基于开源项目的GPRS系统的设计研究

Research on the Design of GPRS System Based on Open Source Projects

设计了一个基于开源项目GPRS系统。主要是基于升级的OpenBTS项目,并且引入OpenBSC和OpenGGSN的项目来处理分组业务。对现有OpenBTS系统进行了软件升级,包括实现具有全功能的软件PCU,重新配置通道资源,添加或修改必要的控制消息等。本工作有助于OpenBTS项目的开发和其应用程序的扩展。

A GPRS system based on several open source projects is designed in this paper. The traditional GPRS sys-tem is an upgrade to the GSM network, while our GPRS system is mainly based on an upgraded OpenBTS project. Mean-time, projects of OpenBSC and OpenGGSN are introduced to handle packet traffic. In this paper, a software-only upgrade tothe existing OpenBTS system is made, including implementing a software PCU with full function, reconfiguring channel re-sources, adding or modifying necessary control messages, etc. The work conducted in this paper is helpful to the develop-ment of OpenBTS project and expansion of its applications.
