Abstract
A target node includes an S1 interface which includes an interface between the target node and a gateway, an X2 interface which includes an interface between a source node and the target node, and a transceiver which receives data from the S1 interface and data from the X2 interface. The transceiver sends the data from the X2 interface before sending the data from the S1 interface to a mobile device after the mobile device completes a handover from the source node to the target node.
Claims2
A communication control method for a target eNB, the communication control method comprising:
- receiving data from a gateway over an S1 interface and receiving data forwarded over an X2 interface, wherein the S1 interface is an interface between the target eNB and the gateway and the X2 interface is an interface between a source eNB and the target eNB;
- transmitting, for a radio link control acknowledge mode bearer, to a user equipment (UE), downlink data from the X2 interface with the exception of data of which reception was acknowledged by the UE;
- and
- sending, after transmitting the downlink data from the X2 interface, downlink data from the S1 interface.

A target eNB comprising:
- a receiver configured to receive data from a gateway over an S1 interface and to receive data forwarded over an X2 interface, wherein the S1 interface is an interface between the target eNB and the gateway and the X2 interface is an interface between a source eNB and the target eNB;
- and
- a transmitter configured:
- to transmit, for a radio link control acknowledge mode bearer, to a user equipment (UE), downlink data from the X2 interface with the exception of data of which reception was acknowledged by the UE, and
- to send, after transmitting the downlink data from the X2 interface, downlink data from the S1 interface.
