1. A radio network gateway adapted to be used with a radio voice terminal and a remote device, the radio network gateway comprising:
a radio receiving and processing module, receiving a radio voice signal from the radio voice terminal, and converting the radio voice signal into a digital voice signal;
a mobile communication module in communication with the radio receiving and processing module, transmitting a group of voice packets converted from the digital voice signal in a streaming form to the remote device via a mobile communication network;
a signal generator, generating a white noise signal if a voice level of the radio voice signal is lower than a preset threshold; and
a mixer, mixing the radio voice signal with the white noise signal for promoting the voice level before converting the radio voice signal into the digital voice signal.
