【摘要】 经过近几年移动公司传输网络的大规模建设，骨干网、城域网均已初具规模。随着DWDM和10Gbit／sSDH在骨干传送网上的大量应用，系统容量问题已经得到了较好地解决，同时考虑到3G即将开始建设，为3G接入的配套传输建设应提前进行，因此，目前的建设重点便放在了城域传送网上。目前的城域网，传送的主要还是基站和专线接入等语音业务，但以CMNET／GPRS VPN接入为代表的数据业务增长迅速，与传统的语音业务相比，数据业务的流量、流向更为复杂，对带宽、安全性的要求也多种多样。NGN网络正在快速发展，支持数据业务的第三代移动通信即将推出，这些均要求城域传输网络应该是一个通用的传输平台，能高效可靠地传输各种业务。这就需要城域传输网产品在保证对语音业务支持的同时，支持多种数据接口，优化数据传输效率。近几年移动业务对固话业务的替代日益明显，移动业务仍处于快速发展期，网络日益庞大，对城域传送网的容量需求越来越大。因此济南移动城域光传送网规划建设立足于语音业务为移动公司主要收入来源且仍在快速增长这一现状，兼顾同时也在快速发展的数据业务，合理选择组网方案，建设符合移动运营商业务发展的城域光传送网。本课题首先论述了城域网的概念、结构及几种组网的技术，对SDH、波分技术、MSTP技术进行了介绍，通过分析城域网承载的业务类型引出了济南移动各业务网(语音、数据及集团客户接入)的发展规划及对城域网提供传输通路的需求。探讨了城域网建设时的组网结构及原则，根据济南城域网现状并结合业务发展预测了传输通路的需求，确定了济南移动06年城域光传送网的建设方案(网络结构及规模)。建设方案已部分实施，对公司各项业务(语音、数据)的快速发展起到了有力的支撑，达到了指导网络建设的目的和效果。本论文同时对完成建设的系统的调测结果进行了总结。更多还原

【Abstract】 Through the trasportation network large scale builds of the mobile company over the past few years, backbone network, MAN begin to take shape already. Upper great quantity applies of DWDM and 10 Gbit/sSDH in backbone network, problem of system capacity has already got fairly good solved. Think that the 3G starts construction soon at the same time, it should shift to an earlier date being in progress of the supporting trasportation construction for 3G.Therefore, the build priority is MAN.At present MAN transfer main part voice business such as base stand and line for special use cut-over, the data business such as CMNET/GPRS VPN cut-over as representative increase prompt, compared with the traditional voice service , data business rate of flow, flow direction are more complicated, the request to bandwidth, security is also varied. NGN network is under rapid development, and 3G mobile communication supporting data transaction will be introduced very soon, all of which require MAN should be a uniform platform, and it can transfer vairous transaction enficiently and in secure. Thus it is demanded that MAN product can support multiple data interface, and enhance transferring enficiency, while guaranteeing voice service supportable.These years the replacement of fixed phone with mobile phone is becoming more and more obvious, and mobile servie still in rocketing, its network is getting huger, and it requires bigger and bigger capacity of MAN. Therefore, JinanMobile MAN optical transfering networking is establishing their networking based on the fact that voice service is the main profit source of mobile bissiness, as well as considering the rapidly developing data transaction, choosing apropriate net solutions, and establishing MAN optical transportation network suitable for mobile business development.The paper has discussed the concept of MAN, structure and several kinds group net technology first, introduced the technology of SDH、 WDM、 MSTP. By analysing the business type of the MAN, it introduced the development plans of JinanMobile’s every business net (voice, data and customer of Corp. cut-over) and provides the need of transferring passage to MAN. It also discussed the group net structure and principle of MAN under construction. Based on JinanMobile’s current situation of MAN and business development the paper forecast the need of transferring passage, having ascertained JinanMobile’s MAN Optical Transportation Network construction scheme for 2006 (network structure and scale). The construction scheme have already part be put into effect. It brought the important effect on the fleetness develops of various company business (voice, data) and have reached purpose and effect of guiding network construction. The paper also having carried out a summary of the accomplishing construction’s tune measures result.更多还原
