[{"name":"S2-1900037","title":"LS from CT WG4: LS on EPS Interworking Indication with N26 support","source":"CT WG4","contact":"Maurice Pope","contact-id":648,"tdoctype":"LS in","for":"Action","abstract":"CT WG4 has observed a misalignment of Stage 2 requirement with Stage 3 realization for AMF to inform EPS interworking with N26 interface support to SMF. SA WG2 considers AMF to return a negative response to SMF via EBI assignment service operation to implicitly inform SMF that N26 is not supported, as specified in clause 5.17.2.3.1 of TS 23.501: When an AMF in a serving PLMN that does not support 5GS-EPS interworking procedures with N26 interface receives a request to allocate an EBI(s) for a QoS Flow(s) from a PGW-C+SMF, it shall not provide the EBI(s) but reject the EBI allocation request with a specific rejection cause. This is considered an explicit indication by SMF that 5GS-EPS interworking procedures with N26 interface are not supported in the serving PLMN. CT WG4 defines AMF to inform SMF the of N26 interface support for EPS interworking directly during PDU session context setup and update service operation, as in TS 29.502 v15.1.0, the epsInterworkingInd parameter in SmContextCreateData and SmContextUpdateData reads as: When present, this IE shall indicate whether the PDU session may possibly be moved to EPS and whether N26 interface to be used during EPS interworking procedures. The AMF may derive the value of the indication from different sources, like UE radio capabilities (e.g. 'S1 mode supported'), UE subscription data (e.g. 'Core Network Type Restriction to EPC) and configurations. CT WG4 has chosen the above stage 3 solution for the following reasons: 1. It saves network traffic from unnecessary EBI assignment service operation invocations by the SMF to the AMF, when N26 interface is not supported for EPS interworking. 2. The SA WG2 alternative requires the SMF to derive that N26 is not supported from the receipt of a negative response during an EBI assignment procedure. The SMF may not be able then to discover that N26 becomes supported when N26 is enabled in the PLMN, unless the SMF periodically initiates EBI assignment procedures; and 3. As a general protocol design principle, negative responses are intended for abnormal cases. Using negative responses to derive a particular configuration within a PLMN for normal procedures is not preferred in general. Action: CT WG4 kindly asks SA WG2 group to provide feedback if there is any problem with the stage 3 solution specified by CT WG4, and to possibly consider aligning stage 2 if necessary.","secretary_remarks":"Response drafted in S2-1900133.

The AMF includes this EBI and the related ARP in the Create SM Context Request it sends to the SMF to establish the SM Context \/ PDU session. This is done for all types of PDU sessions (HR PDU session, non-roaming and local breakout). For a HR PDU session, the V-SMF forwards this pre-assigned EBI and related ARP to the H-SMF in the Create Request, and the H-SMF returns in the Create Response new information telling the V-SMF whether this EBI has been used as allocated by the AMF, revoked or used with a modified ARP. When the pre-assigned EBI is being revoked or used with a modified ARP, the SMF (or V-SMF for a HR PDU session) invokes the EBI Assignment service to update the AMF with the EBI that is revoked or used with a modified ARP. If the SMF (H-SMF for a HR PDU session) needs to assign more than 1 EBI, the SMF completes first the establishment of the PDU session with one EBI, and then invokes the AMF EBI Assignment service operation (and Nsmf_PDUSession_Update service operation for a HR PDU session) to request the allocation of additional EBIs to the PDU session, using existing procedures.

The AMF includes this EBI and the related ARP in the Create SM Context Request it sends to the SMF to establish the SM Context \/ PDU session. This is done for all types of PDU sessions (HR PDU session, non-roaming and local breakout). For a HR PDU session, the V-SMF forwards this pre-assigned EBI and related ARP to the H-SMF in the Create Request, and the H-SMF returns in the Create Response new information telling the V-SMF whether this EBI has been used as allocated by the AMF, revoked or used with a modified ARP. When the pre-assigned EBI is being revoked or used with a modified ARP, the SMF (or V-SMF for a HR PDU session) invokes the EBI Assignment service to update the AMF with the EBI that is revoked or used with a modified ARP. If the SMF (H-SMF for a HR PDU session) needs to assign more than 1 EBI, the SMF completes first the establishment of the PDU session with one EBI, and then invokes the AMF EBI Assignment service operation (and Nsmf_PDUSession_Update service operation for a HR PDU session) to request the allocation of additional EBIs to the PDU session, using existing procedures.
