A.83 Monitoring of AF traffic influence

28.5523GPP5G performance measurementsManagement and orchestrationRelease 18TS

As described in TS 23.501 [4], an Application Function may send requests to influence SMF routeing decisions for User Plane traffic of PDU Sessions. The AF requests may influence UPF (re)selection and allow routeing of user traffic to a local access (identified by a DNAI) to a Data Network. The AF may request the traffic influence via NEF.

The fulfilment of traffic influence per the request from AF means that the user data traffic is routed according to the requirements from the application, therefore performance measurements are needed to indicate whether the AF traffic influence requests are fulfilled.
