Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.

[0047] image 3 It is a schematic diagram of the logical structure of the system of the present invention, including two parts, the UE end and the eNodeB end, and the protocol layer relationship and module composition of the two ends are basically the same. Both ends include a control plane processing unit and a user plane processing unit. Each UE has a corresponding user plane processing unit on the eNodeB side, which is used to process user plane data belonging to the same UE. The RLC entity in the user plane processing unit is used to complete the radio link control layer protocol function. Each end may include multiple service logical channels, so there will be multiple RLC protocol entities corresponding to the service logical chann...

Abstract

The present invention provides a method and a system for reducing redundant message retransmission in the Radio Link Control (RLC) layer, which are utilized for solve the technical problem of air interface resource waste caused by repeatedly transmitting the redundant message that the receiving end has acknowledged after RLC protocol entity reestablishment. Before the RLC protocol entity receives a reestablishment instruction, every Data Radio Bear (DRB) belonging to the User Equipment (UE) attempts to send a status report to the transmitting end. The transmitting end deletes the messages that have been acknowledged before receiving a reestablishment request and does not retransmit these messages any more after reestablishment is completed to reduce the redundant message retransmission.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to an LTE (Long Term Evolution, long-term evolution) system, in the re-establishment procedure (Re-establishment procedure) of the wireless link control layer protocol entity, reducing or avoiding the retransmission of redundant messages on the sending side The method and system of the text. Background technique [0002] The RLC (Radio Link Control, Radio Link Control) protocol layer is a sublayer of L2 (Layer 2) in the wireless interface protocol stack of LTE, and is located above the MAC (Media Access Control, Media Access Control) layer. RLC The protocol layer provides segmentation and retransmission services for user and control data. The functions of the RLC protocol layer include link control, encapsulation and reassembly, concatenation, user data transmission, error correction, protocol error detection and repair, etc. Each RLC protocol entity is configured by RR...
