Abstract
This invention is a system and method for implementing Network Function (NF) Proxy in an IPX network for 5G core roaming. NF Discover queries from Visited Public Land Mobile Network (VPLMN) are manipulated such that the IPX NF Proxy's fully qualified domain name (FQDN) is returned as the FQDN of the Home Public Land Mobile Network (HPLMN) NF. NF Proxy queries the FQDN of a true HPLMN NF through a HPLMN Network Repository Function (NRF) Proxy. Application messages are routed to NF Proxy hosted in the IPX network. NF Proxy performs its proxy function and routes egress messages to the target NF in HPLMN or another location.
