Ngn and convegence

  1. 1. Prepared By :- RAHUL KAUSHAL 101020
  2. 2. INTRODUCTION TO NEXT GENERATION NETWORKS <ul><li>A Next Generation Network is a </li></ul><ul><li>– packet-based network able to provide telecommunication services </li></ul><ul><li>– able to make use of multiple broadband access technologies </li></ul><ul><li>– QoS-enabled transport technologies, and </li></ul><ul><li>– in which service-related functions are independent from underlying transport-related technologies </li></ul><ul><li>• It offers unrestricted access by users to different service providers </li></ul><ul><li>• It supports generalized mobility which will allow consistent and ubiquitous provision of services to users </li></ul>
  3. 3. NGN is about simplifying networks
  4. 4. Next generation core networks <ul><li>The next generation core networks are defined on the basis of their underlying technological “components” that include – </li></ul><ul><ul><li>IP-based network: </li></ul></ul><ul><ul><li>Packet-based, multi-purpose: </li></ul></ul><ul><ul><li>Separation of transport and service layer: </li></ul></ul>
  5. 5. Separation of transport and service layer
  6. 6. Typical representation of NGN architecture
  7. 7. What is convergence? <ul><li>The path towards convergence was led mainly by the increasing digitalization of content, the shift towards IP-based networks, the diffusion of high-speed broadband access, and the availability of multi-media communication and computing devices. Convergence is taking place at different levels: </li></ul><ul><li>Network convergence </li></ul><ul><li>Service convergence </li></ul><ul><li>Industry/market convergence </li></ul><ul><li>Device convergence </li></ul><ul><li>Converged user experience </li></ul>
  8. 8. Convergence and NGN <ul><li>Convergence in network technologies, services and in terminal equipment is at the basis of change in innovative offers and new business models in the communications sector. </li></ul><ul><li>The utilization of the term “convergence” represents the shift from the traditional “vertical silos” architecture, i.e. a situation in which different services were provided through separate networks (mobile, fixed, CATV, IP), to a situation in which communication services will be accessed and used seamlessly across different networks and provided over multiple platforms, in an interactive way. </li></ul>
  9. 9. <ul><li>Previously distinct communication networks and services are today converging onto one network, thanks to the digitalization of content, the emergence of IP, and the adoption of high-speed broadband. </li></ul><ul><li>Traditional services such as voice and video are increasingly delivered over IP networks and the development of new platforms is facilitating the provision of converged services. </li></ul><ul><li>These converged services are appearing in markets as &quot;triple&quot; or &quot;quadruple&quot; play offers which provide data, television, fixed and mobile voice services. </li></ul>
