Abstract

A method, computer readable media and system for providing X2 Gateway (GW) multi-cell support, comprising: are presented. In one embodiment a method includes providing a system having a Virtual Radio Unit (VRU) in communication with a Het Net Gateway (coordinating server); exchanging non-content X2 request messages between the VRU and the coordinating server; exchanging non-content X2 response messages between the VRU and the coordinating server; and wherein the non-content X2 request messages and the X2 response messages are used to communicate multiple cells served by the VRU to the coordinating server.

Claims (32)

1 . A method for providing X2 Gateway (GW) multi-cell support, comprising:

providing a system having a Virtual Radio Unit (VRU) in communication with a coordinating server);

exchanging non-content X2 request messages between the VRU and the coordinating server; exchanging non-content X2 response messages between the VRU and the coordinating server; and

wherein the non-content X2 request messages and the X2 response messages are used to communicate multiple cells served by the VRU to the coordinating server.

2 . The method of claim 1 further comprising wherein the messages are used to provide X2 setup by the VRU.

3 . The method of claim 1 further comprising wherein the messages are used to add a new call.

4 . The method of claim 1 further comprising wherein the messages are used to delete an existing call.

5 . The method of claim 1 wherein exchanging non-content X2 request messages between the VRU and the coordinating server further comprises storing a serving cell for the VRU at a Virtual eNodeB data base (VeNBDB).

6 . The method of claim 5 further comprising updating served cell information for the VRU at a Virtual eNodeB (VeNB).

7 . The method of claim 1 wherein the VRU comprises a Centralized Unit (CU) and a Distributed Unit (DU), or a Remote Radio Head (RRH).

8 . A non-transitory computer-readable medium containing instructions for providing X2 Gateway (GW) multi-cell support, when executed, cause the system to perform steps comprising:

providing a system having a Virtual Radio Unit (VRU) in communication with a coordinating server;

exchanging non-content X2 request messages between the VRU and the coordinating server; exchanging non-content X2 response messages between the VRU and the coordinating server; and

wherein the non-content X2 request messages and the X2 response messages are used to communicate multiple cells served by the VRU to the coordinating server.

9 . The non-transitory computer-readable medium of claim 8 further comprising instructions wherein the messages are used to provide X2 setup by the VRU.

10 . The non-transitory computer-readable medium of claim 8 further comprising instructions wherein the messages are used to add a new call.

11 . The non-transitory computer-readable medium of claim 8 further comprising instructions wherein the messages are used to delete an existing call.

12 . The non-transitory computer-readable medium of claim 8 further comprising instructions wherein exchanging non-content X2 request messages between the VRU and the coordinating server further comprises storing a serving cell for the VRU at a Virtual eNodeB data base (VeNBDB).

13 . The non-transitory computer-readable medium of claim 12 further comprising instructions for updating served cell information for the VRU at a Virtual eNodeB (VeNB).

14 . The non-transitory computer-readable medium of claim 8 wherein the VRU comprises a Centralized Unit (CU) and a Distributed Unit (DU), or a Remote Radio Head (RRH).

15 . A system providing X2 Gateway (GW) multi-cell support, comprising:

a Virtual Radio Unit (VRU) in communication with a Het Net Gateway (coordinating server);

wherein non-content X2 request messages are exchanged between the VRU and the

coordinating server;

wherein non-content X2 response messages are exchanged between the VRU and the

coordinating server; and

wherein the non-content X2 request messages and the X2 response messages are used to communicate multiple cells served by the VRU to the coordinating server.

16 . The system of claim 15 further comprising wherein the messages are used to provide X2 setup by the VRU.

17 . The system of claim 15 further comprising wherein the messages are used to add a new call.

18 . The system of claim 15 further comprising wherein the messages are used to delete an existing call.

19 . The system of claim 15 wherein exchanging non-content X2 request messages between the VRU and the coordinating server wherein a serving cell for the VRU is stored at a Virtual eNodeB data base (VeNBDB).

20 . The system of claim 19 wherein served cell information for the VRU is updated at a Virtual eNodeB (VeNB).
