Abstract

Systems and methods to monitor and analyze customer premises equipment downtime in a Voice over Internet Protocol service network are disclosed. Example methods for a dynamic host configuration protocol server disclosed herein include assigning a replacement Internet protocol address to a residential gateway, the replacement Internet protocol address to replace a first Internet protocol address assigned to at least one of the residential gateway or customer premises equipment associated with the residential gateway, sending a first address change message to a session border controller, and sending a second address change message to a lost subscriber time server, the first and second address change messages to indicate that the first Internet protocol address has been replaced by the replacement Internet protocol address.

Claims

1. A method for a dynamic host configuration protocol server, the method comprising:

assigning a replacement Internet protocol address to a residential gateway, the replacement Internet protocol address to replace a first Internet protocol address assigned to at least one of the residential gateway or customer premises equipment associated with the residential gateway;

sending a first address change message to a session border controller; and

sending a second address change message to a lost subscriber time server, the first and second address change messages to indicate that the first Internet protocol address has been replaced by the replacement Internet protocol address.

2. A method as defined in claim 1, wherein assigning the replacement Internet protocol address to the residential gateway occurs prior to sending the first and second address change messages.

3. A method as defined in claim 1, wherein the first and second address change messages each include the first Internet protocol address and the replacement Internet protocol address.

4. A method as defined in claim 1, wherein the session border controller includes at least one of an Internet protocol multimedia subsystem access border element or a proxy call session control function server.

5. A method as defined in claim 1, wherein assigning the replacement Internet protocol address to the residential gateway occurs in response to receiving a request to renew an Internet protocol address license.

6. A method as defined in claim 1, wherein the first address change message is sent to the session border controller before the customer premises equipment performs a next registration with a service provider network.

7. A dynamic host configuration protocol server comprising:

a memory to store machine readable instructions; and

a processor responsive to the instructions to perform operations comprising;

assigning a replacement Internet protocol address to a residential gateway, the replacement Internet protocol address to replace a first Internet protocol address assigned to at least one of the residential gateway or customer premises equipment associated with the residential gateway;

sending a first address change message to a session border controller; and

sending a second address change message to a lost subscriber time server, the first and second address change messages each to indicate that the first Internet protocol address has been replaced by the replacement Internet protocol address.

8. A dynamic host configuration protocol server as defined in claim 7, wherein the operations further comprise assigning the replacement Internet protocol address prior to sending the first and second address change messages.

9. A dynamic host configuration protocol server as defined in claim 7, wherein the first and second address change messages each include the first Internet protocol address and the replacement Internet protocol address.

10. A dynamic host configuration protocol server as defined in claim 7, wherein the session border controller includes at least one of an Internet protocol multimedia subsystem access border element or a proxy call session control function server.

11. A dynamic host configuration protocol server as defined in claim 7, wherein the operations further comprise assigning the replacement Internet protocol address to the residential gateway occurs in response to receiving a request to renew an Internet protocol address license.

12. A dynamic host configuration protocol server as defined in claim 7, wherein the processor is to send the first address change message to the session border controller before the customer premises equipment performs a next registration with a service provider network.

13. A dynamic host configuration protocol server as defined in claim 7, wherein the memory is to store a plurality of non-assigned Internet protocol addresses and a plurality of assigned Internet protocol addresses.

19. A storage medium as defined in claim 13, wherein the machine readable instructions cause the machine to send the first address change message to the session border controller before the customer premises equipment performs a next registration with a service provider network.

14. A tangible machine readable storage medium having machine readable instructions stored thereon that, when executed, cause a machine to perform operations comprising:

assigning a replacement Internet protocol address to a residential gateway, the replacement Internet protocol address to replace a first Internet protocol address assigned to at least one of the residential gateway or customer premises equipment associated with the residential gateway;

sending a first address change message to a session border controller; and

sending a second address change message to a lost subscriber time server, the first and second address change messages to indicate that the first Internet protocol address has been replaced by the replacement Internet protocol address.

15. A storage medium as defined in claim 14, wherein assigning the replacement Internet protocol address to the residential gateway occurs prior to sending the first and second address change messages.

16. A storage medium as defined in claim 14, wherein the first and second address change messages each include the first Internet protocol address and the replacement Internet protocol address.

17. A storage medium as defined in claim 14, wherein the session border controller includes at least one of an Internet protocol multimedia subsystem access border element or a proxy call session control function server.

18. A storage medium as defined in claim 14, wherein assigning the replacement Internet protocol address to the residential gateway occurs in response to receiving a request to renew an Internet protocol address license.
