Agenda
• Current situation in standards
• The shape of the standards world
• BT’s 21st Century Network (NGN)
• What are the important standards bodies for the NGN?
• Problems with way standards are developed
• Ways forward to solve problems
• Conclusions
What is the Current situation in Standards?
• Multiple networks exaggerate the cost of multiple standards.
• Cost of interworking is high.
• All telcos under pressure to reduce expense on standards
• Growing complexity from multiple fora
• More and more uses are global (mobile, WLAN, Internet etc) with more and more users travelling.
• Need for a radical drive to the NGN – speed is essential.
• Standards must be global
21C aims
• Revolutionise customer experience– Make it easier to buy and use services
– Enable customers
• Deliver innovative products more rapidly– Rapid service creation & implementation
– With more people creating new services
• Make it simpler to deliver and maintain service– Process, systems & network automation
• Transform the cost base of the Company– Enabler of whole life cost reduction (CAPEX & OPEX)

Why standards…
• To enable new services– must operate on global basis
• To reduce costs– commoditisation of equipment
• To meet regulatory requirements– essential interfaces
• To ensure accessibility/safety/security, etc
Highest Priority 21C Standards Requirements
• Multi-service carrier-scale core– enabled by underlying ‘MPLSv2’ network
• Mobility enabled intelligence– Extending the IMS to Wi-Fi and fixed Broadband access
• PSTN replacement– H248/IP network able to provide telephony features
• 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
Important Standards Bodies for 21CN• ETSI – TISPAN and 3GPP
• ITU – Global standards
• ATIS – US standards priorities
• IETF – IPv6, SIP extensions, MPLS, etc
• TMF, with OSS/J – standardised OSS components
• MSF – Interoperability of VoIP elements of NGN
• Open Mobile Alliance (OMA), with Parlay – (Mobile) Applications, DRM
• Metro Ethernet Forum (MEF) – role of Ethernet in transport network
• DSL forum, DSL and QoS architectures
• IEEE 802.11x – Wi-Fi hotspots
• W3C – Privacy, Web Services
• WiMAX forum
Problems…
• Plethora of Standards Bodies and Fora
• Service Providers don’t have enough influence over standards
• The IETF doesn’t work anymore
• The IPR morass
There are so many standards bodies out there
• CEN/ISSS Consortia Survey– www.cenorm.be/isss
• ETSI FORAwatch– www.etsi.org/forawatch
• Over 500 standards bodies and fora listed
Standards “Food Chain”

ITU-R, ECC, National bodies and EU
Service Providers don’t have enough influence
• SPs used to drive formal standards
• Economic downturn caused SPs to withdraw from standards
• Competitors not collaborators
• IETF working to different business model
IETF doesn’t work anymore
• Developing standards in best interests of the Internet
"The purpose of the IETF is to create high quality, relevant, and
timely standards for the Internet.”
• Dominated by vendors
• Doesn’t listen to Service Providers
The IPR Morass
• Most bodies adopt RAND (or FRAND) policy
• RF is a special case of RAND
• What is “fair and reasonable”?
• What is “essential”?
• What is a late declaration?
• Problem of ambushing (or submarining)
So how can we get the Standards we need to build NGNs?
• Coordinate existing bodies better
• Use formal and informal standards bodies appropriately
• Use bodies such as ATIS to promote needed standards
• Create Service Provider Requirements fora
• Promote fora specifications to formal standards
• Harness the IETF
• Encourage Royalty Free IPR policies
Examples of good coordination
• ICT Standards Board
• Informal Forums Summit
• ISO/IEC/ITU MoU on eCommerce
• Multi-Service Forum (MSF)
ICT Standards Board
• ANEC
• ATM Forum
• CEN
• CENELEC
• DVB
• EBU
• ECBS
• Ecma International
• EFTA Secretariat
• EICTA
• ERTICO
• ETSI
• European Commission
• ISOC (IETF)
• Liberty Alliance
• NORMAPME
• OASIS
• OMA
• OMG
• OSGi
• RosettaNet
• The Open Group
• TMF
• W3C
Why ICTSB?
• Reaction to convergence of information technology, telecommunications, broadcasting and entertainment industries
• Need to reduce overlaps between activities of European Standards Organisations (ESOs)
• Need to involve (many) fora and consortia
• Provide European focus for Global ICT Standardization
What does ICTSB do?
• Analyses requirements from any competent source based on concrete market needs
• Translates these requirements into coherent standards work programmes
• Allocates work items to members and reviews progress against objectives
ICTSB (and WGs) does not produce standards
ICTSFG Report – April 2005
• Structure and organization of ICT standardization at global, regional and national level
• Role of public authorities in ICT standardization, including Government as regulator, enforcer and major procurer
• Economics of ICT standardization, including educational, promotional and awareness issues
• Role of end-users
4 Streams
Relationship between formal and informal bodies
• Fora / consortia should develop more systematic relationships with formal standards bodies
• Formal standards bodies should adopt more pro-active approach towards consortia
• Global consortia should take account of regional dimension
• Co-ordination between consortia and formal SDOs should be improved by encouraging development of issue-specific coordinating bodies
Promoting Forum Specifications to Formal Standards
Examples of successful processes:
• European DVB agreement with ETSI
• Fast track and PAS procedures in ISO/IEC JTC1
• Focus Group (A.7) procedure in ITU-T
Service Provider Requirements groups
• e.g. MPLS & Frame Relay Alliance (MFA)
• FSAN VDSL
• IPsphere is considering– WG Chair model instead?
• Service Providers only?
• Must have formal route into other WGs
• Must not be at expense of Board positions
What to do about IPR?
• Insistence on RF doesn’t work– companies do it outside
• Insist on early declaration
• Encourage RF where possible– e.g. CEN/CENELEC IPR policy:
“If in exceptional cases, technical reasons justify the preparation of a European Standard in terms which include the use of a patented item, there is no objection in principle to such a step, even if the terms are such that there are no alternative means of compliance”
Conclusions
• NGN will only succeed based on globally standardised components
• Standards bodies need to collaborate between fora, regional and global standards bodies
• We should only write the standard once and end point should be global standard in the ITU
• Everyone wins:– vendors
– operators
– users
