| 摘 要： | 首先简要介绍了3GPP中基于LTE的物联网体系结构，进而分析了物联网中存在的过载问题，然后重点研究了接入类别限制ACB（Access Class Barring）与扩展访问限制EAB（Extended Access Barring），最后针对这两种机制的不足，提出了改进限制方案IBS（Improved Barring Scheme）机制，该机制通过接收端向发送端发送错误重传请求允许，来避免过载情况中数据频繁重发的问题。

| Abstract: | This paper first describes the architecture of M2M based on LTE technology in 3GPP,and discusses the network overload problems in loT. Then this paper focuses on ACB（ Access Class Barring） and ECB （Extended Access Barring）. And finally, aiming at the remedy of these two shortages, IBS （Improved Barring Scheme） is proposed. This mechanism may avoid frequent data-retransmission problem in overload situation by sending error retransmission request permission packets from the receiver to the sender. |
