5G Mobile Network With Intelligent 5G Non-Standalone (NSA) Radio Access Network (RAN)

A system for providing a 5G mobile network, comprising:

• a first base station having a first coverage area for a first Radio Access Network (RAN);
• a second base station having a second coverage area, the second coverage area within the first coverage area of the first base station for an overlay RAN;
• a 5G base station having a third coverage area, the third coverage area within the first coverage area and within the second coverage area and part of the overlay RAN;
• and
• a 5G Interworking Function (IWF) device;
• wherein the IWF determines which subscribers are to be serviced by the overlay RAN and which subscribers are to be serviced by the first RAN.

A non-transitory computer-readable medium containing instructions for providing a 5G mobile network which, when executed, cause a system to perform steps comprising:

• providing a first base station having a first coverage area for a first Radio Access Network (RAN);
• providing a second base station having a second coverage area, the second coverage area within the first coverage area of the first base station for an overlay RAN;
• providing a 5G base station having a third coverage area, the third coverage area within the first coverage area and within the second coverage area and part of the overlay RAN;
• and
• determining, by a 5G Interworking Function (IWF) device, which subscribers are to be serviced by the overlay RAN and which subscribers are to be serviced by the first RAN.
