Call routing and intelligent control are closely linked with the circuit switched network 呼叫路由与智能化控制和电路交换网络紧密地结合在一起。
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,由于技术和成本问题,传统电路交换网络与分组交换网络还将会在很长时间内并存。
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技术为主的分组交换网络将取代传统的电路交换网络,成为将来电信网络的主体。
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,本文在无线通信系统电路交换域的合法侦听系统研发的基础上,将其侦听模型推广到包交换域、基于sip的voip系统和ip网络。
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 包交换域和电路交换在hi1和hi2接口上传输的数据格式相同,二者hi3接口实现不同,在包交换域中采用tcp ip协议进行传输包交换域的侦听内容。
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 下一代网络通过优化网络结构不但实现了网络的融合,更重要的是实现了业务的融合,使得分组交换网络能够继承原有电路交换网中丰富的业务功能,同时可以在全网范围内快速提供原有网络难以提供的新型业务。
