New Orleans, CTIA -- In an industry-first, Ericsson today demonstrates cross-technology push-to-talk over CDMA2000 and GSM/GPRS at the CTIA telecom event in New Orleans. The new Ericsson Instant Talk solution is built on Ericsson's IP Multimedia (IPMM) platform, delivering cost-effective and future-proof IP infrastructure to operators.

Ericsson Instant Talk is based on the IP Multimedia System (IMS) core network open interfaces and is developed to work across GSM/GPRS, EDGE, CDMA2000, WCDMA and WLAN networks. The Ericsson Instant Talk solution will offer push-to-talk functionality combined with presence services. The solution is implemented on the Ericsson IPMM platform, which is identical for all of the above-mentioned technologies, providing operators with a complete access-technology-transparent IP multimedia subsystem.

Ericsson's undisputed world-class competence with air-interface technologies and optimized wireless data-compression has resulted in the Ericsson Instant Talk solution with top call setup performance for GSM/GPRS, EDGE, CDMA2000 and WCDMA networks. The Ericsson Instant Talk solution will be commercially available during the second half of 2003.

"With a minimal investment, Ericsson Instant Talk offers a highly attractive IP-based voice application that complements the wireless operators' traditional voice offering," says Per-Arne Sandstrom, COO of Ericsson. "The service has already proven itself in the market, showing some of the highest user revenues in the industry. Based on Ericsson's access technology-independent solution, Ericsson Instant Talk will allow for full interoperability across different network and handset technologies and help increase operators' revenues."

The Ericsson Instant Talk solution will be compliant to the IMS based push-to-talk standard, allowing operators to offer a large variety of interoperable handsets.

Ericsson's IPMM subsystem provides operators with the ability to leverage their initial investment for push-to-talk services and gradually expand their IP network as new multimedia services are introduced to subscribers. Ericsson Instant Talk is the first in a multitude of services that will be launched on the Ericsson IPMM subsystem. Other services are instant messaging, audio conferencing, interactive session forwarding and video telephony.

Ericsson is a leader in standards bodies such as the Third Generation Partnership Project (3GPP), the Third Generation Partnership Project 2 (3GPP2), the International Telecommunications Union (ITU), Telecommunications Industry Association (TIA) and the European Telecommunications Standards Institute (ETSI). Ericsson is driving global, open standards in order to generate worldwide traffic and revenue for operators and ensure a smooth, seamless experience for consumers.
