Abstract

The invention discloses a system and a method for testing the non-access stratum authentication function conformance of a narrow-band Internet-of-things (NB-IoT) terminal. Based on a master computer and a system simulator, the interface of a non-access stratum NAS in an NB-IoT is defined, and the NAS authentication function of an NB-IoT terminal is tested, in order to improve the existing protocolconformance test requirements. The system and the method can also be used in the research and development, test and network access certification work for NB-IoT in the future. It is ensured that an authenticated commercial terminal can be connected with network equipment from different manufacturers in the existing network.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for testing the consistency of authentication function of a non-access layer 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 po...
