Patent ID: 8588182

Claim:
A method for controlling handover of a user terminal device, comprising: receiving, by a Home Evolved NodeB Gateway (HeNB GW), a handover request of a User Equipment (UE), on which handover needs to be performed, sent from a source eNB, sending, by the HeNB GW, a requesting message for obtaining a UE context to an Mobility Management Entity (MME), the requesting message carrying an MME UE S1 Application Protocol (AP) ID and an eNB UE S1 AP ID of the UE, and receiving a response message from the MME, wherein the response message carries the MME UE S1 AP ID, eNB UE S1 AP ID, and the UE context, converting the handover request into a handover request which satisfies an interface form between the HeNB GW and a target eNB, and sending the converted handover request to the target eNB; receiving, by the HeNB GW, a handover request acknowledgement message sent from the target eNB if the target eNB permits the UE to access the target eNB; and receiving, by the HeNB GW, the handover request acknowledgement message sent from the target eNB, converting the handover request acknowledgement message into a handover request acknowledgement message which satisfies an interface form between the source eNB and the HeNB GW, and sending the converted handover request acknowledgement message to the source eNB.
