[{"name":"S2-2103717","title":"LS from CT WG1: LS on interworking to 5GS with N26 due to UE\u2019s N1 mode capability disabling\/enabling","source":"CT WG1","contact":"Lin Shu","contact-id":43310,"tdoctype":"LS in","for":"Action","abstract":"CT WG1 has defined disabling and re-enabling of UE's N1 mode capability for 3GPP access (see TS 24.501 subclause 4.9.2). After the UE has disabled its N1 mode capability for 3GPP access, the UE will move to 4G and indicate EPC that N1 mode not supported (i.e. the UE does not support 5GC NAS). With above, CT WG1 has discussed following sceanrio: (1) The UE operating in single-registration mode has disabled its N1 mode capability when registered in 5G and then moves to 4G of the current PLMN with N26 interface supported. (2) The UE initiates an EPS attach or TAU procedure in 4G during which the UE will indicate N1 mode is not supported. (3) Hereafter, the UE requests to establish a new PDN connection in 4G during which the UE will not generate the PDU session ID included in the (e)PCO IE to the network and the network will not include the mapped PDU session parameters (e.g. QoS flow descriptions, Session-AMBR, QoS rules) included in the (e)PCO IE to the UE. (4) The UE re-enables its N1 mode capability in 4G and then moves back to 5G. As in step (3), there is no mapped PDU session parameters included in the PDN connection, this PDN connection cannot be transferred to 5G in step (4). Session continuity for 5GS interworking was broken. CT WG1 would like to ask SA WG2: (1) If in above step (3), a combo PGW-C+SMF was selected for the PDN connection, whether and how to maintain the session continuity for this PDN connection when moving back to 5G? (2) If in above step (3), a standalone PGW was selected for the PDN connection, whether and how to maintain the session continuity for this PDN connection when moving back to 5G?. Action: CT WG1 kindly asks SA WG2 to answer above questions.","secretary_remarks":"Revision of Postponed S2-2102085 from S2#144E. Response drafted in S2-2103992.

(the UE has released it per item 1 above) The MME tries to transfer to 5GS a PDN connection that was established over EPC on a SMF+ PGW-c. what happens next is discussed below. At EPS to 5GS HO, the initial AMF invokes (step 4 of figure 4.11.1.2.2.2-1) the Nsmf_PDUSession_CreateSMContext service operation (UE EPS PDN Connection, initial AMF ID, data Forwarding information, Target ID) on the SMF identified by the SMF+PGW-C address and indicates HO Preparation Indication (to avoid switching the UP path). \u2026.

In summary, the R17 behavior is the same than in R16 except that R17 specifications supports the UE option where the UE sends a PDU Session ID to the network when establishing a PDN connection while N1 mode is Disabled R17 specificiation supports MME initiating PDN disconnection with reactivation required when N1 mode is (re-)enabled if MME has selected standalone PGW.","secretary_remarks":"Revision of (Endorsed) S2-2103059.
