基于开源协议栈的VOLTE通信平台的研究和实现

Research and Implementation of the VOLTE Communication Platform Based on Open-Sourcing

介绍基于软件无线电(Software Defined Radio,SDR)实现的模拟基站、基于开放接口(Open Air Interface,OAI)实现的LTE开源无线通信系统以及基于开放IP多媒体子系统(Open IP Multimedia Subsystem,Open IMS)实现的IMS架构的通信系统核心网。重点分析各开源系统的软硬件平台和连接流程,通过搭建OAI eNB+OAI EPC+LTE商用手机的实验架构,实现LTE手机的语音、短信以及数据业务的互通,旨在为科研人员提供一个符合真实场景的实验平台。

At first,this paper introduces the OpenAirInterface,which implements LTE wireless communication system of open-sourcing based on the SDR.And then this paper introduces the Open IMS,which implements IMS core communication system.It mainly analyzes the software and hardware platform of OAI and Open IMS.By building the experiment framework of OAI eNB+OAI EPC+LTE commercial mobile phone,the voice,message and data services of LTE mobile phone can be exchanged,can be provide a real environment to the LTE researchers.
