Provided is a portable device using a digital walkie-talkie module, which includes: a radio frequency unit which forms a call channel based on a mobile communications system; a digital walkie-talkie module which forms a communications channel based on a public frequency band; an input unit which generates an input signal for activation of at least one of the radio frequency unit and the digital walkie-talkie module; an audio processing unit which outputs at least one of an audio signal received by the radio frequency unit and an audio signal received by the digital walkie-talkie module, and collects an inputted audio signal and sends the collected audio signal to one of the radio frequency unit and the digital walkie-talkie module; and a controller which controls processing of a digital signal sent from the digital walkie-talkie module and outputs the processed digital signal to the audio processing unit, or to process an inputted audio signal and send the processed audio signal to the digital walkie-talkie module.
Description
technical field [0001] The present invention relates to portable devices, and more particularly, to a portable device including a digital walkie-talkie module and a control method thereof. Background technique [0002] Portable devices are one of rapidly developing electronic products due to their simplicity and convenience. Recently, various options that can store and play information desired by portable device users, such as MP3 functions, DMB functions, video playback functions, and camera functions, have been added to portable devices to further increase their convenience. In combination with mobile communication functionality, these portable devices can provide the ability to communicate with other portable device users. However, among portable device functions, a mobile communication function is designed to use a telecommunication network. Therefore, according to the use of mobile communication services, a certain fee is paid to the service provider who establishes t...
