当前移动通信发展迅速,无线移动通信向4G演进已成为移动通信演进的主要趋势。而4G目前只提供数据上网业务,语音业务需回落到3G完成。为了解决LTE/WCDMA发展覆盖不均衡的问题,通过对比4G单独组网及3/4G综合组网可行性分析,达到解决LTE语音回落的问题,为后续4G单独投资提供思路及参考作用。
The current rapid development of mobile communications, wireless mobile communications to 4G evolution has become the main trend of mobile communications. 4G currently only provides data access services, voice services need to fall back to 3G to complete. In order to solve the problem of unbalanced coverage of LTE / WCDMA development, we can solve the problem of LTE voice drop by comparing the feasibility of 4G stand-alone networking and 3 / 4G comprehensive networking to provide ideas and reference for the subsequent 4G separate investment.
