Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

The following is an introduction to relevant technologies in this field:

1. Switching or PSCell change process

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

The NR system supports conditional handover (CHO) and conditional PSCell change (CPC). The principles of CHO and CPC are similar, that is, the network device side preconfigures at least one preconfigured target cell and related execution through RRC signaling. Conditions are given to the UE. After receiving the CHO/CPC configuration information, the UE performs measurement and evaluation on the preconfigured target cell according to the execution conditions configured on the network device side. When the UE finds that there is a cell that meets the configured execution conditions, it determines the cell as Target cell, access the target cell, and complete the handover or PSCell change process.

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

The network device side can configure dual connectivity and carrier aggregation (CA) for the UE in order to increase the transmission bandwidth of the UE and improve throughput. Among them, when configuring dual connectivity for the UE on the network device side, the UE is configured with a master cell group (Master cell group, MCG) and a secondary cell group (SCG). The MCG and SCG can contain at least one serving cell, in which at least one serving cell can be included. Contains SpCell, where the SpCell in MCG is also called the primary serving cell (Primary Cell, PCell), the SpCell in SCG is called SPCell, and the other cells are SCell. The UE needs to perform wireless link monitoring and other activities on SpCell.

The NR system implements mobility management of SpCell by configuring Layer 3 handover or PSCell change, and implements mobility management of SCell by configuring RRC reconfiguration commands and adding/releasing SCell. However, currently special cells are usually specified during cell configuration through layer 3 commands, which always trigger random access. process, and there is no special cell management solution such as changing between special cells and configured serving cells to reduce the delay caused by triggering based on layer 3 commands.

Embodiments of the present application provide a cell management method, device, terminal and network equipment to implement special cell management such as changes between special cells and configured serving cells. Among them, the method and device (or terminal or network device) are based on the same application concept. Since the method and device (or terminal or network device) have similar principles for solving problems, the implementation of the method and device (or terminal or network device) can be References are made to each other, and duplications will not be repeated.

As shown in Figure 1, an embodiment of the present disclosure provides a cell management method, which includes the following steps:

When the corresponding bit is set to 1, it indicates that the first command is applied to the serving cell. After receiving the first command, the terminal will The target serving cell corresponding to the identification information is set to SpCell. Optionally, if the network device pre-configures one or more designated serving cells for the UE as a set of candidate cells that can be used as special cells, then the identification information of the target serving cell may be based on the set of candidate cells according to A certain preset rule is generated, for example, sorting in ascending order by the serving cell identifier to obtain the corresponding cell index or bitmap, or the cell index specified by the network signaling configuration, etc.

If the value is 0, it corresponds to the MCG. If the first command carries the identification information of the cell group, the UE is instructed that the first command applies to the cell group, for example, corresponding to MCG, and the UE is instructed that the target serving cell should be a special cell of MCG, that is, PCell, or perform a special The cell group in which the cell is changed is MCG.
