NGN is a "Next Generation Network" or the "New Generation Network" acronym. NGN softswitch core is able to provide voice, video, data and other multimedia integrated services, using open, standard architecture to provide rich next-generation network. Packet-based network to provide telecommunications services; use of multiple broadband QoS guaranteed capacity and transmission technology; its business-related functions independent of their transmission technology. NGN enables the user to free access to different service providers; NGN supports generalized mobility. It is a milestone in telecommunications history, marking the era of next-generation telecommunications networks.
NGN – Next Generation Network MSD conference, Lisbon, October 2005. Stephan Berg, Deutsche Telekom Headquarters 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 Konzernentwicklung · NGN – Next Generation Networks.ppt 1 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) access line Packet switched network (schematic) access line Konzernentwicklung · NGN – Next Generation Networks.ppt 2 Existing networks. Today operators run different networks which are interconnected. Variety of networks e.g. PSTN e.g. GSM e.g. Internet Central Functions Central Functions Services Services Services Services Services Services Control Control Control Control Control Control Transport Transport Transport Transport Transport Transport Access Access fixed voice mobile voice different services circuit switched circuit switched packet switched monolithic structure monolithic structure modular structure Konzernentwicklung · NGN – Next Generation Networks.ppt 3 Drivers and motivation for NGN deployment. External drivers and internal motivation put pressure on operators’ NGN deployments. Drivers Operators’ Motivation massive growth of data traffic develop new services easier and faster flat growth of voice market enhance flexibility massive access competition reduce operational expenditures maturity of IP technology replace of old platforms at their open standards and end of lifecycle architectures Deployment of Next Generation Network Konzernentwicklung · NGN – Next Generation Networks.ppt 4 Basic concept of Next Generation Network. A Next Generation Network can be defined by six key criteria. packet- oriented network integration of support existing broad variety infrastructure of services NGN concept application openness focused - and flexibility access regarding independent separation new services into different layers using open interfaces Konzernentwicklung · NGN – Next Generation Networks.ppt 5 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 Konzernentwicklung · NGN – Next Generation Networks.ppt 6 Basic concept of Next Generation Network. Next Generation Network has to fulfill the specific characteristics of telecommunication services. establish communication to the desired partner manage the provide a transfer / directory delivery of the content characteristics of telecommunication services collect usage data to ensure ensure service privacy/security fulfillment and to allow for billing Konzernentwicklung · NGN – Next Generation Networks.ppt 7 Basic concept of Next Generation Network.

Overlay approach is an option that allows for a smooth and flexible transition to NGN . NGN overlay Description ILL US TR PSTN and PLMN remain the key AT IVE production platforms for pure voice CS - Domain services Other NGN overlay platform is used to SDH PSTN / PLMN serve business and consumer customers with integrated services NGN overlay will be further PS - Domain developed in line with market Other SDP NGN requirements Substitution will not be started as IMS long as financial assessment is WWW yielding no incentive or technical IP IP- Phone reasons (e.g. failure rate of components or lack of system support) makes it necessary Konzernentwicklung · NGN – Next Generation Networks.ppt 10 Contact.
