Hold function control method and apparatus for mobile terminal

摘要

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.

主权项

1. A terminal for controlling a hold function, the terminal comprising:
a controller comprising a general purpose input/output (GPIO) port; a voltage power unit for supplying a voltage; and a hold key for making an electrical connection between the GPIO port and the voltage power unit in response to pressing of the hold key; wherein the controller is configured to: sense a change in the voltage fed to the GPIO port by the electrical connection between the GPIO port and the voltage power unit; recognize first and second inputs of the hold key according to the sensed voltage change; activate, according to the first input of the hold key, hold function for blocking execution of function corresponding to input of at least one of the other keys according to the recognized input; and deactivate, according to the second input of the hold key, hold function.
