Pstn evolution

PSTN evolution

  • The classical PSTN market is stagnating

  • Obsolescence is not key, but lack of flexibility within current PSTN network is a limiting factor

  • Main threat for PSTN operators:

  • Shift of telephony services to other infrastructure providers

  • Main opportunity for PSTN operators:Migration of existing infrastructure towards broadband

  • Voice drives the revenues of the telcos, but focus for investment is NGN

  • Media gateways, call feature servers, and signaling gateways are the key building blocks of a multi-service architecture

Towards value added services

  • Value-added services will become the main differentiator

  • Most added value services are based on voice, data, andmobility convergence and require support beyond best effort

The new service architecture

VOIP

GAMING

INET

The new service architecture

The service architecture delivers:

  • Service models focusing on the experience, not the connection

  • Business models that are flexible and easily adaptable

    • Different services for different markets with different billing

    • Simultaneously delivery of:

      • Low volume / high margin services

      • High volume / lower margin services

  • Drive model from bits to experiences

  • Product creation and definition for fast market trial

Service Models

Assured experience

Better than best effort

  • The "IN" of the data network

  • Virtualization of the service

    • Customer-centric view

  • Manage services, not bits

  • Real time changes to theconnection between

    • Customer and content, or

    • Customer and customer

Service Delivery Domain

  • Delivers scalability and reach

    • "Any Access"

    • DSL & WLAN

  • Service Resiliency

  • Carrier-, not enterprise-focused

  • Performance for all traffic types

  • Virtualization of the network

  • Meditation of legacy systems

Example the turbo mode browser talks bras

Demand for more Speed

+ User ID

Contentdomain

Higher Bandwidth

+ Advertising

Example: The Turbo Mode - browser talks BRAS

  • Opens an Ad Window

  • Demands Higher Speed from the Unisphere ERX Router

  • Sends Unique User ID Data to the ISP

  • ISP Allows more Speed and Sends Targeted Advertising

Gaming

e.g. VoD

  • Architecture allows separation of service selection and service interaction

  • Service interaction most probably SIP based

  • Architecture allows controlled access of independent service providers (e.g. gaming, VoD)

    • controlled access b/w

    • controlled QoS

    • billing/accounting possibilities

The 21st Century network architecture ?

  • Co-existence and interworkingof multiple control architectures.

  • PSTN and PLMN will be about for some time

  • Co-existence with NGN

  • Gradual migration of customers

  • Who owns the intelligencewins the revenue !

  • Open service creation environment

  • Agnostic to delivery networks

  • Open interfaces between element layer and OSS

  • Customer centric view

  • Customer access to management

  • Multiple access technologies (WLAN, xDSL, GE, …)

  • DSLAM is evolving into the prime multi-serviceaccess gateway

  • Multi-Service Integration on the optical layer

  • Dynamic assignment of capacity

  • Low end CPE - a commodity

  • High end CPE - multi service platform, mobility, security and managed

  • Customer lock-in by delivering managed services

  • Becomes commodity

  • GE and Lambda products in metro

  • Legacy ATM access

  • QoS support

Not to forget

Not to forget

  • Basic services need to be

    • interoperable

    • easy to use

    • affordable

  • Differentiation needs to be supported for

    • businesses

    • high end users
