CDMA2000 PACKET DATA ROAMING EXCHANGE APPROVED FOR CARRIER IMPLEMENTATION

HONG KONG, Calif., Nov. 17, 2004 – The CDMA Development Group (CDG) (www.cdg.org) today announced the completion of the CDMA Packet Data Roaming Exchange (CRX) specification. CRX is now available for carriers to implement into their CDMA2000® networks.

Currently there are more than 127 million CDMA2000 subscribers worldwide. These customers have accelerated the use of packet data in their home networks. It is a natural next step to enable these enhanced high-speed packet data applications around the globe.

The specification covers network interconnection, RADIUS messaging, use of packet data applications while roaming, data exchange between third parties, data clearing and settlement, service scheduling, and service migration for Interstandard CDMA2000/GPRS packet data roaming.

“CRX accelerates packet data implementations for CDMA2000 through the establishment of an efficient seamless framework that provides both direct connections and third party connections for CDMA2000 operators throughout the world,” said Perry LaForge, executive director of the CDG. “CRX is an example of the roaming solutions that the CDG is introducing to meet the needs of the expanding base of CDMA2000 users.”

Global carriers and vendors should contact the CDG for more information on how to participate and contribute to this CDMA2000 packet data roaming community.

Further information on CDMA technology and international roaming is available on the CDG Web site at www.cdg.org.
