Summary

• Business drivers for NGN
• Requirements for NGN
• Technical view of NGN
• What standards do we need for NGN?
• What do we want from ITU?

3
Whats the Current situation?

• Telecom winter exaggerating the cost of multiple
  standards e.g. multiple networks in mobile
• All telcos under pressure to reduce expenditure
  on standards
• Cost of interworking is killing us
• More and more uses are global (mobile, WLAN,
  Internet etc) with more and more users
  travelling.
• Standards must be global
• Growing complexity from multiple fora as groups
  become frustrated with speed of traditional
  standards bodies
• Need for a radical drive to the NGN speed is
  essential.

4
Why do we need an NGN?

• Make it easier to create new services
• Faster
• More people can create services
• Make it easier to buy and use services
• Give customers greater choice
• Make it simpler to deliver and maintain services
• Process automation
• 30-40 cost reduction

5
What does it mean?

• New services
• Open APIs and applications platforms
• Mobile enabled
• Re-usable components/capabilities
• Build on broadband capability
• Cost reduction
• Not enough to do efficiencies and automation
• Radical network convergence to fewer networks and
  systems carrying more services

6
Cost Reduction

• Efficiencies and automation not enough
• need to enable customers and partners in the
  service management processes
• Radical steps required
• need closure of legacy networks and systems
• Have to include future of PSTN (voice)
• More important to converge in access and backhaul
  than in core
• because opex and capex centred there

21st Century Services Vision
A world where all our customers feel empowered
and are treated as individuals

Frame Relay
ATM
SDH

• Built on servicetechnology stove pipes.
• Every network service has its own network
  platform
• FR, ATM, MPLS IP VPN, Internet, PSTN etc.
• We want a converged multi-service platform to
  deliver all services.

Overall Architecture
12
Highest Priority NGN Standards Requirements

• Multi-service carrier-scale core
• enabled by underlying MPLSv2 network
• 3GPP Architecture
• extended to Wi-Fi and fixed Broadband access
• Session based QoS
• Session Control
• extensions to SIP with full multimedia capability
• Billing and charging (data interchange billing)
  between operators
• Manageability
• commoditised componentised OSS
• Security
• authentication across networks / operators
• Home Gateways/Networks

13
What do we need to do generally..?

• Prioritise.
• Position fora, regional bodies and ITU into a
  consistent approach to lead to global standards
  an architecture of standards bodies.
• Support the NGN architecture will require us to
  merge over traditional boundaries.
• Give equal weight to systems and networks

14
ITU is important to NGN for

• Access Networks SG15
• Core Networks SG13
• Optical Networking SG15
• Spectrum ITU-R
• Numbering Addressing SG2
• Signalling for QoS across multiple networks
  SG11
• Services and applications SG16
• Security SG17
• NGN Focus Group to get it started and bring it
  all together

15
Other Important Bodies for NGN

• 3GPP/TISPAN IMS
• ATIS US carrier requirements
• DSL Forum remote management of CPE
• IETF IPv6, SIP extensions, MPLS, etc
• TMF standardised OSS components
• Open Mobile Alliance (OMA) (Mobile)
  Applications, DRM
• Metro Ethernet Forum (MEF) role of Ethernet in
  transport network
• IEEE 802.11x Wi-Fi hotspots

16
What do we want from ITU?

• Global Standards, speedily and efficiently
  produced
• How do we get this?
• A single ITU-T Study Group for core NGN studies
• A managed release program
• A co-ordinated ITU-T approach

17
Conclusions

• NGN will only succeed if based on globally
  standardised components
• ITU must work with ETSI, ATIS and other fora to
  achieve standards for NGN
• ITU can provide strategic focus for NGN standards
  but must create SG with sufficient critical
  mass to address NGN issues
