Study on access traffic steering, switch and splitting support in the 5G System (5GS) architecture; Phase 2
This Technical Report investigates following aspects for UEs that can establish a MA PDU Session to 5GC over both 3GPP and non-3GPP accesses:
- Whether and how to support additional steering mode(s), with potential PMF extensions if needed.
- Whether and how to support additional steering functionality(ies). Proposed solutions shall be based on IETF protocols or extension of such protocols (i.e. QUIC/MP-QUIC).
- Whether and how to support multi-access PDU session with one 3GPP access leg over EPC and the other access leg over non-3GPP access 5GS.
