摘　　要：本文着眼于移动通信IP化的发展趋势 ,尤其是未来移动Internet随机接入的特点 ,提出了双发随机接入方式 ,导出了该方式接入成功率和信道负载间的关系式。理论分析和实验结果表明 ,这种方式适用于移动网络中的轻载小区 ,能节省无线频率资源 。In accordance with the trend of mobile telecommunication in IP , especially the feature of random access for mobile Internet in future, this paper raised the double send random access mode, and introduced the relation of access success radio and channel load in this mode. Theory analyses and test results showed that this mode was suitable to light load cells in mobile networks, could save enormous wireless frequency resources, and could promote the resistibility against channel degradation greatly.
