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

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

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

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)
