NGN Next Generation Networks.ppt 0 NGN Next Generation Network Bayram Akbari Slide 2 NGN Next Generation Networks.ppt 1 Agenda. Principles of telecommunication networks Existing networks Drivers and motivation for Next Generation Network Basic concept of Next Generation Network - requirements - functions and structures Next Generation Network benefits Transition to Next Generation Network Bayram Akbari Slide 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 Slide 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 Slide 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 Slide 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 Slide 7 NGN Next Generation Networks.ppt 6 Basic concept of Next Generation Network. An IP-based NGN is able to support a broad variety of services. Variety of services Voice over IP Data Multimedia Bayram Akbari Slide 8 NGN Next Generation Networks.ppt 7 Basic concept of Next Generation Network. Next Generation Network has to fulfill the specific characteristics of telecommunication services. provide a directory ensure privacy/security manage the transfer / delivery of the content collect usage data to ensure service fulfillment and to allow for billing establish communication to the desired partner characteristics of telecommunication services Bayram Akbari Slide 9 NGN Next Generation Networks.ppt 8 NGN architecture generalized in four layers Network services Network control and management Core network Access network Bayram Akbari Slide 10 Interfaces Switching Call Control Application & Service Control Server IP Routing Gateways PSTN Switch NGN Components NGN v/s PSTN- 90 degree shift SDH Transport with Overlay packets for data Common IP MPLS/Ethernet Transport NGN Next Generation Networks.ppt 9 Bayram Akbari Slide 11 Gateways Internet Wireless POTS Integrated Services Over IP Evolving towards Flat All IP Communications Next Generation Networks (NGN) Present Day Networks Next Generation Networks Technological Evolution Bayram Akbari Slide 12 NGN Next Generation Networks.ppt 11 IADAMG BroadBand Access UMG PLMN/3G SGTMG PSTN UMG Service Management Packet Core Network Network Control Core Switching Edge Access SoftSwitch iOSS Policy Server Application Server SCP Location Server RADIUS Server MRS NGN Network Architecture Bayram Akbari Slide 13 4KHz 1100 kHz ADSL 0 kHz 3.4 kHz Voice/Fax 25 kHz Slide 14 A typical ADSL equipment configuration.
