Abstract
A mobile communication device wirelessly transfers user communications to a first wireless base station. The mobile communication device determines a first metric based on a load indicator for the first base station. The mobile communication device identifies a second wireless base station and determines a second metric based on a load indicator for the second base station. If the second metric is superior to the first metric, the mobile communication device determines if the second base station has sufficient performance characteristics for communication with the device. If the performance is sufficient, the mobile communication device initiates a hand-off from the first base station to the second base station. The mobile communication device may use additional factors to determine the first and second metrics.
