RADIO COMMUNICATION SYSTEM, RADIO BASE STATION AND COMMUNICATION METHOD

摘要

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 eNB 100 sends a handover request which requests an inter base-station handover of a UE 50 from the eNB 100 to an eNB 200 via an inter base-station transmission path. The eNB 200 receives the handover request from the eNB 100, and completes the handover of the UE 50 from the eNB 100 to the eNB 200 by using a communication path to the UE 50 via a highway between an MME 20 and the eNB 100 and the inter base-station transmission path.

主权项

1. A radio communication system comprising:
a first radio base station connected to a higher-level station via a first transmission path; and a second radio base station connected to the higher-level station via a second transmission path and connected to the first radio base station via an inter base-station transmission path, wherein the first radio base station includes a handover request unit configured to transmit a handover request which requests an inter base-station handover of a mobile station from the first radio base station to the second radio base station via the inter base-station transmission path, and the second radio base station includes:
a handover request reception unit configured to receive the handover request from the first radio base station; anda handover execution unit configured to, when the handover request reception unit receives the handover request, complete the handover of the mobile station from the first radio base station to the second radio base station by using a communication path to the mobile station via the first transmission path and the inter base-station transmission path.
