application example 1

[0057] This application example is based on the following application scenario: the RLC wireless parameters of the data sending end (eNodeB) configured on the control plane of the network side are polling timer t_PollRetransmit duration of 50ms, pollByte of 5000 bytes, pollPDU of 32, and the maximum number of retransmissions maxRetxThreshold The threshold value is 3 times; the configured data receiving end (UE) RLC wireless parameters are the reordering timer t_Reordering duration of 50ms, and the status prohibition timer t_statusProhibit duration of 100ms.

[0058] Among them, the above wireless parameter function is described as follows:

[0059] t_PollRetransmit: polling timer, one of the sending conditions of the polling message at the sending end, once the timer expires, the sending end thinks that it can send a data message with the polling position 1, and requires the receiving end to give the message received before If there is no new message to send at this time, the ...

application example 2

[0074] The wireless parameters of the sender (eNodeB) RLC protocol entity configured on the control plane of the network side are the polling timer t_PollRetransmit timer duration is 100ms, pollPdu is 5000 bytes, pollPDU is 256, and the maximum number of retransmissions maxRetxThreshold is 4 times; configure The radio parameters of the receiving end (UE) RLC protocol entity are that the duration of the reordering timer t_Reordering timer is 50ms, and the duration of the status prohibition timer t_StatusProhibit timer is 20ms.

[0075] In this embodiment, the parameter configuration is reasonable, the receiving end can quickly send back a response, and the sending end does not send polling messages frequently.

[0076] The execution process of this application example is as follows image 3 As shown, it mainly includes the following steps:

[0077] Step 201. The RLC protocol entities at the sending end of the network side of DRB1 and DRB2 both detect that the number of retrans...

Abstract

The invention discloses a method and a system for processing message exception of a network side wireless link control layer. The method comprises the following steps of: when a network control plane discovers an exception that message retransmission times exceeds the maximum retransmission times on a signaling / data wireless borne network transmitting end RLC protocol entity of user equipment UE, judging whether the UE has executed the wireless parameter reallocation process due to the exception, if so, initiating the intracell switching process for the UE, otherwise, initiating the wireless parameter reallocation process for the UE. Compared with the prior art, the method solves the problem of the exception that the retransmission times exceeds the maximum retransmission times on the network side, avoids poor user experience caused by releasing the service or the whole UE, and ensures the sustainability and quality of the service.

Description

technical field [0001] The present invention relates to the field of communications, and more specifically, to a method and system for processing abnormality of radio link control layer messages on the network side in an LTE (Long Term Evolution, long-term evolution) system. Background technique [0002] The RLC (Radio Link Control, radio link control) protocol layer is a sublayer of layer 2 (L2) in the wireless interface protocol stack of LTE, and is located above the MAC (Media Access Control, media access control) layer. The RLC protocol layer is used to provide 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 the RRC (Radio Resource Control, radio resource control) protocol and operates in three modes, namely: transparent ...
