1. A method for performing a position area update for a wireless terminal in a wireless communication system configured to broadcast a plurality of position area codes, each position area code associated with one of a plurality of position areas, the method comprising:
- a. selecting a predetermined condition from a plurality of predetermined conditions, wherein the selecting is based at least in part on records of movement of the wireless terminal;
b. evaluating the predetermined condition upon movement of the wireless terminal from a first position area to a second position area; and
c. performing the position area update when the predetermined condition is met;
wherein each position area is defined as a portion of the wireless communication system that is used to service a corresponding geographical region, wherein movement from the first position area to the second position area triggers generation of a position area update request by the wireless communication system, and wherein performing the position area update comprises granting the position area update request by the wireless communication system.
