Locally-generated TEIDs for core high availability

1. A method for providing core High Availability (HA) for a wireless network, comprising:

providing a first node, a second node and a third node;

allocating, by the first node, a set of locally generated Tunnel Endpoint Identifiers (TEIDs) for UEs anchored on the second node, assigning the TEIDs to tunnels, storing a mapping for each TED to the second node;

detecting, by a first node, a second node having a connectivity issue; and

migrating a User Equipment (UE) connected to the second node to a third node which is accessible; using the set of locally generated TEIDs which identify a core and are used to identify the UE migration to provide undisrupted connectivity.

2. The method of claim 1 wherein the first node comprises a HetNet Gateway (HNG), the second node comprises a first SGW, and the third node comprises a second S-GW.

3. The method of claim 1 wherein the first node comprises a HetNet Gateway (HNG), the second node comprises a first MME, and the third node comprises a second MME.

4. The method of claim 1 wherein the first node comprises a controller, the second node comprises a first SGW, and the third node comprises a second S-GW.

5. The method of claim 1 wherein the first node comprises a controller or ePDG/TWANGW HetNet Gateway (HNG), the second node comprises a second PGW, and the third node comprises a third PGW.

6. The method of claim 1 wherein the first node comprises a controller or ePDG/TWANGW HetNet Gateway (HNG), the second node comprises a first AAA, and the third node comprises a second AAA.

7. The method of claim 1 wherein the wireless network is a Mobile Operator Core Network (MOCN) or a Gateway Core Network (GWCN) and using at least a portion of Si Application Protocol (S1AP) Identifiers (IDs) to identify all UEs belonging to individual operators and to identify operators belonging to all UEs.

8. A system for providing core High Availability (HA) for a wireless network, comprising:

a first node;

a second node in communication with the first node;

a third node in communication with the first node and the second node;

wherein a set of locally generated Tunnel Endpoint Identifiers (TEIDs) are identified for UEs anchored on the second, wherein the TEIDs are assigned to tunnels, and wherein a mapping is stored for each TEID to the second node;

wherein the first node detects the second node having a connectivity issue; and

wherein a User Equipment (UE) connected to the second node is migrated to the third node using the set of locally generated TEIDs which identify a core and are used to identify the UE migration to provide undisrupted connectivity.

9. The system of claim 8 wherein the first node comprises a HetNet Gateway (HNG), the second node comprises a first SGW, and the third node comprises a second S-GW.

10. The system of claim 8 wherein the first node comprises a HetNet Gateway (HNG), the second node comprises a first MME, and the third node comprises a second MME.

11. The system of claim 8 wherein the first node comprises a controller, the second node comprises a first SGW, and the third node comprises a second S-GW.

12. The system of claim 8 wherein the first node comprises a controller or ePDG/TWANGW HetNet Gateway (HNG), the second node comprises a second PGW, and the third node comprises a third PGW.

13. The system of claim 8 wherein the first node comprises a controller or ePDG/TWANGW HetNet Gateway (HNG), the second node comprises a first AAA, and the third node comprises a second AAA.

14. The system of claim 8 wherein the wireless network is a Mobile Operator Core Network (MOCN) or a Gateway Core Network (GWCN) and using at least a portion of Si Application Protocol (S1AP) Identifiers (IDs) to identify all UEs belonging to individual operators and to identify operators belonging to all UEs.

15. A non-transitory computer-readable medium containing instructions for core High Availability (HA) for a wireless network which, when executed, cause a first node to perform steps comprising:

detecting, by a first node, a second node having a connectivity issue; and

migrating a User Equipment (UE) connected to the second node to a third node which is accessible; using the set of locally generated TEIDs for UEs anchored on the second node and which identify a core and are used to identify the UE migration to provide undisrupted connectivity, wherein the TEIDs are assigned to tunnels and wherein a mapping for each TED to the second node is stored.

16. The non-transitory computer-readable medium of claim 15 further comprising instructions wherein the first node comprises a HetNet Gateway (HNG), the second node comprises a first SGW, and the third node comprises a second S-GW.

17. The non-transitory computer-readable medium of claim 15 further comprising instructions wherein the first node comprises a HetNet Gateway (HNG), the second node comprises a first MME, and the third node comprises a second MME.

18. The non-transitory computer-readable medium of claim 15 further comprising instructions wherein the first node comprises a controller, the second node comprises a first SGW, and the third node comprises a second S-GW.

19. The non-transitory computer-readable medium of claim 15 further comprising instructions wherein the first node comprises a controller or ePDG/TWANGW HetNet Gateway (HNG), the second node comprises a second PGW, and the third node comprises a third PGW.

20. The non-transitory computer-readable medium of claim 15 further comprising instructions wherein the first node comprises a controller or ePDG/TWANGW HetNet Gateway (HNG), the second node comprises a first AAA, and the third node comprises a second AAA; or wherein the wireless network is a Mobile Operator Core Network (MOCN) or a Gateway Core Network (GWCN) and using at least a portion of Si Application Protocol (S1AP) Identifiers (IDs) to identify all UEs belonging to individual operators and to identify operators belonging to all UEs.
