1. A tracking area (TA) update method, comprising:
receiving, by a terminal device, a broadcast message periodically sent by a satellite device, wherein the broadcast message alternately carries tracking area codes (TACs) corresponding to one or more TAs of at least two TAs, and wherein coverage of a beam of the satellite device belongs to the at least two TAs;
recording, by the terminal device when detecting for a first time that a TA corresponding to a TAC in a current broadcast message received in a current period does not belong to a first TA list, the TA in a second TA list, wherein the first TA list comprises one or more first TAs configured to page the terminal device, and wherein the second TA list is configured to store a detected TA that is not in the first TA list;
continuing to detect, by the terminal device, a subsequent broadcast message; and
determining, based on a subsequent TAC in the subsequent broadcast message, whether to initiate a TA update procedure to update the first TA list.
