New NGN Specs Entering ITU Approval in August
Geneva - A raft of new NGN (Next Generation Networks) specifications and reference materials will enter ITU’s 4-week approval process in August. If approved, they will set the stage in the fall and 2007 for the next array of global NGN standards under development.

ITU’s lead NGN study group (SG13) gave a preliminary nod to 14 draft recommendations for NGN, including 2 supplements, said a developing country delegate to the ITU. Two proposals have regulatory implications, so they will be considered under the traditional approval process (TAP). Final TAP approval could come in April 2007. NGN work done at ITU includes the requirements and some architecture, officials said. “ITU-T is trying to provide a global perspective on NGN,” said John Visser of Nortel but speaking as chmn. of ITU-T SG19.
The global focus includes significant contributions to the NGN work by ETSI TIPSAN (European Telecommunications Standards Institute - Telecommunication & Internet Converged Services & Protocols for Advanced Networking) and from Asia, N. America and other regions, officials said. Vendors want global standards to sell to every market. Varying subsets and options likely will apply in individual markets, use of one standard for every market is expected to cut business and consumer costs across the board, officials said.
Mobility management requirements were approved in SG19, officials said. SG19 completed the “Mobility Management Requirements for NGN” (Q.1706), also expected to enter ITU’s 4-week review mid-August. That item describes requirements for mobility management in NGN. Officials hope to wrap up recommendations for the mobility management framework at an April 2007 SG19 meeting.
Some of the global NGN specs are built on the work of standards development organizations like the 3rd Generation Partnership Project (3GPP) in Europe and the 4rd Generation Partnership Project 2 (3GPP2) in the U.S. For example, SG19 consented to Rec. Q.1742.5, “IMT-2000 References to ANSI-41 evolved Core Network with cdma2000 Access Network,” Visser said. This spec makes reference to work in other groups. “What we're doing here in the Q.1740 series, Q.1741 series and Q.1742 series is providing an overview of what these releases or ’snapshots’ are, a brief description of each of the parts and references to where you can find the precise texts that make up the whole,” said Visser. Q.1742.5 cites 3GPP2’s work and Q.1741.5 cites 3GPP’s current work.
The 3GPP2 work involves the China Communications Standards Assn. (CCSA), Telecommunications Industry Assn. (TIA), Assn. of Radio Industries & Businesses (ARIB), Telecommunications Technology Assn. (TTA) and Telecommunication Technology Committee (TTC). ETSI and Alliance for Telecommunications Industry Solutions (ATIS) are observers. For 3GPP: ATIS (formerly Committee T1), ETSI, CCSA, TTA, TTC and ARIB, with TIA as an observer.
“There might have been 2 [Resource Control Protocol] recommendations consented at this meeting [SG11], but it seems more likely that there'll be an interim working party meeting,” in late October or early November, at which the body is expected to vote on the recommendation, an official said.
An informal 2-week NGN/Global Standards Initiative meeting of SG reporting members starts Oct. 23 in Geneva, said officials. Another is set tentatively for January. NGN study groups SG19, SG13 and SG11 next meet formally in April in Geneva.
