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 in a gradual improvement stage. There are some cases of coverage of weaknesses and weaknesses in the edge of the coverage. This necessitates the introduction of 2G and 3G interoperability technologies. If the existing GSM network in the TD network coverage hole and the coverage edge area has good coverage, some 2G and 3G interoperability mechanisms may be selected so that the user can enter the GSM network system early in the early stage of the TD coverage edge and call drop, thereby avoiding Such as poor call quality, dropped calls, etc., to ensure the normal operation of users’ services and improve the user’s perception and satisfaction so as to make the GSM network an effective complement and auxiliary to the TD-SCDMA network.
