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)
