Based on a successful token validation, the network node may allow UE 102 access to the private network slice identified by the NSI ID, for a secure remote access to the private 5G network of the enterprise. The private network slice may be associated with functions which include at least a UPF, an SMF, and a PCF. Here, the network node may send a message for causing a provisioning of one or more rules in a forwarding entity in the mobile network (step 708 of FIG. 7). The provisioning of the one or more rules in the forwarding entity may be for causing enterprise UP traffic of the UE to be forwarded to an anchor UPF of the private network slice of the enterprise. Using the private network slice, the enterprise UP traffic may be forwarded to the private 5G network of the enterprise. The enterprise UP traffic communication may be used for the remote control and/or monitoring of elements in the private 5G network of the enterprise. The forwarding entity may be or include a router, a gateway, a classifier, a branching point, a Branching Point UPF, or UL-CL, or any combination of the above.
