Abstract

Aspects of the subject disclosure may include, for example, a communication device that receives a request to update a registration between the communication device and a communication network without causing the communication device to cycle power or reset. The communication device can postpone a process for releasing bearer communications with the communication network responsive to determining that the request to update registration between the communication device and the communication network can be delayed. Other embodiments are disclosed.

First claim

What is claimed is:

1. A wireless communication device, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
initiating communications with a session border controller of a communication network;
receiving from the communication network a request to reattach to the communication network; and
postponing a process for releasing bearer communications with the communication network responsive to detecting an active communication session initiated by the wireless communication device by way of the session border controller and determining that the request to reattach to the communication network is not urgent.

2. The wireless communication device of claim 1 , wherein the operations further comprise initiating the process for releasing bearer communications with the communication network without power cycling the wireless communication device after the active communication session has been terminated.

3. The wireless communication device 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 wireless communication device 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.

5. The wireless communication device of claim 1 , wherein the operations further comprise initiating the process for releasing bearer communications with the communication network during the active communication session responsive to determining that the request to reattach to the communication network is an urgent request.

6. The wireless communication device 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 wireless communication device of claim 6 , wherein the process for attaching to the different session border controller further includes attaching to a call session control function equipment.

8. The wireless communication device 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 wireless communication device.

9. The wireless communication device of claim 8 , wherein the identifying information of the new session border controller is obtained from a Packet Data Network Gateway (PDN-GW) of the communication network using a Protocol Configuration Option (PCO) method.

10. The wireless communication device of claim 8 , 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.

11. The wireless communication device of claim 8 , wherein the operations comprise initiating a process for attaching to the new session border controller.

12. The wireless communication device of claim 11 , wherein the new session border controller serves as a primary session border controller for providing primary communications services, and wherein the new session border controller is paired with a secondary border controller that provides backup communication services.

13. The wireless communication device of claim 8 , wherein a first portion of the communication network comprises an Evolved Packet Core (EPC) network, and wherein a second portion of the communication network comprises an Internet Protocol Multimedia Subsystem (IMS) network.

14. The wireless communication device of claim 13 , wherein the session border controller previously assigned to the wireless communication device and the new session border controller are part of the IMS network.

15. A method, comprising:
initiating, by a wireless communication device, communications with a session border controller of a communication network;
receiving, by the wireless communication device, from the communication network a request to reattach to the communication network; and
postponing, by the wireless communication device, a process for releasing bearer communications with the communication network responsive to detecting an active communication session initiated by the wireless communication device by way of the session border controller and determining that the request to reattach to the communication network is not urgent.

16. The method of claim 15 , further comprising initiating the process for releasing bearer communications with the communication network without power cycling the wireless communication device after the active communication session has been terminated.

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

18. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, comprising:
initiating communications with a session border controller of a communication network;
receiving from the communication network a request to reattach to the communication network; and
postponing a process for releasing bearer communications with the communication network responsive to detecting an active communication session initiated by the processing system by way of the session border controller and determining that the request to reattach to the communication network is not urgent.

19. The non-transitory machine-readable storage medium of claim 18 , further comprising initiating the process for releasing bearer communications with the communication network without power cycling the processing system after the active communication session has been terminated.

20. The non-transitory machine-readable storage medium of claim 18 , further comprising obtaining a random time and initiating the process for releasing bearer communications with the communication network at the random time.
