Radio communication system, base station, gateway, and radio communication method

摘要

The radio communication system of the present invention includes a base station (10), a mobility management node (20), and a gateway (30). The base station (10) transmits to the mobility management node (20) information of the origination addresses of neighboring base stations of the base station (10). The mobility management node (20) receives information of the origination addresses of the neighboring base stations from the base station (10) and transmits the information of the origination addresses of the neighboring base stations to the gateway (30). The gateway (30) receives information of the origination addresses of the neighboring base stations from the mobility management node (20).

1. A radio communication system comprising a base station, a mobility management node, and a gateway, wherein:
said base station transmits information of origination addresses of one or more neighboring base stations of said base station to said mobility management node; said mobility management node receives the information of the origination addresses of said one or more neighboring base stations from said base station, and transmits the information of the origination addresses of said one or more neighboring base stations to said gateway; and said gateway receives the information of the origination addresses of said one or more neighboring base stations from said mobility management node; saves the information of the origination addresses of said one or more neighboring base stations; and collates an origination address of packet data transmitted to the gateway from a movement destination base station with which a radio communication apparatus has performed handover with said saved origination addresses and verifies safety of the packet data received by the gateway; and wherein when said base station becomes said movement destination base station, the base station transmits to said mobility management node the information of the origination addresses of said one or more neighboring base stations of said base station.
