July 9th 1999: At a meeting held in Sophia Antipolis, 6-7 July
1999, the Third Generation Partnership Project (3GPP)* accepted the
recommendations of the Operators Harmonization Group (OHG) and agreed
to produce standards for the Direct Sequence and Time Division Duplex
(TDD) modes. The results form part of the ongoing work on the ITU
According to the agreement, 3GPP will cover the technical issues relating
to the development of the Direct Sequence and Time Division Duplex (TDD)
modes that form part of the harmonized global 3G CDMA standard. The work
will also include the inter-working between the evolved ANSI-41 and GSM
In order to work towards global harmonization, 3GPP has changed
the chip rate of its standard from 4.09 to 3.84 and adopted a new
downlink pilot structure. These two changes come in addition to the
asynchronous/synchronous base station operation previously adopted. The
complete 3G standards will ensure global roaming and seamless service
The six Standards Development Organizations (SDOs) and three Market
Representation Partners (MRPs) from around the globe that drive the
standardization of the Direct Sequence and TDD modes have agreed
to concentrate their efforts in the 3GPP. This will reduce cost and
avoid duplication of work and result in single set of standards for
use throughout the world. Under the 3GPP agreement each SDO agrees to
publish these standards following their approval process. In Europe,
these will be published by ETSI as UMTS standards.
In order to meet market requirements that have been submitted to the
3GPP by its Market Representation Partners, the 3GPP has established an
aggressive schedule of annual releases for the development of the 3GPP
standards. Release 1999 will be completed by 31 December 1999 and will be
first deployed in early 2001 in Japan. Release 2000 will include Internet
Protocol based networks and will be rolled out around the globe in
2002. Further enhancements will be included in subsequent annual releases.
The meeting schedule until the end of 1999 calls for a workshop to be
held on 24-26 August in Sophia Antipolis, France to discuss the necessary
modifications required for the Direct Sequence and TDD modes to operate on
ANSI-41 based networks. This workshop is open to all interested parties
including 3GPP2 and UWCC participants; consult www.3gpp.org for how to
participate. Radio Access Network working groups will then meet on 3
and 23 September 1999 to determine the updates required to the radio
interface that will be submitted for approval in October 1999.
3GPP has also established appropriate technical liaisons with 3GPP2,
ITU and other bodies to collaborate in the production of global standards.
SDO and MRP members have committed required resources to 3GPP in order
to reduce the time to market. Over 1000 technical experts from around
the globe are engaged in this global 3GPP collaborating to produce
standards and more than 300 of these will be dedicated to the elaboration
of the radio interface aspects. In addition, the 3GPP benefits from
a Mobile Competence Centre, funded to the amount of 7 million EUROs
by the SDOs. This Competence Centre draws together 30 full-time staff
augmented by experts from the SDOs that will provide logistical support
to accelerate the standards process and achieve global business needs.
The UMTS Forum is a market representation partner within 3GPP, and
was represented at the Sophia Antipolis meeting by Dr Bernd Eylert
(UMTS Forum Chairman), Paula Tonelli (Vodafone Airtouch) and Antonella

The six Standards Development Organizations are:
The Association of Radio Industries and Businesses (ARIB) was chartered
by the Minister of Posts and Telecommunications, Japan as a public service
corporation on May 15, 1995. ARIB has about 300 members including both
Japanese firms and overseas firms. For details see www.arib.or.jp.
China Wireless Telecommunication Standard (CWTS) is the Standard
Development Organization (SDO) responsible for wireless standardization
in China as approved by the Ministry of Information Industry (MII).
ETSI unites nearly 700 members from 50 countries, representing
administrations, network operators, manufacturers, service providers and
users. It plays a major role in developing a wide range of standards and
other technical documentation as Europes contribution to world-wide
standardization in Telecommunications and Information Technology. For
details see www.etsi.org.
CommiteeT1 develops standards and technical reports related to, among
others, wireless and/or mobile services and systems, including service
descriptions and wireless technologies. This committee develops and
recommends positions on related subjects under consideration in other
North American, regional and international standards bodies. For details
TTA is the SDO authorized by the Ministry of Information and
Communication for standardization activities in Korea and represents
150 members. For details see www.tta.or.kr.
The purpose of TTC, Japan is to contribute to standardization in
the field of telecommunications by establishing protocols and standards
for connection between telecommunications networks, terminal equipment
and a telecommunications network, etc., as well as to disseminate those
standards. It has 160 members. For details see www.ttc.or.jp.
