Motorola Mobile VoIP Service on End-to-End CDMA 1xEV-DO

[Barry]

Motorola?s fully integrated end-to-end CDMA 1xEV-DO solution, coupled with its IP Multimedia Subsystem (IMS), will give attendees at CTIA Wireless a hands-on experience with VoIP calls, mobile broadband applications on a Motorola handset, and web browsing in a home environment.

With CDMA 1xEV-DO network operators can provide high-speed wireless data and applications to subscribers on the move, delivering content to their mobile handsets, PDAs or laptops, or to residential broadband users seeking multi-media information and entertainment.

The Motorola IMS, based on Motorola's SoftSwitch technology, gives wireless operators the ability to migrate to fully converged networks that can handle synchronized voice, data, and multimedia applications. Motorola?s IP technology, as the basis for its Push-To-Talk over Cellular and Motorola Softswitch (MSS) products, has been deployed in several large-scale commercial operations that together support more than 2.5 million subscribers. At CTIA multiple types of devices (GSM, CDMA and WiFi) will be used in the demonstrations to illustrate packet to circuit switch calling, one of the many functions made possible by the IMS.

The Motorola IMS is designed to be a robust and highly scalable carrier-grade system that enables convergent VoIP across multiple access domains and open interfaces to third-party applications servers. This convergence will enable a vast array of applications that will enhance personal collaboration, enhanced call management and video services as end-users move among various environments using fixed and mobile devices.
