Abstract
In a voice signal relay and transfer method for a voice call between a radio voice terminal and a remote device includes, a radio voice signal is received from the radio voice terminal and converting the radio voice signal into a digital voice signal. The digital voice signal is further converted into a group of voice packets in a streaming form. Then the group of voice packets is transmitted to a streaming server via a mobile communication network. The group of voice packets is further transferred from the streaming server to the remote device in a streaming form.

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.
