MOBILE COMMUNICATION SYSTEM, BASE STATION DEVICE, AND HANDOVER METHOD

摘要

The communication paths between base stations are switched so that data transmitted from a mobile station during handover does not disappear. A base station (12) which is the handover destination includes an RTP communication control section (34) for receiving the RTP packet corresponding to a radio signal transmitted from a first mobile station from a base station which is the handover source and transferring the received RTP packet to the base station at the other end which communicates by radio with a second mobile station call-connected to the first mobile station upon start of the handover of the first mobile station, a voice comparing section (40) for determining the identity between voice information included in the received RTP packet and voice information included in the radio signal received from the first mobile station, and a transmission data switching section (42) for switching the RTP packet transmitted by the RTP communication control section (34) to the base station at the other end from the RTP packet received form the base station of the handover source to the RTP packet corresponding to the radio signal received from the first mobile station at the timing at which the identity of the voice information is confirmed.
