Abstract:
In a telecommunications system, a method of transitioning a mobile station between control states, said method comprising the steps of:determining available power for the mobile station; andsetting at least a first and a second parameter based on the result of said step of determining and a selected trade-off of service delay with mobile station power expenditure, said first and said second parameters defining a first and second transition time, respectively, each defining a duration of time the mobile station will remain in a first and a second control state, respectively, wherein the mobile station moves from said first control state to said second control state upon a detection of inactivity in said first control state for said duration of time defined by said first parameter and to a third control state upon a detection of inactivity in said second control state for said duration of time defined by said second parameter, and wherein mobile station power necessary to remain in each state decreases from said first control state and said second control state to said third control state.
