Method for monitoring quality of down wireless link over network

Abstract

The invention discloses a method for monitoring wireless link quality at network side. It includes the following steps: judging the transferring mode of current descendent wireless link at RLC layer by wireless resource managing module and taking monitoring to the BLER to the current descendent wireless link; when the current wireless link at the transferring mode of RLC layer is in affirming mode, the RLC layer accounting and send descendent wireless link BLER value. The invention realizes real time monitoring descendent wireless link and reasonably distributes wireless resource. The invention could gain high accuracy and save network resource and wireless resource.

Description

technical field [0001] The invention relates to the technical field of wireless network communication, in particular to a method for monitoring the quality of downlink wireless links at the network side. Background technique [0002] On the network side of the WCDMA system, there is a wireless resource management algorithm module, which is responsible for managing the management of the access resources of the entire wireless access side, including code resources, power resources, link quality, etc. [0003] Among them, the communication quality of the wireless link is measured by BLER (Block Error Rate). Timely and accurate monitoring of BLER can take targeted measures on the network side to prevent call drop, improve communication quality, and improve user satisfaction. [0004] For the uplink, the current BLER value can be easily and accurately obtained in time. Because the outer loop power control module of the sub-module of the radio resource management module can coun...

AI Technical Summary

Problems solved by technology

If the current wireless environment is relatively poor, the downlink wireless link cannot receive data packets at all, that is to say, the mobile terminal cannot demodulate any data packet information at all. In this case, the mobile terminal cannot perform statistics on the actual value of BLER, resulting in BLER inaccurate value;

[0011] 3. Since the mobile terminal adopts the method of periodic reporting, there is a large amount of message interaction between the mobile terminal and the network side, which causes a great waste of mobile resources, network resources, and wireless resources
