[{"name":"S2-2000022","title":"LS from CT WG1: LS on Dual-registration requirements for EHPLMNs","source":"CT WG1","contact":"Robert Zaus","contact-id":10799,"tdoctype":"LS in","for":"Action","abstract":"CT WG1 is currently discussing the requirements for Dual-Registration mode and specifically for the scope of the indication of support of interworking without N26. In this regard, at CT WG1#120, CT WG1 agreed a Release-16 CR (C1-196447). 1) According to stage 2, TS 23.501, subclause 5.17.2.3.1, 'The indication that interworking without N26 is supported [is valid] for the entire Registered PLMN and for PLMNs equivalent to the Registered PLMN that are available in the Registration Area. The same indication is provided to all UEs served by the same PLMN. UEs that operate in interworking without N26 may use this indication to decide whether to register early in the target system. If the Registered PLMN is a VPLMN, i.e. a PLMN different from the HPLMN and different from any Equivalent HPLMN (EHPLMN), then the term 'PLMNs equivalent to the Registered PLMN' can only be referring to the list of 'equivalent PLMNs'. Generally, the list of equivalent PLMNs and the list of EHPLMNs can include different PLMNs, but an operator may decide to signal some or all PLMNs from the EHPLMN list also as equivalent PLMNs. If the UE is currently registered on an EHPLMN, the wording 'PLMNs equivalent to the Registered PLMN' in the above sentence in TS 23.501 could be interpreted as referring to: i) the list of equivalent PLMNs; ii) the list of EHPLMNs; or iii) the combination of lists i) and ii). Question 1: Which of these interpretations should be used by CT WG1 for Rel-16? Note that for Rel-15, CT WG1 has chosen interpretation i), i.e. according to TS 24.501 the UE needs to choose the PLMN for the second registration from the list of equivalent PLMNs. Action: CT WG1 asks SA WG2 1) to answer question 1) and to clarify stage 2 requirements for the support indication of interworking without N26 in TS 23.501.","secretary_remarks":"Postponed S2-1911954 from SA2#136.

The AMF first marks EBI values in range 1-4 'not to be transferred' which means the QoS Flows associated with those EBIs are not to be transferred to EPS. If there are still more than 8 EBI values, the AMF then determines EBI value(s) not to be transferred based on S-NSSAI, and ARP PL and PVI value(s). #3 If the AMF determines that a PDU Session is not to be transferred to EPS, then AMF does not retrieve UE's EPS PDN connection. If the AMF determines that a PDU Session has some QoS Flows to be transferred, then the AMF attempts to retrieve the UE EPS PDN Connection, including the EBI list indicating the corresponding EPS bearers are not to be transferred. Case-1 (V-)SMF returns the UE EPS Connection if the EBI associated with the default QoS Flow is not included in the 'EBI list not to be transferred'; Case-2 if EBI associated with the default QoS Flow is included in the 'EBI list not to be transferred' (which is not expected to happen if ARP PVI is set appropriately, but just in case), the (V-)SMF does not return UE EPS PDN Connection, i.e. SM Context retrieval failed. #4 The AMF initiates PDU Session release PDU Sessions that are not transferred to the MME, including PDU Session(s) without SM context retrieval, or PDU Session(s) with failed SM Context retrieval. #5 For PDU Session transferred to the EPS, if there are EPS bearers mapped from QoS Flows that are not included in Modify Bearer Request, the PGW-C+SMF release those QoS Flows.","secretary_remarks":"Revised in parallel session, merging S2-2000535, to S2-2001085.","agenda_item_sort_order":21,"ainumber":"6.9","ainame":"Interworking and Migration","tdoc_agenda_sort_order":12960,"status":"revised","reservation_date":"2020-01-03 22:06:55","uploaded":"2020-01-07 04:54:42","revisionof":"","revisedto":"S2-2001085","release":"Rel-16","crspec":"23.502","crspecversion":"16.3.0","workitem":[{"winame":"5GS_Ph1"},{"winame":"TEI16"}],"crnumber":1980.0,"crrevision":"","crcategory":"F","tsg_crp":"","lsreplyto":"","lsto":"","Cc":"","lsoriginalls":"","lsreply":"","link":"http:\/\/www.3gpp.org\/ftp\/tsg_sa\/WG2_Arch\/TSGS2_136AH_Incheon\/Docs\/S2-2000286.zip","group":"S2","meeting":"S2-ah-35699","year":2020,"uicc_affected":null,"me_affected":null,"ran_affected":null,"cn_affected":null,"clauses_affected":null,"crsinpack":null,"crsinpacknumber":0},

{"name":"S2-2001680","title":"Not supporting 15 EPS bearers at 5GS to EPS mobility","source":"Ericsson","contact":"Shabnam Sultana","contact-id":21207,"tdoctype":"CR","for":"Approval","abstract":"Summary of change: #1 At 5GS to EPS mobility, the AMF knows the target MME does not support 15 EPS bearers through local configuration; #2 If AMF has already allocated more than 8 EBI values, the AMF marks the EBI values as follows to ensure that not more than 8 EPS bearers will be transferred to the MME. The AMF first determines EBI values in range 1-4 as not to be transferred, which means the QoS Flows associated with those EBIs are not to be transferred to EPS. If there are still more than 8 EBI values, the AMF then determines EBI value(s) not to be transferred based on S-NSSAI, and ARP PL and PVI value(s). #3 If the AMF determines that a PDU Session is not to be transferred to EPS, then AMF does not retrieve UE's EPS PDN connection. If the AMF determines that a PDU Session has some QoS Flows to be transferred, then the AMF attempts to retrieve the UE EPS PDN Connection, including the EBI list. Case-1 (V-)SMF returns the UE EPS Connection if the EBI associated with the default QoS Flowcan be transferred; Case-2 if EBI associated with the default QoS Flow can not be transferred (which is not expected to happen if ARP PVI is set appropriately, but just in case), the (V-)SMF does not return UE EPS PDN Connection, i.e. SM Context retrieval failed. #4 The AMF initiates PDU Session release PDU Sessions that are not transferred to the MME, including PDU Session(s) without SM context retrieval, or PDU Session(s) with failed SM Context retrieval. #5 For PDU Session transferred to the EPS, if there are EPS bearers mapped from QoS Flows that are not included in Modify Bearer Request, the PGW-C+SMF release those QoS Flows.","secretary_remarks":"e-ail revision 5 of S2-2001132.
