摘要：A heterogeneous communication system of performing a handover from aWiMAX communication system to a LTE communication system includes a UE adapted torequest a handover connection establishment to the LTE communication system whilereceiving a CS service from the WiMAX communication system, request an authenticationto the first WiMAX system, preferentially perform the handover to the LTE

communication system, and switch to the LTE communication system in response to ahandover message; and a GANC adapted to deliver the request of the handover

connection establishment to the LTE communication system, notify the procedure of theauthentication to the LTE communication system and provide the handover commandmessage to the UE to switch to the LTE communication system, thereby providing the CSservice to the UE through the LTE communication system. A handover from an LTEcommunication system to a WiMAX communication system is also disclosed.
