Abstract
A mobile station is transitioned between control states in a telecommunications system based on available power at the mobile station. In an embodiment, a mobile station signals the system to indicate that power available to the mobile station is less than or greater than a predetermined threshold and that timers for controlling transitions between packet data service control states are adjusted accordingly. If power is below the predetermined threshold, the time period durations of transition timers for control states that require higher mobile station power can be reduced. The mobile station will then spend less time in those control states, thereby conserving battery power.
