1. A method performed by Radio Access Network (RAN) node for supporting satellite wireless access of a user equipment (UE) to a serving public land mobile network (PLMN), the method comprising:
broadcasting one or more tracking area (TA) identities (TAIs) in a satellite radio cell;
receiving a non-access stratum (NAS) message from the UE, the NAS message sent by the UE in the satellite radio cell;
determining a TA in which the UE is located; and
sending the NAS message to a core network node, wherein the NAS message includes a TAI for the TA in which the UE is located and additionally includes the one or more TAIs broadcast in the satellite radio cell.
