Embodiment Construction

[0063] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0064] The embodiment of the present invention can be applied to the X2 handover process. In a specific implementation, the X2 handover process can include the following process:

[0065] 1: The source eNode B (Evolved Node B, evolved Node B, the name of the base station in LTE, that is, the source base station referred to later in the embodiment of the present invention) performs measurement configuration on the UE (User Equipment, user equipment), and the measurement result of the UE will be It is used to assist the source eNode B in handover decision.

[0066] 2: The UE reports the measurement according to the measurement configuration.

[0067] 3: The source eNode B makes a handover decision according to its own handover algo...

Abstract

The embodiment of the invention provides a forward data processing method and device. The method comprises the following steps: determining whether a forward message to be sent to a target base station is a transmission control protocol TCP proxy message or not; if the forwarding message is a TCP proxy message, adding a user plane tunnel terminal identifier (TEID) of a source base station into theforwarding message to generate a target forwarding message; and sending the target forwarding message to a target base station side. The TEID of the source base station side is carried to the targetbase station side, the target base station can conveniently return ACK for the TCP proxy message, and reliable forwarding of TCP proxy data is realized.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for processing forwarded data and a device for processing forwarded data. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) data transmission network, the TCP (Transmission Control Protocol) protocol is mainly used to complete the transmission of data services, and the current LTE wireless network data processing mechanism includes maximum retransmission, RLC (Radio Link Control, a radio link control layer protocol in a wireless communication system) sends data in sequence, etc. Since the TCP protocol is based on a wired network protocol, it does not consider wireless features. In order not to discard data, the wireless side uses the maximum retransmission, which will cause the timeout of the TCP layer, which will cause the TCP transmission delay to increase. The long transmission delay will cause low download rate and ...
