Abstract: Methods for determining a tracking area is provided. One example method includes sending, by a terminal device, indication information to a core network device, where the indication information is used to indicate a position of the terminal device; and receiving, by the terminal device, first TA information from the core network device, where the first TA information includes a TA corresponding to the position of the terminal device, and the TA is determined based on the position of the terminal device. In the foregoing technical solution, the tracking area of the terminal device is managed based on the position of the terminal device, and the tracking area of the terminal device can be managed without depending on a cell ID change of the terminal device.
