ABSTRACT:
Methods (100, 150, 200) and systems (10, 30, 41) are used to expedite access for a period of time for those subscriber units (30) which have previously executed the complete visited gateway access procedures. By checking certain information sent by a subscriber unit (30) upon initialization and determining whether the information falls within a predetermined period of time, the visited gateway (41) enables itself to receive calls directly from the subscriber unit (30) and informs the subscriber unit (30) that it (30) can send calls directly to the visited gateway (41). The subscriber unit (30) thereafter sends calls to the visited gateway (41) instead of to the home gateway (40) until it (30) is no longer allowed to do so.
