ABSTRACT:
A cordless telephone system synchronizes a frame number, a multi-frame number, and a primary scan carrier number (PSCN) of every base stations, to provide an inter-cell handover between the base station. The cordless telephone system includes a plurality of slave base station connectors each having a plurality of base stations connected thereto, a master base station connector having a plurality of the base stations connected thereto, and a plurality of DECT terminals connected to the base stations, wherein the cordless telephone system provides a radio communication service to a DECT terminal subscriber accommodated by a PABX or key system. The cordless telephone system initializes the slave base station connectors, requests a multi-frame transmission to the master base station connector when an interrupt for synchronization is generated, and transfers a multiframe number to the slave base station connector when a next interrupt is generated from the master base station connector. Therefore, a frame number and the multiframe number and a PSCN of all base stations are synchronized.
