摘要
随着机器通信(MTC)的快速发展及增长,大量MTC设备同时接入网络会造成无线接入网络的过载问题。为了解决这一问题,3GPP已经在LTE-A网络中提出了一些解决因大量MTC同时涌入而造成的无线网拥塞问题的候选方案。本文通过对这些解决方案进行分析与研究,并在此基础上对融入机器对机器(M2M)业务的LTE-A无线网络侧的随机接入提出优化方案。
As a large number of MTC devices try to access the radio resources in a very short peri- od, the rapid growth in the number of machine - type communications （MTC） devices causes the radio access network （RAN） to overload. Several candidate schemes for RAN improvements for MTC have been under consideration for possible adoption in LTE - A by 3GPP. In the paper, several schemes to control the RAN overload coming from massive number of MTC devices were analyzed , and optimization schemes for furher solution was designed.
