Summary: | 碩士 === 國立交通大學 === 資訊管理研究所 === 83 === 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.
