Classified Index: TN916.2 U.D.C.: 629.78 Dissertation for the Master’s Degree in Engineering THE ANALYSIS AND PROJECT DESIGN OF THE TRUNK NETWORKING IN HARBIN TELEPHONE NETWORK INTELLECTUALIZATION Candidate： Cui Yulin Supervisor： Associate Prof. Liu Ningqing Academic Degree Applied for: Master of Engineering Specialty： Electronic and Communication Engineering Affiliation: China Netcom Group Harbin Branch Date of Oral Examination： July, 2007 University： Harbin Institute of Technology 哈尔滨工业大学工程硕士学位论文 哈尔滨工业大学工程硕士学位论文 - - I - 摘要 随着通信市场竞争的日益加剧，使哈尔滨网通公司这样的传统运营商的固 定网络存在的种种弊端显得越发突出，严重阻碍了业务的发展、收入的进一步 提高。本课题所探讨的固网智能化的目的就是要改变目前哈尔滨网通公司的这 种颓势局面。 本文介绍了固网智能化的基本思想、关键技术，在对哈尔滨网通公司现有 网络的深入研究基础上，提出了哈尔滨智能网建设的发展思路，系统研究了引 入软交换汇接局和用户集中数据库对哈尔滨网通公司固网智能化改造的影响， 设计了了利用中继网关与现有 PSTN 网之间实现中继组网的方案，完成了对哈 尔滨固网网络智能化的组网方案。 固网智能化可以有效地满足哈尔滨网通对网络建设、演进、业务开拓等多 方面的需求，既弥补现有 PSTN 业务提供能力的不足，也符合长期 PSTN 向 NGN、3G 演进的要求。哈尔滨网通公司固网智能化对哈尔滨网通的发展将有 重大意义。 关键词 固网智能化；软交换；用户集中数据库；下一代网络 - - II - Abstract With the competition in correspondence becoming more and more fierce, the telephone phone of the traditional telecommunication operator like Harbin network telecommunication company has some disadvantage which severely block the service’s development and income promotion. The first thing this paper should consider is to change the declining situation. The text introduced the telephone network intellectualization to turn respectively of basic thought, the technical core, proposed the evolution direction for the intellectualized network construction based on a further research about Harbin network Correspondence company’s network, and investigated the influence of intellectualization of the telephone network by soft switch and concentrating user database systemically. Finally the text designed technique projects which use trunk gateway connecting the present PSTN network, finished project of Harbin telephone network intellectualization. Telephone network intellectualization can satisfy the need of the network construction, evo
