Abstract

The invention discloses a method and a system for testing consistency of an NAS security mode of an NB-IoT (Narrow Band Internet of Things) terminal. Based on a master computer and a system simulator,an interface of an NAS in an NB-IoT is defined and the NAS security mode of the NB-IoT terminal is tested, so as to perfect existing protocol consistency testing requirements; the method and the system are used in research and development, testing and network authentication work for the NB-IoT, and a commercial terminal passing through authentication can be guaranteed to implement interconnectionand intercommunication with network devices of different manufacturers in an existing network.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method for testing the consistency of a non-access layer security mode of a narrowband Internet of Things terminal. Background technique [0002] Narrow Band Internet of Things (NB-IoT) is one of many low power wide area network (Low Power Wide Access, LPWA) technologies, which can support the cellular data connection of low power consumption devices in the wide area network. NB-IoT has four major characteristics: First, wide coverage, which will provide improved indoor coverage. Under the same frequency band, NB-IoT has a gain of 20dB compared with the existing network, and the coverage area is expanded by 100 times; second, it has the ability to support massive connections. Ability, a sector of NB-IoT can support 100,000 connections, support low latency sensitivity, ultra-low equipment cost, low power consumption and optimized network architecture; the third is lower power consu...
