The cell group to be activated may include at least one of a primary cell group, a secondary cell group, a primary cell group, and a secondary cell group. The primary cell group may include a primary cell and / or a secondary cell, and the secondary cell group may include a primary secondary cell and / or a secondary cell.

[0029] Furthermore, it should be noted that, in one embodiment of this disclosure, the aforementioned acquisition of network device configuration information for mobility management can specifically be: acquisition of independent network device configuration information for cell group activation for mobility management.

[0030] In another embodiment of this disclosure, obtaining the network device configuration information for mobility management can specifically involve: obtaining network device configuration information for performing at least one mobility management operation, wherein the information for performing at least one mobility management operation can be sent using the same message used to configure existing mobility management information. Furthermore, in one embodiment of this disclosure, when the UE obtains network device configuration information for performing at least one mobility management operation, the UE can also obtain indication information sent by the network device. This indication information can specifically be used to explicitly or implicitly indicate whether the mobility management information is used for one or more specific mobility management operations. Specifically, the indication information can specifically be used to explicitly or implicitly indicate whether the mobility management information is used for cell group activation. This part will be described in detail in subsequent embodiments.

[0031] Furthermore, in one embodiment of this disclosure, the method for obtaining mobility management information sent by a network device may include: obtaining mobility management information sent by the network device via broadcast and / or RRC (Radio Resource Control) messages. And, in one embodiment of this disclosure, obtaining mobility management information sent by the network device via RRC messages may specifically be: obtaining mobility management information sent by the network device via RRC reconfiguration messages.

[0032] Step 102: Configure or update information for cell group activation based on information used for mobility management.

[0033] In one embodiment of this disclosure, the information used for cell group activation may include at least one of the following: Configuration information used for activating the primary cell group; specifically, it can be used to activate the primary cell and / or the secondary cell of the primary cell group. Configuration information for activating secondary cell groups, specifically for activating the primary and secondary cells of the secondary cell group and / or the secondary cells of the secondary cell group. Configuration information for activating primary and secondary cell groups, used to simultaneously activate primary and secondary cell groups. Specifically, it can be used to activate at least one of the primary cell of the primary cell group, the secondary cell of the primary cell group, the primary and secondary cells of the secondary cell group, and the secondary cell of the secondary cell group.

[0034] Furthermore, in one embodiment of this disclosure, each piece of information for cell group activation may include at least one configuration item for cell group activation, wherein each configuration item is used to activate one or more cell groups, or for one or more cells. For example, configuration information for primary cell group activation may include at least one configuration item for primary cell group activation, configuration information for secondary cell group activation may include at least one configuration item for secondary cell group activation, and configuration information for both primary and secondary cell group activation may include at least one configuration item for both primary and secondary cell group activation.

[0035] Furthermore, the configuration item for cell group activation may include at least one of the following: configuration identifier, activation conditions for cell group activation, condition identifier information corresponding to the activation conditions, and configuration information for the cell group to be activated. Furthermore, in one embodiment of this disclosure, when the mobility management information configuration is used for cell group activation, the information for cell group activation can be updated based on the mobility management information configuration. In one embodiment of this disclosure, the specific operation of updating the information for cell group activation based on the mobility management information configuration may include at least one of the following: Add information for cell group activation based on the information configuration for mobility management (e.g., add at least one activation configuration based on the added information for primary cell group activation, secondary cell group activation, and both primary and secondary cell group activation). The deletion operation is performed on the information used for cell group activation based on the deletion information in the information configuration used for mobility management (e.g., the deletion operation is performed on at least one of the activation configurations for primary cell group activation, secondary cell group activation, and primary and secondary cell group activation based on the deletion information). Modify the information used for cell group activation based on the modified information in the information configuration used for mobility management (e.g., modify at least one of the activation configurations for primary cell group activation, secondary cell group activation, and primary and secondary cell group activation based on the modified information). Add or modify information for cell group activation based on information added or modified in the information configuration for mobility management (e.g., add or modify at least one activation configuration for primary cell group activation, secondary cell group activation, and primary and secondary cell group activation based on the added or modified information).

[0036] In one embodiment of this disclosure, the above-mentioned adding operation can specifically be: adding each entry in the added information to the information used for cell group activation. Specifically, in one embodiment of this disclosure, the selectively activated cell group to which each entry in the added information applies can be determined based on the information included in each entry in the added information (such as at least one of configuration identifier, triggering conditions for mobility management operations, and configuration information of the cell group corresponding to the mobility management operation), and then each entry in the added information can be added as a corresponding configuration item for cell group activation to the corresponding information used for cell group activation.

[0037] For example, in one embodiment of this disclosure, assuming the added information includes entries #1-#3, then entry #1 is stored as configuration item #1 in the information for cell group activation, and the configuration identifier of configuration item #1 for cell group activation is the configuration identifier included in entry #1. Similarly, entry #2 is stored as configuration item #2 in the information for cell group activation, and the configuration identifier of configuration item #2 for cell group activation is the configuration identifier included in entry #2. Likewise, entry #3 is stored as configuration item #3 in the information for cell group activation, and the configuration identifier of configuration item #3 for cell group activation is the configuration identifier included in entry #3.

[0038] For example, in one embodiment of this disclosure, assuming the added information includes entries #1-#3, if the information included in entry 1 determines that entry 1 is used for selectively activating the primary cell group, then entry 1 can be stored as configuration item #1 for primary cell group activation and stored in the information for cell group activation. The configuration identifier of configuration item #1 for primary cell group activation is the configuration identifier included in entry 1. Similarly, if the information included in entry 2 determines that entry 2 is used for selectively activating the secondary cell group, then entry 2 can be stored as configuration item #2 for secondary cell group activation and stored in the information for cell group activation. The configuration identifier of configuration item #2 for secondary cell group activation is the configuration identifier included in entry 2. Likewise, if the information included in entry 3 determines that entry 3 is used for selectively activating both the primary and secondary cell groups, then entry 3 can be stored as configuration item #3 for both primary and secondary cell group activation and stored in the information for cell group activation. The configuration identifier of configuration item #3 for both primary and secondary cell group activation is the configuration identifier included in entry 3.

[0039] Furthermore, in one embodiment of this disclosure, the above-mentioned deletion operation may specifically be: deleting the configuration items for cell group activation in the information for cell group activation that correspond to the configuration identifiers contained in each entry of the deletion information, that is, deleting the configuration items for cell group activation whose configuration identifiers are the same as the configuration identifiers of each entry in the deletion information.

[0040] For example, in one embodiment of this disclosure, suppose the deletion information includes entry #1, where the configuration identifier of entry #1 is ID#1, and the information for cell group activation includes two configuration items for cell group activation, namely configuration item #1 and configuration item #2. Since the configuration identifier of configuration item #1 for cell group activation is ID#1 and the configuration identifier of configuration item #2 for cell group activation are both ID#1, then configuration item #1 for cell group activation can be deleted.

[0041] For example, in one embodiment of this disclosure, suppose the deletion information includes entry #1, where the configuration identifier of entry #1 is ID#1, and the information for cell group activation includes two configuration items for cell group activation: configuration item #1 for activating the primary cell group and configuration item #2 for activating the secondary cell group. Since the configuration identifier of configuration item #1 for cell group activation is ID#1 and the configuration identifier of configuration item #2 for cell group activation are both ID#1, then configuration item #1 for cell group activation can be deleted.

[0042] Furthermore, in one embodiment of this disclosure, the aforementioned modification operation can specifically be: modifying the configuration items for cell group activation corresponding to the configuration identifiers contained in each entry of the modification information in the information used for cell group activation; that is, modifying the configuration items for cell group activation whose configuration identifiers are the same as those in each entry. Specifically, if an entry in the modification information contains activation conditions for cell group activation, the activation conditions for cell group activation in the configuration items for cell group activation whose configuration identifiers are the same as those in the entry can be used to replace the activation conditions for cell group activation in the configuration items for cell group activation whose configuration identifiers are the same as those in the entry; or, if an entry in the modification information contains cell group configuration information, the cell group configuration information in the entry can be used to replace the cell group configuration information in the configuration items for cell group activation whose configuration identifiers are the same as those in the entry.

[0043] For example, in one embodiment of this disclosure, it is assumed that the modification information includes entry #1, the configuration identifier of which is ID#1, and entry #1 may also include activation conditions for cell group activation. Furthermore, the information for cell group activation includes two configuration items for cell group activation: configuration item #1 for primary cell group activation and configuration item #2 for secondary cell group activation. Since the configuration identifier for primary cell group activation #1 is ID#1, and the configuration identifier for secondary cell group activation #2 is ID#2, the activation conditions for cell group activation in entry #1 can be used to replace the activation conditions for cell group activation in configuration item #1 for primary cell group activation.

[0044] Furthermore, in one embodiment of this disclosure, the above-mentioned add / modify operation may specifically be as follows: if the configuration identifier corresponding to any configuration item for cell group activation in the information for cell group activation is a configuration identifier contained in the entry in the add / modify information, then modify the configuration item for cell group activation in the information for cell group activation that corresponds to the configuration identifier contained in the entry in the add / modify information based on that entry; if there is no configuration identifier corresponding to a configuration item for cell group activation in the information for cell group activation that is a configuration identifier contained in the entry in the add / modify information, then add the entry in the add / modify information to the information for cell group activation.

[0045] For example, in one embodiment of this disclosure, assume that the added / modified information includes entries #1-3, wherein the configuration identifier in entry #1 is ID#1, the configuration identifier in entry #2 is ID#2, and the configuration identifier in entry #3 is ID#3; and the information for cell group activation includes two configuration items for cell group activation, namely configuration item #1 with a corresponding configuration identifier of ID#1 and configuration item #2 with a corresponding configuration identifier of ID#2. Based on this, the UE can modify configuration item #1 based on entry #1, modify configuration item #2 based on entry #2, and store entry 3 as configuration item #3 for cell group activation in the information for cell group activation, with the configuration identifier corresponding to configuration item #3 for cell group activation being ID#3.

[0046] For example, in one embodiment of this disclosure, it is assumed that the added / modified information includes entries #1-3, wherein the configuration identifier in entry #1 is ID#1, the configuration identifier in entry #2 is ID#2, the configuration identifier in entry #3 is ID#3, and the information for cell group activation includes two configuration items for cell group activation, namely configuration item #1 for primary cell group activation with corresponding configuration identifier ID#1, and configuration item #2 for secondary cell group activation with corresponding configuration identifier ID#2. Based on this, the UE can modify the configuration item #1 for activation of the primary cell group based on item #1, modify the configuration item #2 for activation of the secondary cell group based on item #2, and, assuming that the UE determines that item 3 is used to activate the primary cell group and the secondary cell group based on the information included in item 3 (such as configuration identifier, triggering conditions of mobility management operation, configuration information of the cell group corresponding to mobility management operation, etc.), then the UE can store item 3 as configuration item #3 for activation of the primary cell group and the secondary cell group and store it in the information for cell group activation, and the configuration identifier corresponding to configuration item #3 for activation of the cell group is ID#3.

[0047] In summary, in the cell activation method provided in this disclosure, the UE can obtain mobility management information configured by the network device and configure or update cell group activation information based on this mobility management information, so that the UE can selectively activate cell groups based on the cell group activation information. Therefore, this disclosure provides a cell activation method that can be used by MR-DC UEs for selective activation of cells or cell groups. When the CG connected to the UE changes, there is no need for the network device to reconfigure or reinitialize the configuration of the cell to be activated; instead, the UE can directly selectly activate cells or cell groups based on the aforementioned cell group activation information, thus reducing signaling overhead and the interruption time due to CG changes.

[0048] Figure 2 This is a flowchart illustrating a cell activation method provided in an embodiment of this disclosure. The method is executed by the UE, as follows: Figure 2 As shown, the cell activation method may include the following steps: Step 201: Obtain the network device configuration information for cell group activation and mobility management.

[0049] Step 202: Configure or update information for cell group activation based on information used for mobility management.

[0051] In summary, in the cell activation method provided in this disclosure, the UE can obtain mobility management information configured by the network device and configure or update cell group activation information based on this mobility management information, so that the UE can selectively activate cell groups based on the cell group activation information. Therefore, this disclosure provides a cell activation method that can be used by MR-DC UEs for selective activation of cells or cell groups. When the CG connected to the UE changes, there is no need for the network device to reconfigure or reinitialize the configuration of the cell to be activated; instead, the UE can directly selectly activate cells or cell groups based on the aforementioned cell group activation information, thus reducing signaling overhead and the interruption time due to CG changes.

[0052] Figure 3a This is a flowchart illustrating a cell activation method provided in an embodiment of this disclosure. The method is executed by the UE, as follows: Figure 3a As shown, the cell activation method may include the following steps: Step 301a: Obtain information configured on the network device for performing at least one mobility management operation.

[0053] Step 302a: Determine indication information, which is used to indicate whether the information used for mobility management is used for one or more specific mobility management operations. Specifically, the indication information may be used to indicate whether the entries in the information used for mobility management are used for cell group activation.

[0054] In one embodiment of this disclosure, determining the indication information may include: acquiring indication information sent by a network device, wherein the indication information may include a configuration identifier corresponding to at least one entry in the information used for mobility management, and the indication information is used to indicate whether the entry in the information used for mobility management corresponding to the configuration identifier included in the indication information is used for cell group activation. Specifically, in one embodiment of this disclosure, the indication information may be an indication code, which may be N bits, where N is a positive integer. When the indication code is a first value, it indicates that the entry in the information used for mobility management corresponding to the configuration identifier included in the indication information can be used for cell group activation; when the indication code is a second value, it indicates that the entry in the information used for mobility management corresponding to the configuration identifier included in the indication information cannot be used for cell group activation. For example, assuming the indication information is a 1-bit indication code, when the indication code is "1", it indicates that the entry in the information used for mobility management that corresponds to the configuration identifier included in the indication information can be used for cell group activation, and when the indication code is "0", it indicates that the entry in the information used for mobility management that corresponds to the configuration identifier included in the indication information cannot be used for cell group activation.

[0055] In another embodiment of this disclosure, determining the indication information may include: acquiring indication information sent by a network device, wherein the indication information includes a configuration identifier corresponding to at least one entry in the information for mobility management, and the indication information is used to indicate that the entry in the information for mobility management corresponding to the configuration identifier included in the indication information can be used for cell group activation. Specifically, when the UE receives the indication information, it indicates that the entry corresponding to the configuration identifier included in the indication information can be used for cell group activation; otherwise, it indicates that the information for mobility management cannot be used for cell activation.

[0056] It should be noted that, in one embodiment of this disclosure, the instruction information may be sent by the network device to the UE separately.

[0057] In another embodiment of this disclosure, the indication information may be included in any message sent by the network device to the UE. For example, the indication information may be included in information sent by the network device to the UE for mobility management.

[0058] Based on this, in one embodiment of the present disclosure, the aforementioned determination indication information may include: obtaining indication information included in entries for mobility management, the indication information being used to indicate whether the corresponding entry is used for cell group activation.

[0059] Specifically, in one embodiment of this disclosure, the indication information included in the entry can be an indication code, which can be N bits, where N is a positive integer. When the indication code is a first value, it indicates that the entry containing the indication information can be used for cell group activation; when the indication code is a second value, it indicates that the entry containing the indication information cannot be used for cell group activation. For example, assuming the indication information is a 1-bit indication code, when the indication code is "1", it indicates that the entry containing the indication information can be used for cell group activation; when the indication code is "0", it indicates that the entry containing the indication information cannot be used for cell group activation.

[0060] In another embodiment of this disclosure, the aforementioned determination of indication information may include: acquiring indication information included in entries for mobility management information, wherein the indication information is used to indicate that the corresponding entry can be used for cell group activation. Specifically, if an entry includes indication information, it indicates that the entry can be used for cell group activation; otherwise, it indicates that the entry cannot be used for cell activation.

[0062] The aforementioned method for configuring or updating information for cell group activation based on information used for mobility management may include at least one of the following: In response to the UE receiving an indication message, and the indication message indicating that the entry in the information for mobility management that corresponds to the configuration identifier included in the indication message is used for cell group activation, the information for cell group activation is configured or updated based on the entry in the information for mobility management that corresponds to the configuration identifier included in the indication message. In response to the UE receiving the indication information, the information for cell group activation is configured or updated based on the entry corresponding to the configuration identifier included in the indication information in the information for mobility management. In response to an entry in the information for mobility management that includes an indication sent by a network device, and the indication indicates that the corresponding entry is for cell group activation, the information for cell group activation is configured or updated based on the entry in the information for mobility management that includes the indication. In response to entries for mobility management that include indication information, information for cell group activation is configured or updated based on entries for mobility management that include indication information.

[0063] For further details regarding steps 301a-303a, please refer to the description in the above embodiments; these details will not be repeated here.

[0064] In summary, in the cell activation method provided in this disclosure, the UE can obtain mobility management information configured by the network device and configure or update cell group activation information based on this mobility management information, so that the UE can selectively activate cell groups based on the cell group activation information. Therefore, this disclosure provides a cell activation method that can be used by MR-DC UEs for selective activation of cells or cell groups. When the CG connected to the UE changes, there is no need for the network device to reconfigure or reinitialize the configuration of the cell to be activated; instead, the UE can directly selectly activate cells or cell groups based on the aforementioned cell group activation information, thus reducing signaling overhead and the interruption time due to CG changes.

The method is executed by the UE, as follows: Figure 3b As shown, the cell activation method may include the following steps: Step 301b: Obtain information configured on the network device for performing at least one mobility management operation.

[0066] Step 302b: Determine indication information, which is used to indicate whether the information used for mobility management is used for one or more mobility management operations in the at least one mobility management. Specifically, the indication information can be used to indicate whether the information used for mobility management is used for cell group activation.

[0067] In one embodiment of this disclosure, determining the indication information may include: acquiring indication information sent by a network device, wherein the indication information is used to indicate whether information used for mobility management is used for cell group activation. Specifically, in one embodiment of this disclosure, the indication information may be an indication code, which may be M bits, where M is a positive integer. When the indication code is a third value, it indicates that the information used for mobility management can be used for cell group activation; when the indication code is a fourth value, it indicates that the information used for mobility management cannot be used for cell group activation. For example, assuming the indication information is a 1-bit indication code, when the indication code is "1", it indicates that the information used for mobility management can be used for cell group activation; when the indication code is "0", it indicates that the information used for mobility management cannot be used for cell group activation.

[0068] In another embodiment of this disclosure, determining the indication information may include: acquiring indication information sent by a network device, wherein the indication information is used to indicate that information used for mobility management can be used for cell group activation. Specifically, when the UE receives the indication information, it indicates that the information used for mobility management can be used for cell group activation; otherwise, it indicates that the information used for mobility management cannot be used for cell group activation.

[0069] It should be noted that, in one embodiment of this disclosure, the instruction information may be sent by the network device to the UE separately.
