摘要
这项工作提出了一个测试平台，用于模拟初始5G NSA(非独立)网络，以提供VoLTE (Voice over LTE)呼叫。配置测试平台依赖于使用开源项目以及使用IMS (IP多媒体子系统)网络的SIP(会话发起协议)进行实时通信和信令消息的Kamailio服务器。此外，使用Open5GS开源项目实现4G EPC (Evolved Packet Core)和5G网络功能，这些功能是使用C语言软件开发的。由SDR(软件定义无线电)设备即USRP(通用软件无线电外设)组成的BTS(基站收发器)完成了试验台的设置。给出了抖动值和吞吐量值。这项工作的贡献是提供了一个相对低成本的替代VoLTE测试平台，以及大学教学和研究的实验环境的可用性。
A testbed and methodology for initial 5G NSA mobile deployment to provide voice services over IMS using SDR
—This work presents a testbed for simulating an initial 5G NSA (Non Standalone) network to provide VoLTE (Voice over LTE) calls. The configuration testbed relies on using open-source projects as well as the Kamailio server for real-time communication and signaling messages using the SIP (Session Initiation Protocol) of the IMS (IP Multimedia Subsystem) network. In addition, the Open5GS open source project is used to implement a 4G EPC (Evolved Packet Core) and 5G network functions that were developed using a C language software. A BTS (Base Transceiver Station), composed of a SDR (Software Defined Radio) equipment i.e. USRP (Universal Software Radio Peripheral) complete the testbed setup. The jitter and throughput values are also presented. The contribution of this work is to present a relatively low-cost alternative VoLTE testbed, as well as the availability of an experimental environment for teaching and research within universities.
