Abstract
To achieve soft handoff control between base transceiver stations (BTS) served by mobile telephone switching offices (MTSOs), a communication line logically isolated from the MTSOs is provided between adjacent BTSs. Traffic information is transferred between the BTSs via the communication line, thereby achieving a soft handoff with the control taken by one of the BTSs.
