With reference back to FIG. 5, again, the enterprise UP traffic of UE 102 may be forwarded and routed toward and to anchor UPF 540 in “Slice 1” along the path 530 to the private 5G network 522 of the factory, whereas the subscriber UP traffic of UE 102 may be forwarded and routed in “Slice 2” along the path 532 to the Internet 520 or other network. The enterprise UP traffic communication may be used for remote control and/or monitoring of elements in the private 5G network 522 of the factory.

FIG. 7 is a flowchart 700 for describing a method for secure access to a private network slice of a mobile network (e.g. 5G network) of an MVNO for communications, suitable for a secure remote access to a private network (e.g. a private 5G network) of an enterprise. The method may be performed by one or more network nodes of the mobile network (e.g. 5G network), where a network node may include a function such as an NF or AF which performs the method. A network node may include one or more processors and one or more network interfaces, where the one or more processors are configured to perform the steps of the method. The method may be embodied as a computer program product which includes a non-transitory computer readable medium and computer instructions stored in the non-transitory computer readable medium, where the computer instructions are executed by one or more processors of the network node of the mobile network.
