Abstract

A system that enhances life of a battery in cell phone devices that work in conjunction with a cellular telephone network has a Registration-Request Signal transmission management function that operates in the device and periodically detects change in physical location of the device from an immediate prior location, called an LchangeDelta. The function, if the LchangeDelta is below a threshold of change in location, suppresses an Registration-Request Signal transmission from the device to the cellular network, thus enhancing battery life.
