ITU-T's Study Group 19, in its first meeting of the new study period held in Geneva, December 2004, completed the first stage of approval for the latest standards for the core network infrastructure for next generation mobile telephony (ITU's international mobile telecommunications-2000 (IMT-2000)).
This set of specifications makes use of American National Standards Institute (ANSI) core network specifications (supporting the cdma2000 air interface). The standards will be known as ITU-T Recommendation Q.1742.4, and extend the applicability of this ANSI standard to a global market.
Together with matching radio interface specifications handled through ITU-R Working Party 8F in the ITU-R M.1457 series of Recommendations, these standards support applications ranging from narrow-band voice to wide-band voice, data and multimedia communications with full terminal mobility. Completion of the approval process is anticipated in the first quarter of 2005.
