Abstract

A system and method for registration of a network access device including a processor configured to identify power loss at a network access device, initiate backup power at the network access device, identify when the backup power at the network access device decreases to or below a first predetermined level, and identify when backup power at the network access device is restored to or above a second predetermined level, and a transmitter configured to transmit, to a server, a registration extension message to reconfigure conditions for handling inbound communications and a registration extension cancellation message to restore original conditions for handling inbound communications.

Claims

1. A method, comprising:

identifying power loss at a network access device;

initiating backup power at the network access device;

identifying when the backup power at the network access device decreases to or below a first predetermined level before the backup power is depleted;

transmitting, to a server, a registration extension message to reconfigure conditions for handling inbound communications associated with the network access device based on the identification of the backup power decreasing to or below the first predetermined level;

identifying when backup power at the network access device is restored to or above a second predetermined level; and

transmitting, to the server, a registration extension cancellation message to restore original conditions for handling inbound communications associated with the network access device based on the identification of the backup power being restored to or above the second predetermined level,

wherein the original conditions for handling inbound communications include forwarding the inbound communication to the network access device and the reconfigured conditions for handling inbound communications include forwarding the inbound communications to a service capable of handling the inbound communications.

2. The method of claim 1, wherein the first predetermined level is set such that the network access device has sufficient power to transmit the registration extension message to reconfigure conditions for handling inbound communications associated with the network access device before the network access device shuts down.

3. The method of claim 1, wherein at least one of the first predetermined level and the second predetermined level are set as a capacity based on time remaining on backup power.

4. The method of claim 1, further comprising determining a level of available backup power by the network access device.

5. The method of claim 1, the transmitting involving Session Initiation Protocol (SIP).

6. The method of claim 1, wherein the network access device includes at least one of an optical network terminal (ONT) and a multi-dwelling unit (MDU) ONT.

7. The method of claim 1, further comprising transmitting one or more messages via a gateway, the gateway selectively receiving one or more messages from the network access device, selectively transmitting one or more messages to the server, selectively receiving one or more acknowledgement messages from the server, and selectively transmitting one or more acknowledgement messages to the network access device.

8. The method of claim 7, wherein the gateway is a session border controller (SBC).

9. The method of claim 1, wherein the server is at least one of an application server and a softswitch.

10. The method of claim 1, wherein the service capable of handling the inbound communications includes at least one of a voicemail service and an alert service.

11. A non-transitory computer readable medium comprising code which when executed causes a computer to perform the method of claim 1.

12. A method, comprising:

receiving, from a network access device, a registration extension message to reconfigure conditions for handling inbound communications when the backup power at the network access device decreases to or below a first predetermined level before the backup power is depleted;

reconfiguring, at a server, conditions for handling inbound communications based on the registration extension message;

receiving, from the network access device, a registration extension cancellation message to restore original conditions for handling inbound communications when backup power at the network access device is restored to or above a second predetermined level, wherein the original conditions for handling inbound communications include forwarding the inbound communication to the network access device and the reconfigured conditions for handling inbound communications include forwarding the inbound communications to a service capable of handling the inbound communications; and

restoring, at the server, conditions for handling inbound communications based on the registration extension cancellation message.

13. The method of claim 12, the transmitting involving Session Initiation Protocol (SIP).

14. The method of claim 12, wherein the first predetermined level is set such that the network access device has sufficient power to transmit the registration extension message to reconfigure conditions for handling inbound communications associated with the network access device before the network access device shuts down.

15. The method of claim 12, wherein at least one of the first predetermined level and the second predetermined level are set as a capacity based on time remaining on backup power.

16. The method of claim 12, further comprising transmitting one or more messages via a gateway, the gateway selectively receiving one or more messages from the network access device, selectively transmitting one or more messages to the application server, selectively receiving one or more acknowledgement messages from the application server, and selectively transmitting one or more acknowledgement messages to the network access device.

17. The method of claim 16, wherein the gateway is a session border controller (SBC).

18. The method of claim 12, wherein the server is at least one of an application server and a softswitch.

19. The method of claim 12, wherein the service capable of handling the inbound communications includes at least one of a voicemail service and an alert service.

20. The method of claim 12, wherein the network access device includes at least one of an optical network terminal (ONT) and a multi-dwelling unit (MDU) ONT.

21. A non-transitory computer readable medium comprising code which when executed causes a computer to perform the method of claim 12.

22. A system, comprising:

a receiver configured to receive, from a network access device, a registration extension message to reconfigure conditions for handling inbound communications when the backup power at the network access device decreases to or below a first predetermined level before the backup power is depleted and a registration extension cancellation message to restore original conditions for handling inbound communications when backup power at the network access device is restored to or above a second predetermined level; and

a processor configured to reconfigure, at a server, conditions for handling inbound communications based on receipt of the registration extension message and restore original conditions for handling inbound communications based on receipt of the registration extension cancellation message,

wherein the original conditions for handling inbound communications include forwarding the inbound communication to the network access device and the reconfigured conditions for handling inbound communications include forwarding the inbound communications to a service capable of handling the inbound communications.

23. The system of claim 22, wherein the first predetermined level is set such that the network access device has sufficient power to reconfigure conditions for handling inbound communications associated with the network access device before the network access device shuts down.

24. The system of claim 22, wherein at least one of the first predetermined level and the second predetermined level are set as a capacity based on time remaining on backup power.
