Abstract: A handover method includes receiving a handover requirement message from a source access network device, and sending a handover request message to the target access network device. The handover requirement message includes an identifier of a session of a terminal device. The session is to be handed over from the source access network device to a target access network device. The handover request message includes first single network slice selection assistance information (S-NSSAI). A first network slice of the target access network device that corresponds to the first S-NSSAI serves the session. The first S-NSSAI is determined based on second S-NSSAI and the first network slice supported by the target access network device, and the second S-NSSAI is of a second network slice of the source access network device and that corresponds to the identifier of the session.
