dc.description.abstract電信網路最主要的目的是提供用戶交換接續的功能,而其中是要靠各種不 同的信號方式來建立、釋放通話路由,並且進行計費。由於第七號共通道 信號方式(SS7) 所具有的種種優點已成為信號方式的標準且為未來信號方 式的主流。話務品管的工作是要使電信網路在最經濟的情況下提供最佳的 服務,因此實際查測、評估網路話務負荷是必要的。而話務負荷評估模式 參數值的訂定關係到交換機網路設備的規劃設置,更進而影響整個電信局 的人員、機房、設備等等各種營運成本。因此,對參數值的選擇非常重要 。本研究是藉由研討信號網路系統和話務觀念,並且以實證研究方式利用 統計迴歸方法,針對台灣長途電信網路,實際查測分析SS7 信號信息和通 話路話務。首先,對SS7 信號鏈路做一負荷上的驗證,了解以目前的SS7 架構,信號數據鏈路負荷在未來將傳統信號方式全部改為SS7 信號方式時 ,尚能承擔整個公眾電話網路(PSTN)的信號傳送任務。其次,對各種通話 路由話務負荷做一理論和實證上的驗證,同時找出最佳的話務負荷評估模 式參數值,而其結果對整體的影響是在高效路由方面減少電路設備約5%, 在終接路由方面減少約2%。最後,實際設計建構一套具有實用性包括預測 系統和負荷監視警示系統的話務管理工具,以做為本研究更具體的貢獻。 The main purpose of the telecommunications network is to provide customers the switching and connection functions. It depends on different signaling systems to setup, release speech routes, and to charge.Signaling system NO.7(SS7) which posesses various kinds of advantages has become the standard and mainstream of signaling systems. The task of traffic quality control is to get telecommuni- cations network provides the best service in the most economic situation. So,to make physically measurement,assessment of traffic loading of network is necessary. Nevertheless, the parameter value of the traffic loading assessment model is related to the facilities of switching network, and affects the administration costs about personnels, machine rooms, equipments, etc. Therefore, it is very important to select the parameter value. This study is by way of discussing signaling system and traffic concepts, furthermore, using empirical study and statistical regression methodologies to measure and analyze both signaling messages of SS7 and speech route traffic of toll telecommunications in Taiwan. Firstly, verify the loading of SS7 signaling link. While the traditional signaling system is changed to SS7 in the future, thesignaling link can still bear the signaling trans- mission task of Public Switching Telephone Network(PSTN) under current SS7 architecture. Secondary, verify traffic loading of various kinds of routes theorotically and empirically. Additionally find the optimal parameter values of traffic loading assessment models. In consequence, the whole affections are decreasing circuit facilities about 5% in high route ,and decreasing circuit facilities about 2% in final route. Finally, design and implement physically a useful traffic management tool,including forcasting system and loading monitor alarm system, as more concrete contribution for the study.zh_TW
