Abstract

The invention includes a method and apparatus for establishing a call from a caller to a callee. A method includes monitoring call establishment signaling associated with a request by a caller to establish a call from a first terminal of the caller to a first terminal of the callee, determining a location of each of at least one condition in the network, and routing the call establishment signaling to at least one of a second terminal of the caller and a second terminal of the callee based on the location of each of the at least one condition in the network. A method includes monitoring call establishment signaling associated with a request to establish a call from the caller to the callee, and routing the call establishment request signaling from one of a plurality of terminals of the caller toward one of a plurality of terminals of the callee.

Claims

1. A method for establishing a call from a caller to a callee, comprising the steps of:

monitoring call establishment signaling associated with a request by a caller to establish a call from a first terminal of the caller to a first terminal of the callee;

in response to at least one condition in the network, determining a location of each of the at least one condition in the network; and

routing the call establishment signaling to at least one of a second terminal of the caller and a second terminal of the callee based on the location of each of the at least one condition in the network.

2. The method of claim 1, wherein, when the call establishment signaling is routed to the second callee terminal, the step of routing the call establishment signaling comprises the steps of:

identifying the second callee terminal of the callee; and

routing the call establishment signaling toward the identified second callee terminal.

3. The method of claim 2, wherein the step of identifying the second callee terminal comprises the steps of:

determining an identifier of the first callee terminal of the callee; and

querying a database using the first callee terminal identifier to identify the second callee terminal.

4. The method of claim 1, wherein, when the call establishment signaling is routed to the second caller terminal, the step of routing the call establishment signaling comprises the steps of:

identifying the second caller terminal of the caller; and

routing the call establishment signaling toward the identified second caller terminal.

5. The method of claim 4, wherein identifying the second caller terminal comprises the steps of:

determining an identifier of the first caller terminal of the caller; and

querying a database using the first caller terminal identifier to identify the second caller terminal.

6. The method of claim 4, wherein the step of routing the call establishment signaling toward the identified second caller terminal further comprises the step of:

propagating toward the first caller terminal a message indicative of the routing of the call establishment signaling to the second caller terminal.

7. The method of claim 6, wherein the message is presented in human perceptible form at the first caller terminal.

8. An apparatus for establishing a call from a caller to a callee, comprising:

means for monitoring call establishment signaling associated with a request by a caller to establish a call from a first terminal of the caller to a first terminal of the callee;

means for determining a location of each of at least one condition in the network; and

means for routing the call establishment signaling to at least one of a second terminal of the caller and a second terminal of the callee based on the location of each of the at least one condition in the network.

9. The apparatus of claim 8, wherein the means for routing the call establishment signaling comprises:

means for identifying the second callee terminal of the callee; and

means for routing the call establishment signaling toward the identified second callee terminal.

10. The apparatus of claim 9, wherein the means for identifying the second callee terminal comprises:

means for determining an identifier of the first callee terminal of the callee; and

means for querying a database using the first callee terminal identifier to identify the second callee terminal.

11. The apparatus of claim 8, wherein the means for routing the call establishment signaling comprises:

means for identifying the second callee terminal of the callee; and

means for routing the call establishment signaling toward the identified second callee terminal.

12. The apparatus of claim 11, wherein the means for identifying the second caller terminal comprises:

means for determining an identifier of the first caller terminal of the caller; and

means for querying a database using the first caller terminal identifier to identify the second caller terminal.

13. The apparatus of claim 11, wherein the means for routing the call establishment signaling toward the identified second caller terminal comprises:

means for propagating toward the first caller terminal a message indicative of the routing of the call establishment signaling to the second caller terminal.

14. The apparatus of claim 13, wherein the message is adapted to be presented in human perceptible form at the first caller terminal.

15. A method for establishing a call from a caller to a callee, comprising the steps of:

monitoring call establishment signaling associated with a request to establish a call from a first terminal of the caller to a first terminal of the callee; and

in response to at least one condition in the network, routing the call establishment signaling toward a second terminal of the caller.

16. The method of claim 15, wherein the at least one condition in the network comprises at least one condition preventing the call from being established to the first terminal of the caller.

17. The method of claim 15, wherein routing the call establishment signaling toward a second terminal of the caller comprises the steps of:

determining an identifier of the first caller terminal of the caller; and

querying a database using the first caller terminal identifier to identify the second caller terminal.

18. The method of claim 15, further comprising the step of:

propagating toward the first caller terminal a message indicative of attempting to establish the call to the second caller terminal.

19. The method of claim 18, wherein the message is presented in human perceptible form at the first caller terminal.

20. The method of claim 15, further comprising the step of:

in response to the at least one condition in the network, routing the call establishment signaling toward a second terminal of the callee.

21. An apparatus for establishing a call from a caller to a callee, comprising:

means for monitoring call establishment signaling associated with a request to establish a call from a first terminal of the caller to a first terminal of the callee; and

means for routing the call establishment signaling toward a second terminal of the caller in response to at least one condition in the network.

22. The apparatus of claim 21, wherein the at least one condition in the network comprises at least one condition preventing the call from being established to the first terminal of the caller.

23. The apparatus of claim 21, wherein the means for routing the call establishment signaling toward the second terminal of the caller comprises:

means for determining an identifier of the first caller terminal of the caller; and

means for querying a database using the first caller terminal identifier to identify the second caller terminal.

24. The apparatus of claim 21, further comprising:

means for propagating toward the first caller terminal a message indicative of attempting to establish the call to the second caller terminal.

25. The apparatus of claim 24, wherein the message is adapted for being presented in human perceptible form at the first caller terminal.

26. The apparatus of claim 21, further comprising:

means for routing the call establishment signaling toward a second terminal of the callee in response to the at least one condition in the network.

27. A method for establishing a call from a caller to a callee, comprising the steps of:

monitoring call establishment signaling associated with a request to establish a call from the caller to the callee; and

routing the call establishment request signaling from one of a plurality of terminals of the caller toward one of a plurality of terminals of the callee.

28. The method of claim 27, wherein the step of routing the call establishment request signaling comprises the steps of:

routing the call establishment signaling from a first caller terminal toward a first callee terminal; and

in response to an indication that the call establishment signaling cannot be routed from the first caller terminal to the first callee terminal due to at least one network condition, routing the call establishment signaling to at least one of a second caller terminal of the caller and a second callee terminal of the callee.

29. The method of claim 28, wherein routing of the call establishment signaling depends on a location of each of the at least one network condition.
