摘　　要：窄带物联网(NB-IoT)技术标准已经成熟,文章针对基于长期演进(LTE)核心网的NB-IoT建网方式,提出了一种审计方案。说明了NB-IoT在核心网中的数据传输方式与组网架构,分析核心网中的三种接口的数据,模拟测试审计方案中通过S1-MME和S11两种不同核心网接口进行终端会话管理的性能。现场结果表明,该审计方法能分析出公共陆地移动网络(PLMN)中的物联网应用数据以及终端信息,模拟性能测试则表明通过LTE理性能更佳。The technical standard of the narrow band Internet of things(NB-IoT)has been mature. In term evolution(LTE)core network. The data transmission mode and network architecture of NB-IoT in the core network are explained,and the data of three kinds of interfaces in the core network are analyzed.The performance of terminal session management through the two different core network interfaces of S1-MME and S11 is simulated in the simulation test audit scheme. The field results show that the audit method can analyze the application data and terminal information of the Internet of things in the public land mobile network(PLMN),and the simulation performance test shows that the performance of the NB-IoT terminal session management is better through the S11 interface of the LTE core network.
