A kind of narrowband internet of things sequence test method and device

Abstract

The embodiment of the present invention discloses a narrowband Internet of Things sequence test method and device. The method includes: combining test cases of transmission signals of various parameters of the narrowband Internet of Things to obtain at least one test sequence; generating a device under test according to at least one test sequence The sequence parameters to be tested and the configuration sequence parameters of the tester; the control tester transmits a preset waveform signal to the device under test according to the configuration sequence parameters, so that after the device under test receives the preset waveform signal, The at least one test sequence is sequentially executed for testing. By merging several test cases of NB-IoT to generate a test sequence, the number of communications is reduced, the verification test speed of NB-IoT is greatly improved, and the production efficiency is improved; at the same time, by generating the sequence parameters of the device under test and the tester The configuration sequence parameters can quantitatively complete the data collection and analysis of the specified data volume of NB-IoT, reducing the uncertainty.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a narrowband Internet of Things sequence test method and device. Background technique [0002] The Internet of Things (IOT) is committed to the interconnection of all things, and the massive connections of Narrow Band Internet of Things (NB-IoT) applications mean the production demand of massive modules. It is necessary to reduce the production time of unit modules to improve Productivity. The lower module cost of NB-IOT means that the production cost must match the module cost, and the production cost of the unit module needs to be reduced accordingly. [0003] Cellular-based NB-IoT has become an important branch of the Internet of Everything. NB-IoT is built on cellular networks and only consumes about 180KHz of bandwidth. It can be directly deployed on GSM networks, UMTS networks or LTE networks to reduce deployment costs and achieve smo...

Problems solved by technology

[0035] 3) The signal acquisition and processing in each test case is carried out on continuous signals, and uncertainty will be introduced in the case of unstable signals;

[0036] 4) There is a correlation between the generation of the transmission signal of the DUT in each case and the cell content of the test instrument (system simulator), which may cause inconsistencies in the transmission signals generated under different test instruments

[0038] 1) Since the test environment is still established one by one, it means that all test cases can only be executed one by one in a specific environment;

[0039] 2) The signal acquisition and processing in each test case is carried out on continuous signals, and uncertainty will be introduced in the case of unstable signals
