Abstract

Embodiments of the present invention provide a terminal access method and device based on NB-IoT. The method includes: obtaining a narrowband Internet of Things NB-IoT deployment area, dividing the NB-IoT deployment area into a plurality of cells according to preset rules; selecting a center point from each cell as a reference node for group clustering of the corresponding cell ; Calculate the distance between each terminal in the NB-IoT deployment area and each reference node, and group according to the distance; connect all terminals in the NB-IoT deployment area to the base station according to the grouping situation. The device is used to execute the method. In the embodiment of the present invention, the NB-IoT deployment area is divided into multiple cells according to preset rules, and the distance between each terminal in the NB-IoT deployment area and the reference node is calculated, according to Group the terminals according to the distance, and then connect the terminals to the base station according to the grouping situation, and group the terminals in the IoT deployment area more reasonably to further improve the access performance of the system.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of the Internet of Things, and in particular to a method and device for scheduling terminal access based on the narrowband Internet of Things. Background technique [0002] Facing the tens of billions of future communication needs of the Internet of Things, traditional communication technologies, such as Bluetooth, 4G, Zigbee, etc., have obvious incompatibility in terms of deployment methods, power consumption, and complexity. Therefore, Low-Power Wide-Area Network (LPWAN) emerged as the times require, and has become one of the main hotspots of today's Internet of Things access technology. Among them, NB-IoT has the characteristics of low cost, low power consumption, wide coverage and large connection, and is the most potential LPWAN technology today. [0003] At the 72nd meeting of the 3GPP RAN Plenary Session, NB-IoT was an important topic of the conference, and its corresponding...
