[{"name":"S2-2300055","title":"LS from RAN WG3: Reply LS on long eDRX support for RRC_INACTIVE","source":"RAN WG3","contact":"Philippe Godin","contact-id":68843,"tdoctype":"LS in","for":"Action","abstract":"RAN WG3 thanks SA WG2 for their LS and the accompanying CRs for the support of long eDRX for RRC_INACTIVE state with MT communication handling in CN. RAN WG3 would like to provide the following feedback on SA WG2 s questions and the ENs in S2-2209675: 1. On the triggering criteria for gNB sending a CN based MT communication handling request to CN, it is decided by RAN WG3 to leave it to network implementation. 2. On the NGAP message from NG-RAN node to AMF providing the eDRX information for RRC_INACTIVE and requesting the CN to handle the MT communication (Figure 4.8.1.1a-1 steps 2 and 6), RAN WG3 has made an early agreement to use a class 1 procedure. The details of this class 1 procedure will be discussed by RAN WG3 during the WI phase next year. 3. When the NG-RAN sends an N2 Notification to the AMF indicating the UE is in RRC_CONNECTED (Figure 4.8.2.2-1 step 3b.1), RAN WG3 also discussed the possibility to reuse the NGAP class 2 procedure RRC INACTIVE TRANSITION REPORT message defined in TS 38.413 to indicate AMF that the UE is back to RRC_CONNECTED state, but RAN WG3 has not reached an agreement. RAN WG3 will continue the discussion during the WI phase next year. 4. When the AMF sends an N2 message to NG-RAN node with the request for the UE to be transitioned to RRC_CONNECTED (Figure 4.8.2.2b-1 step 2), RAN WG3 has not yet made a decision whether the existing NGAP CN Paging procedure should be enhanced to support CN Triggered RAN Paging with CN based MT communication handling, or if a new NGAP notification procedure should be defined to trigger RAN paging with CN based MT communication handling. RAN WG3 will continue the discussion during the WI phase next year. In general, RAN WG3 will continue discussing the overall functional impacts of CN based MT communication handling on the RAN WG3 specifications, such as the addition of new IE in the Core Network Assistance Information for RRC INACTIVE IE to indicate CN capability of MT communication handling with long eDRX for RRC_INACTIVE, the XnAP and the F1AP impacts during the NR_redcap_enh WI phase next year (as agreed in RP-222675). Action: RAN WG3 kindly asks SA WG2 to take the above feedback into account.","secretary_remarks":"Response drafted in S2-2300932.
