[{"name":"S2-2407393","title":"LS from CT WG4: LS on MPS PDU Session Handling for Non-MPS Subscriber","source":"CT WG4","contact":"Maurice Pope","contact-id":648,"tdoctype":"LS in","for":"Action","abstract":"In 5G Core Networks, the SBI messages between network functions are handled with different message priorities over HTTP layer, e.g. the messages serving Multimedia Priority Service (MPS) subscribers will be handled with higher priority than non-MPS subscribers. For a MPS subscriber, the serving AMF and SMF(s) will prioritize the messages over N11 based on the subscription information received from UDM. For a service session involving both MPS subscribers and non-MPS subscriber (e.g. the MPS subscriber makes a voice call to a non-MPS subscriber), the PDU session of the non-MPS subscribers shall also be handled in high priority for end-to-end service assurance. In such a scenario, the SM Policy PCF for the non-MPS subscriber can get MPS priority indication from IMS system and inform the SMF to apply MPS priority for the IMS PDU session temporarily. The SMF then set high priority for SBI service requests towards the AMF. However, if the AMF is not aware about the MPS priority of the PDU session and it does apply normal priority for SBI service request towards the SMF, N11 signalling initiated by the AMF may be discarded by the SMF when overloaded or congested, and the service flow will fail. CT WG4 kindly asks SA WG2 whether there is existing stage 2 procedure to allow the AMF serving non-MPS subscriber also be informed to temporarily apply high priority for the PDU session in above scenario. If not CT WG4 would like to ask SA WG2 to define the corresponding stage 2 procedure if possible. Action: CT WG4 kindly asks SA WG2 to evaluate the above scenario and indicate the corresponding stage 2 procedure if exists. Or otherwise define the corresponding stage 2 procedure if possible.","secretary_remarks":"Revision of postponed S2-2405867 from S2#163. Response drafted in S2-2407975.
