Standards Overview
•
Why the standards are needed?
1. Interoperability
2. Quality insurance
3. Consistency in Evolution
• Bodies of standardization
1. International or Government (ITU)
2. Semi-official (ETSI)
3. Volunteer Organizations (3GPP, 3GGP2)

Forums/Consortia cooperating with
ITU
Some of the forums/Consortia that are cooperating with ITU
• ATM Forum
• DSL Forum
• IPv6 Forum
• MPLS Forum
• ETSI
• China Wireless Telecommunication Standard Forum (CWTS)
ETSI History
• Single European Market was created 1987
• Need for Integrated communications infrastructure
• European Comission outlined ”Green Paper”, recommending
the establishment of an organisation to set
telecommunication standard
• Idea was shared by former Auropean Conference for Postal
and Telecommunications Administrations (CEPT)
• European Telecommunication Standardisation Institute (ETSI)
was Born 1988
ETSI Features
• ”Independence, openness and unity”
• Objective is to provide widely implemented technical standards
•
•
Supporting European Union (EU)
Supporting European Free trade Association (EFTA)
• All documentation is in English
• Founded in partnership with European manufacturing industry
and customers
•
•
Contributes to world-wide standardization

ETSI IPR Policy 1/2
• Objectives
•
Use solutions that meet technical objectives of European telco sector
•
Reduce risk that IPR required for implementation of standard would not
be available
•
Seeks balance in-between IPR protection and public standards
• IPR holders should be adequately and fairly rewarded
•
Independent if they are ETSI members or not
• Members providing proposals should inform ETSI if any
essential IPRs are related to the proposal
•
Information provided prior to publication
•
Member refusing to license must consider it’s position
•
3rd party asked for non-discriminatory licensing of technology
•
If licensing not available, modifie so that IPR is no longer essential
ETSI IPR Policy 2/2
• If member id not ready to license IPR, ETSI will review for an
alternative that
•
Is not locked by IPR and satisfies ETSI’s requirements
• ETSI can withhold IPR
• Giving acknowledgement of identified copyrights
• Published standards or technical specification may not be
confidential
• Proceedings can be confidential
• Members may freely reproduce standards for own use
• Distribution is not allowed
• Any violation of policy
• Gives ETSI board a right to decide on action, if any, taken
Current Activities
•
Active on several fields: Aeronautical, Mobile,
Broadcast, Data networks, Radio technology,
Testing, User interfaces, etc.
