第5题:
【Recently, telecommunication carriers has been building All-IP core networks in order to effectively support various kinds of fixed and mobile broadband services,such as up-and down-loading You tube and SNS(Social Networking Services)with rich video file,as well as broadband mobile Internet services. Such All-IP network is called NGN(Next Generation Network),which guarantees secure authentication and QoS such as the bandwidth and the delay. From the service point of view,convergence of fixed and mobile communications,known as FMC(Fixed Mobile Convergence)is becoming a key increasing new services and expanding the market.】 Form the paragraph above,we can see that()can be defined as a network that can effectively support various kinds of fixed and mobile broadband services,with guaranteed QoS in terms of()and etc. And the key to develop new services and gain larger market share should be()
