5. The apparatus of claim 1 , wherein the communication session comprises an Internet Protocol Multimedia Subsystem session.

6. A method for migrating a communication session established between a first entity and a second entity in accordance with an application module operating at an application layer in a communication network, the method comprising the steps of:

obtaining, in a context monitor module executable in accordance with a processor for supporting the application module, context information associated with at least one of the first entity and the second entity from one or more context-specific servers; and

effectuating, in a migration server module executable in accordance with the processor for operating at a session layer supporting the application module, a transfer of the communication session from one communication device associated with the first entity to another communication device associated with the first entity without communication between the one communication device and the other communication device, wherein the transfer of the communication session results in a termination of the communication session on the one communication device and a continuation of the communication session on the other communication device, wherein the transfer does not require reestablishing the communication session between the first entity and the second entity;

wherein the application module determines whether to perform the transfer from one communication device associated with the first entity to the other communication device associated with the first entity of the communication session between the first entity and the second entity based at least in part on the context information obtained by the context monitor module from the one or more context-specific servers;

wherein the context monitor module and the migration server module operate in cooperation with the application module to transfer the communication session; and

wherein the context monitor module, the migration server module, and the application module are implemented other than by the one communication device or the other communication device.

7. The method of claim 6 , wherein the application module receives at least a portion of the context information obtained by the context monitor module.

8. The method of claim 6 , wherein the application module causes the migration server module to effectuate the transfer when the application module determines that the transfer should be performed such that the communication session continues between the first entity and the second entity after the transfer.

9. The method of claim 6 , further comprising the step of obtaining, in a session monitor module supporting the application module, information associated with the communication session, wherein the application module receives at least a portion of the session information for use in making the transfer determination.

10. The method of claim 6 , further comprising the step of obtaining, in one or more support modules, information useable by at least one of the context monitor module and the application module.

11. The method of claim 10 , wherein the one or more support modules comprise a module for storing information pertaining to at least one of a profile and a preference of the first entity.

12. The method of claim 10 , wherein the one or more support modules comprise a module for storing information pertaining to a schedule associated with the first entity.

13. The method of claim 10 , wherein the one or more support modules comprise a module for storing information pertaining to a policy associated with the first entity.

14. The method of claim 10 , wherein the one or more support modules comprise a module for storing information pertaining to a location of one or more communication devices associated with the first entity.

15. The method of claim 10 , wherein the one or more support modules comprise a module for storing information pertaining to a status of one or more communication devices associated with the first entity.

16. Apparatus for migrating a communication session established between a first entity and a second entity in a communication network, the apparatus comprising:

a memory; and

at least one processor coupled to the memory and operative to execute one or more software components that implement:

an application module operating at an application layer;

a context monitor module supporting the application module and operative to obtain context information associated with at least one of the first entity and the second entity from one or more context-specific servers;

a migration server module operating at a session layer supporting the application module and operative to effectuate a transfer of the communication session from one communication device associated with the first entity to another communication device associated with the first entity without communication between the one communication device and the other communication device, wherein the transfer of the communication session results in a termination of the communication session on the one communication device and a continuation of the communication session on the other communication device, wherein the transfer does not require reestablishing the communication session between the first entity and the second entity;

wherein the application module determines whether to perform the transfer from one communication device associated with the first entity to the other communication device associated with the first entity of the communication session between the first entity and the second entity based at least in part on the context information obtained by the context monitor module from the one or more context-specific servers;
