基于用户感知的WCDMA无线资源效能评估方法研究

摘要

It analyzes current network data, and concludes that the increasing of smal traffic service brings the increasing of RRC con-necting time, the consumption of function resource also increased. Data service re-transmitting impacts on resource efficien-cy, the higher the re-transmitting rate, the lower the power efficiency. Based on the above, it presents new WCDMA radio re-source utilization rate calculation method to increase the impacts of signal ing overhead and data re-transmitting. Final y, it ana-lyzes the relation of user rate, radio resource utilization rate and user number, to provide suggestions on WCDMA network sim-ple extension standards.%通过现网采集数据分析，研究得出由于小流量业务占比增长带来的RRC连接次数的增加，其对功率资源的消耗相应增加；另外，数据业务重传直接影响资源效率，重传率越高，功率效率越低，基于此，提出新的WCDMA无线资源利用率计算方法，在原计算方法基础上增加了信令开销和数据重传的影响。最后，根据现网用户对典型业务的速率感知需求，分析用户速率和无线资源利用率、用户数的关系，为WCDMA网络简单扩容标准给出建议。
