The following description is made with respect to related arts in the art:

1. handover or PSCell change procedure

The UE performs cell handover or PSCell change in the NR system is done based on the layer 3 command. Taking handover as an example, when the network device side determines that the UE performs handover, the source cell obtains a handover command by initiating a handover preparation procedure to the target cell, where the handover command includes configuration information of the target cell, where the handover command is radio resource control (Radio Resource Control, RRC) configuration information, and the source cell directly sends the handover command obtained from the target cell to the UE. After receiving the switching command, the UE synchronizes to the target cell according to the configuration information in the switching command, initiates a random access process, accesses the target cell, and completes the switching process.

The method comprises the steps that conditional handover (conditional Handover, CHO) and conditional PSCell change (conditional PSCell change, CPC) are supported in an NR system, the principles of CHO and CPC are similar, namely, at least one preconfigured target cell and relevant execution conditions are preconfigured by a network equipment side through RRC signaling to UE, after the UE receives CHO/CPC configuration information, measurement and evaluation are carried out on the preconfigured target cell according to the execution conditions configured by the network equipment side, when the UE finds that the cell meeting the configured execution conditions exists, the cell is determined to be the target cell, the target cell is accessed, and the handover or PSCell change process is completed.

2. Special Cell (SpCell) and Secondary Cell (SCell)

The network device side may configure dual connectivity and carrier aggregation (carrier Aggregation, CA) for the UE in order to increase the transmission bandwidth of the UE and improve throughput. The network device side configures a Primary Cell group (Master Cell group, MCG) and a secondary Cell group (secondary Cell group, SCG) for the UE, wherein the MCG and the SCG may include at least one serving Cell, at least one serving Cell includes a SpCell, the SpCell in the MCG is also referred to as a Primary serving Cell (PCell), the SpCell in the SCG is referred to as an SpCell, and the remaining cells are scells. The UE needs to perform actions such as radio link monitoring on the SpCell.

The NR system realizes the mobility management of the SpCell through configuration layer 3 switching or PSCell change, and realizes the mobility management of the SCell through configuration RRC reconfiguration command and adding/releasing the SCell. However, at present, the special cell is usually designated by the layer 3 command when the cell is configured, and the random access procedure is always triggered, but there is no special cell management scheme such as changing between the special cell and the configured serving cell, so that the time delay caused by triggering based on the layer 3 command is reduced.

The embodiment of the application provides a cell management method, a device, a terminal and network equipment, which are used for realizing special cell management such as change between a special cell and a configured service cell. The method and the apparatus (or the terminal or the network device) are based on the same application, and because the principles of the method and the apparatus (or the terminal or the network device) for solving the problem are similar, the implementation of the method and the apparatus (or the terminal or the network device) may refer to each other, and the repetition is omitted.

As shown in fig. 1, an embodiment of the present invention provides a cell management method, including the steps of:

step 11: the terminal receives a first command sent by network equipment; wherein the first command carries first information for indicating that the target serving cell is applied as a special cell.

Optionally, the target serving cell is a currently serving cell, that is, an existing serving cell. Or a serving cell configured for the UE, e.g. an SCell, i.e. the first information is used to indicate that an existing serving cell is to be applied as a special cell.

Step 12: the terminal executes special cell management according to the first command; wherein the special cell management includes applying the target serving cell as a special cell.

Optionally, the first command can only be applied to the serving cell configured by the cell group receiving the first command, or the serving cell of the terminal applying the first command is the serving cell applied to the cell group corresponding to the first command. For example, the first command is received through the MCG, the target serving cell is a serving cell in the MCG, and the special cell is a special cell of the MCG, i.e. a PCell.

Optionally, the special cell management includes, but is not limited to, at least one of: special cell addition or modification (e.g., applying a certain serving cell as a special cell), special cell identification information addition or modification, configuration (e.g., space division relation, BWP, PUCCH, RLM, BFD, etc.) corresponding to a target serving cell of activation or application indicated by a first command, management of cell states for a source special cell, management of cell states for other serving cells than the target serving cell, etc., wherein a cell state may be at least one of an activated state, a deactivated state, a dormant state, an activated state, and an activated BWP is a dormant BWP, etc. The embodiments of the present invention are not limited to the above.

In the above scheme, the terminal receives the first command sent by the network device, and executes special cell management including application of the target serving cell as a special cell according to the first information carried by the first command and used for indicating the application of the target serving cell as the special cell, thereby realizing special cell management including change between the special cell and the configured serving cell, and solving the problem that no scheme of special cell management such as change between the special cell and the configured serving cell exists at present.

Optionally, the first information includes at least one of:

identification information of the target service cell; the identification information of the target service cell is used for indicating the target service cell to which the first command is applied; the identification information may be a cell index (index), and the identification information may also be a bitmap (bitmap) corresponding to a serving cell, for example, each bit (bit) corresponds to one serving cell, when the corresponding bit is set to 1, the first command is indicated to be applied to the serving cell, and after receiving the first command, the terminal sets a target serving cell corresponding to the identification information as a scell. Alternatively, if the network device pre-configures one or more designated serving cells for the UE as an alternative cell set that may be used as a special cell, the identification information of the target serving cell may be generated according to a certain preset rule based on the alternative cell set, for example, obtaining a corresponding cell index or bitmap according to ascending order of serving cell identifiers, or configuring the designated cell index by network signaling, or the like.

The target service cell activates or applies the identification information of the first preconfigured cell; the identification information of the first preconfigured cell is used for indicating the service cell application or the activated preconfigured cell of the first command application. For example: each serving cell may be preconfigured with one or more preconfigured cells, where each preconfigured cell corresponds to a set of configuration information, and then the identification information of the activated or applied first preconfigured cell may be used to indicate to activate or apply the configuration information of the first preconfigured cell corresponding to the target serving cell; or each serving cell may be preconfigured with one or more preconfigured cells and each preconfigured cell may be preconfigured with one or more pieces of configuration information, the identification information of the activated or applied first preconfigured cell may be used to indicate to activate or apply the first preconfigured cell corresponding to the serving cell, and optionally, the first configuration information of the first preconfigured cell is activated or applied through the following first indication information.

The first indication information is used for indicating first configuration information of the first pre-configured cell activation or application; the first indication information is used for indicating a target service cell application of the first command application or first configuration information of an activated first pre-configured cell; for example: each serving cell configures at least one preconfigured cell, and when each preconfigured cell contains a plurality of configuration information, the first indication information can indicate the target serving cell application of the first command application or the first configuration information of the activated first preconfigured cell.

Second indication information for indicating to perform a special cell change; the second indication information is used for indicating that the special cell change is performed, that is, the first preset cell is used as the SpCell. For example: the first preset cell may be a serving cell with specific characteristics (e.g., a serving cell configured with PUCCH) or one or at least one serving cell pre-configured by the network device, etc.

Identification information of the cell group; for example: the cell group identification information is used for indicating a cell group corresponding to a serving cell, and if the cell group identification information is 0, the cell group corresponds to the MCG. If the first command carries the identification information of the cell group, the first command is indicated to be applied to the cell group by the UE, for example, the first command corresponds to the MCG, and the target serving cell is indicated to be applied as a special cell of the MCG, namely, the PCell, or the cell group which performs special cell change is indicated to be the MCG by the UE.
