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(wǎng)絡(luò)緊密地結(jié)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(shù)和成本問題,傳統(tǒng)電路交換網(wǎng)絡(luò)與分組交換網(wǎng)絡(luò)還將會(huì)在很長(zhǎng)時(shí)間內(nèi)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(shù)為主的分組交換網(wǎng)絡(luò)將取代傳統(tǒng)的電路交換網(wǎng)絡(luò),成為將來(lái)電信網(wǎng)絡(luò)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(wú)線通信系統(tǒng)電路交換域的合法偵聽系統(tǒng)研發(fā)的基礎(chǔ)上,將其偵聽模型推廣到包交換域、基于sip的voip系統(tǒng)和ip網(wǎng)絡(luò)。
