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
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.

1. A method for registration of a mobile device with a network having a standard cycle time requirement for interrupts and a registration period, the method comprising the steps of: a) setting a timer value on a timer at the mobile device, the timer value being a multiple of the standard cycle time
1. A method for registration of a mobile device with a network having a standard cycle time requirement for interrupts and a registration period, the method comprising the steps of: a) setting a timer value on a timer at the mobile device, the timer value being a multiple of the standard cycle time and greater than the standard cycle time;b) upon expiration of the timer, if the registration period minus a time elapsed since a previous registration message was sent is greater than the timer value, proceeding back to the setting step; andc) sending a registration message from the mobile device to the network. 2. The method of claim 1, wherein the multiple of the standard cycle time represents the shortest registration time allowed in the network. 3. The method of claim 1, wherein the network is a CDMA network. 4. The method of claim 1, wherein the timer is implemented in hardware. 5. The method of claim 1, further comprising the steps of repeating the setting step after the sending step. 6. The method of claim 1, wherein the expiration of the timer causes an interrupt to be sent to a processor on the mobile device. 7. The method of claim 6, wherein the processor counts the interrupts to determine the time elapsed since the previous registration message was sent. 8. A mobile device configured to register with a network having a standard cycle time requirement for interrupts and a registration period, the mobile device comprising: a processor;a timer;a communications subsystem comprising a transmitter and a receiver; andwherein the processor, timer, and communications subsystem cooperate to:a) set a timer value on the timer, the timer value being a multiple of the standard cycle time and greater than the standard cycle time;b) upon expiration of the timer, if the registration period minus a time elapsed since a previous registration message was sent is greater than the timer value, proceed back to set the tinier; andc) send a registration message to the network. 9. The mobile device of claim 8, wherein the multiple of the cycle time represents the shortest registration time allowed in the network. 10. The mobile device of claim 8, wherein the network is a CDMA network. 11. The mobile device of claim 8, wherein the timer is implemented in hardware. 12. The mobile device of claim 8, wherein the processor, timer and communications subsystem further cooperate to repeat the setting of the timer after the sending. 13. The mobile device of claim 8, wherein the expiration of the timer causes an interrupt to be sent to the processor. 14. The mobile device of claim 13, wherein the processor is configured to count the interrupts to determine the time elapsed since the previous registration message was sent.
