[{"name":"S2-2312009","title":"Correction to UPF anchored Mobile Terminated Data Transport in Control Plane CIoT 5GS Optimisation","source":"Intel, [Ericsson]","contact":"Saso Stojanovski","contact-id":24932,"tdoctype":"CR","for":"Approval","abstract":"Summary of change: 1. Clarified that, when UE is not reachable, the following happens: If UE is in MICO mode, the procedure ends in step 2h. If UE is configured for extended idle mode DRX, the AMF takes a note of the SMF s request and proceeds with the rest of the procedure when the UE becomes reachable. Note that a similar clarification was made in SA WG2#157 in the context of the NR_RedCap_Ph2 work item (refer to S2-2307731). In steps 2d\/2h the AMF considers the SMF implicitly subscribed for notification when the UE becomes reachable. 2. Step 8a has been taken out of the Buffering configured in the UPF box and has been replaced with steps 8aa and 8ab: - step 8aa (Namf_MT-EnableUEReachability Response) applies when the AMF has determined in step 2c that the UE was reachable - step 8ab (Namf_EventExposure Notify) applies when in step 2d or 2h the AMF has considered the implicitly subscribed for notification when the UE becomes reachable. 3. Step 8e has been taken out of the Buffering configured in UPF box because it applies to both buffering in UPF and buffering in SMF (in the latter case only if in step 2h the AMF has considered the SMF implicitly subscribed for notification when the UE becomes reachable). 4. Steps 7a, 7b and 7c are enclosed in a Failure cases box. Changes to rev R04: Clause 5.2.2.4.2: Added Reachability Notification URI in the Namf_MT_EnableUEReachability service operation.","secretary_remarks":"Revision of S2-2311793 from S2#159.
