Abstract
Interoperability between wireless communication systems, such as the IS2000-1x and IS856 systems, is facilitated by using supervision timers. A wireless communication device starts one or more supervision timers and performs an intersystem transition. When the wireless communication device returns from the transition, the supervision timers are used to estimate the duration of the transition. The wireless communication device then performs a sequence of tasks appropriate to the estimated duration.
Claims51
A method comprising:
- starting a timer defined for use within a first wireless communication system;
- and
- estimating a duration of a transition from the first wireless communication system to a second wireless communication system as a function of the timer.
A processor-readable medium containing processor executable instructions for:
- starting a timer defined for use within a first wireless communication system;
- and
- estimating a duration of a transition from the first wireless communication system to a second wireless communication system as a function of the timer.
A wireless communication device comprising:
- first wireless communication system hardware for operating in a first wireless communication system;
- second wireless communication system hardware for operating in a second wireless communication system;
- an interoperation module to configure the wireless communication device in response to a transition between the first and second wireless communication systems, the interoperation module configured to estimate a duration of the transition as a function of a supervision timer.
An apparatus comprising:
- means for starting a timer defined for use within a first wireless communication system;
- and
- estimating a duration of a transition from the first wireless communication system to a second wireless communication system as a function of the timer.
A system comprising:
- a memory that stores processor-readable instructions;
- and
- a processor coupled to the memory that executes the instructions to start a timer defined for use within a first wireless communication system and to estimate a duration of a transition from the first wireless communication system to a second wireless communication system as a function of the timer.
