WCDMA系统无线接入网QoS检测方案

提出了一种适用于WCDMA系统无线接入网的QoS检测方案。该方案以RNC到NodeB传输链路上某条被测量流的时延抖动或丢包为依据，自动检测链路的速率波动和可用传输带宽，获取网络状况，通过动态的调整准入带宽，保证传输QoS和传输带宽的最大利用率。实验结果表明，通过基于此方案的动态带宽调整，传输有效性和传输利用率显著提高。

A Flow-estimation Scheme of WCDMA System Access Network

In this paper a new flow-estimation scheme for WCDMA system access network is introduced. This scheme automatically measures velocity fluctuating and available bandwidth of the network based on latency jitter or packets lost rate of a measured transmission link from RNC to NodeB,guarantees transmisiion QoS and maximal transmisiion bandwidth utilization rate by dynamically adjusting access bandwidth. According to the test result,it shows that the performance of the new flow-estimation scheme on transmisiion QoS and bandwidth utilization rate has significantly improved.
