China Unicom SS7 Moniting System Expansion Designand Realization On International Network

At present, ISDN, PLMN, INN and other business applications in the communication network and improve gradually. As a communication network, one of the three support network, signaling system is the nervous system of the communication network, affecting the entire communications network of the quality and efficiency. NO.7 signaling system is the mainstream of the signaling System, is an advanced international Common Channel Signaling system, has many advantages, widely used internationally. China has basically completed NO.7 signaling network, and formed the Ss7 is the mainly supplemented with the channel-associated signaling, and eventually will replace the CAS with the development of the signaling. While Application and development in the Ss7, for the testing and maintenance to the ss7 sets higher requirement.Currently, all telecom operators in China have established a complete NO.7 signaling network, with the NO.7 network capacity continues to expand, the number of users increase, especially the ss7 in various business applications and the rapid growth of business (such as data, IP telephone and intelligent network, etc.), making the signaling network more complicated. The network conditions of the ss7 directly related to the quality which the operators provide, the maintenance work to NO.7 signaling network directly influence the operator income.China unicom the international bureau ss7 network in centralized monitoring system, the equipment maintenance and trouble, for telephone operation analysis, signaling network management of the work that had played an important role. As the china unicorn international business continuously increased, and users of increasing the number of calls for improving the system of monitoring network scale has been unable to meet the needs of the daily management.China unicorn ss7 monitoring system from the existing monitoring system to solve the problem, try to improve the existing system of the monitoring system and increase the scope of business, the existing system is effective and expansion of business and provide effective means of maintenance and good service quality guarantee.The paper stars with the functional requirenments and network status quo and background,then it details monitoring system design and the new software system functions.The first chapter mainly introduces the china unicom ss7 network the current situation and network status and signal monitoring system for construction and development goals.The second chapter to the basic knowledge of ss7 were introduced, aim at the call detail records definition, generating scheme and realization of process were studied.The third chapter from the use of specific maintenance personnel Angle, puts forward the use of some questions in the new function of system and the demand.The fourth chapter is proposed first overall design principle and design requirements, and then describe how the system software and hardware structure, and then expounds specific equipment expansion plan.The fifth chapter verified.some new system function.The author participate in the completion of the China unicorn ss7 monitoring system design and project implementation work, China unicom ss7 monitoring system to accomplish expansion work, has been put into operation, the system runs in good condition, stable performance, cooperate the kingdom-network management system for China unicom's network security provides a powerful technical support, and the whole system interface intuitive and easy to use, system function, performance, scalability, and maintainability are expected to reach design goal, and gradually in the network operation monitoring, network operation analysis, system maintenance and less likely play an increasingly important role.
