Abstract
A method and apparatus for hold function control in a mobile terminal are disclosed. The hold function control apparatus includes a controller including a general purpose input/output (GPIO) port, a constant voltage power unit for supplying a preset constant voltage, and a hold key for generating a voltage change at the GPIO port by making an instantaneous electrical contact between the GPIO port and the constant voltage power unit, wherein the controller senses the voltage change generated at the GPIO port. As a result, a hold function cancellation command can be directly recognized through a hardware mechanism, thus reducing the time necessary to cancel the hold function setting.
