A method of interpreting location area information data in a satellite/terrestrial dual mode mobile terminal is provided, with the mobile terminal in the satellite mode and communicating with a satellite system. The method includes the steps of determining if a most recent registration of the mobile terminal was accomplished in the satellite or terrestrial mode and, if it is determined that the most recent registration of the mobile terminal was accomplished in the terrestrial mode, then determining if (1) a satellite operator ID broadcast by the satellite system matches a satellite operator ID from a most recent satellite location update of the mobile terminal, and (2) a satellite beam pair in a satellite spotbeam pair list broadcast by the satellite system matches a satellite beam pair in a satellite spotbeam ID from a most recent satellite location update of the mobile terminal. If matches are found at both steps (1) and (2) above, then the mobile terminal initiates a location update with the satellite system in the matching satellite beam pair determined at step (2). If matches are not found at either steps (1) and/or (2) above, then the mobile terminal initiates a location update with the satellite system in the satellite spotbeam ID broadcast by the satellite system.
