Unique IP address in ad-hoc base station
Systems, methods and computer software are disclosed for providing Internet Protocol (IP) address allocation in a wireless network. In one embodiment, the method includes sending, by a mesh node in the wireless network, an IP request to neighbor nodes; saving, by a gateway node (GW) in the wireless network, the request from the mesh node; proxying, by the GW, the mesh request to a HetNet Gateway (HNG) by providing a transient IP-Sec tunnel; replying, by the HNG, to the GW with a response; forwarding, by the GW, the response to the mesh node, the response including a dummy IP address; and starting, by the mesh node, a Self Optimizing Network (SON) tunnel with the GW using the dummy IP address.
1. A method for providing Internet Protocol (IP) address allocation in a wireless network, comprising:
sending, by a mesh base station in the wireless network, an IP request to neighbor base stations;
saving, by a gateway node (GW) in the wireless network, the request from the mesh base station;
proxying, by the GW, the mesh request to a HetNet Gateway (HNG) by providing a transient IPSec tunnel;
replying, by the HNG, to the GW with a response;
forwarding, by the GW, the response to the mesh base station, the response including a dummy IP address; and
starting, by the mesh base station, a Self Optimizing Network (SON) tunnel with the GW using the dummy IP address.
2. The method of claim 1 wherein the mesh base station has two GW neighbors further comprising:
requesting the IP address for both GW neighbors; and
using the IP address received first; and
ignoring any other responses.
3. The method of claim 1 further comprising, after the sending the IP request to neighbor base stations, forwarding by mesh neighbor base stations having a dummy IP address, the request to other neighbor base stations.
4. The method of claim 1 wherein sending the IP request to neighbor base stations comprises sending a broadcast message on all interfaces of the mesh base station.
5. The method of claim 4 wherein sending a broadcast message on all interfaces of the mesh base station comprises sending a broadcast message including a Radio Access Network Identifier (RAN ID) and a Fully Qualified Domain Name (FQDN) of the HNG.
6. The method of claim 5 further comprising performing, by the GW, Domain Name System (DNS) resolution on the FQDN.
7. The method of claim 6 further comprising starting, by the GW, an IP-Sec tunnel with the HNG based on an address acquired by the Domain Name system (DNS) resolution on the FQDN.
8. The method of claim 7 further comprising tearing down, by the GW, the IPSec tunnel after receiving a response from the mesh node.
9. A system for providing Internet Protocol (IP) address allocation in a wireless network, comprising:
a gateway (GW) node;
a mesh base station in communication with the GW;
a HetNet Gateway (HNG) in communication with the GW;
wherein the mesh base station sends an IP request to neighbor base stations;
the GW node saves the request from the mesh base station;
the GW proxies the mesh request to the HNG by providing a transient IPSec tunnel;
the HNG replies to the GW with a response;
the GW forwards the response to the mesh base station, the response including a dummy IP address; and
the mesh base station starts a Self Optimizing Network (SON) tunnel with the GW using the dummy IP address.
10. The system of claim 9 wherein, after the IP request is sent to neighbor base stations, mesh neighbor base stations having a dummy IP address forward the request to other neighbor base stations.
11. The system of claim 9 wherein the IP request sent to neighbor base stations is sent on all interfaces of the mesh base station.
12. The system of claim 11 wherein the broadcast message sent on all interfaces of the mesh base station comprises a broadcast message including a Radio Access Network Identifier (RAN ID) and a Fully Qualified Domain Name (FQDN) of the HNG.
13. The system of claim 12 wherein the GW performs Domain Name System (DNS) resolution on the FQDN.
14. The system of claim 13 wherein the GW starts an IPSec tunnel with the HNG based on an address acquired by the DNS resolution on the FQDN.
15. A non-transitory computer-readable medium containing instructions for providing Internet Protocol (IP) address allocation in a wireless network, comprising:
sending, by a mesh base station in the wireless network, an IP request to neighbor base stations;
saving, by a gateway node (GW) in the wireless network, the request from the mesh base station;
proxying, by the GW, the mesh request to a HetNet Gateway (HNG) by providing a transient IPSec tunnel;
replying, by the HNG, to the GW with a response;
forwarding, by the GW, the response to the mesh base station, the response including a dummy IP address; and
starting, by the mesh base station, a Self Optimizing Network (SON) tunnel with the GW using the dummy IP address.
16. The non-transitory computer-readable medium of claim 15 further including instructions for, after the sending the IP request to neighbor base stations, forwarding by mesh neighbor nodes having a dummy IP address, the request to other neighbor base stations.
17. The non-transitory computer-readable medium of claim 15 further including instructions wherein sending the IP request to neighbor base stations comprises sending a broadcast message on all interfaces of the mesh base station.
18. The non-transitory computer-readable medium of claim 17 further including instructions wherein sending a broadcast message on all interfaces of the mesh base station comprises sending a broadcast message including a Radio Access Network Identifier (RAN ID) and a Fully Qualified Domain Name (FQDN) of the HNG.
19. The non-transitory computer-readable medium claim 15 further including instructions for performing, by the GW, Domain Name System (DNS) resolution on the FQDN.
20. The non-transitory computer-readable medium of claim 19 further comprising instructions for starting, by the GW, an IPSec tunnel with the HNG based on an address acquired by the DNS resolution on the FQDN.
