Abstract

Disclosed is a mechanism that enables a smart phone or other mobile device to suspend searching for a cell tower connection when it is in a known dead zone, until the device changes location and possibly leaves the dead zone.

One of the more common complaints about smart phones is battery life. In many instances, devices consume power when performing active work (e.g., making a phone call, surfing the web, playing a game, etc.) In some instances, however, devices needlessly consume power. One such instance is continually searching for a cell tower connection in an area that has a historically weak or non-existent cell signal (i.e. a dead zone).

Several mechanisms exist to resolve this problem. The first is for the user to manually switch the device into "airplane mode". This action certainly conserves power, but it also puts the burden on the user to remember not only to switch the device into airplane mode when located in a dead zone, but also to switch out of airplane mode when leaving the dead zone.

Additionally, several applications (apps) exist that partially solve this problem by detecting the lack of a cell signal and automatically switching the device into "airplane" mode for a predefined period of time, then waking up and checking for a cell signal and either going back into airplane mode or not. This approach works, but "polling" (periodically waking up to check for a cell signal) is not very power efficient.

The solution presented herein is a mechanism that enables a smart phone or other mobile device to, upon determining it is in a "dead zone," suspend searching for a cell tow...
