Abstract

A wireless telecommunications system is disclosed that hands off a wireless terminal from one base station to another as the wireless terminal moves within a wireless telecommunications system. Each pair of communications channels (forward and reverse) that are used by the system for communication with a specific wireless terminal are not associated with a specific base station. Instead, the pair of communications channels are associated with the wireless terminal and are used by the wireless terminal both before and after a hand off. Before the hand off, the wireless terminal uses the pair of communications channels for communicating with a first base station. To accomplish the hand off to a second base station, the first base station stops using the communications channels at the same time that the second base station starts using them. Although the wireless terminal is handed off from the first base station to the second base station, re-tuning of the wireless terminal is not required.
