Abstract

This invention discloses a method to avoid repeatedly sending automatically resending data. When UE conducts switching and source base station transmits data to the target one, UE or source base station also need to provide the data receiving state and / or paragraphing information of UE. According to it, the target base station determines whether the state of receiving paragraphing data is right, and only resends those data that gets negative response of UE, which is not correctly received by UE, and sends data never transmitted, avoiding resending the received data and saving resources effectively.

Description

technical field

[0001] The present invention relates to handover technology, in particular to a processing method for avoiding repeated transmission of Automatic Repeat reQuest (ARQ, Automatic Repeat reQuest) data after handover. Background technique

[0002] The 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) is studying network evolution in order to enhance the competitiveness of future networks. The evolved 3G network should have the technical characteristics of high speed, low delay, and IP. In order to achieve this goal, in the field of Radio Access Network (RAN, Radio Access Network) research, a series of related technical issues including mobility management must be solved. The handover in the 3G network needs to be researched and described from two aspects of the control plane (CP, Control Plane) and the user plane (UP, User Plane). From the perspective of the handover process, the handover can be divided into three stages: preparation,...
