摘要
在国内2G频谱资源被重新分配,网络配置不断压降的背景下,2G网络物联网用户数不降反升。为缓解2G网络承载压力,需不断探索数据业务参数配置策略进行专题优化。数据分析表明,物联网业务数据传输具备数据分组小和稀疏两个特点。按移动终端能力等级分配信道资源和通过状态维护定时器预留信道资源的机制在此业务特征下略显冗余且造成资源浪费。本文在这两个方向上进行了理论分析和优化实践,通过设置网络参数可在保持语音和数据业务质量稳定的前提下,显著提升PDCH承载效率,降低PDCH占用时长。
Under the background of the redistribution of domestic 2G spectrum resources and the continuous pressure drop of network configuration,the number of 2G network Internet of things users has not decreased but has risen.In order to alleviate the pressure of 2G networks resource,it is necessary to continuously explore the confi guration strategy of data service parameters.Data analysis shows that the characteristics of IoT service data transmission are extremely prominent,packet is small and sparse;the mechanism of resources allocating is slightly redundant and wastes resources under this service feature.This paper makes theoretical analysis and optimization practice in these two directions.The targeted setting of network parameters can significantly improve the PDCH bearing efficiency and reduce the PDCH occupation time under the premise of maintaining the stable quality of voice and data services.
