Patent ID: 8670764

Claim:
A method for processing messages in a wireless communication system including a femto network, a gateway, a core network (CN) and a macro network, wherein the gateway is located between the femto network and the core network, the femto network comprises at least one Home NodeB and the macro network comprises at least one serving base station, the method comprising: receiving a handover request from the Home NodeB or a server of the core network during two mobile devices are communication with each other; when the handover request is received from the Home NodeB, transmitting, by the gateway, a call setup request to the core network to set up a first call path between the gateway and the core network according to the handover request, transmitting the handover request to the core network to obtain a second call path which is a call path from the core network to the macro network and directing the server to perform the handover request according to the first call path and the second call path; and when the handover request is received from the server of the core network, moving a first mobile device of two mobile devices from the macro network to the femto network according to the handover request and activating, by the gateway, a resource modification procedure to modify call resources such that the two mobile devices are in communication with each other based on a call path from the femto network to the gateway without communicating through the core network.
