Abstract:
1. A method of operating a mobile station in a wireless network system comprising a plurality of base stations, comprising: receiving the messages from a first base station of the wireless network system to which the mobile station is connected; determining a first averaged signal strength of the messages received from the first base station; determining a scan period according to the first averaged signal strength; performing a background scan, at intervals during the scan period, to monitor messages from the plurality of base stations of the wireless network system; providing a series of signal strength ranges, each corresponding to a respective time interval, determining to which the first averaged signal strength conforms to, and utilizing the corresponding time interval as the scan period; determining a second averaged signal strength of the messages sent from a second base station selected from the plurality of base stations of the wireless network system; determining a difference between the first averaged signal strength and the second averaged signal strength; and monitoring the difference for a preset period of time, when the difference remains exceed a preset threshold for the preset period of time, establishing a connection between the mobile station and the second base station rather than the first base station.
