Abstract

The present disclosure provides a system and method for shared binding maintenance. In accordance with one example embodiment, there is provided a method for use on a network component for updating bindings, comprising: receiving a Session Initiation Protocol (SIP) message concerning a particular Address-of-Record (AOR); and updating a list of one or more bindings for the particular AOR in a registration repository.

Claims

1. A method for use on a network component for updating bindings, comprising:

receiving a Session Initiation Protocol (SIP) message concerning a particular Address-of-Record (AOR); and

updating a list of one or more bindings for the particular AOR in a registration repository.

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

updating a value of an idle timeout parameter in the registration repository, wherein the idle timeout parameter defines an idle timeout interval.

3. The method of claim 2, wherein the idle timeout interval specifies a time interval in which the list of one or more bindings stored in the registration repository is permitted to remain inactive.

4. The method of claim 2, wherein the idle timeout parameter is a timestamp specifying a time at which the idle timeout interval expires.

5. The method of claim 2, wherein the updating sets the value of the idle timeout parameter to a maximum value of an expiration timeout parameter, wherein the expiration timeout parameter defines an expiration interval that specifies a time interval for which a binding is valid.

6. The method of claim 2, further comprising:

removing a binding in the registration repository for the AOR when the idle timeout interval associated with the list of one or more bindings has expired.

7. The method of claim 6, further comprising:

determining whether the idle timeout interval associated with the list of one or more bindings has expired.

8. The method of claim 1, wherein the updating further comprises updating a logical location of the AOR in the registration repository.

9. The method of claim 1, wherein the registration repository is a distributed cache.

10. A network component, comprising:

a processor configured to receive a Session Initiation Protocol (SIP) message concerning a particular Address-of-Record (AOR), and update a list of one or more bindings for the particular AOR in a registration repository.

11. The network component of claim 10, wherein the updating comprises:

updating a value of an idle timeout parameter in the registration repository, wherein the idle timeout parameter defines an idle timeout interval.

12. The network component of claim 11, wherein the idle timeout interval specifies a time interval in which the list of one or more bindings stored in the registration repository is permitted to remain inactive.

13. The network component of claim 11, wherein the idle timeout parameter is a timestamp specifying a time at which the idle timeout interval expires.

14. The network component of claims 11, wherein the updating sets the value of the idle timeout parameter to a maximum value of an expiration timeout parameter, wherein the expiration timeout parameter defines an expiration interval that specifies a time interval for which a binding is valid.

15. The network component of claim 11, wherein the processor is further configured to remove a binding in the registration repository for the AOR when the idle timeout interval associated with the list of one or more bindings has expired.

16. The network component of claim 15, wherein the processor is further configured to determine whether the idle timeout interval associated with the list of one or more bindings has expired.

17. The network component of claim 10, wherein the updating further comprises updating a logical location of the AOR in the registration repository.

18. The network component of claim 10, wherein the registration repository is a distributed cache.

19. The network component of claim 10, wherein the network component is a SIP registrar server.
