The handover could occur from a source NG-RAN to the target NG-RAN that are served by different AMFs. During the handover, the PDU sessions and QoS flows need to be setup in the target side. The failure of the PDU session setup or QoS flow setup during the inter-AMF handover has direct impact to the user’s experience. Therefore, it is necessary to monitor the performance related to PDU session setup or QoS flow setup for the Inter-AMF handover.
