Nortel and Qualcomm Test IMS-based Voice Call Continuity

Nortel and Qualcomm have completed testing between Nortel's IMS-based Voice Call Continuity (VCC) network solution and the Qualcomm chipset solution that uses their IMS/VCC device client. The testing is a major step towards the availability of out-of-the box VCC-enabled mobile phones. As an IMS-based application, VCC moves beyond traditional cellular solutions by enabling service providers to offer innovative multimedia services on mobile phones like network-based real-time, multi-player gaming, enterprise service integration and interactive blogging.

Test sessions were conducted with a Qualcomm test handset using live cellular coverage, rather than a simulation. Testing included authentication, calls on cellular/WiFi, in-call handover using manual and automatic triggers and a variety of error cases. Both Nortel and Qualcomm have implemented the VCC standards defined by the Third Generation Partnership Project (3GPP)**, the global standard for 3G mobile phone systems.

Testing was conducted using Qualcomm's IMS/VCC device client solution on a Mobile Station Modem (MSM) chipset powering a test handset together with Nortel's IMS VCC network solution in Nortel's Ottawa research and development labs. The Nortel VCC network solution is expected to be commercially available from Nortel in the first quarter of 2008. VCC-ready devices are expected to be available from Qualcomm in the market mid 2008.

The companies said a pre-validated IMS/VCC solution allows dual-mode mobile phones to be VCC-ready upon purchase without any additional software downloads or service provider configuration, which is expected to help accelerate broader use of the technology.

"Because Nortel's VCC is based on IMS, it will allow operators to deploy more multimedia services compared to other FMC solutions," said Alf Decardenas, general manager, Carrier Multimedia Networks, Nortel. "Also, Nortel's VCC solution supports seamless voice calling across a wide range of next-generation technologies, as well as Femto cellular access points that are able to connect to the network using residential DSL or cable broadband connections. Nortel is a leading contributor to VCC standards and our successful completion of testing with Qualcomm illustrates that we are committed to deploying commercial VCC solutions in the market, making them available to service providers within their current networks or as they evolve to 4G solutions such as WiMAX, UMB and LTE."
