  1. Promising services to boost NGN Helmut Schink VP Network Standards, Siemens ICN

  2. Support of different service quality Mobility & Security Dynamic Delivery Of New Services Remotely Managed & Upgradable Internet Enabled devices Connectivity to Multiple devices on Home Network Networking Within the home Broadband Connectivity to One Device Modem Router Service gateways Evolution of CPE devices 1999 2000 2001 2002 2003 Workshop on Next Generation Networks: What, When & How?

  3. Intelligent Services Gateway Interface to Application Domains Home Gateway External BB network Home Security Wireless Connectivity Home Management Communications, Information, Work-At-Home, Education Entertainment Workshop on Next Generation Networks: What, When & How?

  4. xDSL POTS ISDN-BA ISDN-PRA V5.x E1 / LL Multiservice accessThe DSLAM grows up! Residential Splitter /Modem Multi-service access combines voice and data access capabilities in a single backbone Bundle DSL with a new POTS proposition and get rid of legacy features!!! Advancedresidential – SME Homegate-way WLAN BS Phase 2: Packed-based backbone for voice and data Evolution and gradual DLE replacement Phase 1: Separate backbones for voice and data Initial DSL roll-out Media Gateway Controller Signaling Gateway Call Feature Server Voice MGCP / H.248 TDM network Data Voice and Data IP network Any DSLAM QoS IP network Workshop on Next Generation Networks: What, When & How?

  5. 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 Workshop on Next Generation Networks: What, When & How?

  8. 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 towards value-added services Services Business vision Key requirements Mission critical businessapplications Business specific applications Customerconfidence Value-added services e-Commerce Web hosting IP VPN Availability Reliability Businessleadership (innovations) Customer service Security QoS Differentiation: Business opportunity IP networking Operationalleadership Transport service Commodities Workshop on Next Generation Networks: What, When & How?

  9. VOIP VPN 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 Best effort Workshop on Next Generation Networks: What, When & How?

  10. 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 Contentdomain • 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 • Ease of management Access IP Core On the Move WLAN VPN POTS/ ISDN PSTNHome ATM / Ethernet WLAN BS Broad-bandhome,SME Edge Router xDSL (MPLS)Core HGW The New Broadband Service Control Architecture Service Intelligence Domain Network / service management Policy management (service control) Workshop on Next Generation Networks: What, When & How?

  11. 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 IP Core Edge Router (MPLS) Core BRAS Opera Browser Workshop on Next Generation Networks: What, When & How?

  12. Voice Softswitch other SIP Apps. 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 Service Intelligence SIP-T SIP-T SIP Service Selection Control SIP Proxy PSTN / PLMN MGCP/H.248 SIP Service Delivery Domain Access IP Core On the Move WLAN VPN POTS/ ISDN PSTNHome ATM / Ethernet WLAN BS Broad-bandhome,SME Edge Router xDSL (MPLS)Core HGW The New Broadband Service Control Architecture (Session Control) Workshop on Next Generation Networks: What, When & How?
