摘　　要：随着机器型通信(MTC)设备的广泛部署和使用,MTC已经和移动通信网络紧密结合,MTC设备数目的大量增加使得对于通信系统各项技术的要求也变得更为严格。分析了MTC的特点及国内外发展趋势,讨论了LTE-Advanced网络MTC的接入网过载控制、资源分配、节能方案的技术问题,介绍了LTE-Advanced网络MTC的典型优化方法,针对MTC在R12及以后版本中的可扩展性问题及其发展目标提出了技术改进方案。With the widespread deployment and use of MTC （machine-type communication） devices, MTC has been closely integrated with the mobile communication network. Significant increase in the number of MTC devices causes more strict requirements for communication system. According to the characteristics of MTC communication and the development trend, three key areas of MTC in current LTE-Advanced network were discussed： RAN overload control, efficient radio resource allocation and energy savings. Several research challenges that need to be addressed for scalable support of MTC devices for R12 and beyond were summarized, typical optimization methods and solutions were introduced, and corresponding improvement directions according to the current application status were put forward.
