MOBILE COMMUNICATION METHOD AND WIRELESS BASE STATION

摘要

In a handover procedure between cells under different radio base stations (eNB), "RRC diversity" is implemented at the initiative of a network. A mobile communication method of the invention includes the steps of: causing a mobile station (UE) to transmit a "measurement report" to a radio base station (eNB #1); causing the radio base station (eNB #1) to transmit "CoMP preparation" to a radio base station (eNB #10) ; causing the radio base station (eNB #10) to transmit setting information on a cell (#10) to the radio base station (eNB #1) ; causing the radio base station (eNB #1) to conduct setting of the mobile station (UE) to perform CoMP transmission-reception; causing the mobile station (UE) to notify the radio base station (eNB #1) of radio quality in the cell (#10); and causing the radio base station (eNB #1) to instruct the mobile station (UE) to activate the CoMP transmission-reception.
