Patent ID: 7283819

Claim:
A method for improved timer based registration for a mobile device with a network, the network having a standard cycle time for interrupts, the method comprising the steps of: a) receiving, at the mobile device, a system parameter message from the network, the message having a value indicating a frequency for periodic registration; b) setting a timer value on a timer at the mobile device, the timer value being greater than the standard cycle time and less than the frequency for periodic registration; c) setting a counter to count expiration of the timer; d) starting the timer; e) upon expiration of the timer, decrementing the counter; f) upon the counter expiring, setting a second timer value on the timer; g) setting the counter to count expiration of the timer; h) starting the timer; i) upon expiration of the timer, decrementing the counter; j) upon the counter expiring, waiting for a paging slot to communicate with the network; and k) sending a registration message to the network on the paging slot.
