This paper introduces the present situation of the maintenance and management of chinese no . 7 signaling net , and expounds the principles and functions of the no . 7 signaling monitoring system and its application in the telecom network 介绍了我国七号信令网的维护管理现状,阐述了七号信令集中监测系统的原理和功能及其在电信网络中的一些具体应用。
This structure makes possible a clear division of responsibility for signalling network management and allows numbering plans of signalling points of the international network and the different national networks to be independent of one another 这种结构能明确地划分信令网管理的责任，允许国际信令网和各种国内信令网的信令点的编号方案相互独立。
With the compositive managements and compositive inspections achieved , the application of this managing system will supervise the signaling network both high efficiently and in real time . the system has high practical value and referential significance 本系统的成功开发，可以实时、高效地监测信令网运行情况，实现了对信令网的集中监测、集中管理，具有重大的实用意义和参考价值。
No . 7 signalling protocol carries all information on telecommunication network and is very valuable information resource . so we can say no . 7 signalling network is the nervous system of telecommunication network and plays a core part in network 七号信令协议承载着通信业务网络运行的所有信息，是非常宝贵的信息资源，因此可以说七号信令网是通信网的神经系统，对通信网络的畅通运行发挥着至关重要的核心作用。
The sgsn communicate with the msc , hlr , sms - giw msc through the signaling network via gs , gr and gd . gc is connected to the hlr and ggsn as an optional interface . the existing elements of the gsm network can support their corresponding interfaces simply by upgrading software Sgsn通过信令网以gs 、 gr 、 gd接口实现与msc 、 hlr 、 sms - giwmsc的通信， gc作为可选接口连接hlr和ggsn ，现有的gsm网元只需进行软件升级就可以支持相应的接口。
Telecommunications management network ( tmn ) is one of the three networks of the telecommunication system which includes the switch network , the signaling network and the tmn . for better connection and better communication , the interfaces of tmn are drawn by itu - u and are executed by the main telecommunication device manufacturers in the globe world 电信管理网( tmn )是电信系统的三大网络系统(交换网、信令网、电信管理网)之一,它的接口标准由国际电信联盟电信标准部( itu - t )制订,全球范围内的主流通信设备制造商遵照执行,其目的是为了实现更好的互连互通。
The second , the thesis illuminateds several kinds of method of signalling affair synthesis on the base of explaining no . 7 signalling system and cdr / tdr ( call detail record / transaction detail record ) . the last , the thesis researchs and analyses the interaction triggering algorithm , a new method of signalling affair synthesis . the basic train of thought , realization method , critical technical element , concrete operation manner and software program is described at length 本论文首先对七号信令网和相应的七号信令监测系统的网路结构进行了探讨和描述，接着在说明了七号信令系统和呼叫详细记录事务详细记录( cdr tdr ? calldetailrecord transactiondetailrecord )的基础上对目前的几种信令事件合成方法进行了分析，然后对一种新的合成算法?交互触发进行了深入的研究和分析，详尽地描述了交互触发的基本思路、实现方法，说明了其创新性的关键技术要点，并给出了具体的实施方式和程序实现。
Build of no . 7 signalling centralized supervision system can effectively obtain signalling information , and analyse the macroscopic and microscopic network realtimely and dynamicly , and accomplish assessment and optimization of network performance . thus , this system provides effective supporting method for management and maintenance of signalling network , and promotes competitive capacity of the enterprise 七号信令集中监测系统的建设，可以有效的获取信令信息，对全网进行实时动态的宏观和微观分析，实现网络性能的评估和优化，从而为信令网的管理和维护以及业务质量的监测和分析提供了有效的支撑手段，提升了网络的竞争力。
The type of node structure realizing multi - granularity optical swithing in ason is put forward and a multi - granularity optical switch using this structure is developed . the software for controlling the node in ason is compiled . the experimental research is carried out with campus network as signalling network and the data network is of mesh architecture , which is a typical architecture in ason 本文提出了一种适用于自动交换光网络的多粒度光交换节点结构，并采用该结构研制出了多粒度光交换机开发了ason的节点控制软件数据网采用ason的典型结构格状网，利用校园网作为信令网进行了实验研究，验证了ason的主要功能。
Due to a & b double flats setting of stp ( signalling transfer point ) in different place , and working on mode of payload - sharing on signalling links ( couple links ) between sp ( signalling point ) and stp , the calling signalling sequence cannot be collected completely from single stp . thus it is difficult to synthesize signalling affair in the signalling supervision system . the first , this thesis illuminateds network architecture of no . 7 signalling network and no . 7 signalling centralized supervision system 由于七号信令网的信令转接点设备stp ( signallingtransferpoint )采用a 、 b双平面异地设置，下一级的信令点设备sp ( signallingpoint )至上一级的一对stp之间的信令路由采用负荷分担方式工作， sp至stp对的负荷分担链路形成耦合链路，导致在一个stp处无法采集到完整的呼叫信令序列，这样就给监测系统核心部分之一的信令事件合成带来了极大的难度。
