背景技术Background technique
随着智能城市、大数据时代的来临，无线通信将实现万物连接。很多企业预计未来全球物联网连接数将是千亿级的时代。目前已经出现了大量物与物的联接， 然而这些联接大多通过蓝牙、Wi-Fi等短距通信技术承载，无法实现长距离通讯。我们正进入万物互联(IoT)的时代，这对于整个移动通信产业来说是一个巨大的机会。这一点在MWC2016上展露无疑。无论是运营商大咖，还是设备商巨头，纷纷展示了完整的物联网解决方案和在不同垂直行业的应用。With the advent of smart cities and the era of big data, wireless communication will realize the connection of everything. Many companies predict that the number of global IoT connections will be hundreds of billions in the future. At present, there have been a large number of connections between things. However, most of these connections are carried by short-distance communication technologies such as Bluetooth and Wi-Fi, and long-distance communication cannot be realized. We are entering the era of the Internet of Everything (IoT), which is a huge opportunity for the entire mobile communication industry. This point was undoubtedly revealed at MWC2016. Whether it is a major operator or a giant equipment manufacturer, they have demonstrated complete IoT solutions and applications in different vertical industries.
当然，实现这一切的基础，是要有无处不在的网络联接。运营商的网络是全球覆盖最为广泛的网络，因此在接入能力上有独特的优势。然而，一个不容忽视的现实情况是，真正承载到移动网络上的物与物联接只占到联接总数的10%，大部分的物与物联接通过蓝牙、WiFi等技术来承载。终端功耗过高，且传统技术无法满足海量终端的应用需求，现有场景下也存在网络覆盖不足的问题。当前传统物联网技术也存在终端种类多、批量小、业务开发门槛高、综合成本的一些不可忽视的问题。为此，我们选择低功耗NB-IoT通信技术，NB-IOT的优势在于技术方面的长距离能力及相比传统网络下的低带宽消耗、模块芯片的超低成本及网络的超强覆盖。Of course, the basis for realizing all this is to have ubiquitous network connections. The operator's network has the most extensive coverage in the world, so it has unique advantages in access capabilities. However, a reality that cannot be ignored is that the connection between things that are actually carried on the mobile network accounts for only 10% of the total connections, and most of the connections between things are carried by technologies such as Bluetooth and WiFi. The power consumption of terminals is too high, and traditional technologies cannot meet the application requirements of a large number of terminals. There is also a problem of insufficient network coverage in existing scenarios. At present, the traditional Internet of Things technology also has some problems that cannot be ignored, such as many types of terminals, small batches, high business development thresholds, and comprehensive costs. To this end, we choose low-power NB-IoT communication technology. The advantages of NB-IOT lie in its long-distance technical capabilities, low bandwidth consumption compared to traditional networks, ultra-low cost of module chips, and super coverage of the network.
经对现有技术的文献检索发现，在低功耗NB-IOT技术方面还有很大欠缺。After searching the literature of the prior art, it is found that there is still a big gap in the low-power NB-IOT technology.
