【摘要】：随着移动互联网市场的快速发展,人们对移动通信网络的安全性和带宽提出了更高的需求。分组传送网(PTN)技术具备传统SDH安全性与IP网络高带宽的双重优势,是一种高效、灵活的大容量信息传送和承载平台,已成为当前传送网的主要发展方向。通过对PTN技术进行介绍和分析,同时结合连云港地区现状,本文将PTN技术成功应用于连云港移动4G传送网系统的规划和设计等过程。首先,介绍了PTN的基本原理、关键技术和系统架构。对PTN的保护技术、同步技术、电信级的OAM技术及Qos技术等技术进行了重点介绍,并详细分析了PTN各层结构及功能以及标准的框架结构和关系。其次,提出了面向LTE的城域传送网的网络规划。介绍了PTN的网络规划流程、部署策略、业务需求、组网模式,给出了移动4G PTN城域网整体规划方案。最后,针对连云港城域网的实际情况和4G业务的需求,提出了连云港4G配套传送承载网网络架构,给出了详细的PTN L3层核心层网络建设方案、PTN L2层汇聚层整体规划及组网方案和各区域PTN接入层详细的组环结构,最终在工程建设中成功实现连云港全网4G基站的PTN技术承载。
[Abstract]:With the rapid development of the mobile Internet market, the security and bandwidth of the mobile communication network have been put forward a higher demand. Packet Transport Network (SDH) technology has the dual advantages of traditional SDH security and high bandwidth of IP network. It is an efficient and flexible platform for large capacity information transmission and carrying. It has become the main developing direction of the current transport network. Through the introduction and analysis of PTN technology and the current situation of Lianyungang area, this paper successfully applies PTN technology to the planning and design of Lianyungang mobile 4G transport network system. Firstly, the basic principle, key technology and system architecture of PTN are introduced. In this paper, the protection technology, synchronization technology, OAM technology and Qos technology of PTN are introduced in detail, and the structure and function of each layer of PTN are analyzed in detail as well as the frame structure and relation of standard. Secondly, the LTE-oriented metropolitan area transport network planning is proposed. This paper introduces the network planning process, deployment strategy, service requirement and networking mode of PTN, and gives the overall planning scheme of mobile 4G PTN metropolitan area network. Finally, according to the actual situation of Lianyungang metropolitan area network and the demand of 4G service, the paper puts forward the supporting transport carrying network architecture of 4G in Lianyungang. In this paper, a detailed PTN L3 core layer network construction scheme is presented. The overall planning and networking scheme of PTN L2 convergent layer and the detailed ring formation structure of PTN access layer in each region are given. Finally, the PTN technology carrying capacity of 4G base station in Lianyungang network is successfully realized in the construction of the project.
