Machine-to-machine communications in 4G networks

该提案的目的是为当前和未来的机器对机器（M2M）通信网络研究和开发新的和改进的解决方案和技术。M2M是指不需要人的监督或交互的智能电子设备之间的数据通信;这种网络可以在智能电力/智能电网、电子健康、安全和安保以及城市自动化等不同的应用领域中找到，并且在不久的将来，支持MTC的设备的数量预计将达到数亿。MTC提出了现有技术无法充分支持的许多挑战。我们以双管齐下的方式应对这些挑战。首先，我们提出了改进第三代合作伙伴计划的长期演进（3GPP LTE）架构，最值得注意的是，新的子系统（M2M促进器和M2M用户服务器）专门面向支持M2M流量。其次，我们描述了LTE无线电接入的改进，这将允许M2M流量通过基于FDM或TDM的接入与传统蜂窝客户共享频谱。最后，我们描述了M2M通信网络的可扩展安全解决方案。在所有这些领域中，我们假设M2M终端直接连接到LTE蜂窝网络。拟议的研究将使LTE网络具有改进的能力，以有效和可靠的方式支持M2M流量，从而促进先进的M2M网络的开发和部署。

The aim of this proposal is research and development of new and improved solutions and technologies for current and future Machine-to-Machine (M2M) communication networks. M2M denotes data communication between smart electronic devices that do not need human supervision or interaction; such networks can be found in such diverse application areas as smart power/smart grid, electronic health, safety and security, and city automation, and the number of MTC-enabled devices is expected to reach hundreds of millions in the near future. MTC poses a number of challenges that existing technology is unable to adequately support. We address these challenges in a two-pronged approach. First, we propose improvements in 3rd Generation Partnership Project's Long Term Evolution (3GPP LTE) architecture, most notably, novel subsystems (M2M Facilitator and M2M Subscriber Server) specifically geared to support M2M traffic. Second, we describe improvements in LTE radio access that will allow M2M traffic to share spectrum with traditional cellular customers through FDM- or TDM-based access. Finally, we describe scalable security solutions for M2M communication networks. In all of these areas, we assume that M2M terminals are directly connected to a LTE cellular network. Proposed research will equip LTE networks with improved capability to support M2M traffic in an efficient and reliable manner, and thus facilitate the development and deployment of advanced M2M networks.
