Techniques provided herein extend User Plane mobile core Functions (UPFs) outside the conventional service provider boundary to the enterprise customers’ premises. Between the enterprise-hosted UPF and packet core, secured ES1u/EN3 and ESx/EN4 interfaces and call flows are defined in addition to those in the 3rd Generation Partnership Project (3GPP) standards. These new secured interfaces are further protected by white-list server authorization before secure tunnels are established.
