3 NGN – Next Generation Networks.ppt 2 Principles of telecommunication networks. Using the same access line, circuit and packet networks utilize different mechanism to provide services and to share resources. Circuit switched network (schematic) Packet switched network (schematic) access line Bayram Akbari

4 NGN – Next Generation Networks.ppt 3 Existing networks. Today operators run different networks which are interconnected.  e.g. GSM  e.g. PSTN  e.g. Internet Central Functions Transport Control Services Transport Control Services Transport Control Services Access Central Functions Transport Control Services Transport Control Services Transport Control Services Access  fixed voice  circuit switched  monolithic structure  mobile voice  circuit switched  monolithic structure  different services  packet switched  modular structure Variety of networks Bayram Akbari

5 NGN – Next Generation Networks.ppt 4 Drivers and motivation for NGN deployment. External drivers and internal motivation put pressure on operators’ NGN deployments.  develop new services easier and faster  enhance flexibility  reduce operational expenditures  replace of old platforms at their end of lifecycle  massive growth of data traffic  flat growth of voice market  massive access competition  maturity of IP technology  open standards and architectures Deployment of Next Generation Network Operators’ MotivationDrivers Bayram Akbari

6 NGN – Next Generation Networks.ppt 5 Basic concept of Next Generation Network. A Next Generation Network can be defined by six key criteria. NGN concept integration of existing infrastructure packet- oriented network support broad variety of services openness and flexibility regarding new services separation into different layers using open interfaces application focused - access independent Bayram Akbari

55 NGN – Next Generation Networks.ppt 54 Basic concept of Next Generation Network. Monolithic networks evolve towards a layered NGN architecture with open interfaces.  Application Plane enables the provisioning of services and provides the control and logic for the execution of services  Control Plane controls the elements of the network, establishes and tears down media connections  Transport Plane is responsible for the transport of media and signaling messages  Management Plane covers network management ensuring service fulfillment, service assurance and billing  Access Networks connect customer networks or terminals with the components of the NGN network and aggregate the dedicated traffic type Planes and functions NGN Planes Access Networks Transport Plane Application Plane Control Plane Management Plane Value Added Service Creation Packet Based Transport Basic control service Bayram Akbari

56 NGN – Next Generation Networks.ppt 55 Next Generation Network benefits. NGN has the potential to become the communication network of the future.  device independence  access independence  service variety  enhanced usability  …  new revenue potential  improves time-to-market  easy integration of 3rd party services  one platform for voice, data and multimedia  … Customer benefitsNext Generation Network Operator / provider benefits IP Access Network … SDP … … … IMS Transport Plane Application Plane Control Plane Management Plane DSLAM Radio Bayram Akbari

57 NGN – Next Generation Networks.ppt 56 Transition to Next Generation Network. Overlay approach is an option that allows for a smooth and flexible transition to NGN.  PSTN and PLMN remain the key production platforms for pure voice services  NGN overlay platform is used to serve business and consumer customers with integrated services  NGN overlay will be further developed in line with market requirements  Substitution will not be started as long as financial assessment is yielding no incentive or technical reasons (e.g. failure rate of components or lack of system support) makes it necessary DescriptionNGN overlay SDP IP CS - Domain IMS Other PSTN / PLMN IP- Phone ILLUSTRATIVE PS - Domain SDH Other NGN WWW Bayram Akbari
