Abstract

Embodiments of the invention provide a terminal access scheduling method and device based on NB-IoT (Narrow Band-Internet of Things). The method comprises the steps of: acquiring an NB-IoT deploymentarea, dividing the NB-IoT deployment area into a plurality of cells according to a predetermined rule; selecting one central point from each cell to serve as a reference node for group clustering of the corresponding cells; calculating the distance between each terminal in the NB-IoT deployment area and the each reference node, performing grouping according to the distance; and enabling the all terminals in the NB-IoT deployment area to access a base station according to the grouping situation. The device is used for executing the method. According to the method of the invention, the NB-IoT deployment area is divided into the plurality of cells according to the predetermined rule, the distance between the each terminal in the NB-IoT deployment area and the each reference node is calculated, after that, grouping is performed according to the distance, then the terminals are enabled to access the base station according to the grouping situation, therefore, the terminals in the IoT deployment area can be grouped reasonably, and access performance of a system can be further improved.

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...
