TD-SCDMA网络2G、3G互操作优化探讨

Exploration on Interoperability Optimization of TD-SCDMA and GSM Networks

TD-SCDMA网络正处在逐步完善的阶段,存在一些覆盖空洞和覆盖边缘弱场强情况,这就必须引进2G、3G互操作的技术。若在TD网络覆盖空洞和覆盖边缘区域中现有的GSM网络覆盖良好,则可选择一些2G、3G互操作机制,使用户在TD覆盖边缘和掉话的前期尽早进入GSM网络系统中,从而避免出现通话质量差、掉话等现象,保障用户各项业务的正常进行,提高用户感知度和满意度,从而使GSM网络成为TD-SCDMA网络的有效补充和辅助手段。

TD-SCDMA network is now in a stage of gradual perfection,and there are some coverage holes and the weak field-strength areas,so it is necessary to introduce the interoperability of 2G and 3G technologies.If the existing GSM network has a good coverage on TD-SCDMA network coverage holes and the weak field-strength areas,then the interoperability mechanism may be chosen,thus enabling users to enter the GSM network before the call dropping and avoiding poor call quality,and guaranteeing the normal conduction of various businesses,these could improve the user＇s perception and satisfaction,so that the GSM network may become an effective complement and auxiliarly means of TD-SCDMA network.
