Function selection based on utilization level in 5G environments
Systems, devices, and techniques described herein are directed to function selection based on utilization level in mobile networks. In particular, the systems, devices, and techniques can be implemented in fifth generation (5G) mobile networks to provide intelligent selection of a user plane function (UPF) based on utilization levels, capability information, and/or locality information. UPFs can provide indications of a utilization level to a network resource function (NRF), which can manage a database of the various utilizations levels of various UPFs. Based on a current, historical, or expected utilization of one or more UPFs, and/or based on the services requested and various locations of the services in a network, the NRF can select and provide, in part, a UPF to the UE, so that the UPF can carry user traffic associated with the UE.
