Monitoring and reporting service performance

Abstract

A user plane function receives from a session management function, a first message requesting at least one quality of service (QoS) report for a data flow of a wireless device. The first message comprising: a first information element indicating a QoS event; and a second information element indicates a latency value for the QoS event. A user plane function sends to the wireless device, monitoring packets for monitoring a packet transmission latency of the data flow. The user plane function determines an occurrence of the QoS event based on the packet transmission latency of the data flow and the latency value. The user plane function sends to the session management function, a second message comprising a third information element indicating the occurrence of the QoS event for the data flow.
