LTE网络CSFB语音业务干扰优化分析

Optimization Analysis of CSFB Voice Interference in LTE Network

干扰问题一直是移动通信网络优化的核心问题之一,尤其是现行的网络结构中多种制式并存和融合的情况下,不同的系统之间也存在着干扰和被干扰的关系。除了无线网络内部的干扰问题外,移动通信网络还面临着外部复杂多变的无线信号源的侵扰。且移动用户的增长以及部分基站设备老化都给移动通信系统的稳定性带来了巨大的挑战。因此,有必要根据CSFB语音业务系统设备本身和组网的特点进行分析,找到产生干扰的原因,从而指导CSFB语音业务干扰的优化工作。

Interference problem has always been the core problem of mobile communication network optimization,especially in the current network structure, many systems coexist and merge, there are also interference and interference relationships between different systems. In addition to interference problems inside wireless networks, they also face intrusion of external complex and variable wireless signal sources. And with the growth of mobile users, coupled with the aging of some base station equipment, it brings great challenges to the stability of mobile communication systems.Therefore, it is necessary to analyze the CSFB voice business system itself and the characteristics of networking, locate the cause of interference, so as to guide the optimization of CSFB voice service interference.
