Abstract
A user terminal (UT) for a mobile satellite communications system, and an associated method for managing tracking areas for such a UT is provided. When initiating establishment of a radio connection, the UT transmits a connection request message to a satellite gateway (SGW) of the mobile satellite communications system, where the connection request message includes position information identifying a current location of the UT. The UT processes a connection setup message received in response to the connection request message, where the connection setup message includes a first tracking area identifier (TAID) that identifies a one of a plurality of tracking areas that is associated with the current location of the UT. The UT transmits a connection complete message to the SGW, together with an attach request message for a core network of the mobile satellite communications system, which includes the first TAID.
