The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the presen

41、t document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under chang

43、 Release 141 Scope This document defines the Stage 2 architecture and specification for the CS Fallback and for SMS over SGs for EPS or CS Fallback and SMS over S102. The scope of this document includes the architecture enhancements for functionality to enable fallback from E-UTRAN access to UTRAN/G

44、ERAN CS domain access and to CDMA 1x RTT CS domain access, and functionality to reuse of voice and other CS-domain services (e.g. CS UDI video / LCS / USSD) by reuse of the CS domain. The functionality specified to support SMS over SGs does not trigger any CS Fallback to UTRAN/GERAN. The functionali

45、ty specified to support SMS over S102 does not trigger any CS Fallback to CDMA 1xRTT CS domain. In addition this specification includes an SMS in MME architecture option for SMS services only. This functionality does not trigger any CS Fallback and does not require SGs. The architecture enhancements

46、 to support CS fallback to CDMA 1x RTT CS domain access for UEs with single and dual receiver configurations are specified in Annex B. In this Release of the specification no mechanisms are specified to support CS Fallback to both UTRAN/GERAN and CDMA 1xRTT in the same PLMN. So, even when a UE has t

47、he capability to support both CS Fallback to UTRAN/GERAN CS domain and CS Fallback to CDMA 1xRTT CS domain in a given PLMN, the PLMN implements only one of the two. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present doc
