Abstract

The mobile telephone time advance system hands over from a first base station (BTS1) to a second base station (BTS2) when coverage in the first base area is lost. A mobile telephone (MS) time division multiplexes information, and when a handover command is received a predetermined time advance (TA-BTS2) from the second station is applied reducing the handover time when signals are not received.
