Abstract: In some implementations, a session management function (SMF) may transmit, to a network data analytics function (NWDAF), an analytics message that requests or subscribes to analytics for user equipment (UE) to user plane function (UPF) (UE-to-UPF) latency. The SMF may receive, from the NWDAF, analytics information in response to the analytics message, wherein the analytics information indicates present or future predicted UE-to-UPF latency information for one or more of a downlink direction or an uplink direction. The SMF may transmit a session modify message to modify a protocol data unit (PDU) session, wherein the PDU session is to be modified based on a UPF selection, and the UPF selection is based on the analytics information.

Abstract: A device may receive network data identifying uplink/downlink packet loss percentage, uplink/downlink jitter, uplink/downlink latency, and uplink/downlink packet throughput associated with a slice of a network, and may set an uplink value for each of the uplink packet loss percentage, the uplink jitter, the uplink latency, and the uplink packet throughput. The device may multiply the uplink values by corresponding uplink weights to calculate an uplink cost, and may set a downlink value for each of the downlink packet loss percentage, the downlink jitter, the downlink latency, and the downlink packet throughput. The device may multiply the downlink values by corresponding downlink weights to calculate a downlink cost, and may calculate a total cost based on the uplink cost and the downlink cost. The device may cause another slice, with the same attributes as the slice, to be instantiated when the total cost satisfies a threshold for a time period.
