Wherein, the alternative switching target cell is one of the alternative switching cells; and the N cells corresponding to the N cell identifications comprise alternative switching cells.
In an embodiment of the present invention, a network side device may send N handover commands to a terminal device through M Radio Resource Control (RRC) messages. That is, the network side device may send M RRC messages to the terminal device, where the M RRC messages include N handover commands. M is not more than N.
The network side device provided in the embodiment of the present invention may be a base station, which may be a commonly used base station, an evolved node base (eNB), or a network side device in a 5G system (e.g., a next generation base station (gNB) or a network side device in a subsequent evolved communication system).
For example, it is assumed that a handover command sent by the network side device is received, where the handover command includes a cell identifier of cell 1. And cell 1 is an alternative handover cell. If the terminal equipment fails to switch the cell or fails to switch the wireless link, the terminal equipment executes the cell selection process, and if the terminal equipment selects the cell 1, the terminal equipment executes a switching command corresponding to the cell 1 and switches the cell 1. It can be understood that, at this time, the cell 1 is the alternative handover target cell.
For another example, assume that three handover commands sent by the network side device are received, where the three handover commands are handover command 1, handover command 2, and handover command 3. Wherein, the switching command 1 includes the cell identifier of the cell 1; the switching command 2 comprises the cell identification of the cell 2; the handover command 3 includes the cell identity of the cell 3.

For example, it is assumed that the terminal device is currently located in the source cell a, at this time, three handover commands sent by the network side device are received, where the three handover commands are handover command 1, handover command 2, and handover command 3. Wherein, the switching command 1 includes the cell identifier of the cell 1 and the incremental configuration information X of the cell 1 relative to the source cell a; the switching command 2 includes a cell identifier of the cell 2 and incremental configuration information Y of the cell 2 relative to the source cell a; the handover command 3 includes the cell identity of the cell 3 and incremental configuration information Z of the cell 3 with respect to the source cell a. Cell 1, cell 2 and cell 3 are all alternative handover cells.
When the terminal determines that a handover (e.g., handover from cell a to cell 4) needs to be performed, the terminal device first stores the configuration information in the source cell a and then performs a handover procedure. If the terminal equipment fails to switch the cell, the terminal equipment executes the cell selection process again, and if the terminal equipment selects the cell 2, the terminal equipment recovers the configuration of the source cell A, and then executes a switching command corresponding to the cell 2 to switch to the cell 2. And in the process of executing the switching command corresponding to the cell 2, configuring according to the configuration information of the source cell A and the increment configuration information Y of the cell 2 relative to the cell A.
When the terminal determines that a handover (e.g., handover from cell a to cell 4) needs to be performed, the terminal device first stores the configuration information in the source cell a and then performs a handover procedure. If the terminal equipment fails to switch the cell, the terminal equipment executes the cell selection process again, assuming that the terminal equipment selects the cell 2, the terminal equipment recovers to use the stored configuration of the source cell A first, then executes a switching command corresponding to the cell 2 to switch to the cell 2, assuming that the switching failure also occurs when the terminal equipment is switched to the cell 2, at the moment, the terminal equipment executes the cell selection process, assuming that the terminal equipment selects the cell 1, the terminal equipment recovers to use the stored configuration of the source cell A first, then executes the switching command corresponding to the cell 1, and switches to the cell 1. And in the process of executing the switching command corresponding to the cell 1, configuring according to the configuration information of the source cell A and the increment configuration information X of the cell 1 relative to the cell A.
When the terminal device fails in the wireless link, the terminal device executes the cell selection process, and assuming that the terminal device selects the cell 2, the terminal device first stores the configuration information of the source cell a, and then executes the handover command corresponding to the cell 2, and switches to the cell 2. And in the process of executing the switching command corresponding to the cell 2, configuring according to the configuration information of the source cell A and the increment configuration information Y of the cell 2 relative to the cell A.

If the terminal equipment fails to switch the cell or fails to switch the wireless link, the terminal equipment executes the cell selection process, and if the terminal equipment selects the cell 1, the terminal equipment executes a switching command corresponding to the cell 1 and switches the cell 1. It can be understood that, at this time, the cell 1 is the alternative handover target cell.
