Abstract

Aspects of the subject disclosure may include, for example, a system that detects a request to reattach to a communication network to update a registration between a wireless communication system and the communication network while the wireless communication system is connected to a session border controller of the communication network. The system delays a release of bearer communications with the communication network responsive to the request to reattach to the communication network not being urgent. Other embodiments are disclosed.

First claim

What is claimed is:

1. A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
receiving a request to reattach to a communication network to update a registration between a communication device and the communication network while the communication device is connected to a session border controller of the communication network; and
postponing a process, by the communication device, for releasing bearer communications with the communication network responsive to determining that the request to reattach to the communication network is not urgent.

2. The machine-readable storage medium of claim 1 , wherein the postponing is further responsive to detecting an active communication session initiated by the communication device via the session border controller.

3. The machine-readable storage medium of claim 1 , wherein the operations further comprise obtaining a random time and initiating the process for releasing bearer communications with the communication network at the random time.

4. The machine-readable storage medium of claim 1 , wherein the operations further comprise initiating the process for releasing bearer communications with the communication network at a time provided in the request.

5. The machine-readable storage medium of claim 1 , wherein the operations further comprise initiating the process for releasing bearer communications with the communication network at a time provided in the request supplied by the communication network.

6. The machine-readable storage medium of claim 1 , wherein the operations further comprise initiating a process for attaching to a different session border controller selected by the communication network.

7. The machine-readable storage medium of claim 1 , wherein the operations further comprise obtaining from the communication network identifying information for a new session border controller that differs from the session border controller previously assigned to the communication device.

8. A method, comprising:
detecting, by a wireless communication system operating from a processing system including a processor, a request to reattach to a communication network to update a registration between a communication device and the communication network while the communication device is connected to a session border controller of the communication network; and
postponing, by the processing system, a process that releases bearer communications of the communication device with the communication network responsive to a determination that the request to reattach to the communication network is not urgent.

9. The method of claim 8 , wherein the postponing is further responsive to detecting, by the processing system, an active communication session initiated by the communication device via the session border controller.

10. The method of claim 8 , further comprising:
obtaining, by the processing system, a random time and initiating the process for releasing bearer communications with the communication network at the random time.

11. The method of claim 8 , further comprising:
initiating, by the processing system, the process that releases bearer communications with the communication network at a time provided in the request.

12. The method of claim 8 , further comprising:
initiating the process for releasing bearer communications with the communication network at a time provided in the request supplied by the communication network.

13. The method of claim 8 , further comprising:
initiating a process for attaching to a different session border controller selected by the communication network.

14. The method of claim 8 , further comprising:
obtaining from the communication network identifying information for a new session border controller that differs from the session border controller previously assigned to the communication device.

15. A system, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
detecting a request to reattach to a communication network to update a registration between a wireless communication system and the communication network while the wireless communication system is connected to a session border controller of the communication network; and
delaying a release of bearer communications with the communication network responsive to the request to reattach to the communication network not being urgent.

16. The system of claim 15 , wherein the delaying is further responsive to detecting an active communication session initiated by the wireless communication system via the session border controller.

17. The system of claim 15 , wherein the operations further comprise obtaining a random time and initiating the process for releasing bearer communications with the communication network at the random time.

18. The system of claim 15 , wherein the operations further comprise initiating the process for releasing bearer communications with the communication network at a time provided in the request.

19. The system of claim 15 , wherein the operations further comprise obtaining from the communication network identifying information for a new session border controller that differs from the session border controller previously assigned to the wireless communication system.

20. The system of claim 19 , wherein the session border controller is paired with a second session border controller to form a first georedundant pair of session border controllers, wherein the new session border controller is paired with a third session border controller to form a second georedundant pair of session border controllers, and wherein the operations further comprise initiating an attachment to the second georedundant pair of session border controllers.
