1. 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.

1. 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. - View Dependent Claims (2, 3, 4, 5, 6)

7. A system for controlling handover of a user terminal device, comprising:
- a source Evolved NodeB (eNB), a Home Evolved NodeB Gateway (HeNB GW) and a target eNB;
whereinthe source eNB is configured to send a handover request of a User Equipment (UE), on which handover needs to be performed, to the HeNB GW and receive a handover request acknowledgement message sent from the HeNB GW; the HeNB GW is configured to receive the handover request of the UE sent from the source eNB, send a requesting message for obtaining a UE context to an Mobility Management Entity (MME), the requesting message carrying an MME UE S1 AP ID and an eNB UE S1 AP ID of the UE, and receive 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, convert the handover request into a handover request which satisfies an interface form between the HeNB GW and the target eNB, send the converted the handover request to the target eNB, and receive the handover request acknowledgement message sent from the target eNB, convert 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 send the converted the handover request acknowledgement message to the source eNB; and the target eNB is configured to receive the handover request which satisfies the interface form between the HeNB GW and the target eNB sent from the HeNB GW, and send the handover request acknowledgement message to the HeNB GW if the target eNB permits the UE to access the target eNB. - View Dependent Claims (8, 9)
- a source Evolved NodeB (eNB), a Home Evolved NodeB Gateway (HeNB GW) and a target eNB;

10. A Home Evolved NodeB Gateway (HeNB GW), comprising a receiving module, a constructing module and a sending module;
- wherein
the receiving module is configured to receive a handover request of a User Equipment (UE), on which handover needs to be performed sent from a source Evolved NodeB (eNB), and a handover request acknowledgement message sent from a target eNB, and receive a response message from an Mobility Management Entity (MME), wherein the response message carrying an MME UE S1 AP ID, an eNB UE S1 AP ID, and a UE context; the constructing module is configured to construct a handover request which satisfies an interface form between the HeNB GW and the target eNB according to the handover request of the UE sent from the source eNB, and construct a handover request acknowledgement message which satisfies an interface form between the source eNB and the HeNB GW according to the handover request acknowledgement message sent from the target eNB; and the sending module is configured to send a requesting message for obtaining the UE context to the MME, the requesting message carrying the MME UE S1 AP ID and the eNB UE S1 AP ID of the UE, send the handover request which satisfies the interface form between the HeNB GW and the target eNB to the target eNB, and send the handover request acknowledgement message which satisfies the interface form between the source eNB and the HeNB GW to the source eNB.
