Abstract

Provided are a radio communication system, a radio base station and a communication method which enable an inter base-station handover while reducing a processing load on a core network. An eNBsends a handover request which requests an inter base-station handover of a UEfrom the eNBto an eNBvia an inter base-station transmission path. The eNBreceives the handover request from the eNB, and completes the handover of the UEfrom the eNBto the eNBby using a communication path to the UEvia a highway between an MMEand the eNBand the inter base-station transmission path.
