Update on 3GPP Activity for 5G Networks
This document provides an update on the recent activities of 3GPP, focusing on the progress in 5G network development. It covers key technical specifications, such as non-3GPP access procedures and service requirements, as detailed by the Technical Specification Groups (TSG) within 3GPP. The work completed by 3GPP CT TSG and 3GPP SA TSG, including the release of important documents, is highlighted. Moreover, it outlines the advancements in non-3GPP access network discovery, selection, security association management, and transport procedures. Overall, the update sheds light on the evolving landscape of 5G networks and their integration with diverse access networks.

July 2018 doc.: IEEE 802.11-18/1243r0 Abstract This document provides a brief update of 3GPP, specifically the activity of 3GPP SA TSG and 3GPP CT TSG, related to 3GPP 5G use cases and Non-3GPP Access Networks . Submission Slide 2 Joseph Levy (InterDigital)
July 2018 doc.: IEEE 802.11-18/1243r0 3GPP Activity of Interest (1/2) 3GPP CT TSG has completed and released 3GPP TS 24.502 V15.0.0 (2018-06) 3rd Generation Partnership Project; Technical Specification Group Core Network and Terminals; Access to the 3GPP 5G Core Network (5GCN) via Non-3GPP Access Networks (N3AN); Stage 3 (Release 15) [1] This Technical Specifications: specifies non-3GPP access network discovery and selection procedures, the access authorization procedure used for accessing untrusted non-3GPP access networks. specifies the security association management procedures used for establishing IKEv2 and IPSEC security associations from the UE to the N3IWF and the procedures for transporting messages between the UE N3IWF over the non-3GPP access networks. is applicable to the UE and the network. In this technical specification the network refers to the 3GPP 5GCN and the untrusted non-3GPP access network. This is the Stage 3 document completing the work of 3GPP 23.502 V15.1.0 (2018-03) Stage 2 [2] Submission Slide 3 Joseph Levy (InterDigital)
July 2018 doc.: IEEE 802.11-18/1243r0 3GPP Activity of Interest (2/2) 3GPP SA TSG continues to work 3GPP TS 22.261 V15.5.0 (2018-06) 3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Service requirements for the 5G system; Stage 1 (Release 15) [3] This Technical Specification provides: . describes the service and operational requirements for a 5G system, including a UE, NG-RAN, and 5G Core network. Requirements for a 5G E- UTRA-NR Dual Connectivity in E-UTRAN connected to EPC are found in TS 22.278. [4] Including: High-level requirements , Basic Capabilities , Performance requirements , Security , and Charging aspects Submission Slide 4 Joseph Levy (InterDigital)
July 2018 doc.: IEEE 802.11-18/1243r0 Non-3GPP Access Procedures 3GPP TS 24.502 [1] specifies: Handover of a PDU Session procedure between 3GPP and untrusted non- 3GPP access Procedures for non-3GPP access Registration via Untrusted non-3GPP Access N2 procedures via Untrusted non-3GPP Access UE Requested PDU Session Establishment via Untrusted non-3GPP Access UE or Network Requested PDU Session Modification via Untrusted non-3GPP access UE Requested PDU Session Release via Untrusted non-3GPP access MT SMS over NAS via non-3GPP access Submission Slide 5 Joseph Levy (InterDigital)
July 2018 doc.: IEEE 802.11-18/1243r0 Non-3GPP Access Service and Operational requirements 3GPP TS 22.261 [3] specifies: Multiple access technologies: The 5G system will support 3GPP access technologies, including one or more NR and E-UTRA as well as non-3GPP access technologies. For optimization and resource efficiency, the 5G system will select the most appropriate 3GPP or non-3GPP access technology for a service Connectivity models: The relay UE can access the network using 3GPP or non-3GPP access (e.g., WLAN access, fixed broadband access). Subscription aspects: The direct device connection between the IoT device and the relay UE can be using 3GPP or non-3GPP RAT. Authentication: The 5G system shall be able to support authentication over a non-3GPP access technology using 3GPP credentials. Authorization: Based on operator policy, before establishing a direct device connection using a non-3GPP access technology, IoT devices may use 3GPP credentials to determine if they are authorized to engage in direct device connection.
