Abstract:
1. A method for efficiently registering access terminals in wireless communications, comprising: providing a timer for an access terminal to register with a network; and operating the access terminal to send a registration message when both (1) the timer expires and (2) a location of the access terminal has changed from a previous location when a last registration message was sent by the access terminal to the network; operating the access terminal to use an identity of a base station serving the access terminal to determine whether the location of the access terminal has changed from the previous location; operating the access terminal to not send the registration message when the base station serving the access terminal remains the same after the timer expires; and operating the access terminal to send, after the timer expires, the registration message when the base station serving the access terminal is a different base station from an initial base station serving the access terminal when the last registration message was sent by the access terminal to the network.
