[{"name":"S2-2105258","title":"LS from CT WG4: Reply LS on Group Subscriptions","source":"CT WG4","contact":"Bruno Landais","contact-id":68755,"tdoctype":"LS in","for":"Action","abstract":"CT WG4 thanks SA WG2 for their Reply LS on Group Subscriptions (S2-2103229). Regarding the following answer: Q4: During an inter-AMF mobility of a group member of a group subscription in S-AMF, does the group subscription that T-AMF creates, when there was no corresponding group subscription in T-AMF, only apply to the group member just moving from S-AMF, and not to other group members registered in T-AMF? SA WG2 answer: The group subscription needs to be established and if the UE is the first group member in the T-AMF, then the T-AMF shall generate new subscription correlation ID and inform the Notification Target Address (NEF) of it. TS 23.502 clause 4.15.4.2 was recently updated (in S2-2101579) to specify that the UE specific parameter state is transferred between the AMFs, i.e. the actual remaining quota (including no quota remaining, if the monitoring has not been cancelled yet at the time of context transfer) for each UE is transferred from the S-AMF to the T-AMF. The initial values of Maximum number of reports and Maximum duration of reporting of the group monitoring event are also transferred from the S-AMF to the T-AMF to enable the T-AMF to create the group event configuration when needed (i.e. when the first UE of the group moves into a T-AMF that does not have the group event configuration). If there is at least one other group member already registered in the T-AMF during group event subscription, the group event subscription already exists in T-AMF. CT WG4 kindly ask SA WG2 to note that per existing stage 3 specifications, the T-AMF notifies the UDM about the new subscription creation at the T-AMF, not the NEF, for AMF event subscriptions created by UDM on behalf of the NEF (see Table 6.2.6.2.4-1 of 3GPP TS 29.518). For such subscriptions, the NEF needs not be aware of the AMFs that hold the group subscriptions, since it modifies or cancels these subscriptions via the UDM. CT WG4 assumes that SA WG2 does not intend to change the existing behaviour. Action: CT WG4 kindly ask SA WG2 to take note of the above information and to respond to CT WG4 if CT WG4 assumption is not correct.","secretary_remarks":"Response drafted in S2-2106038.
