23.272 | Circuit Switched (CS) fallback in Evolved Packet System (EPS); Stage 2 | TS | 19.1.0 | S2 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.272/23272-j10.zip | 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/GERAN 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 functionality 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 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 the 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. |

NOTE 1: The mobile gNB configuration aspect needs synchronization with RAN working group.
NOTE 2: No enhancement is aimed to the existing QoS mechanisms for the wireless backhaul. |

In this study, the user to be identified could be an individual human user using a UE with a certain subscription or a device behind a gateway UE or 5G-RG.
Use cases are discussed in clause 26a of TS 22.101 [2] and include:
- an individual human user, using a UE with a certain subscription; and
- a device ("thing") behind a gateway UE.
Requirements related to the collection of charging information for users are specified in clause 5.2.17 of TS 22.115 [3].
NOTE: Charging is in the remit of SA WG5. |
