摘　　要：3G网络以其良好的移动性和高速数据率传输特性得到了广泛的应用,通过3G网络平台可以实现便捷的广播直播。针对现有的3G网络广播直播中出现的不能够在实时性、高清和稳定性几个主要方面兼顾的问题,提出了使用FEC技术、热备份和PID控制等关键技术相结合的3G实时音频传输方法。经过实际测试验证发现,该方法可以大大提高3G网络广播直播系统的稳健性。这项技术最终在实际电台上得到了运用,并取得了很好的效果。3G network has been widely applied because of its good mobility and high data transmission characteristics. The live broadcasting could be realized conveniently with the help of 3G network platform. Present 3G network live broadcasting is hard to take into account all-round live streaming. This paper discussed a 3G real-time transmission method with FED, hot backup and PID technologies. This method has been tested and proved to improve the soundness when live broadcasting.
