Abstract

A method of gracefully shutting down a mobile device in operational relationship with one or more active components is provided. The method comprises monitoring the mobile device'"'"'s status; forwarding a termination message to at least one of the active components, when it is determined that the mobile device'"'"'s status is changed from a first position to a second position; and terminating operation of the at least one active component, prior to the mobile device'"'"'s status changing to the second position.

Claims

1. A method for gracefully shutting down a mobile device, the method comprising:

monitoring the mobile device'"'"'s status as to whether the mobile device is being fully powered off;

forwarding from the mobile device a first termination message to at least one network device when it is determined that the mobile device is being fully powered off, wherein the network device discontinues communicating with the mobile device according to instructions provided in the first termination message to prevent data loss and indefinite allocation of resources;

forwarding from the mobile device a second termination message to at least one active component when it is determined that the mobile device is being fully powered off, wherein operation of the active component is terminated according to instructions provided in the second termination message to prevent data loss and indefinite allocation of resources; and

fully powering off the mobile device, wherein no data loss or indefinite allocation of resources occurs in the active component, the network device, and the mobile device,

wherein the mobile device connects the network device, which is in a personal area wireless communication network, to a wireless area network so that the network device can communicate with devices in the wireless area network; and

wherein the active component comprises a software or hardware module in communication with the mobile device.

2. The method of claim 1, wherein the active component comprises a software application executed on the mobile device.

3. The method of claim 1, wherein the active component comprises a processor chip.

4. The method of claim 1, wherein the active component comprises a memory chip.

5. The method of claim 1, wherein the active component comprises a communication session established between the mobile device and another device.

6. The method of claim 1, further comprising:

waiting to receive an acknowledgement message from said at least one active component or network device, prior to terminating the operation of the at least one active component.

7. The method of claim 1, further comprising:

forwarding a plurality of termination messages to the at least one active component or network device, prior to mobile device being fully powered off.

8. The method of claim 7, wherein the acknowledgement message indicates that the active component or the network device has received the termination message.

9. The method of claim 1, wherein the mobile device is a cellular telephone.

10. The method of claim 1, wherein the first termination message instructs the network device to shutdown.

11. The method of claim 10, wherein the network device forwards an acknowledgement message to the mobile device upon receipt of the first termination message.

12. A system for gracefully shutting down a mobile device, the system comprising:

means for monitoring the mobile device'"'"'s status as to whether the mobile device is being fully powered off;

means for forwarding from the mobile device a first termination message to at least one network device when it is determined that the mobile device is being fully powered off, wherein the network device discontinues communicating with the mobile device according to instructions provided in the first termination message to prevent data loss and indefinite allocation of resources;

means for forwarding from the mobile device a second termination message to at least one active component when it is determined that the mobile device is being fully powered off, wherein operation of the active component is terminated according to instructions provided in the second termination message to prevent data loss and indefinite allocation of resources; and

means for fully powering off the mobile device, wherein no data loss or indefinite allocation of resources occurs in the active component, the network device, and the mobile device,

wherein the mobile device connects the network device, which is in a personal area wireless communication network, to a wireless area network so that the network device can communicate with devices in the wireless area network; and

wherein the active component comprises a software or hardware module in communication with the mobile device.

13. The system of claim 12, wherein the active component comprises a software application executed on the mobile device.

14. The system of claim 12, wherein the active component comprises a processor chip.

15. The system of claim 12, wherein the active component comprises a memory chip.

16. The system of claim 12, wherein the active component comprises a communication session established between the mobile device and another device.

17. The system of claim 12, further comprising:

means for receiving an acknowledgement message from said at least one active component or network device, prior to terminating the operation of the at least one active component.
