Abstract

The present invention provides a narrowband Internet of Things NB-IOT cell reselection method and drive test equipment, the drive test equipment includes: a frequency sweep module and a terminal module, the method includes: obtaining the signal strength of the first cell and the second cell Signal strength, where the signal strength of the first cell is measured by the frequency scanning module, and the signal strength of the second cell is measured by the terminal module; when the signal strength of the first cell and the signal strength of the second cell meet the preset conditions, Execute the cell search procedure. When cell reselection is required, the present invention can realize cell reselection through the cell search process, can speed up cell reselection speed, and improve cell reselection efficiency, thus avoiding the problem of low evaluation accuracy caused by reselection lag, Thereby improving the accuracy of NB-IOT system wireless network optimization evaluation.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and more particularly to a narrow band net-IoT resultive method and a road testing device. Background technique [0002] In the Narrow Band Internet of Things, NB-IOT) communication system, the NB-IOT test device can be used for road testing when the NB-IOT is overwritten. At the time of the road test, the road test equipment will inevitably perform cell reselection processes. Since the idle measurement in the cell reselection requires parsing system messages, in the NB-IoT system, the system message, Si) transmission period and transmission length are longer, the maximum cycle is 40.96s, the maximum window is 16S This will result in a long time, generally reach more than 10s, and the vehicle speed is 36km / h, and the car has been driven during the process. It causes the road test equipment to be retarded, and the road test equipment may have Arriving at the edge of the service cell,...
