ABSTRACT:
In a mobile communication system, a method and an apparatus for handing off a mobile station from a first channel on a serving base station to a second channel on a target base station, the mobile station transmitting at a first transmission phase on the first channel, the second channel being ready to take over the communication with the mobile station transmitting at a second transmission phase. A device for determining a time offset is provided in the target base station and is adapted to tune in to the mobile station for determining, prior to a handoff, the time offset between the first transmission phase and the second transmission phase. Also, a device is provided for shifting, upon handoff, the transmission phase of the mobile station by the determined time offset relative to the first transmission phase.
