【摘要】：中国电信行业的重组促进了三大运营商之间竞争,对中国电信行业的发展产生了深远的影响。在已经到来的存量竞争时代,运营商高度重视移动互联网市场,希望寻求新的利润增长点。移动互联网对现有计费系统提出了三大挑战,运营流程及协作模式不再具备“属地化部署”的特征;“流量计费”需求凸显,而现有的计费系统只能支持简单的套餐计费等;即时消息、微信等应用呈现上升趋势,全网数据交换从“文件类”数据为主迅速转变为以“消息类”数据为主。中国电信为了应对以上挑战并提升核心竞争力,提出了中国电信计费运营网的概念,以网络化业务支撑能力为目标,兼容现有业务,支持业务网络化全面发展。中国电信计费运营网由业务网元、控制网元和数据网元三种承载不同业务的网元组成,计费网内的所有网元之间采用Diameter基础协议进行数据通信。业务控制系统是指计费网中的控制网元,由业务控制器和业务路由器组成。论文完成了中国电信计费运营网业务控制系统的设计与实现,主要工作包括:计费运营网的介绍和相关技术分析、业务控制系统需求分析、业务控制系统概要设计、业务控制系统详细设计与实现和系统测试等。在业务控制系统需求分析中,以用例图的形式对业务控制系统的需求进行阐述;业务控制系统概要设计从需求出发进行总体设计和基本表结构设计;详细设计与实现阶段针对每个模块的实现流程进行了详细的介绍,具体包括链路管理、路由管理网元管理和拥塞管理等功能实现;最后从单元测试和集成测试两个方面对系统进行了测试,保证系统的正确性。本人在项目中承担了链路管理、路由管理网元管理和拥塞管理的功能设计与实现,并在开发完成之后配合全网组网联合测试。论文完成的计费运营网业务控制系统已经成功通过了组网联合测试,并作为中国电信的业务支撑系统成功上线,后续计费业务将接入中国电信计费运营网。
[Abstract]:The reorganization of China's telecom industry promotes competition among the three major operators and has a profound impact on the development of China's telecommunications industry.In the era of stock competition, operators attach great importance to the mobile Internet market and seek new profit growth points.The mobile Internet poses three major challenges to the existing billing system, such as the operation process and the cooperation mode are no longer characterized by "localized deployment", the demand for "traffic charging" is prominent, while the existing billing system can only support simple package billing, etc.Instant messaging, WeChat and other applications show an upward trend, the whole network data exchange from "file class" data based on the rapid change to "message class" data based.In order to meet the above challenges and enhance the core competitiveness, China Telecom puts forward the concept of China Telecom Billing and operating Network, which aims at supporting network services, compatible with existing services and supporting the overall development of network services.The billing and operation network of China Telecom is composed of three kinds of network elements, namely, service network element, control network element and data network element, which carry different services. All the network elements in the charging network adopt Diameter basic protocol for data communication.The service control system refers to the control network element in the billing network, which consists of the service controller and the service router.The thesis has completed the design and implementation of the service control system of China Telecom Billing and Operation Network. The main work includes the introduction and related technical analysis of the Billing and Operation Network, the requirement analysis of the Service Control system, and the outline design of the Service Control system.Business control system detailed design and implementation and system testing.In the requirement analysis of the business control system, the requirements of the service control system are expounded in the form of use case diagram, the general design of the business control system is designed from the requirements and the basic table structure is designed.The detailed design and implementation of each module are described in detail, including link management, routing management network element management and congestion management.Finally, the system is tested from the aspects of unit test and integration test to ensure the correctness of the system.In the project, I undertake the function design and implementation of link management, routing management element management and congestion management, and cooperate with the whole network joint test after the development.The business control system of the billing and operation network has successfully passed the network joint test and has been successfully launched as the service support system of China Telecom. The subsequent charging service will be connected to the China Telecom charging operation network.
