SMF forwards the PDU Session pair identifier to NG-RAN The two PDU sessions remain paired. This allows the PDU session pair to be handled with two SMFs also more dynamically. Rev2: In last SA WG2#144E meeting, S2-2103047 was technically endorsed with two ENs left to be solved: Editor's Note: It is FFS if and how the URSP rules can be used to configure PDU Session Pair ID. Editor's Note: It is FFS if UE can also provide RSN parameter to the network. This revision proposes solve the two ENs as following: 1, For the first EN, enhance URSP to support PDU Session Pair ID According to the TS 23.501, the duplicated traffic from the application is differentiated by two distinct traffic descriptors with each in a distinct URSP rule. It is easy to configure the RSD corresponding to the two distinct traffic descriptors with same PDU Session Pair ID. 2, For the second EN, there is no need to enhance UE to provide RSN parameter to SMF as it has been approved since R16 that SMF uses S-NSSAI, DNN to determine the RSN value. In addition, this revision proposes the following changes: 3, Describe UE includes PDU Session Pair ID in a separate bullet. 4, Delete PDU Session Pair ID for deciding PDU Session to be handled redundantly. 5, Change 'for more flexible SN and\/or gNB-CU\/DU selection' to 'to support multiple redundant PDU Sessions'. 6, Editorial changes: change 'PDU Session Pair Identifier' to 'PDU Session Pair ID'.","secretary_remarks":"Revision of (Endorsed) S2-2103047. r11 agreed.
