Mobile network architectures, such as Fifth Generation Core (5GC) architectures are designed to serve a variety of use cases in which each of the use cases can demand very different network resource allocation and traffic treatment. The introduction of the Control and User Plane separation (CUPS) architecture in the Evolved Packet Core (EPC) mobile network architecture, requires the control plane (CP) to select an appropriate User Plane Function (UPF) to serve a service request from a user equipment (UE) with a desired Quality of Service (QoS). This proposal provides techniques through which optimum UPF usage can be determined by considering multiple load factors, which can aid in performing UPF selection for 5GC and CUPS/EPC mobile network architectures.
