform measurement on the cell supporting multicast services or the closed mode cell belonging to a member in the above-described manner to camp on these cells as soon as possible.

[0100] It should be noted that the first cell can also be a cell that the terminal device expects to access in other application scenarios or a cell supporting other expected services, and the embodiment of the present application does not limit this.

[0101] In the embodiment of the present application, the SIB2 sent by the serving cell configures the criterion of not being at the cell edge, but does not configure the low mobility criterion. For the terminal device in the idle state or the inactive state, when the serving cell meets Srxlev > Srxlevmin and Squal > Squalmin, that is, the terminal device meets the criterion of not being at the cell edge, if the serving cell of the terminal device does not support the target service, and there is a cell supporting the target service in the intra-frequency neighbor cell, in order to enable the terminal device to camp on the cell supporting the target service, the terminal device can perform normal measurement (that is, not relaxed measurement) on the intra-frequency neighbor cell supporting the target service. If the serving cell of the terminal device supports the target service, the terminal device can perform relaxed measurement or no measurement for a period of time on the intra-frequency neighbor cell to reduce power consumption. SearchThresholdP That is, when the terminal device meets the criterion of not being at the cell edge, if the serving cell currently camped by the terminal device does not support the target service, and there is a cell supporting the target service in the intra-frequency neighbor cell, in order to enable the terminal device to camp on the cell supporting the target service, the terminal device can perform normal measurement (that is, not relaxed measurement) on the intra-frequency neighbor cell supporting the target service. If the serving cell of the terminal device supports the target service, the terminal device can perform relaxed measurement or no measurement for a period of time on the intra-frequency neighbor cell to reduce power consumption.

[0102] In the idle state or inactive state, when the serving cell satisfies Srxlev≤SnonIntraSearchP or Squal≤SnonIntraSearchQ, and the terminal device satisfies the criterion for not being at the cell edge, if the terminal device currently resides in a serving cell that does not support the target service, and there is a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell, in order to enable the terminal device to reside in the cell supporting the target service, the terminal device can perform normal measurement (i.e., not relaxed measurement) on the inter-frequency and / or inter-system neighbor cell supporting the target service. If the terminal device currently resides in a serving cell that supports the target service, the terminal device can perform relaxed measurement or not measure for a period of time on the inter-frequency and / or inter-system neighbor cell to reduce power consumption.

[0103] Further, when the terminal device currently resides in a serving cell that supports the target service, there is a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell, and the priority of the inter-frequency and / or inter-system neighbor cell supporting the target service is higher than that of the currently residing serving cell supporting the target service, the terminal device can perform normal measurement on the inter-frequency and / or inter-system neighbor cell to quickly discover the cell supporting the higher priority target service, so that subsequent transmission of the target service can be performed.

[0104] For example, the terminal device can also introduce a new measurement requirement (a measurement requirement specified in the protocol) to require the terminal device to measure the inter-frequency and / or inter-system neighbor cell supporting the target service according to the new measurement requirement. For example, the terminal device can be required to detect the cell on the inter-frequency and / or inter-system frequency more frequently to quickly discover the cell supporting the target service, so that when the inter-frequency and / or inter-system cell satisfies the signal quality threshold, the terminal device can immediately reside in the cell to enable subsequent transmission of the target service.

[0105] In the idle state or inactive state, when the serving cell satisfies Srxlev≤SnonIntraSearchP or Squal≤SnonIntraSearchQ, and the terminal device satisfies the criterion for not being at the cell edge, if the terminal device currently resides in a serving cell that does not support the target service, and there is a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell, in order to enable the terminal device to reside in the cell supporting the target service, the terminal device can perform normal measurement (i.e., not relaxed measurement) on the inter-frequency and / or inter-system neighbor cell supporting the target service. If the terminal device currently resides in a serving cell that supports the target service, the terminal device can perform relaxed measurement or not measure for a period of time on the inter-frequency and / or inter-system neighbor cell to reduce power consumption.

[0106] In the embodiments of the present application, for the terminal device in the idle state or the inactive state, when the judgment criterion of not being at the cell edge is met, the measurement mode of the neighbor cell in at least one of the same frequency, different frequency and different system can be determined according to whether the target service is supported by the serving cell, so that the neighbor cell supporting the target service can be preferentially measured, and then the terminal device can be preferentially reselected to the cell supporting the target service, and the service requirement of the terminal device can be met.

[0107] Please refer to Figure 5 , Figure 5 Another neighbor cell measurement method flow diagram provided by the embodiments of the present application is applied to the communication system as shown in Figure 1 The method includes the following steps as shown in Figure 5 .

[0108] S510, the terminal device receives a first message from the serving cell, and the first message is used to configure the relaxed measurement standard, and the relaxed measurement standard includes the low mobility judgment criterion and the judgment criterion of not being at the cell edge.

[0109] The first message can be the SIB2 message, and the terminal device is in the RRC inactive state or the idle state. The serving cell of the terminal device can configure the judgment criterion of low mobility through the SIB2 message. After the terminal device determines that the relaxed measurement standard is met, the terminal device can determine the measurement mode of the same frequency neighbor cell.

[0110] S520, if the terminal device meets the low mobility judgment criterion and the judgment criterion of not being at the cell edge, and the serving cell does not support the target service, the terminal device performs measurement or adjusts the measurement parameter and then performs measurement on the first cell in at least one of the same frequency, different frequency and different system; if the terminal device meets the low mobility judgment criterion and the judgment criterion of not being at the cell edge, and the serving cell of the terminal device supports the target service, the terminal device performs relaxed measurement on the first cell in at least one of the same frequency, different frequency and different system, and the first cell is the neighbor cell supporting the target service.

[0111] In the embodiments of the present application, the target service can be the intended Slice, that is, the expected slice, one slice corresponds to one service type, and the terminal device establishes the service of this service type in the future, such as high-definition voice service, high-definition video service, low-latency service, low-latency high-reliability service, etc.

[0112] For example, the first cell can also be a cell that the terminal device expects to access to support multicast service, or a closed mode cell that the terminal device expects to access to belong to a member. When the terminal device needs to access these cells preferentially, if the terminal device currently satisfies the relaxed measurement criterion, the terminal device can perform measurement on the cell supporting multicast service or the closed mode cell belonging to a member in the above-described manner to camp on these cells as soon as possible.

[0113] It should be noted that the first cell can also be a cell that the terminal device expects to access in other application scenarios, or a cell supporting other expected services, which is not limited in the embodiments of the present application.

[0114] In the embodiments of the present application, the SIB2 sent by the serving cell configures a low mobility evaluation criterion (lowMobilityEvaluation) and a criterion for not being at the edge of the cell. For the terminal device in the idle state or the inactive state, when the terminal device performs normal measurement on at least one of the same frequency, different frequency, and different system for at least T SearchDeltaP measurements after reselecting a cell, and Srxlev>S SearchThresholdP , (Srxlev ref -Srxlev)<S SearchDeltaP , or the terminal device performs normal measurement on at least one of the same frequency, different frequency, and different system for at least T SearchDeltaP measurements after reselecting a cell, Srxlev>S SearchThresholdP , (Srxlev ref -Srxlev)<S SearchDeltaP , but is not configured with combineRelaxedMeasCondition, if the serving cell currently camped by the terminal device does not support a target service, and there is a cell supporting the target service in at least one of the same frequency, different frequency, and different system of the neighbor cell, the terminal device can perform normal measurement (i.e., not relaxed measurement) on the same frequency, different frequency, and different system of the neighbor cell supporting the target service, so that the terminal device can camp on the cell supporting the target service. If the serving cell currently camped by the terminal device supports the target service, the terminal device can perform relaxed measurement or no measurement for a period of time on the neighbor cell in at least one of the same frequency, different frequency, and different system, to reduce power consumption.

[0115] In the case of the terminal device in idle state or inactive state, when Srxlev≤SnonIntraSearchP or Squal≤SnonIntraSearchQ is met in the serving cell, if the serving cell where the terminal device currently resides does not support the target service, and there is a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell, in order to enable the terminal device to reside on the cell supporting the target service, the terminal device can perform normal measurement (i.e. without relaxed measurement) on the inter-frequency and / or inter-system neighbor cell supporting the target service. If the serving cell where the terminal device currently resides supports the target service, the terminal device can perform relaxed measurement or no measurement for a period of time on the inter-frequency and / or inter-system neighbor cell, so as to reduce power consumption.

[0116] Further, when the serving cell where the terminal device currently resides supports the target service, there is also a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell, and the priority of the cell supporting the target service in the inter-frequency and / or inter-system neighbor cell is higher than that of the serving cell where the terminal device currently resides, the terminal device can perform normal measurement on the inter-frequency and / or inter-system neighbor cell, so as to discover the cell supporting the target service with higher priority as soon as possible, so that subsequent transmission of the target service can be performed.

[0117] For example, the terminal device can also introduce a new measurement requirement (a measurement requirement specified in the protocol) to require the terminal device to measure the inter-frequency and / or inter-system neighbor cell supporting the target service according to the new measurement requirement, such as requiring the terminal device to detect the cell on the inter-frequency and / or inter-system frequency more frequently, so as to discover the cell supporting the target service as soon as possible, so that when the inter-frequency and / or inter-system cell meets the signal quality threshold, the terminal device can immediately reside on it, so that subsequent transmission of the target service can be performed.

[0118] In the case of the terminal device in idle state or inactive state, when Srxlev≤SnonIntraSearchP or Squal≤SnonIntraSearchQ is met in the serving cell, if the serving cell where the terminal device currently resides does not support the target service, and there is a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell, in order to enable the terminal device to reside on the cell supporting the target service, the terminal device can perform normal measurement (i.e. without relaxed measurement) on the inter-frequency and / or inter-system neighbor cell supporting the target service. If the serving cell where the terminal device currently resides supports the target service, the terminal device can perform relaxed measurement or no measurement for a period of time on the inter-frequency and / or inter-system neighbor cell, so as to reduce power consumption.

[0119] In the embodiments of the present application, when the terminal device meets the judgment criterion of low mobility and the judgment criterion of not being at the cell edge, the terminal device can determine the measurement manner of the neighbor cell in at least one of the intra-frequency, inter-frequency and inter-system according to whether the serving cell supports the target service, so that the neighbor cell supporting the target service can be measured preferentially, and the terminal device can be preferentially reselected to the cell supporting the target service, thereby meeting the service requirement of the terminal device.

[0120] Please refer to Figure 6 , Figure 6 Another flowchart of a method for measuring a neighbor cell is provided in the embodiments of the present application, which is applied to a communication system as shown in Figure 1 The method includes the following steps as shown in Figure 6

[0121] S610, the terminal device receives a first message from the serving cell, and the first message is used to configure a relaxed measurement criterion, and the relaxed measurement criterion includes a stationary state judgment criterion.

[0122] The first message can be an SIB2 message, and the terminal device is in the stationary state. The serving cell where the terminal device is located can configure the stationary state judgment criterion through the SIB2 message. After the terminal device determines that the relaxed measurement criterion is met, the terminal device can determine the measurement manner of the intra-frequency neighbor cell.

[0123] S620, if the terminal device meets the stationary state judgment criterion and the serving cell does not support the target service, the terminal device performs measurement or relaxed measurement on the first cell of the intra-frequency; if the terminal device meets the judgment criterion of low mobility and / or the judgment criterion of not being at the cell edge, and the serving cell of the terminal device supports the target service, the terminal device only performs measurement on the serving cell, and the first cell is the neighbor cell supporting the target service.

[0124] In the embodiments of the present application, the target service can be an intended Slice, that is, a desired slice. One slice corresponds to one service type, and the terminal device expects to establish a service of this service type in the future, such as a high-definition voice service, a high-definition video service, a low-latency service, a low-latency high-reliability service, etc.

[0125] For example, the first cell can also be a cell that the terminal device expects to access to support a multicast service, or a closed mode cell belonging to a member. When the terminal device needs to preferentially access to these cells, if the terminal device currently meets the relaxed measurement criterion, the terminal device can measure the cell supporting the multicast service or the closed mode cell belonging to the member by using the above-described method, so as to camp on these cells as soon as possible.

[0126] ​It should be noted that the first cell can also be a cell expected to be accessed by the terminal device in other application scenarios, or a cell supporting other expected services, and the embodiments of the present application do not limit this.

[0127] In the embodiments of the present application, the SIB2 sent by the serving cell configures the stationary state judgment criterion. For the terminal device in the stationary state, if the serving cell currently camped by the terminal device does not support the target service, and there is a cell supporting the target service in the co-frequency neighbor cell, in order to enable the terminal device to camp on the cell supporting the target service, the terminal device can perform measurement or perform relaxed measurement on the co-frequency neighbor cell supporting the target service. If the serving cell currently camped by the terminal device supports the target service, the terminal device can only perform measurement on the serving cell, and does not perform measurement on the co-frequency neighbor cell, so as to reduce power consumption.

[0128] If the terminal device does not currently camp on the cell supporting the target service, the terminal device can perform measurement or perform relaxed measurement on the co-frequency neighbor cell. The terminal device can obtain whether the co-frequency neighbor cell of the camped serving cell has a cell supporting the target service from the frequency information supporting the target service, the location area information supporting the target service, or the cell identifier of the cell supporting the target service indicated by the system information or the dedicated signaling sent by the serving cell. The dedicated signaling can be an RRC release message. When the terminal device camps on the cell supporting the target service, the terminal device only performs measurement on the serving cell, and does not perform measurement on the co-frequency neighbor cell supporting the target service.

[0129] In the embodiments of the present application, for the terminal device in the stationary state, the measurement manner on the co-frequency neighbor cell can be determined according to whether the serving cell supports the target service, so that the neighbor cell supporting the target service can be preferentially measured, and then the terminal device can be preferentially reselected to the cell supporting the target service, so as to meet the service demand of the terminal device.

[0130] Please refer to Figure 7 , Figure 7 Another neighbor cell measurement method flow diagram provided by the embodiments of the present application is applied to a communication system as shown in Figure 1 The method includes the following steps. Figure 7

[0131] S710, the terminal device receives a first message from the serving cell, and the first message is used to configure a relaxed measurement criterion, and the relaxed measurement criterion includes a stationary state judgment criterion.

[0132] ​The first message can be a SIB2 message, and the terminal device is in a stationary state. A serving cell in which the terminal device is located can configure a stationary state judgment criterion through the SIB2 message. After the terminal device determines that the criterion for relaxing measurement is met, the terminal device can determine a measurement manner for an inter-frequency and / or inter-system neighbor cell.

[0133] In S720, if the terminal device meets the stationary state judgment criterion and the serving cell of the terminal device does not support a target service, the terminal device performs measurement on a first cell of an inter-frequency and / or inter-system or performs relaxed measurement; if the terminal device meets the stationary state judgment criterion and the serving cell of the terminal device supports the target service, the terminal device performs measurement on the first cell of the inter-frequency and / or inter-system after a first time, and the first cell is a neighbor cell supporting the target service.

[0134] In the embodiment of the present application, the target service can be an intended slice, that is, a slice corresponding to a service type, and the terminal device expects to establish a service of the service type in the future, such as a high-definition voice service, a high-definition video service, a low-latency service, a low-latency high-reliability service, and the like.

[0135] In an example, the first cell can also be a cell to which the terminal device expects to access a multicast service or a closed mode cell belonging to a member. When the terminal device needs to preferentially access these cells, if the terminal device currently meets the criterion for relaxing measurement, the terminal device can perform measurement on the cell supporting the multicast service or the closed mode cell belonging to the member in the manner described above, so as to camp on these cells as soon as possible.

[0136] It should be noted that the first cell can also be a cell to which the terminal device expects to access in other application scenarios or a cell supporting other expected services, and the embodiment of the present application does not limit this.

[0137] In the embodiments of the present application, the SIB2 sent by the serving cell configures the static state judgment criterion. For the terminal device in the static state, if the serving cell currently camped by the terminal device does not support the target service, and there is a cell supporting the target service in the inter-frequency and / or inter-system neighbor cell, in order to enable the terminal device to camp on the cell supporting the target service, the terminal device can perform measurement or perform relaxed measurement on the inter-frequency and / or inter-system neighbor cell supporting the target service. If the serving cell currently camped by the terminal device supports the target service, the terminal device can not perform measurement on the inter-frequency and / or inter-system neighbor cell for a period of time, and after the period of time, perform measurement on the inter-frequency and / or inter-system neighbor cell, so as to reduce power consumption. That is, for the terminal device in the static state, if the serving cell currently camped by the terminal device supports the target service, the terminal device needs to perform measurement on the inter-frequency and / or inter-system neighbor cell at least once every period of time (for example, one hour), and can not perform measurement on the frequency point within one hour after the measurement is performed.

[0138] If the terminal device does not currently camp on the cell supporting the target service, the terminal device can perform measurement or perform relaxed measurement on the inter-frequency and / or inter-system neighbor cell. The terminal device can obtain whether the inter-frequency and / or inter-system neighbor cell of the serving cell has a cell supporting the target service from the frequency information supporting the target service, the location area information supporting the target service, or the cell identifier of the cell supporting the target service indicated by the system information or the dedicated signaling sent by the serving cell. The dedicated signaling can be an RRC release message.

[0139] In the embodiments of the present application, for the terminal device in the static state, the measurement mode of the inter-frequency and / or inter-system neighbor cell can be determined according to whether the serving cell supports the target service, so that the neighbor cell supporting the target service can be preferentially measured, and the terminal device can be preferentially reselected to the cell supporting the target service, and the service requirement of the terminal device can be met.

[0140] The above mainly introduces the scheme of the embodiments of the present application from the perspective of the method execution process. It can be understood that, in order to implement the above functions, the network device comprises the hardware structure and / or software module corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the unit and algorithm steps of each example described in the embodiments provided in the present application, the present application can be implemented in the form of hardware or the combination of hardware and computer software. Whether a certain function is implemented in the form of hardware or computer software driven hardware depends on the specific application and design constraints of the technical solution.
