23.272 | Circuit Switched (CS) fallback in Evolved Packet System (EPS); Stage 2 | TS | 18.0.0 | S2 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.272/23272-i00.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. |

Specifically, two objectives are included:
WT#2: Investigate whether traffic steering policy is sufficient to support SA WG1 requirements in TS 22.101 [5], TS 22.261 [6] and TS 22.115 [7], study whether and how to define Service Function Chaining (SFC) policies, and investigate solutions and procedures for the 5G network with SFC capabilities to identify/detect/classify user plane traffic and steer the traffic to a chain of ordered service functions for SFC processing in non-roaming and home routed roaming scenarios.
WT#3: Depending on the outcome of WT#2, specify possible enhancement to northbound APIs for allowing an AF to request network capability exposure functionalities, e.g. request a service function chain for a certain traffic flow, etc. based on service level agreement with the third party.
NOTE 1: This study considers only traffic handled over N6 by PSA UPF(s) in 5G network.
NOTE 2: The definition of terms in RFC 7665 [8] may be re-used when applicable. The study targets the use of traffic steering concept, e.g. defined by 3GPP (FMSS) and SFC mechanisms defined in IETF when applicable. Especially the study aims at reusing user plane mechanisms (e.g. VXLAN, NSH, GENEVE, GRE, VLAN, etc.) defined at IETF to support SFC, as applicable.
NOTE 3: The study for SFC will ensure that existing (per 3GPP Rel-17) deployments flexibility can be preserved in deployments of SFC in 5G network.
NOTE 4: The study assumes a Home Routed roaming PDU Session does not have an offloading point in a VPLMN. |

The following aspects are covered:
- Study how to report 5GS network timing synchronization status (such as divergence from UTC and 5GS network timing source degradation) to UEs and 3rd party applications (AFs):
- Study how RAN and 5GC learn about network 5GS network timing synchronization status to be able to inform UEs and AFs.
- Study if additional information needs to be provided to UEs and AFs to inform about 5GS network timing synchronization status.
- Study how to enable AFs to request time synchronization service in a specific coverage area and how to enforce the coverage area.
- Study how to control 5G time synchronization service based on subscription (i.e. introducing subscription parameter for time synchronization and enforcing it).
- Study how to enable an AF to explicitly provide PER to NEF/PCF.
- Study mechanisms for interworking with TSN transport networks. Study interworking mechanisms with TSN networks deployed in the transport network in order to support of E2E determinism and low latency communication and efficient N3 transmission.
- Study if there is a need for applications to adapt downstream scheduling in order for 5GS to meet really low latency (e.g. 2 msecs) requirement and if there is a need to have feedback from RAN (e.g. for application to consider DL packet transmission time slots to avoid buffering in the RAN) for this purpose. |

1: Architecture enhancements for support of a backhaul with changing delay (e.g. brought by ISL in satellite networks or changed satellite backhaul on the UP path), and possibly limited bandwidth in case of a gNB with satellite backhaul only (e.g. restricted by the maximum data rate of a satellite beam):
- Policy/QoS control enhancements based on the detected packet delivery latency and/or bandwidth of the satellite backhaul on the UP path;
- Exposure of backhaul information to AFs.
2: Architecture enhancements for support of UPF deployed on GEO satellite with gNB on the ground:
- Whether and how to enable satellite edge computing services via UPF on-board e.g. to reduce the latency for data transmission, and minimize the backhaul resources consumption.
- How to enhance local switch for UEs in a communication when they are served by UPF on-board, e.g. to reduce end to end delay comparing with existing 5G LAN local switch at PSA on the ground. |

3. Study whether and how to support the following stage one Rel-18 EASNS requirements related to roaming specified in TS 22.261 clause 6.1.2.1, i.e. Requirement on enhancement the information available to the UE in roaming scenarios regarding the availability of network slices in VPLMNs available in the roaming country, in order to allow the UE to select and obtain services from the VPLMN supporting the network slices which UE may wish to use.
4. Study whether and how to enhance the system to ensure network controlled behaviour of network slice usage including UE registration and PDU Session establishment (e.g. so that when performing NSAC the network slice can serve UEs/PDU Sessions with actual activity).
5 Study deployment considerations when a service provided has an area of service that does not overlap with the already deployed Tracking Areas and/or have a limited lifetime and how existing mechanisms including network slicing can help support such scenarios. If existing mechanisms are concluded to be not sufficient to achieve the scenarios, study whether and how additional mechanisms can resolve the analysed gap.

23.700-53 | Study on access traffic steering, switching and splitting support in the 5G system architecture; Phase 3 | TR | 18.0.0 | S2 | https://www.3gpp.org/ftp/Specs/archive/23_series/23.700-53/23700-53-i00.zip | The purpose of this Technical Report is to enhance the ATSSS feature by investigating solutions that can support the following capabilities:
1) Support new steering functionalities that can steer/switch/split non-TCP traffic flows (e.g. UDP traffic flows and IP traffic flows). Two types of such steering functionalities are studied: (i) a steering functionality based on the QUIC protocol and its multipath extensions, and (ii) a steering functionality based on the DCCP protocol and its multipath extensions.
2) Support redundant traffic steering for both GBR and non-GBR traffic flows. With redundant traffic steering, a traffic flow (GBR or non-GBR) can be replicated on multiple access paths and, therefore, can improve transmission reliability and reduce packet latency.
3) Support traffic switching between one non-3GPP access path, from a UE to a N3IWF in a PLMN, and another non-3GPP access path, from the UE to a TNGF in the same PLMN.
4) Support the establishment of a MA PDU Session with one 3GPP access path via 5GC and one non-3GPP access path via ePDG/EPC. This is to complement the existing ATSSS capability that supports the establishment of a MA PDU Session with one non-3GPP access path via 5GC and one 3GPP access path via EPC.
For each of the above capabilities, the conclusions of the study identify whether a solution is required for the normative phase and, if required, which solution to consider in the normative phase. |
