Eric, << An interesting comment ... came from Ericsson, ... the trend towards "all-IP networks." This could explain why Japan Telecom in particular would be interested in wireless VoIP: unlike CDMA carriers upgrading to cdma2000 and GSM carriers moving towards W-CDMA, being a PDC operator, they're going to have to build an entire 3G core from scratch; and lacking the nearly unlimited resources that its main PDC rival DoCoMo has to handle this task, the concept of an all-IP network has to sound alluring to them >> DoCoMo too (article below). Leading the way as always, speaking of "nearly unlimited resources". In addition, part of the work in progress within 3GPP in UMTS 'R2000' is related to at least the beginnings of standardization of the move to an "all-IP network",a nd of course DoCoMO has taken a leadership role there. I'm also under the impression Lucent will be piloting an IP Network with Verizon soon. As early as it might sound, VoIP, is on every bodies charts right beyond Mobile IP. >> MOTOROLA NABS CONTRACT FOR DOCOMO'S WIRELESS IP NETWORK IN JAPAN Loring Wirbel July 24, 2000, Issue: 1123 Section: Business techweb.com ARLINGTON HEIGHTS, ILL. - Motorola Inc.'s Network Solutions Sector will play a key role in the Internet Protocol Core Network of NTT Docomo as the Japan service provider moves from its current i-Mode narrowband data service to a wideband code-division multiple access data service for wireless networks. Motorola will work with Cisco Systems Inc. and Xybridge Technologies Inc. to develop the packet wireline infrastructure for Docomo's wireless service. Motorola and Cisco have worked together since February 1999 to develop what they call the Public Switched Data Network infrastructure, bringing together Cisco routers and packet switches with Motorola base-stations, home location register/visitor location register systems, and network servers. At last fall's Telecom '99 show in Geneva, Motorola laid out Aspira, an end-to-end architecture for wireless IP services based on its joint work with Cisco (San Jose, Calif.). Meanwhile, Xybridge is providing a soft-switch software suite for the Motorola and Cisco hardware, based on the company's Universal Services Suite of soft-switch applications. Even though soft switches have proven themselves in wireline applications, Jawad Ayaz, chief executive of Xybridge (Richardson, Texas), said, "we are excited to demonstrate the soft-switch model in a 3G wireless environment." Motorola will help Xybridge develop specific soft-switch call features for Docomo's wireless environment. Keeping Mum Docomo is keeping mum on total contract size, but says the architecture of the three suppliers will be used in the Japan IP Core Network trials, to be conducted at Docomo labs beginning in September. W-CDMA services are to be rolled out in the second quarter of 2001. If trials go as planned, the Motorola, Cisco and Xybridge equipment will be standardized in that third-generation network. Simon Leung, corporate vice president and general manager of Asia Pacific solutions at Motorola, said he anticipates specific rollout contracts to quickly follow the conclusion of Docomo network trials in March. Jon Shantz, vice president of market development at Cisco, said NTT Docomo showed its "progressive" nature in bypassing the Wireless Application Protocol in its i-Mode service, and has further leaped ahead by opting for a full IP protocol suite in the Aspira network. "I absolutely believe we are putting a stake in the ground in moving beyond the incrementalism of WAP to the full seamless connection to the Internet which a deep IP stack can provide," Shantz said. Leung said the Aspira network is not specific to wireless packet services, and could be used as a unified backbone for Docomo to bring together in a single net 3G traffic, cable modem or DSL traffic, and broadband wireless access traffic. << - Eric (other) -
