Abstract
A subscriber controlled registration protocol, a subscriber monitors a congestion indicator signal broadcasted by a base station with which it desires to register. If the congestion indicator signal indicates that the base station is operating in a congested state, the mobile station selects another base station in the system. Otherwise, it attempts to register with the first selected base station.
Claims49
A registration method in a mobile station, comprising
- acquiring beacons in a communication system,
- ranking the beacons according to quality of reception for each beacon,
- selecting a highest of the ranked beacons,
- receiving a congestion indicator signal associated with the selected beacon, the congestion indicator signal indicating a neighbor congestion level of a source of a neighboring beacon,
- transmitting a registration request signal when the congestion indicator signal is in a first state, and
- repeating until all acquired beacons are exhausted.
