Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of communications, and more particularly to a real-time voice relay apparatus and method based on a public network. BACKGROUND OF THE INVENTION Voice broadcast is a method of providing voice broadcasts to a plurality of users through a specific relay device such as a conventional radio or television. The traditional voice broadcast implementation principle is to collect voice content on a radio or television station, and frequency-modulate the voice data, and then transmit the frequency-modulated voice content through a radio transmitting device, and the user listens through the radio or the television terminal. For example, live broadcasts such as concerts, football matches, and basketball games are based on this traditional application. This application is characterized by the need for a complete set of relay equipment. However, these kits are relatively expensive. In addition, users need a radio or TV terminal to listen to. If they don't have a radio or TV at hand, they can't listen to wonderful real-time voice programs, such as football broadcasts. Moreover, this kind of broadcast is easy to be affected by terrain or terrain. The restrictions, such as in the mountains, cannot be heard by voice broadcasts because the radio waves are blocked by the terrain. Therefore, a solution is proposed in the prior art, and Patent Document 1 (CN 1845536A) discloses a method and system for real-time voice transmission based on Ethernet, which system is composed of several network voice devices, each network voice The devices are connected by Ethernet and TCP/IP network. Among them, Ethernet is only used to transmit real-time voice data packets, and TCP/IP network is used to transmit request control information between devices. Moreover, in the method for real-time voice transmission based on Ethernet, the voice data stream collected by the voice module is converted into an Ethernet data packet by the main control unit in the network voice device, and directly transmitted to the called network voice device through the Ethernet. The main control unit in the called network voice device unpacks the received voice data packet in the form of an Ethernet data packet, extracts the voice data stream therein, and transmits it to the voice module connected thereto through the data bus, and the voice module Play it out. The above solution requires the application of Ethernet to relay voice. However, Ethernet has a limited distribution range and limited audience, which greatly limits its application. With the rapid development of network technology, network bandwidth has increased by orders of magnitude, currently based on fiber-optic transmission. The transmission network transmission rate has reached lG bps, even 10G bps, and the broadband network has become more popular and popularized into the home.

On average, one in three people owns one. Mobile phones; on average, every two households is a landline (estimated by 3 people per family). As the number of users increases, the telephone charges become cheaper and cheaper. Therefore, it is possible to use voice broadcasts in data networks and telephone networks, such as listening to real-time broadcast programs on the Internet and listening to real-time voice broadcast programs by telephone (fixed telephone and mobile phone). It is completely possible to listen to real-time broadcasts with a phone call, and you can listen to real-time broadcasts when you have a network.
