5G enhanced HetNet gateway

1. A 5G enhanced HetNet Gateway (HNG), comprising:

at least one non-5G virtual network function (VNF) providing 2G, 3G, 4G, or Wi-Fi core network functionality;

a 5G Core (5GC) option selection VNF providing selection of an access network slice and a core network slice;

a 5GC access and mobility management function (AMF) VNF;

a 5G local breakout VNF;

at least one interface for an any G base station; and

at least one interface for a 4G Long Term Evolution core network, which is an Evolved Packet Core (EPC),

wherein core functionality is abstracted for the any G base station and for the 5GC by interworking the 5GC to the any G base station, and wherein signaling traffic from a core is internally processed by the HNG to reduce load on the core.

2. The 5G HNG of claim 1 wherein the non-5G VNF comprises at least one of a 2G core VNF, a 3G core VNF, a 4G core VNF and a Wi-Fi core VNF.

3. The 5G HNG of claim 1 wherein the any G base station comprises at least one of an eNodeB and a gNodeB.

4. The 5G HNG of claim 1 wherein advanced RAN functions are supported for simplifying LTE and NR deployments.

5. The 5G HNG of claim 1 wherein signaling traffic processing for a core results from reduction of signaling traffic for paging and handovers.

6. The 5G HNG of claim 5 wherein signaling traffic reduction for a core allows modification of logical groupings of a number of cells in a Tracking Area (TA).

7. A system comprising:

a 5G Non-Stand-Alone (NSA) base station;

a 5G enhanced HetNet Gateway (HNG) in communication with the NSA base station;

a core network in communication with the 5G enhanced HNG, the core network including at least one of an Evolved Packet Core (EPC) and a 5G Core (5GC); and

wherein the 5G enhanced HNG abstracts core functionality for at least one of the EPC and the 5GC by virtualizing and interworking the at least one of the EPC and the 5GC to the 5G NSA base station, and

wherein signaling traffic from a core is internally processed by the HNG to reduce load on the core.

8. The system of claim 7 wherein the enhanced HNG comprises:

at least one non-5G virtual network function (VNF);

a 5G Core (5GC) option selection VNF;

a 5GC access and mobility management function (AMF) VNF;

a 5G local breakout VNF;

at least one interface for an any G base station; and

at least one interface for any core network.

9. A method of operating A 5G enhanced HetNet Gateway (HNG), comprising:

providing at least one non-5G virtual network function (VNF) for providing 2G, 3G, 4G, or Wi-Fi core network functionality;

providing a 5G Core (5GC) option selection VNF;

providing a 5GC access and mobility management function (AMF) VNF;

a 5G local breakout VNF;

providing at least one interface for an any G base station;

providing at least one interface for a 4G Evolved Packet Core (EPC); and

virtualizing and interworking the EPC to the base station, and

internally processing signaling traffic from a core to reduce load on the core.

10. The method of claim 9 wherein the providing a non-5G VNG comprises providing at least one of a 2G VNF, a 3G VNF, a 4G VNF and a WiFi VNF.

11. The method of claim 9 wherein the providing any G base station comprises providing at least one of an eNodeB and a gNodeB.

12. The method of claim 9 wherein providing advanced RAN functions are supported for simplifying LTE and NR deployments.

13. The method of claim 9 wherein signaling traffic processing for a core results from reduction of signaling traffic for paging and handovers.

14. The method of claim 13 wherein signaling traffic reduction for a core allows modification of logical groupings of a number of cells in a Tracking Area (TA).
