Abstract

At least one example embodiment discloses a system including a plurality of base stations. The system further includes a proxy server configured to generate a request for loading information from at least one of the plurality of base stations and receive the loading information from the at least one of the plurality of base stations, the request being a base station to base station interface message.

Claims (22)

1. A system including a plurality of base stations, the system comprising:

a proxy server configured to generate a request for loading information from at least one of the plurality of base stations and receive the loading information from the at least one of the plurality of base stations, the request being a base station to base station interface message, wherein the proxy server is configured to receive Resource Status Request Messages from the plurality of base stations, respectively, and transmit a response to each received status request message, the response indicating zero resources to support calls and receive handoff attempts in at least one of a Hardware Load set to overload, an S1 Transport Network Load set to overload and a Radio Resource Status indicating a maximum usage.

2. The system of claim 1 , wherein the proxy server is configured to invoke a Resource Status Initiation procedure defined in 3GPP TS 36.423 to generate the request for loading information.

3. The system of claim 2 , wherein the proxy server is configured to generate a Resource Status Request Message as the request.

4. The system of claim 3 , wherein the generated Resource Status Request message indicates a rate for the at least one of the plurality of base stations to transmit the loading information.

5. The system of claim 1 , wherein the proxy server is configured to communicate with the plurality of base stations over 3GPP X2 interfaces.

6. The system of claim 1 , wherein the proxy server is configured to transmit the loading information to at least one of Yield Management, Network Optimization and Application Optimization application servers.

7. The system of claim 1 , wherein the proxy server is configured to generate the request periodically.

8. The system of claim 1 , wherein the proxy server is configured to receive the loading information in a Resource Status Update message.

9. The system of claim 8 , wherein the received Resource Status Update message includes at least one of a hardware load indicator, an S1 transport network load indicator, a radio resource status, a composite available capability group and Almost Blank Subframe (ABS) information.

10. The system of claim 1 , wherein the base station to base station interface message is a standardized 3GPP X2 interface message.

11. A method of obtaining loading information from at least one of a plurality of base stations in a system, the method comprising:

generating, by a proxy server, a Resource Status Request message for the loading information from at least one of the plurality of base stations, the Resource Status Request message being a base station to base station interface message;

receiving, by the proxy server, a Resource Status Update message, the Resource Status Update message including the loading information from the at least one of the plurality of base stations, the Resource Status Update message being a base station to base station interface message;

receiving a Resource Status Request Message from at least one of the plurality of base stations; and

transmitting a response to each received Resource Status Request Message, the response indicating zero resources to support calls and receive handoff attempts in at least one of a Hardware Load set to overload, an S1 Transport Network Load set to overload and a Radio Resource Status indicating a maximum usage.

12. The method of claim 11 , wherein the generated Resource Status Request message indicates a rate for the at least one of the plurality of base stations to transmit the loading information.

13. The method of claim 11 , wherein the proxy server receives the Resource Status Update message over a 3GPP X2 interface.

14. The method of claim 11 , further comprising:

transmitting the loading information to at least one of Yield Management, Network Optimization and Application Optimization application servers.

15. The method of claim 11 , wherein the received Resource Status Update message includes at least one of a hardware load indicator, an S1 transport network load indicator, a radio resource status, a composite available capability group and Almost Blank Subframe (ABS) information.

16. The method of claim 11 , wherein the generated Resource Status Request message and the received Resource Status Update message are 3GPP standardized messages.
