文档介绍：南京邮电大学工程硕士研究生学位论文摘要摘要第三代移动通信(3G)的发展已经从体制标准之争逐步演进到标准的完善和设备开发之争以及未来的产业发展之争。面对激烈的竞争形势,快速提供业务、减少带宽资费、提高通信服务质量成为移动运营商在市场竞争中获胜的关键因素,而这些关键因素之争的焦点又集中在传输网这一基础网络建设上来,因此,3G传输网的建设在整个3G网络发展中扮演着重要的角色。基于传输网络在通信网建设中的重要性,本文着重从3G传输网络规划方面进行了此次毕业设计的论文工作。开始从3G的传输技术、网络标准、传输网的特征等进行技术介绍,其次进行传输网规划设计及核心网组建等方案分析,最后得出结论从而完成整个论文工作。本文在第二章中重点讨论了传输网络的特征和传输网的构建;在第三章中重点讨论了接口及传输网的承载方式还有承载技术的方案选择。在此过程中对承载技术MSTP有了更多的认识。在无线网络的承载方面,MSTP有一定的用武之地,虽然R4版本以后的3G“核心网"将由IP网络承载,但这并不意味传输网络将完全退出对核心网络的支撑,因为至少IP网络的骨干部分仍将由长途波分复用传输系统来承载,而MSTP技术将作为IP城域网的补充得以重要应用。关键词传输技术 MSTP 传输网接口网络规划承载技术南京邮电大学工程硕士研究生学位论文摘要 ABSTRACT The third munication(3G)has evolved from controversy on system standard to controversy of improving standard,equipment development and progress of the petition,providing service with high speed,low cost and high quality。has e the key factors on which mobile ISP can obtain ess in petition based. Furthermore,they a11 focus on the building of infrastructure 。the 3Gtransmi work plays an important role in the overall development of work. For the importance of work work,the thesiS emphasizes on the planning thesiS firstly introduces 3G transmission work standard and features of work. Itsecondly analyzes theplan and design of work and the construction work。and finally reaches the conclusion. The second chapter focuses on thediscussion offeatures of work and itsbuilding:the third chapter mainly introduces the bearer method of interface, andthechoosing of bearer process ofthe paper,I learn more about the bearer technology work’S bearer,MSTP could play a role. Although the work wiII be beard on work after does not mean that work will retreat from supporting pletely, because the backbone of work woul d sti11beard on the long——di stance WDM transporting system,and MSTP technology will beapplied as an plement in IP Metropolitan—work.
