GSM网络无线利用率提升思路研究

Research on raising wireless utilization rate of GSM network

随着LTE网络发展,VoLTE话务持续迁转,GSM语音话务量和语音业务占比持续走低。同时,运营商将在GSM 900MHz频段上部署FDD和NB-IoT网络,900MHz频段将出现GSM、FDD LTE、NB-IoT共存的局面,频率资源进一步紧张。本文研究了GSM网络无线利用率提升思路,通过实现GSM网络资源利用率有效提升,为载频压降及频率压缩提供空间,为后续网络平稳演进做好准备。

With the development of LTE network,VoLTE traffi c continues to transfer,and the proportion of voice traffic and voice service in GSM continues to decline.At the same time,operators have successively completed FDD and NB-IoT network deployment in the GSM 900MHz band,and the 900MHz band has witnessed the coexistence of GSM,FDD LTE and NB-IoT,resulting in further shortage of frequency resources.This paper studies the ways of improving the wireless utilization rate of GSM network.By effectively improving the utilization rate of GSM network resources,it provides space for the carrier frequency voltage drop and frequency compression of the existing network,and prepares for the smooth evolution of the subsequent network.
