ABSTRACT:
A method and apparatus for improved timer based registration for a mobile device with a network, the network having a standard slot cycle time for interrupts, the method comprising the steps of: receiving, at the mobile device, a system parameter message from the network, the message having a value indicating a frequency for periodic registration; setting a timer value on a timer at the mobile device, the timer value being greater than the standard slot cycle time; setting a counter to count expiration of the timer; starting the timer; upon expiration of the timer, decrementing the counter; upon the counter reaching zero, waiting for a paging slot to communicate with the network; and sending a registration message to the network on the paging slot.
