System and method for registration and packet data reconnect

摘要

Methods, mobile stations and networks are provided that cause a packet data service reconnect to be performed automatically after the occurrence of an event triggering registration, even in some circumstances where such a data service reconnect would not normally occur. This avoids complications that can arise due to the packet data service being discontinued upon registration and the resulting inability to reach the mobile station.

主权项

1. A method in a mobile station, the method comprising:
entering a state associated with one of timer-based registration, distance-based registration, zone-based registration, parameter change registration, and user zone registration, wherein the state is associated with sending a registration message; determining if a packet zone list contains an entry with an active packet zone hysteresis timer for a current packet data service zone; and if the packet zone list contains the entry with the active packet zone hysteresis timer for the current packet data service zone,
cancelling the active packet zone hysteresis timer prior to its expiration;removing the entry from the packet zone list corresponding to the current packet data service zone;adding a new entry to the packet zone list corresponding current packet data service zone; andperforming an implicit access network registration by sending an origination message instead of the registration message.
