Method and Apparatus for Inter Home Node B Handover in a Home Node B Group
First Claim
1. A method of handing over a session in a communication system comprising (i) a first wireless communications system comprising a licensed wireless radio access network and a core network and (ii) a second wireless communications system comprising a plurality of short range access points for establishing service regions of the second wireless communications system using licensed wireless frequencies and a network controller for communicatively coupling a user equipment (UE) operating in the service regions to the core network, the method comprising:
- receiving, at the network controller, a relocation required message from a first access point, the relocation required message triggered by the first access point determining to handover the UE to a second access point, wherein the UE has at least one ongoing session with the core network through the first access point, the relocation required message comprising a domain identifier for said session;
sending a relocation request message from the network controller to the second access point, the relocation request message comprising said domain identifier; and
sending a relocation command message to the first access point, the relocation command message for sending to the UE and causing the UE to handover from the first access point to the second access point, the relocation command message comprising said domain identifier.

Abstract
A method of handing over in a communication system that includes a first wireless communications system that has a core network and a second wireless communications system that includes several short range access points using licensed wireless frequencies and a network controller for communicatively coupling a user equipment to the core network. The method receives a relocation required message when a first access point determines to handover the UE to a second access point. The UE has at least one ongoing session with the core network through the first access point, the relocation required message includes a domain identifier for the session. The method sends a relocation request message including the domain identifier to the second access point. The method sends a relocation command message to the first access point for sending to the UE to handover from the first access point to the second access point.

18. A computer readable medium storing a computer program for handing over a session in a communication system comprising (i) a first wireless communications system comprising a licensed wireless radio access network and a core network and (ii) a second wireless communications system comprising a plurality of short range access points for establishing service regions of the second wireless communications system using licensed wireless frequencies and a network controller for communicatively coupling a user equipment (UE) operating in the service regions to the core network, the computer program executable by a processor, the computer program comprising sets of instructions for:
-
receiving, at the network controller, a relocation required message from a first access point, the relocation required message triggered by the first access point determining to handover the UE to a second access point, wherein the UE has at least one ongoing session with the core network through the first access point, the relocation required message comprising a domain identifier for said session; sending a relocation request message from the network controller to the second access point, the relocation request message comprising said domain identifier; and sending a relocation command message to the first access point, the relocation command message for sending to the UE and causing the UE to handover from the first access point to the second access point, the relocation command message comprising said domain identifier.
