Abstract:
1. In a mobile station connected to a first cellular base station transceiver system, a method of selecting a cellular base station transceiver system for communication with the mobile station, the method comprising: scanning to identify a second cellular base station transceiver system for communication; identifying, at the mobile station, that the second cellular base station transceiver system provides a predetermined communication service, and that the first cellular base station transceiver system fails to provide the predetermined communication service but provides a service that is less than the predetermined communication service; and in response to the identifying, causing the second cellular base station transceiver system to be selected for communication over the first cellular base station transceiver system even if signal quality of the second cellular base station transceiver system is worse than that of the first cellular base station transceiver system; wherein identifying whether the first and second cellular base station transceiver systems provide a predetermined communication service is based on identifying a protocol version broadcasted on a paging channel of the first and second cellular base station transceiver systems.
