1. A method for processing handover, comprising:
in a process that a terminal device performs a Dual Active Protocol Stack (DAPS) handover,
handing over, by the terminal device, uplink data transmission to a target network device based on a random access between the terminal device and the target network device being successful;
performing, by the terminal device, following processes in a case that a preset condition comprising a Radio Link Failure (RLF) occurring in a connection between the terminal device and a source network device is met:
retaining related configuration information of the source network device without triggering a re-establishment of the connection with the source network device; and
receiving, by the terminal device, first indication information, and releasing a protocol stack of the source network device and a secret key associated with the source network device based on the first indication information.
