TAILIEUCHUNG - Signaling System No.7 Protocol Architecture And Sevices part 6

Regional Standards North America, Europe, and Japan play a major role in the ITU-T and also set their own regional standards based on the ITU-T recommendations.

ETSI ETSI is a nonprofit organization responsible for setting standards for telecommunications systems in Europe. ETSI was set up by the CEC Commission of the European Communities . ETSI is an open forum that unites 728 members from 51 countries representing administrations network operators manufacturers service providers and users. Any European organization proving an interest in promoting European telecommunications standards has the right to represent that interest in ETSI and thus to directly influence the standards-making process. The purpose of ETSI was to create something in between the international level and the national level for pan-European use so that EU member countries could have cross-border signaling that was not as restricted as that found on the international level. 3rd Generation Partnership Project When the ITU solicited solutions to meet the requirements laid down for IMT-2000 3G cellular various standards groups proposed varying technologies. ETSI proposed a Wideband Code Division Multiple Access WCDMA solution using FDD. Japan proposed a WCDMA solution using both TDD and FDD. The Koreans proposed two types of CDMA solutions one similar to the ETSI solution and one more in line with the North American solution CDMA 2000 . Instead of having different regions working alone it was decided that it would be better to pool resources. To this end the 3rd Generation Partnership Project 3GPP was created to work on WCDMA and 3GPP2 was formed to work on CDMA-2000. 3GPP is a collaboration agreement that was established in December 1998. It brings together a number of telecommunications standards bodies called organization partners. The current organization partners are Association of Radio Industries and Businesses ARIB Japan China Wireless Telecommunication Standards group CWTS China European .
