FIELD: wireless communication.
SUBSTANCE: invention relates to wireless communication. In implementing the handover method, an accepted session ID and a rejected session ID are transmitted in a route switch request so that the core network device can determine the deactivated session from all stored sessions of the terminal. Thus, the core network device does not need to process such sessions, but only needs to process the accepted session and the rejected session, thereby improving processing efficiency.
EFFECT: increasing the rate of successful handover attempts.
