Summary:Today's wireless core network is based on a circuit-switched SS7
architecture similar to that found in wireline telecommunications
networks. With the advent of IP technologies and the tremendous growth
in data traffic, the wireless industry is evolving its core networks
toward IP technology. Wireless telecommunications started as an offshoot
of wireline telephony, and the absence of global standards resulted in
regional standardization. Two major mobile telecommunications standards
have dominated the global wireless market, namely, TDMA/CDMA developed
by the TIA in North America and GSM developed by the ETSI in Europe. As
we move toward third-generation wireless, there is a need to develop
standards which are more global and collaborative. The global wireless
industry has created two new global partnership projects, SGPP and
3GPP2, to address the issue of the limited data capabilities of 2G
systems, motivating the partnership projects (PPs) to start work on 3G
wideband radio technologies that can provide higher data rates. This
work resulted in 3G wireless radio technologies that will provide data
rates of 144 kb/s for vehicular, 384 kb/s for pedestrian, and 2 Mb/s for
indoor environments, and meet the ITU IMT-2000 requirements. Now that
the radio technology standards to support higher data rates have been
developed, the PPs are focusing on development of standards for all-IP
networks. We discuss the genesis of 3GPP and 3GPP2 IP work, outlining
the important architectural differences of the two groups. Currently,
3GPP and 3GPP2 offer divergent proposals that need to be harmonized if
convergence toward an IP-based mobile telecommunications networks is to
become a reality
