Abstract

The present disclosure provides an information storage method, device, equipment and storage medium, and belongs to the technical field of communication. The method comprises: obtaining information configured by a network device for mobility management; reading and / or storing the information for mobility management. Therefore, in the information storage method provided by the present disclosure, the UE can directly read and / or store the information configured by the network device for mobility management. Since the UE can have read the information for mobility management in advance, the information for cell group activation can be configured and / or updated based on the information for mobility management subsequently, so that when the cell group is to be activated subsequently, the process of "reading the information for mobility management and configuring and / or activating the information for cell group activation" can not be performed again, and the cell group can be activated directly based on the information for cell group activation, thereby shortening the latency of selective activation of the cell group.

Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to an information storage method, apparatus, device and storage medium. Background Technology

[0002] In communication systems, due to the enhanced mobility under Release 18 (R18), selective activation of cell groups was introduced for R18. In this system, the UE receives and stores the configuration of cells to be activated from the network device, so that when the CG (Cell Group) to which the UE is connected changes, the configuration of the cells to be activated stored by the UE can still be executed without the network device reconfiguring or re-initializing the configuration of the cells to be activated. This reduces signaling overhead and the interruption time due to CG changes.

[0003] However, in related technologies, when the UE receives the configuration of the cell to be activated, it directly stores the configuration of the cell to be activated. Only when the activation condition is triggered will the configuration of the cell to be activated be read to perform selective activation of the cell group, which will result in a large delay in selective activation of the cell group. Summary of the Invention

[0004] The information storage method, apparatus, device, and storage medium disclosed herein are used to shorten the latency of selective activation of cell groups.

[0005] The method proposed in one embodiment of this disclosure, applied to a UE, includes: Obtain information configured on network devices for mobility management; Read and / or store the information used for mobility management.

[0006] The method proposed in another embodiment of this disclosure, applied to a network device, includes: Configure the UE with information for mobility management.

[0007] Another aspect of this disclosure provides an information storage device, comprising: The acquisition module is used to acquire network device configuration information for mobility management. A storage and retrieval module is used to read and / or store the information used for mobility management.

[0008] Another aspect of this disclosure provides an information storage device, comprising: The configuration module is used to configure information for mobility management to the UE.

[0009] Another aspect of this disclosure provides a communication device, the device including a processor and a memory, the memory storing a computer program, the processor executing the computer program stored in the memory to cause the device to perform the method as described in the preceding aspect of the embodiment.

[0010] Another aspect of this disclosure provides a communication device, the device including a processor and a memory, the memory storing a computer program, the processor executing the computer program stored in the memory to cause the device to perform the method proposed in the other aspect of the above embodiment.

[0011] Another aspect of this disclosure provides a communication device, comprising: a processor and an interface circuit; The interface circuit is used to receive code instructions and transmit them to the processor; The processor is configured to run the code instructions to perform the method as proposed in one aspect of the embodiments.

[0012] Another aspect of this disclosure provides a communication device, comprising: a processor and an interface circuit; The interface circuit is used to receive code instructions and transmit them to the processor; The processor is configured to run the code instructions to perform the method as proposed in another embodiment.

[0013] Another aspect of this disclosure provides a computer-readable storage medium for storing instructions that, when executed, cause the method described in one aspect of the disclosure to be implemented.

[0014] Another aspect of this disclosure provides a computer-readable storage medium for storing instructions that, when executed, cause the method as described in another aspect of this disclosure to be implemented.

[0015] In summary, in the information storage method, apparatus, device, and storage medium provided in the embodiments of this disclosure, the UE can obtain information configured by the network device for mobility management; subsequently, the UE can read and / or store the information for mobility management. Therefore, in the information storage method provided in this disclosure, the UE can directly read and / or store the information configured by the network device for mobility management. Since the UE may have already read the information for mobility management in advance, it can subsequently directly configure and / or update the information for cell group activation based on this information. This means that when activating a cell group later, it is unnecessary to perform the process of "reading the information for mobility management and configuring and / or activating / updating the information for cell group activation" again; instead, the cell group can be activated directly based on the information for cell group activation, thus shortening the latency of selective cell group activation.

[0020] The information storage method, apparatus, device, and storage medium provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0021] Figure 1a This is a flowchart illustrating an information storage method provided in an embodiment of the present disclosure. The method is executed by a UE (User Equipment, terminal device), such as... Figure 1a As shown, the information storage method may include the following steps: Step 101a: Obtain information configured by the network device for mobility management.

[0022] It should be noted that, in one embodiment of this disclosure, the UE can be a device that provides voice and / or data connectivity to a user. The terminal device can communicate with one or more core networks via a RAN (Radio Access Network). The UE can be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, or user agent. Alternatively, the UE can also be a device from an unmanned aerial vehicle. Alternatively, the UE can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle computer. Alternatively, the UE can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0023] In one embodiment of this disclosure, the information used for mobility management can be used for at least one mobility management operation. Specifically, in one embodiment of this disclosure, the at least one mobility management operation can be any existing or future mobility management operation, or any combination of such operations. The mobility management operation may include, for example, cell group activation, cell group handover, or conditional reconfiguration. Therefore, the mobility management configuration information can be information for cell group activation, information for cell group handover, or information for conditional reconfiguration. Furthermore, the information used for mobility management can correspond to different mobility management operations.

[0024] Furthermore, in one embodiment of this disclosure, the information for mobility management may include at least one of the following: add information for adding configuration items, delete information for deleting configuration items, modify information for modifying configuration items, and add / modify information for adding / modifying configuration items.

[0025] Specifically, in one embodiment of this disclosure, the added information, deleted information, modified information, or added / modified information each include at least one entry. This entry may include at least one of the following: a configuration identifier (e.g., a configuration ID (Identity, serial number)), a triggering condition for the mobility management operation, and configuration information of the cell group corresponding to the mobility management operation. Furthermore, in one embodiment of this disclosure, when the information used for mobility management is used to configure or update information used for cell group activation, the triggering condition for the aforementioned mobility management operation may include activation conditions for cell group activation and / or condition identification information corresponding to the activation conditions. Additionally, the configuration information for the cell group corresponding to the aforementioned mobility management operation may include corresponding configuration information for the cell group to be activated (e.g., handover-related configuration parameters corresponding to the cell group to be activated). 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.

[0026] 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.

[0027] 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 a message containing existing mobility management configuration 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, wherein the indication information can be used to explicitly or implicitly indicate whether the mobility management information is used for cell group activation.

[0028] 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 a first RRC (Radio Resource Control) message. And, in one embodiment of this disclosure, obtaining the mobility management information sent by the network device via the first RRC message may specifically be: obtaining the mobility management information sent by the network device via a first RRC reconfiguration message.

[0029] Furthermore, in one embodiment of this disclosure, the configuration information of at least one cell group in the mobility management information can be carried in at least one second RRC message of the cell group to be activated, wherein the second RRC message can specifically be included in the first RRC message, and the second RRC message can be a second RRC reconfiguration message.

[0030] In summary, the information storage method provided in this disclosure allows a UE to obtain information configured by the network device for mobility management. This information can then be used to configure or update information for cell group activation, enabling the UE to selectively activate cell groups based on this activation information. Therefore, this disclosure provides a cell activation method for selective activation of cells or cell groups by a UE in an MR-DC system. 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 and selectively activate cells or cell groups based on the aforementioned cell group activation information, thus reducing signaling overhead and the interruption time caused by CG changes.

[0031] Figure 1b This is a flowchart illustrating an information storage method provided in an embodiment of this disclosure. The method is executed by a UE, such as... Figure 1b As shown, the information storage method may include the following steps: Step 101b: Read and / or store information used for mobility management.

[0032] In one embodiment of this disclosure, after the UE obtains the mobility management information configured by the network device, it can first read and / or store the cell group configuration information in the mobility management information. Specifically, in one embodiment of this disclosure, the method by which the UE reads and / or stores the cell group configuration information in the mobility management information may include at least one of the following: Method 1: In response to the UE receiving cell group configuration information that is included in the information used for cell group activation, the UE can directly read and store the configuration from the cell group configuration information. The method for the UE to store the configuration from the cell group configuration information may include: the UE storing the configuration from the second RRC message corresponding to the cell group configuration information.

[0033] It should be noted that, in one embodiment of this disclosure, the information for activating cell groups may also include: one or more configuration information for mobility management operations for connecting cell groups (or cells).

[0034] Method 2: In response to the network device receiving cell group configuration information included in the information for cell group activation, the UE only stores the cell group configuration information. The method by which the UE stores the cell group configuration information may include: the UE directly storing the second RRC message corresponding to the cell group configuration information.

[0035] Method 3: The UE reads and stores the configuration information of the first cell group in the information used for mobility management, and the UE directly stores the configuration information of the second cell group in the information used for mobility management.

[0036] For example, in one embodiment of this disclosure, it is assumed that the information used for mobility management includes configuration information of the cell group corresponding to the MCG (Master Cell Group) and the cell group corresponding to the SCG (Secondary Cell Group). It is assumed that the second RRC message #1 carries the configuration information of the cell group corresponding to the MCG, and the second RRC message #2 carries the configuration information of the cell group corresponding to the SCG. Then, the UE can directly store the second RRC message #2 corresponding to the SCG, directly read the second RRC message #1 of the MCG, and store the configuration in the second RRC message #1. Alternatively, the UE can read both the second RRC message #1 and the second RRC message #2, and store the configurations in both messages.

[0037] Method 4: In response to the fact that the second RRC message used to carry the configuration information of the cell group in the UE includes the configuration information of multiple cell groups, the UE can read and store the configuration information of the first part of the cell group in the second RRC message, and the UE can directly store the configuration information of the second part of the cell group in the second RRC message.

[0038] For example, in one embodiment of this disclosure, it is assumed that the second RRC message includes configuration information for the cell group corresponding to the MCG and configuration information for the cell group corresponding to the SCG. Then, the UE can read only the configuration information for the cell group corresponding to the MCG and store the configuration from that information, while directly storing the configuration information for the cell group corresponding to the SCG. Alternatively, the UE can read both the configuration information for the cell group corresponding to the MCG and the configuration information for the cell group corresponding to the SCG, and store the read configuration.

[0039] Furthermore, it should be noted that, in one embodiment of this disclosure, the method for directly storing the configuration information of a cell group or directly storing the second RRC message of a cell group to be activated includes at least one of the following: The configuration information of the cell group can be stored directly through the RRC container, or the second RRC message of the cell group to be activated can be stored directly. The configuration information of the cell group is stored directly in CONTAINING format, or the second RRC message of the cell group to be activated is stored directly.

[0040] In one embodiment of this disclosure, the format of the aforementioned CONTAINING can specifically be an ASN.1 Contents Constraint. When the message, parameter, or configuration corresponds to a "CONTAINING" constraint, the UE does not need to perform automatic decoding or reading of its contained types. The UE can first use this Contents Constraint to decode the external PDU (Protocol Data Unit) type. Then, it can decode or read its nested contained types through separate steps. For this patent, constraining the second RRC message with "CONTAINING" means that the UE does not first decode or read the content of the second RRC message, but directly stores it.

[0041] In another embodiment of this disclosure, the configuration information of the cell group read above or the second RRC message of the cell group to be activated read above can be stored in one field or multiple fields.

[0042] Furthermore, it should be noted that in one embodiment of this disclosure, after the UE obtains the aforementioned information for mobility management, it may also store the information for mobility management.

[0043] Specifically, in one embodiment of this disclosure, in response to the fact that the information for mobility management is configured as independent information for cell group activation, the information for mobility management can be stored in a Var (variables) variable, wherein the Var variable can be used to store information for cell group activation.

[0044] Specifically, in one embodiment of this disclosure, in response to the fact that the information for mobility management is configured as independent information for cell group activation, the information for mobility management can be directly stored in an independent Var (variable) variable, wherein the independent Var variable is used alone to store the information for cell group activation.

[0045] In another embodiment of this disclosure, in response to the information for mobility management being used for at least one mobility management operation and being usable for cell group activation, the information for mobility management can be directly stored in an independent Var variable, wherein the independent Var variable is used solely to store information for cell group activation.

[0046] In another embodiment of this disclosure, in response to the fact that the mobility management information is configured as independent information for cell group activation, the mobility management information can be directly stored in a general Var variable, and an indication information is stored in the general Var variable corresponding to the mobility management information. The indication information is used to indicate that the corresponding information is used for cell group activation, wherein the general Var variable is used to store configuration information for various mobility management operations.

[0047] In another embodiment of this disclosure, in response to the information for mobility management being used for at least one mobility management operation and being usable for cell group activation, the information for mobility management can be directly stored in a general Var variable, and an indication information is stored in the general Var variable corresponding to the information for mobility management, the indication information being used to indicate that the corresponding information is used for cell group activation, wherein the general Var variable is used to store configuration information for various mobility management operations.

[0048] As can be seen from the above, after the UE obtains the information used for mobility management, it can read and / or store the information used for mobility management so that it can subsequently configure and / or update the information used for cell group activation based on the information used for mobility management.

[0049] In summary, in the information storage method provided in this disclosure, the UE can obtain information configured by the network device for mobility management; subsequently, the UE can read and / or store this mobility management information. Therefore, in the information storage method provided in this disclosure, the UE can directly read and / or store the mobility management information configured by the network device. Since the UE may have already read the mobility management information in advance, it can subsequently directly configure and / or update the information for cell group activation based on this mobility management information. This means that when activating a cell group later, it is unnecessary to perform the process of "reading the mobility management information and configuring and / or activating / updating the information for cell group activation" again; instead, the cell group can be activated directly based on the information for cell group activation, thus shortening the latency of selective cell group activation.

[0050] Figure 1c This is a flowchart illustrating an information storage method provided in an embodiment of this disclosure. The method is executed by a UE, such as... Figure 1c As shown, the information storage method may include the following steps: Step 101c: Obtain information configured by the network device for mobility management.

[0051] Step 102c: Read and / or store information used for mobility management.

[0052] For a detailed description of steps 101c-102c, please refer to the above embodiments; the embodiments disclosed herein will not be repeated here.

[0053] In summary, the information storage method provided in this disclosure allows a UE to obtain information configured by the network device for mobility management. This information can then be used to configure or update information for cell group activation, enabling the UE to selectively activate cell groups based on this activation information. Therefore, this disclosure provides a cell activation method for selective activation of cells or cell groups by a UE in an MR-DC system. 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 and selectively activate cells or cell groups based on the aforementioned cell group activation information, thus reducing signaling overhead and the interruption time caused by CG changes.

[0054] Figure 2a This is a flowchart illustrating an information storage method provided in an embodiment of this disclosure. The method is executed by a UE, such as... Figure 2a As shown, the information storage method may include the following steps: Step 201a: Obtain information configured by the network device for mobility management.

[0055] Step 202a: Read and / or store information used for mobility management. For a detailed description of steps 201a-202a, please refer to the above embodiments. This disclosure will not repeat the details here.

[0056] Step 203a: In response to information used for mobility management for cell group activation, configure or update the information used for cell group activation.

[0057] In one embodiment of this disclosure, the information used for cell group activation may include at least one of the following: 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. Information used 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. Information used for activating primary and secondary cell groups, specifically for activating both the primary and secondary cell groups. 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.

[0058] Furthermore, in one embodiment of this disclosure, each piece of information for cell group activation may include at least one cell group activation configuration. Different cell group activation configurations are used to activate the same or different cell groups, or to activate the same or different cells. For example, information for primary cell group activation may include at least one cell group activation configuration, information for secondary cell group activation may include at least one cell group activation configuration, and information for primary and secondary cell group activation may include at least one cell group activation configuration.

[0059] Furthermore, the configuration for activating the cell group may include at least one of the following: configuration ID, activation conditions for cell group activation, condition identifier information corresponding to the activation conditions, and configuration information of 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 information for primary cell group activation, information for secondary cell group activation, and information for 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). Based on the information configuration for mobility management, add or modify information for cell group activation (e.g., add or 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 information configuration).

[0060] 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 ID, 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 the configuration for the corresponding cell group activation to the corresponding information used for cell group activation.

[0061] 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 ID of configuration item #1 for cell group activation is the configuration ID included in entry #1. Similarly, entry #2 is stored as configuration #2 in the information for cell group activation, and the configuration ID of configuration #2 for cell group activation is the configuration ID included in entry #2. Likewise, entry #3 is stored as configuration #3 in the information for cell group activation, and the configuration ID of configuration #3 for cell group activation is the configuration ID included in entry #3.

[0062] 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 cell group activation of the primary cell group and stored in the information for cell group activation, and the configuration ID of configuration item #1 for cell group activation is the configuration ID 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 cell group activation of the secondary cell group and stored in the information for cell group activation, and the configuration ID of configuration item #2 for cell group activation is the configuration ID 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 cell group activation of both the primary and secondary cell groups and stored in the information for cell group activation, and the configuration ID of configuration item #3 for cell group activation is the configuration ID included in entry 3.

[0063] Furthermore, in one embodiment of this disclosure, the above-mentioned deletion operation may specifically be: deleting the cell group activation configuration corresponding to the configuration ID contained in each entry of the deletion information in the information used for cell group activation, that is, deleting the cell group activation configuration whose configuration ID is the same as the configuration ID of each entry in the deletion information.

[0064] For example, in one embodiment of this disclosure, suppose the deletion information includes entry #1, the configuration ID of which is ID#1, and the information for cell group activation includes two cell group activation configurations, namely configuration item #1 and configuration #2. Since the configuration ID of cell group activation configuration item #1 is ID#1 and the configuration ID of cell group activation configuration item #2 is ID#2, then cell group activation configuration item #1 can be deleted.

[0065] For example, in one embodiment of this disclosure, suppose the deletion information includes entry #1, where the configuration ID of entry #1 is ID#1, and the information for cell group activation includes two cell group activation configurations: configuration item #1 for activating the primary cell group and configuration item #2 for activating the secondary cell group. Since the configuration ID of configuration item #1 is ID#1 and the configuration ID of configuration item #2 are both ID#2, then configuration item #1 for cell group activation can be deleted.

[0066] Furthermore, in one embodiment of this disclosure, the aforementioned modification operation can specifically be: modifying the cell group activation configuration corresponding to the configuration ID contained in each entry of the modification information in the cell group activation information, that is, modifying the cell group activation configuration with the same configuration ID as the configuration ID in the entry based on each entry. Specifically, if an entry in the modification information contains the activation condition for cell group activation, the activation condition for cell group activation in the configuration of cell group activation with the same configuration ID as the entry can be replaced by the activation condition for cell group activation in the entry; or, if an entry in the modification information contains cell group configuration information, the configuration information for cell group activation in the configuration of cell group activation with the same configuration ID as the entry can be replaced by the configuration information for cell group activation in the entry.

[0067] For example, in one embodiment of this disclosure, it is assumed that the modification information includes entry #1, the configuration ID of which is ID#1, and that entry #1 may also include activation conditions for cell group activation. Furthermore, the information for cell group activation includes two cell group activation configurations: configuration item #1 for activating the primary cell group and configuration item #2 for activating the secondary cell group. Since the configuration ID of configuration item #1 is ID#1 and the configuration ID of configuration item #2 are both ID#1, 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.

[0068] Furthermore, in one embodiment of this disclosure, the above-mentioned add / modify operation can specifically be as follows: if the configuration ID corresponding to any cell group activation configuration in the information used for cell group activation is a configuration ID contained in an entry in the add / modify information, then modify the cell group activation configuration in the information used for cell group activation that corresponds to the configuration ID contained in the entry in the add / modify information based on that entry; if there is no cell group activation configuration in the information used for cell group activation that corresponds to a configuration ID contained in an entry in the add / modify information, then add the entry in the add / modify information to the information used for cell group activation. The modification method in this add / modify operation can mainly be as follows: if an entry in the modification information contains cell group activation conditions, then the cell group activation conditions in the cell group activation configuration with the same configuration ID as the entry can be replaced with the cell group activation conditions in the cell group activation configuration with the same configuration ID as the entry; or, if an entry in the modification information contains cell group configuration information, then the cell group configuration information in the cell group activation configuration with the same configuration ID as the entry can be replaced with the cell group configuration information in the cell group activation configuration with the same configuration ID as the entry.

[0069] For example, in one embodiment of this disclosure, assume that the added / modified information includes entries #1-3, where the configuration ID in entry #1 is ID#1, the configuration ID in entry #2 is ID#2, and the configuration ID in entry #3 is ID#3. Also, the information for cell group activation includes two cell group activation configurations: configuration item #1 with a corresponding configuration ID of ID#1, and configuration #2 with a corresponding configuration ID of ID#2. Based on this, the UE can modify configuration item #1 based on entry #1, such as replacing the activation condition of cell group activation in configuration item #1 with the activation condition of cell group activation in entry #1; modify configuration #2 based on entry #2, such as replacing the cell group configuration information in configuration #2 with the cell group configuration information in entry #2; and store entry 3 as configuration #3 for cell group activation in the information for cell group activation, with configuration ID ID#3 corresponding to configuration #3 for cell group activation.

[0070] For example, in one embodiment of this disclosure, it is assumed that the added / modified information includes entries #1-3, wherein the configuration ID in entry #1 is ID#1, the configuration ID in entry #2 is ID#2, the configuration ID in entry #3 is ID#3, and the information for cell group activation includes two cell group activation configurations, namely, configuration item #1 for activating the primary cell group with the corresponding configuration ID ID#1, and configuration item #2 for activating the secondary cell group with the corresponding configuration ID ID#2. Based on this, the UE can modify the cell group activation configuration item #1 based on item #1, such as replacing the cell group activation activation condition in the cell group activation configuration item #1 with the activation condition in item #1. Based on item #2, the UE can modify the configuration #2, such as replacing the cell group configuration information in the cell group activation configuration #2 with the cell group configuration information in item #2. Also, 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 at least one of the configuration ID, the triggering condition of the mobility management operation, and the configuration information of the cell group corresponding to the mobility management operation), then the UE can use item 3 as the cell group activation configuration #3 for activating the primary cell group and the secondary cell group and store it in the information for cell group activation, and the configuration ID corresponding to the cell group activation configuration #3 is ID #3.

[0071] In summary, in the information storage method provided in this disclosure, the UE can obtain information configured by the network device for mobility management; subsequently, the UE can read and / or store this mobility management information. Therefore, in the information storage method provided in this disclosure, the UE can directly read and / or store the mobility management information configured by the network device. Since the UE may have already read the mobility management information in advance, it can subsequently directly configure and / or update the information for cell group activation based on this mobility management information. This means that when activating a cell group later, it is unnecessary to perform the process of "reading the mobility management information and configuring and / or activating / updating the information for cell group activation" again; instead, the cell group can be activated directly based on the information for cell group activation, thus shortening the latency of selective cell group activation.

Figure 2b As shown, the information storage method may include the following steps: Step 201b: In response to information used for mobility management for cell group activation, configure or update the information used for cell group activation.

[0073] In summary, the information storage method provided in this disclosure allows the UE to configure or update the information for cell group activation based on the information used for mobility management. Subsequently, the UE can selectively activate cell groups based on this cell group activation information. Therefore, this disclosure provides a cell activation method for selective activation of cells or cell groups by MR-DC UEs. This ensures that when the CG connected to the UE changes, there is no need for network equipment to reconfigure or reinitialize the configuration of the cell to be activated. Instead, the UE can directly and selectively activate cells or cell groups based on the aforementioned cell group activation information, thus reducing signaling overhead and the interruption time caused by CG changes.
