移动网络发展至今,即将进入LTE高速网络时代,各种各样的业务应用在显著提升终端用户体验的同时,也对包括“GSM、TD-SCDMA、WLAN”在内的基础网络能力提出了越来越高的要求,未来如何实现各种网络的均衡协调发展是移动运营商亟待解决的问题。本文分析了GSM(Global System for Mobile Communications)、TD-SCDMA(Time Division-Synchronous Code Division Multiple Access)、WLAN(Wireless Local Area Network)、TD-LTE(Time Division Long Term Evolution),简称“TD-LTE”)网络的特点,并对“四网协同”涉及到的关键技术经行了探讨。
With the advent of mobile networks and the upcoming entry into the LTE high-speed network era, a variety of business applications have significantly improved the end-user experience as well as the basic network capabilities including “GSM, TD-SCDMA and WLAN” Higher and higher requirements, how to achieve balanced and coordinated development of various networks in the future is a problem to be solved urgently by mobile operators. In this paper, we analyze GSM (Global System for Mobile Communications), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), WLAN (Wireless Local Area Network), TD-LTE (Time Division Long Term Evolution) LTE “) network characteristics, and ” four network cooperation "related to the key technologies discussed.
