PCTEL and BridgePort Networks Demonstrate Seamless IMS Voice Call Handover Between GSM and Wi-Fi Networks at 3GSM World Congress

Business Wire, Feb 13, 2006

BARCELONA, Spain -- Companies participating in first interoperable implementation of 3GPP's IMS Voice Call Continuity technical requirements

PCTEL, Inc. (NASDAQ:PCTI), a leader in wireless broadband solutions, and BridgePort Networks, the leader in MobileVoIP convergence, today announced the first demonstration of seamless IP Multimedia Subsystem (IMS) voice call handover between GSM and Wi-Fi Networks. The demonstration is taking place at the 3GSM World Congress in Barcelona, Spain (February 13-16).

The demonstration highlights the new voice call continuity capabilities of PCTEL's Roaming Client-VE (Voice Enabled) software and BridgePort Networks' NomadicONE IMS convergence server (ICS) product. The Roaming Client-VE software provides the same user experience and capabilities independent of handset platform and supports both Pocket PC 2003 and Windows Mobile 5.0.

With the PCTEL Roaming Client-VE, users can make and receive calls, on Wi-Fi or cellular networks, through a single user interface on their mobile device. Combined with Voice Call Continuity (VCC) capabilities, users can move from Wi-Fi to cellular coverage and vice-versa without dropping the call. The calls are seamlessly handed over based on the best network connectivity available to the device and/or user preference.

BridgePort Networks' NomadicONE ICS IMS-based fixed/mobile convergence solution provides mobile operators, fixed operators, cable operators and MVNOs the ability to offer single phone number voice services that can seamlessly hand over in-process voice calls between circuit-switched cellular and Voice over Wi-Fi access networks.

The respective solutions conform to technical requirements defined by the standards bodies 3GPP and 3GPP2 for IMS to circuit switched seamless voice handover, known as Voice Call Continuity (VCC). Specifically the solution demonstrated at the 3GSM World Congress implements the IMS Controlled Model (ICM) defined by 3GPP.

"Voice is currently the primary application in fixed-mobile convergence," said Biju Nair, vice president and general manager of PCTEL's Mobility Solutions Group. "As such, integrated solutions that address the portability of voice calls in converged networks are paramount and Bridgeport Networks is an established leader in this space. We look forward to demonstrating how the respective capabilities of PCTEL's Roaming Client-VE and our technology partners are meeting this requirement in Barcelona."

"PCTEL has been a valued partner in the development of the first interoperable implementation of 3GPP's IMS based Voice Call Continuity approach to seamless handover," said Sanjay Jhawar, senior vice president of marketing and business development at BridgePort Networks. "We look forward to working together with PCTEL not only in service provider market trials, but also together within the MobileIGNITE industry association on the seamless handover interoperability initiative underway there."

Attendees of the 3GSM World Congress are invited to visit PCTEL's stand G24 in Hall 2 or BridgePort Networks stand D49 in Hall 1.
