Abstract

The purpose of this work was to assess a real-time testbed scenario using the Software Defined Radio (SDR) technology and the USRP (Universal Software Radio Peripheral) device to provide Voice-over-LTE (VoLTE) call service and grant user internet connectivity in an initial 5G NSA (Non Stand Alone) deployment network. The implemented mobile network considers a 5G mobile network that is composed of both NSA 5G and IMS (IP Multimedia Subsystem) architectures cores. The deployment network considers a soft initial transition from 4G to 5G NSA. In addition, the contribution of this article is to achieve that each element from different architectures is able to communicate to each other and establish the bearer and stream for each IP service. Furthermore, the evaluation of jitter, throughput and RTT delay metrics are presented for a VoLTE call between two devices connected to the deployment SDR 5G NSA network.

SDR 5G NSA移动网络和IMS核心，提供voip LTE业务

这项工作的目的是评估使用软件定义无线电(SDR)技术和USRP(通用软件无线电外设)设备的实时试验台场景，以提供lte语音(VoLTE)呼叫服务，并在初始5G NSA(非独立)部署网络中为用户提供互联网连接。实现的移动网络考虑由NSA 5G和IMS (IP多媒体子系统)架构核心组成的5G移动网络。部署网络考虑从4G向5G NSA软初始过渡。此外，本文的贡献是实现来自不同体系结构的每个元素能够相互通信，并为每个IP服务建立承载和流。此外，对连接到部署SDR 5G NSA网络的两个设备之间的VoLTE呼叫进行了抖动、吞吐量和RTT延迟指标的评估。
