1. A handover processing method, comprising:
- receiving, by a controller, a first handover trigger message sent by a first network element node with respect to handing over a user equipment (UE) from the first network element node; and
sending, by the controller a second handover trigger message to a second network element node according to the first handover trigger message and in response to the receiving the first handover trigger message, to thereby cause the second network element node to hand over user the UE from the first network element node to the second network element node according to the second handover trigger message, wherein;
the first handover trigger message is a handover request message;
the receiving a first handover trigger message sent by a first network element node comprises;
receiving the handover request message sent by the first network element node; and
after the receiving the handover request message sent by the first network element node, the method comprises sending a stop command message to the first network element node, to thereby cause the first network element node to stop scheduling for the UE by stopping performing resource configuration for the UE.

Abstract
A handover processing method, apparatus, and system include: receiving a first handover trigger message sent by a first network element node; and sending a second handover trigger message to a second network element node according to the first handover trigger message, so that the second network element node hands over user equipment UE from the first network element node to the second network element node according to the second handover trigger message. Handover between small cells or between a small cell and a macro cell is implemented, and because a controller is used to perform handover, a handover delay is effectively reduced, and network performance is improved.

5. A controller, comprising:
-
a receiver, configured to receive a first handover trigger message sent by a first network element node with respect to handing over a user equipment (UE) from the first network element node; and a transmitter, configured to send a second handover trigger message to a second network element node according to the first handover trigger message and in response to the receiving the first handover trigger message, to thereby cause the second network element node to hand over the UE from the first network element node to the second network element node according to the second handover trigger message, wherein; the first handover trigger message is a handover request message; the receiver is configured to receive the handover request message sent by the first network element node; and the transmitter is further configured to, after the receiver receives the handover request message sent by the first network element node, send a stop command message to the first network element node, to thereby cause the first network element node to stop scheduling for the UE by stopping performing resource configuration for the UE. - View Dependent Claims (6, 7, 8, 9)

10. A first network element node, comprising:
-
a receiver, configured to receive a measurement report sent by user equipment (UE); and a transmitter, configured to send a first handover trigger message to a controller according to the measurement report, to thereby cause the controller to send a second handover trigger message to a second network element node according to the first handover trigger message and in response to the controller receiving the first handover trigger message, to thereby cause the second network element node to hand over the UE from the first network element node to the second network element node, wherein the receiver is further configured to, after the transmitter sends the first handover trigger message to the controller according to the measurement report, receive a stop command message sent by the controller, and stop scheduling for the UE according to the stop command message by stopping performing resource configuration for the UE. - View Dependent Claims (11, 12, 13, 14, 15)
