摘要
在传统物联网定位追踪场景中,使用卫星和运营商公网信号来定位会带来通用性低、功耗大、成本高等局限性。提出将通信模组嵌入物联设备来与基站和定位服务器进行数据连接的方案,利用NB-IoT规范中新增的定位技术对设备进行定位追踪,并在客户端对定位信息进行处理。与现有定位技术相比,该方案能够有效降低物联网接入终端功耗和空口处理复杂度,设备硬件成本也得到了降低。
In the traditional scenario of positioning and tracking for the Internet of Things(IoT), the use of satellite and operator’s public network signal will lead to the limitations of low generality, high power consumption, and high cost. A scheme is proposed in which communication module is embedded in the IoT devices to connect positioning server, the new positioning technique in NB-IoT specifications is used to locate and track devices, and the positioning information is processed in the client. Compared with existing positioning techniques, the proposed scheme can effectively reduce the power consumption of IoT terminals, the processing complexity of air interface, and the hardware cost.
