Existing networks.Today operators run different networks which are interconnected.

Variety of networks

  • e.g. PSTN
  • e.g. GSM
  • e.g. Internet
  • fixed voice
  • circuit switched
  • monolithic structure
  • mobile voice
  • circuit switched
  • monolithic structure
  • different services
  • packet switched
  • modular structure

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
  • flat growth of voice market
  • massive access competition
  • maturity of IP technology
  • open standards and architectures
  • develop new services easier and faster
  • enhance flexibility
  • reduce operational expenditures
  • replace of old platforms at their end of lifecycle

Deployment of Next Generation Network

slide6
Basic concept of Next Generation Network.A Next Generation Network can be defined by six key criteria.

packet-oriented network

support broad variety of services

integration of existing infrastructure

NGNconcept

openness and flexibility regarding new services

application focused - access independent

separation into different layers using open interfaces

slide7
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

slide8

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 transfer / delivery of the content

provide a directory

characteristics of telecommunication services

ensure privacy/security

collect usage data to ensure service fulfillment and to allow for billing

slide9
Basic concept of Next Generation Network.Monolithic networks evolve towards a layered NGN architecture with open interfaces.

NGN Planes

Planes and functions

  • 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

Next Generation Network benefits.NGN has the potential to become the communication network of the future.

Next Generation Network

Customer benefits

  • device independence
  • access independence
  • service variety
  • enhanced usability

Operator / provider benefits

Transport Plane

IP

  • new revenue potential
  • improves time-to-market
  • easy integration of 3rd party services
  • one platform for voice, data and multimedia

slide11
Transition to Next Generation Network.Overlay approach is an option that allows for a smooth and flexible transition to NGN .

NGN overlay

Description

  • 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
