Abstract

Methods and systems are described herein for adaptively adjusting the power level of a wireless transceiver and a cellular transceiver in a telecommunications device to correspond to the usage and data throughput of the device. The device can also dynamically enter different modes of operation based at least in part on network activity data usage on a wireless data network provided by the telecommunications device. By controlling the power levels, the power usage of the device can be reduced in order to increase efficiency of battery usage.

Claims (47)

1. A computer-implemented method for power management, the computer-implemented method comprising:

communicating, by a mobile device, with a cellular network via a cellular transceiver;

communicating, by a mobile device, with at least one client device via a wireless data network, wherein access to the wireless data network is provided by the mobile device via a wireless transceiver, wherein the wireless data network is a non-cellular network, wherein data is communicated between the cellular network and the wireless data network via the mobile device;

determining a cellular condition of the mobile device associated with communication between the mobile device and the cellular network;

determining a cellular network data rate for the mobile device based at least in part on the cellular condition, wherein the cellular network data rate is between the mobile device and the cellular network;

determining a wireless data network data rate of the at least one client device communicating with the mobile device, wherein the wireless network data rate is between the mobile device and the at least one client device over the wireless data network;

comparing the cellular network data rate with the wireless data network data rate;

based on the determination that the cellular network data rate exceeds the wireless data network data rate,

determining a power level for the cellular transceiver corresponding the wireless data network data rate; and

adjusting a cellular transceiver power level to the determined power level.

2. The computer-implemented method of claim 1 , further comprising:

based on the determination that the wireless data network data rate exceeds the cellular network data rate,

determining a power level for the wireless transceiver corresponding to the cellular network data rate; and

adjusting a wireless transceiver power level to the determined power level.

3. The computer-implemented method of claim 1 , wherein the cellular network data rate comprises a predictive data rate.

4. The computer-implemented method of claim 1 , wherein the cellular network data rate is based at least in part on time of day.

5. The computer-implemented method of claim 1 , wherein the cellular network data rate is based at least in part on a movement speed of the mobile device.

6. The computer-implemented method of claim 2 , further comprising:

detecting a change in the wireless data network data rate; and

adjusting the power level of at least one of the wireless transceiver or the cellular transceiver to account for the change.

7. The computer-implemented method of claim 1 , further comprising:

detecting a change in the cellular network data rate; and

adjusting the power level of at least one of the wireless transceiver and the cellular transceiver to account for the change.

8. The computer-implemented method of claim 1 , wherein the cellular condition comprises a channel quality index.

9. The computer-implemented method of claim 1 , wherein the cellular condition comprises a fading index.

10. The computer-implemented method of claim 1 , wherein the cellular network data rate is an uplink data rate.

11. The computer-implemented method of claim 1 , wherein the cellular network data rate is a downlink data rate.

12. A mobile telecommunications device comprising:

a cellular transceiver configured to communicate with a cellular network;

a wireless transceiver configured to provide a wireless data network, wherein the wireless data network is a non-cellular network, wherein data is communicated between the cellular network and the wireless data network via the mobile telecommunications device; and

a processing unit in communication with memory and a network interface, the processing unit configured to:

communicate, over the wireless data network, with at least one client device via the network interface;

determine a cellular condition;

determine a cellular network data rate based at least in part on the cellular condition, wherein the cellular network data rate is between the mobile device and the cellular network;

determine a wireless data network data rate of communication between the at least one client device and the mobile communications device, wherein the wireless network data rate is between the mobile device and the at least one client device over the wireless data network;

compare the cellular network data rate with the wireless data network data rate;

based on the determination that the cellular network data rate exceeds the wireless data network data rate,

determine a power level for the cellular transceiver corresponding the wireless data network data rate; and

cause adjustment of a cellular transceiver power level to the determined power level.

13. The mobile telecommunications device of claim 12 , wherein the mobile telecommunications device is battery powered.

14. The mobile telecommunications device of claim 13 , wherein the processing unit is further configured to:

based on the determination that the wireless data network data rate exceeds the cellular network data rate,

determine a power level for the wireless transceiver corresponding to the cellular network data rate; and

adjust a wireless transceiver power level to the determined power level.

15. The mobile telecommunications device of claim 12 , wherein the wireless data network is a wireless data network based on the family of IEEE 802.11 technical standards.

16. The mobile telecommunications device of claim 12 , wherein the processing unit causes an increase in the power level of the cellular transceiver.

17. The mobile telecommunications device of claim 12 , wherein the processing unit causes a decrease in the cellular transceiver power level.
