摘要
TD-LTE可提供高速的数据业务,但对语音业务的支持考虑不足,在向全IP发展的过程中,就如何支持语音业务,业界提出了不同的解决方案,如VoIPonIMS,电路域话音回落(CSFB)的多模单待(CSFB),多模双待等。本文介绍了一种TD-LTE/TD-SCDMA/GSM(GPRS)单卡多模双待终端解决方案,并对此方案的技术架构、终端模式选择过程和业务过程进行了说明。
TD-LTE help us to create a wide-bandwidth wireless access networks to support high-speed data service, but there is also a hidden crisis that it cannot well support CS service. During the TD-LTE deployement to all-IP architecture, different solutions are proposed towards how to support CS service, such as VoIP on IMS, CS Fall Back （CSFB） on Multi-Mode Single-Standby, Multi-Mode Dual-Standby. This paper gives an introduction on technical solution of TD-LTE/TD-SCDMA/GSM（GPRS） Single （U）SIM Multi-Mode Dual-Standby UE. Besides we specify the technical architecture, mode selection proecedure and service processing.
