Way forward for addressing the open issues in Way forward for addressing the open issues in SID SID phase phase (1/2) (1/2) Way forward based on email discussion: UP-based join is not supported in Release 17. MB-SMF is assumed to allocate Area session identifier. Determine the details of TMGI and its relationship with SNPN in the normative phase. The interface for PSA receiving MBS data: Support N9 interface only, since N9 could support multicast and unicast. Address the AS-based authorization in the normative phase. Use MBSF+MBTF terminology. ETSUN: no specific issue & unclear requirement. DDoS attack: stage 3 work. Open issues include: Roaming scenario. LBO and HR (see next slides) SMF finding MB-SMF. UDM/NEF/PCF/NRF (see next slides) Seems related to roaming scenario.
Way forward for addressing the open issues in Way forward for addressing the open issues in SID SID phase phase (2/2) (2/2) SMF finding MB-SMF Support of Roaming scenario: HR: Resolvable but Scenario is unclear. LBO: Most parts are the same as non-roaming case, the only issue is, how to let SMF find the MB-SMF See the right figure. May have two UDMs UDR UDM (for MB-SMF) UE UDM (for authorization) Join Currently no similar functionality in NEF SMF NEF (for MB-SMF) UDR How to find MB-SMF? MB-SMF ID is not policy info PCF (for MB-SMF) UDR MB-SMF ID is not a static info NRF (for MB-SMF)
