[0043] It should be understood that the terms "system" and "network" are often used interchangeably in this article.

[0046] The cell reselection process is a process in which an idle UE selects a better cell to provide service by monitoring the signal quality of the serving cell and neighboring cells.

[0047] Optionally, when the signal quality and level of a neighboring cell meet the S criterion and the cell reselection decision criterion, the UE may choose to camp on this cell.

[0048] The following briefly describes the cell reselection measurement criteria and cell reselection criteria related to the embodiments of the present application.

[0049] Cell reselection measurement criteria

[0050] The cell measurement may include intra-frequency measurement and inter-frequency or inter-access technology (Radio Access Technology, RAT) measurement.

[0051] 1. Same frequency measurement

[0052] Specifically, the UE can obtain the cell reselection parameters through the broadcast message, such as the same-frequency measurement start threshold, wherein the same-frequency measurement start threshold includes the same-frequency reference signal receiving power (Reference Signal Receiving Power, RSRP) threshold (ie, S intraserachP ) and the same-frequency reference signal receiving quality (Reference Signal ReceivingQuality, RSRQ) threshold (i.e. S intraserachQ ).

[0053] The UE may determine whether to start the intra-frequency measurement based on the measurement result of the serving cell and the intra-frequency measurement start threshold.

[0054] For example, the UE may not initiate the intra-frequency measurement when the measurement result of the serving cell does not meet the intra-frequency measurement initiation threshold. Otherwise, the intra-frequency measurement is initiated.

[0055] Optionally, the measurement result of the serving cell not meeting the same-frequency measurement start threshold may include S rxlev >S intraserachP , and S qual >S intraserachQ , otherwise, it means that the measurement result of the serving cell meets the same-frequency measurement start threshold. rxlev Indicates the RSRP related measurement results of the serving cell, for example, S rxlev =Qrxlevmeas-Qrxlevmin, where Qrxlevmeas represents the RSRP of the serving cell, Qrxlevmin can be -128dBm, for example, S qual Indicates the RSRQ related measurement results of the serving cell, for example, S qual It is equal to Qqualmeas-Qqualmin, where Qqualmeas represents the RSRQ of the serving cell, and Qqualmin can be -60, for example.

[0056] 2. Inter-frequency and inter-RAT measurements

[0057] Specifically, the cell reselection parameters, such as the inter-frequency measurement start threshold, may be acquired through a broadcast message, wherein the inter-frequency measurement start threshold includes the inter-frequency RSRP threshold (ie, S nonintraserachP ) and the same-frequency RSRQ threshold (i.e. S nonintraserachQ ).

[0058] The UE can determine whether to start inter-frequency or inter-RAT measurement based on the measurement result of the serving cell, the frequency reselection priority and the inter-frequency measurement start threshold.

[0059] For example, for an inter-frequency frequency or an inter-RAT frequency whose reselection priority is higher than the reselection priority of the current frequency, measurement is always performed.

[0060] For another example, for an inter-frequency frequency or an inter-RAT frequency whose reselection priority is lower than or equal to the reselection priority of the current frequency, measurement is performed according to the following rules:

[0061] If the measurement result of the serving cell does not meet the inter-frequency measurement start threshold, the inter-frequency or inter-RAT measurement is not started. Otherwise, the inter-frequency or inter-RAT measurement is started.

[0062] Optionally, the measurement result of the serving cell not meeting the inter-frequency measurement start threshold may include S rxlev >S nonintraserachP , and S qual >S nonintraserachQ , otherwise, it means that the measurement result of the serving cell meets the inter-frequency measurement start threshold. rxlev Indicates the RSRP related measurement results of the serving cell, for example, S rxlev =Qrxlevmeas-Qrxlevmin, where Qrxlevmeas represents the RSRP of the serving cell, Qrxlevmin can be -128dBm, for example, S qual Indicates the RSRQ related measurement results of the serving cell, for example, S qual It is equal to Qqualmeas-Qqualmin, where Qqualmeas represents the RSRQ of the serving cell, and Qqualmin can be -60, for example.

[0063] Cell reselection criteria

[0064] If there are multiple neighboring cells that meet the conditions at the highest priority, the best cell at the highest priority frequency is selected. For frequencies with the same priority, the R criterion for intra-frequency cell reselection can be used.

[0065] For example, for cell reselection of a high priority cell, the following conditions need to be met:

[0066] 1. The UE stays in the original cell for more than 1 second;

[0067] 2. The S value of the high priority frequency cell is greater than the preset threshold (ThreshXHigh: high priority reselection threshold value), and the duration exceeds the reselection time parameter T;

[0068] For another example, for cell reselection at the same frequency or frequency point with the same priority, the following conditions must be met:

[0069] 1. The UE stays in the original cell for more than 1 second;

[0070] 2. No cell with a high priority frequency meets the reselection requirements;

[0071] 3. The S value of the same-frequency or same-priority cell is less than or equal to a preset threshold (Sintrasearch: same-frequency measurement start threshold) and the R criterion (Rt>Rs) is continuously met within T time.

[0072] For another example, for cell reselection at a low priority frequency, the following conditions must be met:

[0073] 1. The UE stays in the serving cell for more than 1 second;

[0074] 2. No cell with a high priority (or equal priority) frequency meets the reselection requirements;

[0075] 3. The S value of the serving cell is less than the preset threshold (ThrshServLow: serving frequency low priority reselection threshold), and the S value of the low priority frequency cell is greater than the preset threshold (ThreshXLow: low priority reselection threshold value), and the duration exceeds the reselection time parameter value.

[0076] It should be understood that the cell reselection measurement criteria and cell reselection criteria in the above examples are only examples, and may be modified or adjusted with the development of communication technology, and the present application is not limited thereto.

[0077] It can be seen that in cell reselection measurement and cell reselection, the signal quality of the cell is mainly used as the judgment condition. The cell reselected based on this is the cell with good signal quality. However, after the introduction of network slicing, different cells may support different network slices, and the services transmitted by the terminal device may require the cell to support specific network slices. In this case, only the signal quality of the cell is considered for cell reselection, and a cell that does not support the network slice service required by the terminal may be reselected, affecting the terminal's service transmission.

In other words, the terminal device is able to obtain the network slice information of the terminal device, so that the information can be used when determining the priority.

[0146] In embodiment one, by determining the frequency corresponding to the network slice supported by the service cell or the frequency corresponding to the service cell as a high-priority frequency, it is beneficial to reselect the cell supporting the network slice of the terminal device during cell reselection, and further when the terminal device initiates a network slice-related service, it can ensure normal transmission of the service, thereby improving the user experience.

[0170] Embodiment 3

[0171] In this third embodiment, the target priority of the frequency point or cell may be determined based on the configuration of the network device.

[0172] Optionally, in some embodiments, the terminal device may obtain a frequency priority configuration information set from a network device, for example, the terminal device may obtain the frequency priority configuration information set from a broadcast message or RRC signaling of a serving cell. In other embodiments, the frequency priority configuration information set may also be preconfigured or predefined.

[0173] Optionally, the RRC signaling may be an RRC release message, or may be other RRC signaling, such as RRC dedicated signaling, but the present application is not limited thereto.

[0174] The terminal device can determine the frequency priority configuration information corresponding to the specific network slice in the frequency priority configuration information set as the target frequency priority configuration information based on the specific network slice, further determine the target priority based on the target frequency priority configuration information, and further perform cell reselection measurement and / or cell reselection based on the target priority.

[0175] As an embodiment, the specific network slice is indicated by a network device. For example, the network device may instruct the terminal device to determine the target priority information and / or the slice identifier (such as Slice ID, S-NSSAI, etc.) of the specific network slice according to the specific network slice through a first indication information. Optionally, the first indication information may be carried in any downlink signaling or downlink message, for example, RRC signaling (such as in an RRC Release message), or downlink control information (Downlink Control Information, DCI), etc.

[0176] It should be understood that the embodiments of the present application do not specifically limit the order in which the terminal device obtains the frequency priority configuration information set and the first indication information. In one implementation, the network device may first receive the first indication information, and learn that the target priority needs to be determined based on a specific network slice. Further, the frequency priority configuration information set sent by the network device may be received, and then the target priority information may be determined based on the specific network slice and the frequency priority configuration information set. In another implementation, the terminal device may also first receive the frequency priority configuration information set, and further, upon receiving the first indication information sent by the network device, the target priority information may be determined based on the specific network slice and the frequency priority configuration information set. In other words, the first indication information may be used to trigger the terminal device to determine the target priority based on information related to the network slice, and further perform cell reselection measurement and / or cell reselection based on the target priority.

[0177] Optionally, the terminal device may also determine whether to determine the target priority information according to the specific network slice and the frequency priority configuration information set, according to whether the frequency priority configuration information set is configured. For example, when the frequency priority configuration information set is configured, the target priority information is determined according to the specific network slice and the frequency priority configuration information set, or, if the frequency priority configuration information set is not configured on the terminal device, the terminal device may perform cell reselection measurement and / or cell reselection according to the frequency priority information or cell priority information configured in the RRC signaling or broadcast message.

[0178] Optionally, the specific network slice indicated by the network device may be determined based on the network slice information of the terminal device. For example, the specific network slice may be a network slice with the highest priority in the first network slice set, or a network slice that supports the service of the terminal device, or a network slice that the terminal device expects to select, etc.

[0179] As another embodiment, the specific network slice may be determined by the terminal device. For example, the terminal device may determine the specific network slice based on at least one of the relevant information of the network slice, such as the priority of the network slice, the type of the terminal device, and the type of service to be transmitted by the terminal device.

[0180] As an example, the specific network slice may be a high priority network slice, or a highest priority network slice.

[0181] As an example, the specific network slice may be the network slice that the terminal device desires to select (or is interested in, or requests).

[0182] Optionally, the type of the terminal device may be, for example, a URLLC terminal, an MTC terminal or an eMTC terminal, an eMBB terminal or a terminal in NB-IoT, etc. Different types of terminal devices may support different types of network slices. As an example, the terminal device may determine the network slice supported by the type of the terminal device as the specific network slice.

[0183] Optionally, the service type of the service to be transmitted by the terminal device may be, for example, Ultra-Reliable and Low Latency Communication (URLLC), machine type communication (MTC) or massive machine type communication (mMTC) service, Enhanced Mobile Broadband (eMBB), Industrial Internet of Things (IIOT) service, Narrow Band Internet of Things (NB-IoT) service, etc. The types of network slices required for different services may be different. As an example, the terminal device may determine the network slice that supports the service type of the service to be transmitted as the specific network slice.

[0184] In some embodiments of the present application, the terminal device determines the frequency priority configuration information corresponding to the specific network slice based on the specific network slice (determined or selected in the frequency priority configuration information set), and performs cell reselection measurement and / or cell reselection according to the frequency and / or frequency priority information obtained from the frequency priority configuration information.

[0185] Therefore, in this third embodiment, by performing cell reselection measurement and / or cell reselection according to the frequency priority configured by the network device, it is helpful to ensure that the terminal device reselects to a cell that supports the network slice of the terminal device, and further ensure the normal transmission of the service when the terminal device initiates a network slice-related service, thereby improving the user experience.

[0186] In the above embodiments, the terminal device may perform cell reselection measurement and / or cell reselection according to the first information within the first time duration. For example, in Embodiment 1 and Embodiment 2, the terminal device may perform cell reselection measurement and / or cell reselection according to the network slice information of the terminal device and / or the network slice information supported by the candidate cell within the first time duration. In Embodiment 3, the terminal device may perform cell reselection measurement and / or cell reselection according to the information in the frequency priority configuration information set within the first time duration. Outside the first time duration, the terminal device may perform cell reselection measurement and / or cell reselection according to the frequency priority information or cell priority information configured in the RRC signaling or broadcast message.

[0187] Optionally, the first duration may be configured by the network device, or may be preconfigured. For example, the network device may configure the first duration for the terminal device via RRC signaling, and optionally, the RRC signaling may be an RRC release message, or may be other RRC signaling, such as RRC dedicated signaling, and the present application is not limited thereto.

[0188] Optionally, the terminal device may perform cell reselection measurement and / or cell reselection according to the first information at a certain period, or may perform cell reselection measurement and / or cell reselection according to the first information based on a trigger of a network device (such as dedicated signaling, specific indication, etc.), but the present application is not limited to this.

[0189] Optionally, the first duration is the duration of a first timer, and the first timer may be configured by the network device, or may be preconfigured. For example, the network device may configure the first timer for the terminal device through RRC signaling, and optionally, the RRC signaling may be an RRC release message, or may be other RRC signaling, such as RRC dedicated signaling, and the present application is not limited thereto.

[0190] In some embodiments of the present application, the network device may configure a first timer in an RRC Release message to control the effective time for the terminal device to perform cell reselection based on slices. For example, if the terminal device receives the first timer configured in the RRC Release message, the first timer is started. During the operation of the first timer, the terminal device performs cell reselection based on the slice frequency priority, otherwise it performs cell reselection measurement and / or cell reselection based on the frequency priority given in the RRC dedicated signaling or the frequency priority given by the system broadcast.

[0191] In other embodiments of the present application, if the network slice of the terminal device is different from the network slice supported by the network device, the difference here may refer to partial difference or all difference. Alternatively, the terminal device does not support network slicing but the network device supports network slicing. In this case, it can be considered that the network slice of the terminal device does not match the network slice of the network device, or in other words, the terminal device and the network device do not match, and the terminal device is not a UE that matches the network device.

[0192] In some other embodiments of the present application, if the network slice of the terminal device and the network slice supported by the network device are partially the same, or the specific slices are the same, it can also be considered that the network slice of the terminal device and the network slice of the network device match, or in other words, the terminal device and the network device match, and the terminal device is a UE that matches the network device.

[0193] In some embodiments, the network device may indicate that the terminal device can access a cell or a restricted access cell under specific conditions. Optionally, the specific conditions may include a match between the network slice of the terminal device and the network slice of the network device. For example, the network device may send a second indication message to the terminal device, and the second indication message is used to indicate that a matching UE accesses or indicates that an unmatched UE cannot access, or the second indication message is used to indicate that the UE has restricted access and / or a restricted access cell. In this case, if the terminal device and the network slice do not match the network slice of the network device. In one implementation, for such UE, the UE may consider that the cell is not barred, but the cell is not a suitable cell, but an acceptable cell (e.g., only limited service transmission, such as emergency services). In another implementation, for such UE, the UE may also consider that the cell is barred, that is, it cannot be accessed.
