Abstract

A mobile communication device wirelessly transfers user communications to a first wireless base station. The mobile communication device identifies a second wireless base station that has sufficient performance characteristics for wireless communication with the mobile communication device and that has a higher communication priority than the first wireless base station. In response, the mobile communication device initiates a hand-off from the first wireless base station to the second wireless base station. In response to the hand-off, the mobile communication device stops the wireless transfer of the user communications to the first wireless base station and wirelessly transfers additional user communications to the second wireless base station.
