Before R18, cell switching can only be triggered by L3. L3 switching includes real-time switching and conditional switching.

Real-time switching: When the network decides to switch the UE from the current serving cell to another cell, the network sends a Radio Resource Control (RRC) reconfiguration message to the UE, which carries the configuration information required for the UE to access the target cell. When the UE receives the RRC reconfiguration message sent by the network, the UE applies the configuration information of the target cell included in the reconfiguration message, initiates random access with the target cell for synchronization, and feeds back an RRC reconfiguration completion message to the target cell to indicate to the network that the UE has successfully accessed the target cell.

Conditional switching: The network side pre-configures multiple target cells for the UE, that is, the configuration information and execution conditions of the target cells are sent to the UE in advance. When the UE receives the configuration information of the target cell, it will not immediately execute the switching or PSCell change or PSCell addition like the traditional switching, PSCell change or PSCell addition, but will save the received configuration and measure and evaluate the configured candidate cells until there is a cell that meets the execution conditions. The UE will then execute the stored reconfiguration message corresponding to the cell, perform the corresponding switching or PSCell change or PSCell addition process, that is, complete the downlink synchronization and trigger the random access process to access the target PCell or PSCell, and feedback the corresponding reconfiguration completion message to the network side.

Each embodiment of the present disclosure proposes a method and device for network-controlled continuous bottom-layer triggered mobility, and continuous LTM can be implemented through network-side configuration.

FIG. 1 is a schematic flow chart of a method for processing bottom-layer triggered mobility provided by an embodiment of the present disclosure. As shown in FIG. 1 , the method can be applied to a terminal device such as a UE, and the method at least includes the following steps:

Step 100: Receive an instruction message sent by a network device, wherein the instruction message is used to configure the terminal. The end device performs continuous bottom-layer triggered mobility.

Specifically, the UE receives an indication message sent by a network device, and the indication message is used to configure the UE to perform continuous bottom-layer triggered mobility, that is, to configure/instruct the UE whether to perform and how to perform continuous bottom-layer triggered mobility. After the UE receives the above indication message sent by the network device, it can perform relevant configurations on the local continuous bottom-layer triggered mobility based on the specific instructions of the indication message, and execute the continuous bottom-layer triggered mobility according to the relevant configurations.

The method for processing bottom-layer triggered mobility provided by the embodiment of the present disclosure sends an indication message for configuring the terminal device to perform continuous bottom-layer triggered mobility through a network side device to the terminal device, thereby realizing the network side configuration of continuous bottom-layer triggered mobility and enhancing LTM performance.

Optionally, the indication message may be a first indication message.

Accordingly, the receiving an indication message sent by the network device, where the indication message is used to configure the terminal device to perform continuous bottom-layer triggered mobility, may include:

Specifically, when the network device determines to pre-configure and/or update the continuous underlying layer triggered mobility of the UE, a first indication message can be sent to the UE, and the first indication message plays a role in configuring the terminal device to perform continuous underlying layer triggered mobility.

Information used to indicate the retention of continuous underlying triggered mobility of a specified type (e.g., intra-DU, inter-DU);

The network device determines to configure the UE to perform continuous bottom-layer triggered mobility, and the network device may send a first indication message. After the UE receives the first indication message, the UE may determine the mobility to be continuously triggered and/or determine the candidate cell corresponding to the mobility to be continuously triggered. The UE pre-configures the mobility of the continuous underlying layer triggering based on the specific instructions of the first indication message, or updates the configuration information that has been pre-configured locally. Subsequently, the UE can perform the mobility of the continuous underlying layer triggering based on the configuration information corresponding to the first indication message.

The UE may also retain and/or update all the pre-configured bottom-layer triggered mobility-related configuration information of the UE before after performing L1L2 mobility. The specific implementation is to make relevant settings according to the actual scenario requirements.

Optionally, the indication message may also be a second indication message.

Specifically, when the network device determines to stop and/or release the continuous underlying layer triggered mobility of the UE, a second indication message can be sent to the UE, and the second indication message plays a role in configuring the terminal device to perform continuous underlying layer triggered mobility.

Information used to indicate turning off the continuous bottom layer triggered mobility of a specified type (e.g., intra-DU, inter-DU);

Information used to indicate the release of continuous bottom-layer triggered mobility of a specified type (e.g., intra-DU, inter-DU)

If the network device determines to stop/release the continuous bottom-layer triggered mobility, the network device may send a second indication message. After the UE receives the second indication message, the UE may determine to stop and/or release the continuous bottom-layer triggered mobility and perform corresponding operations. That is, based on the specific instructions of the second indication message, the UE suspends the use of the relevant configuration of the UE's local continuous bottom-layer triggered mobility, or releases the configuration information that has been pre-configured locally. Subsequently, the UE may not perform continuous bottom-layer triggered mobility based on the configuration information corresponding to the second indication message.

Optionally, the method may further include:

Specifically, the UE receives a second indication message sent by the network device, and according to the second indication message, the UE determines to stop the mobility triggered by the continuous bottom layer, and the UE performs at least one of the following operations:
