ATLANTA--(BUSINESS WIRE)--March 22, 2004

Siemens Mobile and Ubiquity today announced a strategic partnership for the integration of the Ubiquity SIP Application Server (Session Initiation Protocol) into IMS@vantage, Siemens' IP (Internet Protocol) Multimedia Subsystem (IMS). IMS is a platform that may be used by operators to quickly develop and deploy multimedia services for 2.5G and 3G mobile networks. With Ubiquity's application server, Siemens will be able to offer operators and open application manufacturers (OAMs) a software environment for designing multimedia and telephony services on the basis of SIP, the standard for networks of the future. Several mobile communication operators are already testing Siemens' first services based on the SIP Application Server and IMS@vantage, such as Push and Talk over Cellular (PoC), infotainment and telephone conferencing.

"The partnership between Siemens mobile and Ubiquity promises great synergies as a good illustration of telco vendors leveraging standards-based approaches to bring new services to operators," said Ken Rehbehn, Principal Analyst at Current Analysis. "At the end of the day, it's about increasing average revenue per user (ARPU) by deriving new revenue streams from value-added services. This end-to-end solution from Siemens mobile and Ubiquity for 2.5G and 3G networks helps operators lay a foundation for high-quality data services."

IMS is the new standardized multimedia switching technology for packet-oriented networks and various access technologies, such as UMTS, EDGE, GPRS, and W-LAN. The benefits for the user: Voice and data can be transmitted over the air simultaneously and in any combination. For example, a user can start a game during a mobile phone call and talk about it with the person they are calling. "We believe that the SIP standard will play a major role for transporting real-time multimedia service content in the IMS on 2.5G and 3G networks," explained Christoph Caselitz, President of Networks at Siemens mobile. "Ubiquity's SIP Application Server provides an open environment for developing standards-based applications and fits seamlessly into IMS@vantage."
