摘要
研究表明,M2M通信具有潜在的市场前景,海量终端接入使得移动网络面临着网络拥塞的问题。本文首先分析了移动网络拥塞产生的场景,在此基础上按照核心网络、终端和无线网络分别描述了不同层面的解决方案。其中核心网络的解决方案包括拥塞识别、接入拒绝方法;终端设置低优先级说明了低优先级是与应用相关的;无线网络的解决方案包括拥塞控制触发机制、接入控制参数以及接入控制的实现方式;最后分析了三个层面解决方案的优缺点,并对一些新的方案进行了简要的分析。
At present,Machine-to-Machine（M2M） communication have become new services with large market potential.Mass devices accessing brings the congestion problems to the mobile network.Firstly,the article analyzed the use cases of moble network overload.Three kinds of solutions are described following the use cases.One of these is core network solution,includes congestion detection,rejecting methords.The other one is low priority indication provided in M2M devices,and the indication is related to the application.The third one is wireless network solution,includes congestion control trigger method,access control mechanism.At the end of the paper,the advantages and disadvantages of the paper are analyzed,while some new solutions are also analyzed briefly.
