Abstract

The present invention provides a handover method and a terminal, the method comprising: in the process of conditional handover, receiving a handover command sent by a source cell, the terminal falls back to the handover process indicated by the handover command; or, the The terminal continues to perform the conditional handover; wherein, the handover command does not carry the trigger condition of the conditional handover; in the embodiment of the present invention, when the terminal receives the normal handover command sent by the source cell during the conditional handover, the terminal falls back to the normal handover command. The switching process or continuing to perform conditional switching can ensure the integrity of signaling and improve the switching process.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a handover method and a terminal. Background technique [0002] In the existing handover process, when the terminal initiates handover to the target cell, it will no longer receive configuration or related instruction information of the source cell. [0003] In order to prevent the terminal from being unable to receive the handover command related message of the source cell after the channel condition of the source cell deteriorates, thereby causing handover failure, a conditional handover (Conditional Handover) process is introduced. [0004] The main steps of the existing conditional switching process are as follows: [0005] Step 1, the source cell sends handover request information to one or more target cells. [0006] Step 2, the target cell feeds back handover confirmation information to the source cell. [0007] Step 3, the source cell sends configurati...
