Siemens Mobile today announced that it successfully placed one of the first Internet Protocol-based (IP) Multimedia Subsystem (IMS) phone calls on a live GSM network in the United States.

This mobile milestone was accomplished using advanced wireless network infrastructure technology from Siemens, known as IMS@vantage, to deliver instant messaging, interactive mobile gaming, friend list/network presence detection, video telephony, Push and Talk over Cellular (PoC), and a variety of other advanced multimedia services.

One of the most attractive features of IMS is that it allows a smooth evolution to third generation (3G) network infrastructure. Network operators with 2.5G infrastructure can take the first step to 3G by deploying IMS, thereby enabling a suite of multimedia and multi-session applications.

 For example, IMS allows several Internet Protocol (IP) media streams in one session, enabling the integration of a voice call and an interactive gaming experience on a mobile device at the same time.

The IMS platform is technology agnostic, allowing easy interoperability with a variety of technology platforms including GSM/GPRS/EDGE, WLAN, CDMA/1X and UMTS.

To further demonstrate its wide array of network infrastructure technology, Siemens recently introduced its Wireless Solutions Showcase laboratory in its Boca Raton, Florida facility.

This laboratory combines a dedicated development and support team with a standards-compliant service delivery ecosystem, which, for example, enables IMS/SIP, messaging and location-based applications.
