SA2 #176Final
At a glance
The register confirms approval of the KI#1.1 interim-conclusion pCR, submitted by Nokia with ten co-submitters, and the 2A2 modular-NAS update. The supplied evidence does not expose the conclusion text, and these approvals are not normative decisions.

Approved pCR text covers both embedded intent handling in other 6G CN NFs and a separate 6G CN AI domain. The register records study-TR approvals, not a choice between these approaches.

Approved ISAC pCRs add a sensing-UE mobility scenario, non-3GPP sensing data, and general 6G ISAC design text. These are study-TR approvals, not a normative architecture decision.

20.6.1Study on Architecture for 6G System (FS_6G_ARC) - support for control signalling for 6G System
The excerpts show parallel solution variants, not a recorded choice. Ericsson's item updates existing SV#1.1.1 and was not treated, which is not rejection.

|---|---|---|
| Ericsson | Ericsson's not-treated editor-note update includes existing SV#1.1.1 text on 5G-core and NAS evolution.Their wordsThe core network and NAS signalling for 6G system is proposed to be an evolution for 5G core and 5G NAS respectively. | S2-2607217paragraph 58 · register: not treated |
| Huawei (with HiSilicon, Deutsche Telekom, CATT, HONOR, vivo, ZTE, IIT Bombay, Reliance Jio, Xiaomi, ETRI, OPPO) | Huawei with co-submitters separates MM in the AMF from signalling routing in a new SRF.Their wordsIn this reference architecture, 6G MM and signalling routing functionalities are separated into different network entities: 6G MM is kept in the 6G AMF, while [...] | S2-2609158paragraph 72 · register: approved |
20.6.18Study on Architecture for 6G System (FS_6G_ARC) - AI for 6G architecture
The contributions describe a separated AI domain and AI-capable NFs handling requests without intent. The supplied evidence does not record a choice between these approaches.
| Company | What they propose | Source |
|---|---|---|
| Nokia (with NVIDIA, Federated Telecoms Hub, T-Mobile USA, AT&T, Qualcomm, Verizon, Deutsche Telekom, Turkcell, Ericsson, BT, Google) | Nokia and co-submitters describe separate 6G CN PS and AI domains.Their wordsFigure 6.18.3.1.1-1 provides an overview of the 6G CN architecture with separated 6G CN PS and 6G CN AI domains. | S2-2609044paragraph 47 · register: approved |
| Samsung | Samsung's not-treated proposal says NFs with AI capabilities may handle requests without intent.Their wordsThe 6G UE and AF are agnostic to whether specific requests without intent are handled by NFs with AI capabilities in 6G CN. | S2-2607297paragraph 11 · register: not treated |
20.6.1Study on Architecture for 6G System (FS_6G_ARC) - support for control signalling for 6G System
The contributions describe NAS signalling through an SDMF and a new interface between the UE and an intermediate NF. They do not establish a selected mechanism.

|---|---|---|
| Huawei (with HiSilicon, China Mobile, CATT, vivo) | Huawei and co-submitters describe NAS signalling between the UE and SDMF for discovery and authorization.Their wordsThe UE and the SDMF use NAS signalling to support the generic mechanism for service discovery and service authorization. | S2-2609035paragraph 65 · register: approved |
| Samsung | Samsung's solution introduces a UE-to-intermediate-NF signalling interface.Their wordsA new signalling interface between UE and the intermediate NF is introduced to enable common service authorization and discovery for operator service. | S2-2609164paragraph 29 · register: approved |

Coverage: SA2 #176 (Prague, 2026-08-24 to 2026-08-28), agenda items 20.6.1, 20.6.18, 20.6.20.
Scout read 38 recorded decisions and 141 company positions or contribution passages on these agenda items (catalog synced 2026-09-29) and cites 15 decisions and 6 positions from 19 TDocs. Every quoted passage was matched verbatim against the TDoc text; the summaries around the quotes are Scout's reading. Register statuses are copied from the 3GPP TDoc register: not treated means a document was not handled on its own, though its content may have fed feature-lead summaries or merged revisions. Not covered: other agenda items and meetings, plenary TDocs and plenary decisions after the meeting, email discussions after the meeting, and anything not yet in the chair notes or register.
The supplied decision items are register records, not chair or session reports.
Register evidence confirms pCR approval into the study TR, not normative decisions.
Company inputs marked not treated are pre-meeting proposals, not evidence of meeting discussion.
