Collaboration illustrates flexibility of FreeWay to support both voice and data bearer mobility on future devices based on Symbian OS

LONDON, United Kingdom - 21 October 2008 - Cicero Networks, a leading provider of rich communications solutions for fixed mobile convergence and Symbian Limited, the market-leader in open operating systems for mobile phones, today announced a proof-of-concept for voice mobility across multiple networks on FreeWay - Symbian's IP communications architecture on Symbian OS™.

Cicero, an active member of the Symbian Partner Network, and Symbian have collaborated to enable Voice Call Continuity (VCC) using the FreeWay communications architecture and CiceroVCC engine. The solution provides seamless in-call handover to enable roaming between circuit switched networks and all-IP based IP Multimedia Subsystem (IMS) networks including Long Term Evolution (LTE) and WiMAX.

As users move through mobile networks today, calls move seamlessly between cells and the user is unaware that this is happening. As all-IP networks are deployed in the future, mobile phones will need to move seamlessly not only between cells but also between network technologies, and VCC is the technology that will allow them to do this. With VCC, users will remain unaware of network switching during phone calls allowing operators to deploy all-IP networks in a staged manner, by having calls switch seamlessly between all-IP networks and traditional circuit switched (CS) networks.

"As mobile service providers deploy next generation IP-based voice networks, being able to support the old and new is critical", said Jonathan Webb, Principal Product Manager, Symbian "Our collaboration with Cicero demonstrates FreeWay's flexibility in enabling voice mobility across multiple network technologies. This is an important step in future network service delivery development." "The combination of Symbian FreeWay and CiceroVCC provides handset manufacturers with an easy route to making Symbian mobile phones VCC compliant," said Ross Brennan, CEO Cicero Networks. "Cicero recognises that native voice bearer mobility is a critical requirement for future service delivery."

Designed to enhance the FreeWay communications architecture, this proof-of-concept highlights both the flexibility and performance capability of Symbian FreeWay for bearer mobility services.

Voice Call Continuity on Symbian FreeWay is to be demonstrated at the Symbian stand (#32) at the Smartphone Show in Earls Court, London on 21-22 October, 2008 - www.smartphoneshow.com.
