Abstract

A method is provided in one example embodiment and includes detecting user plane congestion at an eNodeB in connection with subscribers of a first one of a plurality of public land management networks (“PLMNs”) sharing a radio access network (“RAN”), identifying one or more of the PLMNs to be notified of the detected congestion in accordance with an agreement between the PLMNs, and reporting RAN congestion information (“RCI”) regarding the detected congestion to only the identified one or more of the PLMNs. The detecting may comprise determining whether detected user plane congestion exceeds a first congestion threshold indicated for the first one of the PLMNs. The method may further comprise terminating the RCI reporting when the detected congestion falls below a second congestion threshold specified for the first one of the PLMNs. The first and second thresholds may be indicated in a table associated with the eNodeB.

Claims

1. A method, comprising:

detecting user plane congestion at an eNodeB in connection with subscribers of a first one of a plurality of public land management networks (“

PLMNs”

) sharing a radio access network (“

RAN”

);

identifying one or more of the PLMNs to be notified of the detected congestion in accordance with an agreement between the PLMNs;

reporting RAN congestion information (“

RCI”

) regarding the detected congestion to only the identified one or more of the PLMNs.

2. The method of claim 1, wherein the detecting comprises:

determining whether detected user plane congestion exceeds a first congestion threshold indicated for the first one of the PLMNs.

3. The method of claim 2, wherein the first congestion threshold is indicated in a table associated with the eNodeB.

4. The method of claim 1 further comprising:

terminating the RCI reporting when the detected congestion falls below a second congestion threshold specified for the first one of the PLMNs.

5. The method of claim 2, wherein the second congestion threshold is indicated in a table associated with the eNodeB.

6. The method of claim 1, wherein the identified one or more of the PLMNs comprises the first one of the PLMNs.

7. The method of claim 1, wherein the identified one or more of the PLMNs comprises an owner of the RAN.

8. The method of claim 1, wherein the agreement comprises a Service Level Agreement (“

SLA”

).

9. The method of claim 1, wherein the identifying comprises referring to an entry in a table associated with the eNodeB, wherein the entry corresponds to the first one of the PLMNs.

10. Logic encoded in one or more non-transitory tangible media that includes code for execution and when executed by a processor is operable to perform operations comprising:

detecting user plane congestion at an eNodeB in connection with subscribers of a first one of a plurality of public land management networks (“

PLMNs”

) sharing a radio access network (“

RAN”

);

identifying one or more of the PLMNs to be notified of the detected congestion in accordance with an agreement between the PLMNs;

reporting RAN congestion information (“

RCI”

) regarding the detected congestion to only the identified one or more of the PLMNs.

11. The logic of claim 10, wherein the detecting comprises:

determining whether detected user plane congestion exceeds a first congestion threshold indicated for the first one of the PLMNs.

12. The logic of claim 10 further operable to perform operations comprising:

terminating the RCI reporting when the detected congestion falls below a second congestion threshold specified for the first one of the PLMNs.

13. The logic of claim 10, wherein the identified one or more of the PLMNs comprises at least one of the first one of the PLMNs and an owner of the RAN.

14. The logic of claim 10, wherein the identifying comprises referring to an entry in a table associated with the eNodeB, wherein the entry corresponds to the first one of the PLMNs.

15. An apparatus comprising:

a memory element configured to store data;

a processor operable to execute instructions associated with the data; and

a RCI reporting module configured to;

detect user plane congestion at an eNodeB in connection with subscribers of a first one of a plurality of public land management networks (“

PLMNs”

) sharing a radio access network (“

RAN”

);

identify one or more of the PLMNs to be notified of the detected congestion in accordance with an agreement between the PLMNs; and

report RAN congestion information (“

RCI”

) regarding the detected congestion to only the identified one or more of the PLMNs.

16. The apparatus of claim 15, wherein the detecting comprises:

determining whether detected user plane congestion exceeds a first congestion threshold indicated for the first one of the PLMNs.

17. The apparatus of claim 15, wherein the RCI reporting module is further configured to terminate the RCI reporting when the detected congestion falls below a second congestion threshold specified for the first one of the PLMNs.

18. The apparatus of claim 15, wherein the identified one or more of the PLMNs comprises the first one of the PLMNs.

19. The apparatus of claim 15, wherein the identified one or more of the PLMNs comprises an owner of the RAN.

20. The apparatus of claim 15, wherein the identifying comprises referring to an entry in a table associated with the eNodeB, wherein the entry corresponds to the first one of the PLMNs.
