Abstract

A method is provided in one embodiment and includes receiving a first message including an indication that a first access point of a first network is a gateway access point of a first network, receiving a second message including an indication that a second access point of the first network is an inner access point of the first network, and receiving an indication of a number of wireless devices registered with at least one of the first access point and the second access point. The method further includes determining a power mode for the second access point based upon whether at least one wireless device is registered with the first access point or the second access point, and sending a power mode command message to the second access point indicative of the determined power mode.

Claims

1. A method, comprising:

receiving a first message including an indication that a first access point of a first network is a gateway access point of a first network;

receiving a second message including an indication that a second access point of the first network is an inner access point of the first network;

receiving an indication of a number of wireless devices registered with at least one of the first access point and the second access point;

determining a power mode for the second access point based upon whether at least one wireless device is registered with the first access point or the second access point;

sending a power mode command message to the second access point indicative of the determined power mode;

sending a request for reselection parameters associated with a second network to the first access point;

receiving the reselection parameters from the first access point; and

determining a determined repetition period for a periodic enabling of a transmitter of the second access point when in a reduced power consumption mode based upon the reselection parameters.

2. The method of claim 1, wherein the first message further includes a first network address associated with the first access point.

3. The method of claim 1, wherein the second message further includes a second network address associated with the second access point.

4. The method of claim 1, wherein the first network is a small cell network.

5. The method of claim 1, wherein the first access point is an active entry small cell access point.

6. The method of claim 1, wherein the indication includes an identifier associated with a particular wireless device.

7. The method of claim 1, when there is not at least one wireless device registered with the first access point or the second access point, determining that the power mode for the second access point is a reduced power consumption mode for the second access point.

8. The method of claim 1, when there is at least one wireless device registered with the first access point or the second access point, determining that the power mode for the second access point is an active power consumption mode for the second access point.

9. The method of claim 1, further comprising sending periodic activation information to the second access point, the periodic activation information indicating the determined repetition period.

10. The method of claim 1, wherein the second network is a macro network.

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

receiving a first message including an indication that a first access point of a first network is a gateway access point of a first network;

receiving a second message including an indication that a second access point of the first network is an inner access point of the first network;

receiving an indication of a number of wireless devices registered with at least one of the first access point and the second access point;

determining a power mode for the second access point based upon whether at least one wireless device is registered with the first access point or the second access point;

sending a power mode command message to the second access point indicative of the determined power mode;

sending a request for reselection parameters associated with a second network to the first access point;

receiving the reselection parameters from the first access point; and

determining a determined repetition period for a periodic enabling of a transmitter of the second access point when in a reduced power consumption mode based upon the reselection parameters.

12. The logic of claim 11, wherein the indication includes an identifier associated with a particular wireless device.

13. The logic of claim 11, when there is not at least one wireless device registered with the first access point or the second access point, the operations further include determining that the power mode for the second access point is a reduced power consumption mode for the second access point.

14. The logic of claim 11, when there is at least one wireless device registered with the first access point or the second access point, the operations further include determining that the power mode for the second access point is an active power consumption mode for the second access point.

15. The logic of claim 11, wherein the operations further include sending periodic activation information to the second access point, the periodic activation information indicating the determined repetition period.

16. A network element, comprising:

a memory element configured to store electronic code;

a processor operable to execute instructions associated with the electronic code; and

a module coupled to the memory element and the processor, wherein the network element is configured for;

receiving a first message including an indication that a first access point of a first network is a gateway access point of a first network;

receiving a second message including an indication that a second access point of the first network is an inner access point of the first network;

receiving an indication of a number of wireless devices registered with at least one of the first access point and the second access point;

determining a power mode for the second access point based upon whether at least one wireless device is registered with the first access point or the second access point;

sending a power mode command message to the second access point indicative of the determined power mode;

sending a request for reselection parameters associated with a second network to the first access point;

receiving the reselection parameters from the first access point; and

determining a determined repetition period for a periodic enabling of a transmitter of the second access point when in a reduced power consumption mode based upon the reselection parameters.

17. The network element of claim 16, wherein the indication includes an identifier associated with a particular wireless device.

18. The network element of claim 16, when there is not at least one wireless device registered with the first access point or the second access point, the network element is further configured for determining that the power mode for the second access point is a reduced power consumption mode for the second access point.

19. The network element of claim 16, when there is at least one wireless device registered with the first access point or the second access point, the network element is further configured for determining that the power mode for the second access point is an active power consumption mode for the second access point.

20. The network element of claim 16, wherein the network element is further configured for sending periodic activation information to the second access point, the periodic activation information indicating the determined repetition period.
