Abstract

Systems, methods and computer software are disclosed for providing a bubble network are described. In one embodiment, a method is disclosed including providing an isolated base station having a coverage area, providing a local HetNet Gateway (HNG) disposed within the coverage area and in communication with the isolated base station, providing a local Evolved Packet Core (EPC) in communication with the local HNG and disposed within the coverage area, and wherein the bubble network is disconnected from a mobile operator core network.

First claim

The invention claimed is:

1. A system for providing a mobile base station bubble network, comprising:
an isolated base station wherein backhaul is not available, the isolated base station having a coverage area and providing services to a group of localized users;
a local HetNet Gateway (HNG) disposed within the coverage area and in communication with the isolated base station;
a local Evolved Packet Core (EPC) in communication with the local HNG and disposed within the coverage area;
wherein the bubble network is disconnected from a mobile operator core network; and
wherein the local HNG synchronizes with a remote HNG when a connection between the local HNG and remote HNG is available; and
a loopback from the local EPC to the local HNG.

2. The system of claim 1 wherein the local EPC synchronizes with a remote EPC when the connection between the local HNG and remote HNG is available.

3. The system of claim 2 wherein the connection is an Internet Protocol Security (IPsec) connection.

4. The system of claim 1 wherein the network is at least one of 2G, 3G, 4G/LTE, 5G standalone/nonstandalone network.

5. A method providing a mobile base station bubble network, comprising:
providing an isolated base station wherein backhaul is not available, the isolated base station having a coverage area and providing services to a group of localized users;
providing a local HetNet Gateway (HNG) disposed within the coverage area and in communication with the isolated base station;
providing a local Evolved Packet Core (EPC) in communication with the local HNG and disposed within the coverage area;
wherein the bubble network is disconnected from a mobile operator core network;
synchronizing the local HNG with a remote HNG when a connection between the local HNG and remote HNG is available;
providing a loopback from the local EPC to the local HNG.

6. The method of claim 5 further comprising synchronizing the local EPC with a remote EPC when the connection between the local HNG and remote HNG is available.

7. The method of claim 6 wherein the connection is an Internet Protocol Security (IPsec) connection.

8. The method of claim 5 wherein the network is at least one of 2G, 3G, 4G/LTE, 5G standalone/nonstandalone network.

9. A non-transitory computer-readable medium containing instructions for a mobile base station bubble network which, when executed, cause a system to perform steps comprising:
operating an isolated base station wherein backhaul is not available, the isolated base station having a coverage area and providing services to a group of localized users;
operating a local HetNet Gateway (HNG) disposed within the coverage area and in communication with the isolated base station;
operating a local Evolved Packet Core (EPC) in communication with the local HNG and disposed within the coverage area;
wherein the bubble network is disconnected from a mobile operator core network; synchronizing the local HNG with a remote HNG when a connection between the local HNG and remote HNG is available; and
operating a loopback from the local EPC to the local HNG.

10. The computer-readable medium of claim 9 further comprising instructions for synchronizing the local EPC with a remote EPC when a connection between the local HNG and remote HNG is available.

11. The computer-readable medium of claim 10 further comprising instructions wherein the connection is an Internet Protocol Security (IPsec) connection.

12. The computer-readable medium of claim 9 further comprising instructions wherein the network is at least one of 2G, 3G, 4G/LTE, 5G standalone/nonstandalone network.
