Abstract

The disclosure is directed to a mobile communication device, and method for controlling power saving features at the mobile device. A processor in the mobile device may be used to establish a network connection with a server in a first network. The mobile device may also include a transceiver that initiates transmission of a message to the server to determine if an incoming call request has been received via a second network. Advantageously, the transceiver is in a low power mode of operation for a selectable time interval when not communicating with the server.

Claims

1. A mobile communications device, comprising:

a processor configured to establish a network connection with a server; and

a transceiver, in communication with the processor, configured to transmit a message to the server to determine if an incoming call request for the mobile communications device has been received at the server.

2. The mobile communications device of claim 1, wherein the transceiver is further configured to receive a response message from the server via the network connection.

3. The mobile communications device of claim 2, wherein the processor is further configured to establish a communications channel through the network connection with an originator of the incoming call request based on the response message.

4. The mobile communications device of claim 2, wherein the response message includes call set-up information related to the incoming call request.

5. The mobile communications device of claim 1, wherein the incoming call request is one of a data exchange, a voice call, and a text message.

6. The mobile communications device of claim 1, wherein the processor is further configured to change the mobile communications device from a sleep mode of operation to an active mode of operation upon expiration of a predetermined time interval.

7. The mobile communications device of claim 6, wherein the transceiver is further configured to transmit the message to the server when the mobile communications device is in the active mode of operation.

8. The mobile communications device of claim 1, wherein the processor is further configured to establish the network connection with the server via a first network and the incoming call request has been received at the server from a second network.

9. The mobile communications device of claim 6, wherein the processor is further configured to set the predetermined time interval based on input from a user of the mobile communications device.

10. The mobile communications device of claim 6, wherein the transceiver is further configured to be turned off while the mobile communications device is in the sleep mode and to be turned on while the mobile communications device is in the active mode.

11. The mobile communications device of claim 1, wherein the first network comprises a wireless LAN and the second network comprises a cellular network.

12. A mobile communications device, comprising:

a processor configured to operate the mobile communications device in at least an active mode and a sleep mode, said processor further configured to communicate with a server using a first network;

a memory accessible to the processor configured to store a selectable sleep mode interval setting; and

a transceiver, controlled by the processor, configured to transmit a message to the server to determine if an incoming call request for the mobile communications device has been received at the server from a second network, wherein the message is transmitted from the mobile communications during the active mode.

13. The mobile communications device of claim 12, wherein the transceiver is further configured to receive a reply in response to the message, the reply indicating call setup information for the incoming call request.

14. The mobile communications device of claim 13, wherein the processor is further configured to establish a connection with an originator of the incoming call request based on the reply.

15. The mobile communications device of claim 14, wherein the incoming call request is one of a data exchange, a voice call, and a text message.

16. The mobile communications device of claim 12, wherein the processor is further configured to change the mobile communications device from the sleep mode to the active mode upon expiration of the selectable sleep mode interval setting.

17. The mobile communications device of claim 12, wherein the first network comprises a wireless LAN and the second network comprises a cellular network.

18. The mobile communications device of claim 12, wherein said setting is configurable by a user of the mobile communications device.

19. A communications system comprising:

a server configured to store data for a mobile communications device;

a mobile communications device, in communication with the server, comprising;

a processor configured to operate the mobile communications device in at least a sleep mode for a predetermined duration and an active mode, and

a transceiver, controlled by the processor, configured to transmit a message to the server upon expiration of the predetermined duration to indicate the mobile communications device is in the active mode; and

wherein the server, in response to receiving the message, is further configured to transmit the data to the mobile communications device.

20. The system of claim 19, wherein the transceiver is further configured to be turned off during the sleep mode and configured to be turned on during the active mode.

21. The system of claim 19, wherein the mobile communications device and the server communicate via a first network and the data is received at the server via a second network.

22. The system of claim 21, wherein the first network comprises a wireless LAN and the second network comprises a cellular network.

23. The system of claim 22, wherein the data is received at the server at a first, data rate and the data is transmitted to the transceiver at a second data rate.

24. The system of claim 22, wherein the processor is further configured to change the mobile communications device to a sleep mode of operation for a predetermined time interval after the transceiver has received the data.

25. A mobile communications device, comprising:

means for establishing a network connection with a server via a first network; and

means for transmitting a message to the server to determine if an incoming call request for the mobile communications device has been received at the server from a second network.

26. A mobile communications device comprising:

means for establishing a network connection with a server via a first network, the server storing buffered data for transmission to the mobile communications device;

said buffered data received at the server via a second network; and

means for transmitting a message to the server to indicate the mobile communications device is in an operating mode able to receive data from the server.

27. A method for conserving power of a mobile communications device comprising the steps of:

establishing a network connection between the mobile communications device and a server; and

transmitting a message to the server to determine if an incoming call request for the mobile communications device has been received at the server.

28. The method according to claim 27, further comprising the step of:

in response to the message, receiving from the server call set-up information related to the incoming call request.

29. The method according to claim 27, wherein the message is transmitted via a first network and the incoming call request is received via a second network.

30. The method according to claim 29;

wherein the first network comprises a wireless LAN and the second network comprises a cellular network.

31. The method according to claim 27, further comprising the step of:

establishing a voice call, through the server, with an originator of the incoming call request.
