“A Wireless Focus”
Standards Mean BusinessA Standard Should:
• Be Responsive to Business Processes
• Define Service and Performance Requirements
• Be Timely
• Ensure Interoperability
A Successful Development Process Avoids Duplication and Assures Implementation!
“In the Beginning” A Successful Initial Response to a Burgeoning
Wireless Industry:
• User Requirements set by Users (CTIA)
• Joint activities between SDO’s (ATIS and TIA)– Responded quickly with uniform specifications– Interfaced with Existing Landline Infrastructure– Wireless Standard Adopted by FCC (Part 22) – Address National Issues
• Wiretap • E9-1-1 • LNP • TTY
“Wireless Growth”
• Unprecedented Growth Rate in Wireless Created Demand for:
– Greater Capacity– More Services and Features– Global Interoperability
• Industry Responds with Personal Communications Service (PCS)
“The Digital Meltdown”
Challenges To Interoperability
Response to Capacity Creates Digital Variances: GSM vs. TDMA vs. CDMA
• Industry Realigns; User Requirements Now Set By Interest Groups. – GSMA (GSM)– UWCC (TDMA, renamed 3G Americas) – CDG (CDMA)
“Global SDOs”Competition for Global Interoperability Causes
Regional SDO’s to Partner Internationally– 3GPP (GSM):
• ATIS T1; North America ETSI; Europe
• ARIB; Japan TTC; Japan
• CWTS; China TTA; Korea
– 3GPP2 (CDMA):• TIA; North America ARIB; Japan
• CWTS; China TTC; JapanTTA;
Korea
HarmonizationHarmonization Would Move GSM and CDMA
Standards To One Common Body
However!!
• Strong Regional Economic Interests Will Prevent Full Harmonization
• Globalization Will Not Dissipate Regionalization – Geopolitical Issues– Demographics– Business Interests of “Powerful” Companies
HarmonizationLimited Cooperation Does Exists Between 3GPP
and 3GPP2!!
• Both plan to migrate to All IP - All the TimeData, Voice, Signaling (Relies on IETF protocols)
• Both met at the IP Core Network Harmonization Workshop sponsored by IETF and MWIF, April 2002
• 3GPP and 3GPP2 will continue to co-exist for the foreseeable future
“A Wireless Focus”Other 3G Applications On the Horizon May/Will
Include:
– HS Access to the World Wide WebSuccessful applications will be XML based programming
interfaces and open standards!!
– VoIP– Multimedia Messaging Services (MMS) – Commercial Location Services
How Do We Proceed?
• Strong Business and Service Requirements Drive 3G / 4G Features...What was once a Novelty is now Mission Critical!
• A Traditional “Consensus” (ANSI) Approach to Standards Development is Required But, They Must Be Timely and Implementable to support the dynamic, technical evolution!
How Do We Proceed?Alternative Approach to Standards:
• Different and Diverse
• Broad Consensus
• Individual Representation
• OK for Static and Local IT Systems Since (Internet Is Not One, Uniform Network)
• Generally difficult and not implementable For Telecommunications Systems Where Continuous Availability Is Critical.
SolutionATIS Approach to Standards
• Identify Priorities - User Input• Identify Essential Technical Requirements
• Determine [SDO] Gaps
• Coordinate and Monitor The Work Effort – Avoid Duplication!
– Establish Time Lines
– Test for Interoperability
