Patent number: 10299170Abstract: A source Home Node B (HNB) of a mobile communication system transmits, to a Home Node B-Gateway (HNB-GW) of the mobile communication system, a Direct Transfer message including a Target Radio Network Controller (RNC)-ID and a Target Cell ID. A mobile station receives a channel reconfiguration message from the source HNB, synchronizes with the target HNB, and transmits a channel reconfiguration complete message to the target HNB. The HNB-GW constructs a RANAP relocation request message using the Target RNC-ID. The HNB-GW transmits the RANAP relocation request message to the target HNB, and detects a relocation from the source HNB to the target HNB, after receiving the Direct Transfer message from the source HNB.Type: GrantFiled: November 27, 2017Date of Patent: May 21, 2019Assignee: NEC CORPORATIONInventor: Kenji Kawaguchi
