1. A communication method comprising:
sending, by a source core network element to a terminal device, a transfer instruction carrying indication for transferring the terminal device through a tracking area update (TAU) process;
receiving, by an access network device from the terminal device, a transfer request in response to the transfer instruction,
wherein the transfer request indicates the access network device to select a core network element; and
selecting, by the access network device in responsive to the transfer request, a target core network element for transferring the terminal device to the target core network element,
wherein the target core network element is different from the source core network element.
