Ericsson has demonstrated 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, and will enable network operators to deploy "walkie-talkie" style communications. 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 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."
