摘 要: 介绍了移动通信网络中随机接入的概念,论述了移动Internet随机接入的特点,提出了基站调控的slotted-ALOHA随机接入方式,并从理论分析和计算机仿真两方面与现行的移动通信随机接入方式进行了对比,表明该方式能显著提高随机接入性能,使用代价微小,易于实际应用。 The conception of random access in mobile telecommunication network and the feature of random access for mobile Internet are introduced, then slotted-ALOHA random access mode controlled by base station is presented. Theoretical analyses and simulation results show that this mode can enormously promote the performance of random access with little cost, and is suitable for application.
