Abstract
Systems and methods can be used to reduce power consumption on a device. In some implementations, power consumption can be reduced by powering down modules. In other implementations, power consumption can be reduced by communicating configuration status messages to the terminating system to reduce communications. Power saving can extend backup battery power duration thereby affording users to access telephone services during a power outage.
Claims22
A power saving internet-telephony broadband device, comprising:
- a network interface operable to receive an incoming and send an outgoing signal;
- a power source operable to use a connected external power supply or a backup battery;
- and
- a processor module operable to detect when the connected external power supply is interrupted and subsequently switch to the backup battery, the processor being further operable to power down one or more device modules to conserve battery life, wherein the one or more device modules comprises a selected portion of radio frequency circuitry.
A computer implemented method comprising:
- receiving a primary power loss alert;
- switching to backup battery via a processor;
- powering down one or more modules via a processor, wherein the one or more modules comprises a selected portion of radio frequency circuitry;
- and
- resuming normal operation once external power supply has been restored.
A computer implemented method, comprising:
- receiving a primary power loss alert, the power loss alert indicating loss of an external power supply;
- switching to backup battery via a processor;
- generating a hold-off timer value via a processor;
- comparing the hold-off timer value to a threshold value via a processor;
- reducing the hold-off timer value to the threshold value to minimize data transmission with external devices via a processor;
- and
- resuming normal operation once the external power supply has been restored.
A power saving internet-telephony broadband device, comprising:
- a network interface operable to receive an incoming and send an outgoing signal;
- a power source operable to use a connected external power supply or a backup battery;
- and
- a processor module operable to detect when the connected external power supply is interrupted and subsequently switch to the backup battery, the processor being further operable to power down one or more device modules to conserve battery life, wherein the processor is operable to power down a downstream channel module comprising a radio frequency tuner.
A computer implemented method comprising:
- identifying a primary power loss;
- switching to backup battery via a processor;
- powering down one or more modules via a processor, wherein the powered down one or more modules are selected from the group comprising:
- a selected portion of radio frequency circuitry;
- a selected portion of demodulation circuitry;
- a network processor or auxiliary processor;
- one or more local area network interfaces;
- and
- resuming normal operation once primary power has been restored.
