Abstract
Various embodiments comprise a Fifth Generation (5G) visited wireless communication network to interwork with a Long Term Evolution (LTE) home network. In some examples, the 5G visited wireless communication network comprises an Access and Mobility Management Function (AMF) and an Interworking Function (IWF). The AMF receives a service request from a 5G capable visiting user device. The AMF generates Fifth Generation Core (5GC) authentication signaling to authenticate the visiting user device. Prior to delivering the 5GC authentication signaling to the home network, the IWF translates the 5GC authentication signaling into Evolved Packet Core (EPC) authentication signaling and transfers the EPC authentication signaling to the home network. The IWF receives an EPC authentication response from the home network and translates the EPC authentication response into a 5GC authentication response. The AMF authenticates the visiting user device for service on the 5G visited wireless communication network based on the 5GC authentication response.
