Call routing and intelligent control are closely linked with the circuit switched network 呼叫路由與智能化控制和電路交換網絡緊密地結合在一起。
However , both the package switched network and the traditional circuit switched network will exist for a long time due to the cost and some technical problems 但是,由于技術和成本問題,傳統電路交換網絡與分組交換網絡還將會在很長時間內并存。
The quick develop of voip technology brought significant contributions to the convinence and speed for communication . therefore , voice communication based on next generation network will replace the circuit switch network 以ip技術為主的分組交換網絡將取代傳統的電路交換網絡,成為將來電信網絡的主體。
The article generalized the interception mode of packed switched network , viop system based on sip and ip network from circuit switched network . the voip system based on sip is distributed system 因此,本文在無線通信系統電路交換域的合法偵聽系統研發的基礎上,將其偵聽模型推廣到包交換域、基于sip的voip系統和ip網絡。
Hi1 port of the packed switched network and that of circuit switched network have the same data structure , also about hi2 port . however , delivery of packetized content of communication ( hi3 port ) shall not use no . 7 signal system but tcp / ip 包交換域和電路交換在hi1和hi2接口上傳輸的數據格式相同,二者hi3接口實現不同,在包交換域中采用tcp ip協議進行傳輸包交換域的偵聽內容。
Ngn has achieved not only the fusion of the network , but , more importantly , fusion of the services through the optimization of the network structure . it enables the package switch network to inherit the abundant service functions which the original circuit switch network has , and quickly provide some new services which can hardly provided by the original network within the whole network at the same time 下一代網絡通過優化網絡結構不但實現了網絡的融合,更重要的是實現了業務的融合,使得分組交換網絡能夠繼承原有電路交換網中豐富的業務功能,同時可以在全網范圍內快速提供原有網絡難以提供的新型業務。
