Gateway apparatus, communication control method, and non-transitory computer readable medium storing communication control program
First Claim
1. A mobile communication system comprising:
- a Home Node B-Gateway (HNB-GW);
a source Home Node B (HNB) which transmits, to the HNB-GW, a Direct Transfer message which includes a Target RNC-ID and a Target Cell ID;
a target HNB; and
a mobile station which receives, from the source HNB, a channel reconfiguration message, and synchronizes with the target HNB, and transmits, to the target HNB, a channel reconfiguration complete message,wherein the HNB-GW constructs RANAP relocation required message using the Target RNC-ID and transmits the RANAP relocation required message to the target HNB and detects a relocation from the source HNB to the target HNB, after received the Direct Transfer message from the source HNB, andwherein the HNB-GW transmits the RANAP relocation required message to the target HNB, when the Target RNC-ID received from the source HNB is same as a RNC-ID allocated by the HNB-GW.

Abstract
A gateway apparatus is disposed between base stations and a core network, and includes receiving and transmitting units. The receiving units receives in response to the start of a location change of a mobile station from a cell managed by a base station to another cell, a location change message including a transfer destination identifier indicating a base station control apparatus associated with another base station managing the another cell. The transmitting unit determines whether to transmit the message to one of the base stations or to the core network based on whether the transfer destination identifier matches an identifier of a base station control apparatus, and accordingly transmits the message.
