共享网络和GSM/GPRS/WCDMA无缝网络——3G网络建设两大趋势

Common Shared Network and Seamless Network of GSM/GPRS /WCDMA

市场形势的变化决定着移动运营商的经营战略,当前在3G的建设中呈现两大趋势:共享网络和双模无缝网络。在建网初期,通过与GSM共用核心网,运营商可以有选择地建立WCDMA覆盖,在双模手机的支持下,通过切换技术,无缝地、透明地为用户提供多种语音和数据业务。而通过与其他运营商共享网络,可以实现快速覆盖,快速启动和运营业务,而且可以在完全保护已有投资的基础上逐步过渡到自己独立的网络。

The change in market situation de cides the operation strategy of mobile op era tors.There are two major trends in the con struction of3G:common shared network and du al -mode seamless network.During the ini tial stage of the network con struction,through sharing core network with GSM,operators can selectively establish WCD MA coverage,to seamlessly and transparently provide users with voice and data services with the sup port of dual -mode mo bile phone,through handover tech nology,While through sharing network with oth er op erators,they can realize rapid coverage,rapid start and service operation.Networks can be transit ed to their own independent networks on the basis of full protection of existed investment.
