  • 11. WHO ARE THE BENIFICIARIES OF A CONVERGED NETWORK• CITIZEN & GOVERNMENT OF THAT COUNTRY• WHY?• CUSTOMERS WILL BE BENEFITTED WITH HAVING ONE TERMINAL TO OPERATE ALL VOICE , DATA & VEDIO SERVICES. FURTHER THEY WILL BE BENIFITTED WITH HAVING ONE ACCESS LINE TO MAINTAIN AT HOME.• CUSTOMERS CAN CHOOSE THE SERVICES INDEPENDENT OF THE NETWORK PROVIDER, AND THE SERVICE PROVIDER CAN ATTRACT THE CUSTOMERS ON BETTER VALUE PROGRAMMES, INDEPENDENT TO THE NETWOPRK PROVIDER.• IS SERVICE & NETWORK PROVIDERS ARE BENIFITTED?• YES. CUSTOMERS WILL BE ATTRACTED TO THE INOVATIVE PRODUCTS

  • 27. Definition of NGN NGNs essentially involve the replacement of all the different legacy networks with a single unified network, based on Internet protocol (IP) technology, which will provide all the different types. of services. The International Telecommunications Union (ITU) provides the following more formal definition of NGN in its Y.2001 Recommendation: A Next Generation Networks (NGN) is a packet-based network able to provide Telecommunication Services to users and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent of the underlying transport-related technologies. It enables unfettered access for users to networks and to competing service providers and services of their choice. It supports generalised mobility which will allow consistent and ubiquitous provision of services to users. ITU-T Recommendation Y.2001, ITU, December 2004 – General overview of NGN
