[{"name":"S2-2303941","title":"LS from CT WG4: LS on Network Triggered Service Request for a UE in Suspend State","source":"CT WG4","contact":"Yong Yang","contact-id":42295,"tdoctype":"LS in","for":"Action","abstract":"CT WG4 discussed how Network Triggered Service Request for a UE in Suspend State should work. As noted in clause 4.2.3.3 of 3GPP TS 23.502, upon receiving subsequent DL Data report from the UPF for a PDU session of which user plane connection is suspended, the SMF shall trigger a Network Triggered Service Request as the UE is considered as CM Idle: NOTE 3: This step is performed also when the UE and the network support User Plane CIoT 5GS Optimisation and the previous RRC connection has been suspended. In this procedure, the SMF needs include a N2 Information in N1N2MessageTransfer request (for network triggered service request). CT WG4 would like to ask SA WG2: Question1: What information should the SMF include in the N2 Information for the N1N2MessageTransfer Request message? Question2: Upon subsequent Connection Resume in CM-IDLE with Suspend procedure as response to the paging, how should the AMF deal with the N2 Information received in the N1N2MessageTransfer Request triggering the paging (the AMF is expected to send an N2 Connection Resume Response or N2 Path Switch Ask to NG-RAN, see clause 4.8.2.3 of 23.502)?. Action: CT WG4 kindly requests SA WG2 to answer CT WG4's questions, and to consider updating their specifications if necessary.","secretary_remarks":"Response drafted in S2-2304193.
