PORTABLE DEVICE INCLUDING A DIGITAL WALKIE-TALKIE MODULE
First Claim
1. A portable device using a digital walkie-talkie module, the portable device comprising:
- 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 to process a digital signal sent from the digital walkie-talkie module and output the processed digital signal to the audio processing unit, or controls to process an inputted audio signal and send the processed audio signal it to the digital walkie-talkie module.

6. A method of controlling a portable device including a radio frequency unit forming a call channel based on a mobile communications system and a digital walkie-talkie module forming a communications channel based on a public frequency band, the method comprising:
-
forming a call channel based on the radio frequency unit; forming a communications channel by performing a frequency setting for the communications channel formation, in case an input signal for activation of the digital walkie-talkie module based communications channel is generated during the call channel formation; and processing a signal transmitted and received through the digital walkie-talkie module by a signal processing unit which processes a signal transmitted and received through the radio frequency unit. - View Dependent Claims (7, 8, 9, 10, 11)
