1 Networked Worlds and TISPAN Helmut Schink

2 © Siemens 2 TISPAN NGN Assumptions IP-based network  Characteristics: secure, reliable, trusted  No technological distinction between public and private network Distributed and open control  Adapt to distributed nature of IP networks  Support third party services Independence from transport technology Independence from access technology  Diversity of user equipment  Support of modern access technologies DSL, Cable, WLAN, WiMAX, …)  Inherent mobility support, both of users and devices Clear separation from application plane  Multi-service platform  Enabler of real-time and non-real time services Support of PSTN / ISDN migration

5 © Siemens 5 TISPAN Release 1 Highlights Target date: Summer 2005 Key is adaptation and not modification of IMS QoS is limited to the Access ISDN/PSTN service simulation (in a pure SIP environment) and emulation (e.g. softswitch environment) are both supported as separate subsystems xDSL, WLAN, 3GPP and customer LAN access supported, Cable may be included if someone offers to do the work. Services are offered through external applications, not embedded as capabilities in control protocols Major service capabilities: Conversational, Presence and IM, Content delivery (incl. Video), PSTN/ISDN migration and internet type services

6 © Siemens 6 NGN Release 1 Packages Package 1.1:  Service requirements and capabilities  Service descriptions  Overall and Sub-systems Architecture Package 1.2:  Detailed functional requirements  Specific Services/Suppl. Services definitions  Protocol specifications for Emulation and for IMS  Interworking specifications and testing Package 1.3:  Other requirements and architecture  Protocols  OSS Package 1.0 (GEN):  Scope/Directions, Terminology  Qos/ Security/ Management Framework  ENUM-related

9 © Siemens 9 Possible consequences for „Governance“ From Internet Governance towards NGN Governance  based on assumption of multi-purpose electronic communication  IP addresses, names, port numbers  telefone numbers  frequencies  difficulty to distinguish between private and public  different players on the market:  from ISPs towards telcos??  from nerds to couch potatoes  spoil over from Internet treats towards telco:  spam for voice  virus on telephone

10 © Siemens 10 What does it mean Need to consider layered governamce model:  Layer 1: Network layer infratstructure (root server, DNS, IP and E.164 addresses, protocols, RFID #, MAC, presence ID,.....)  Layer 2: Infra-Services (whois, yellow pages, dispute resolution, multilinguism,....)  Layer 3: Application-related features (spam, illegal and harmful content, privacy, IPR/DRM Required actions:  Identify issues, status, major players and gaps (see e.g. ICC´s issue matrix and gap analysis  allocate new/enhanced tasks to appr. organisations (via WGIG)
