Abstract

A system, method, device, and computer program that provide a power management profile for a mobile communication device. The system includes a base station and a mobile communication device in communication with the base station. After the device, receives a power conservation initiation signal, the device initiates a power conservation profile in which one or more of the following actions may be taken: 1) reduce the frequency that the device registers with the base station; 2) switch the device to a messaging only mode; 3) disconnect the device from the base station after receiving messages; and 4) switch the device into “sleep” mode after disconnecting the device from the base station. The messaging only mode may comprise sending and receiving communications through SMS, MMS, IM, or e-mail.

switching the device to a messaging only mode, at the device, in response to receiving the power conservation initiation signal.

2. The method of claim 1, wherein the messaging only mode is a messaging type selected from the group consisting of short messaging service, multimedia messaging service, instant messaging, and e-mail.

3. The method of claim 1, wherein initiating a power conservation profile comprises:

receiving messages at the device sent from the base station;

disconnecting the device from the base station after receiving the messages; and

switching the device to sleep mode at the device after disconnecting the device from the base station.

4. The method of claim 1, wherein the power conservation initiation signal is generated by a user of the device.

5. The method of claim 1, wherein the power conservation initiation signal is generated in response to the power level of the device being lower than a predetermined threshold.

6. The method of claim 1, further comprising:

receiving a call at a network server, the call sent to the device from a caller; and

sending the caller a message from the network server, the message indicating the device is in messaging only mode.

7. The method of claim 6, wherein messaging only mode is a messaging type selected from the group consisting of short messaging service, multimedia messaging service, instant messaging, and e-mail.

8. The method of claim 6, wherein the message is of a message type selected from the group consisting of short messaging service, multimedia messaging service, instant messaging, e-mail, and voicemail.

9. The method of claim 6, further comprising:

selecting a contact preference at the device;

sending the contact preference from the device to the base station;

sending the contact preference from the base station to the network server; and

storing the contact preference at the network server.

10. The method of claim 9, wherein the message further comprises the contact preference for the device.

11. The method of claim 10, wherein the contact preference is a messaging type selected from the group consisting of short messaging service, multimedia messaging service, instant messaging, and e-mail.

12. A computer program product for managing the power usage of a mobile communication device comprising:

computer code configured to;

initiate a power conservation profile in response to receiving a power conservation initiation signal wherein the power conservation profile initiation comprises;

reducing the frequency of registering the device with a base station in response to the power conservation initiation signal; and

switching the device to a messaging only mode in response to the power conservation initiation signal.

13. The computer program product of claim 12, wherein the messaging only mode is a messaging type selected from the group consisting of short messaging service, multimedia messaging service, instant messaging, and e-mail.

14. The computer program product of claim 12, wherein the power conservation profile initiation comprises:

registering the device with the base station;

receiving messages sent from the base station; and

disconnecting the device from the base station after receiving the messages.

15. The computer program product of claim 14, wherein the power conservation profile initiation further comprises switching the device to sleep mode after disconnecting the device from the base station.

16. The computer program product of claim 12, wherein the computer code is further configured to send a contact preference from the device to a network server.

17. The computer program product of claim 16, wherein the contact preference is a messaging type selected from the group consisting of short messaging service, multimedia messaging service, instant messaging, and e-mail.

18. The computer program product of claim 12, wherein the computer code is further configured to generate the power conservation initiation signal when the power level of the device is lower than a predetermined threshold.
