Voice signal relay and transfer method for calls
The granted patent US12075005B2 outlines a radio network gateway designed to facilitate communication between a radio voice terminal and a remote device. The gateway features a radio receiving and processing module that converts incoming radio voice signals into digital voice signals. It includes a mobile communication module that transmits these digital signals as a series of voice packets over a mobile network. To enhance voice clarity, the system incorporates a signal generator that produces white noise when the voice signal falls below a certain threshold, and a mixer that combines the radio voice signal with this white noise prior to digital conversion.
Additionally, the patent describes a comprehensive radio system that integrates the radio voice terminal, remote device, and the radio network gateway. The receiving and processing module is equipped with a radio voice control module and an audio codec module, which work together to convert the radio voice signal into a digital format. The system also includes a controller module that compresses and converts the digital voice signal into an audio file, enabling voice recognition and content interpretation. This additional information can then be transmitted to the remote device via a streaming server. The remote device may function as a command center, equipped with a gateway server that manages gateway registrations and maintains a list of identification codes for efficient communication.
