1. A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a processor of a management function in a wireless network, cause the processor to:
establish a user plane connection with one or more user equipment (UE) in the wireless network;
decode uplink (UL) end-to-end (e2e) latency measurement packets from the one or more UE, the UL e2e latency measurement packets comprising data to indicate respective first time stamps when the one or more UE transmitted the UL e2e latency measurement packets;
record respective second time stamps corresponding to reception of the UL e2e latency measurement packets from the one or more UE;
calculate, at the management function, based on the first time stamps and the second time stamps, a UL e2e latency for the UL e2e latency measurement packets from the one or more UE; and
generate a report message to indicate the UL e2e latency for transmission, from the management function to a service consumer application, wherein the management function and the service consumer application reside in a same data center.
