ABSTRACT:
A mobile communications system including a plurality of base stations. The system includes a plurality of mobile telephones. Each mobile telephone communicates with at least a base station from the plurality of base station using a timeslot and a frame. The frame has a plurality of timeslots for the base station to use to communicate with the various of the plurality of mobile telephones in a cell covered by the base station. Each mobile telephone has a single radio capable of communication on various frequencies. The radio is not capable of communicating on different frequencies on adjacent timeslots in a frame. A mobile telephone may establish communication with a first base station on a particular timeslot in a frame. If another timeslot is available in the frame in a second base station, communication may be established with the second base station on another timeslot in the frame. The another timeslot is not next to the particular timeslot if the frequency used on the particular timeslot and the another timeslot are different. If the frequencies used on the particular timeslot and the another timeslot are the same, communication may be established with the second base station on the another timeslot in the frame where the another timeslot is next to the particular timeslot or not next to the particular timeslot.
