Qualcomm, Ericsson Successfully Test First Ever LTE to WCDMA Voice Handover

Qualcomm announced on a proud note yesterday that the company has successfully carried out the first ever LTE to WCDMA voice call handover.

The project, which was carried out in collaboration with Ericsson, saw the duo using the Single Radio Voice Call Continuity (SRVCC) to accomplish the goal. It's indeed a crucial success not just for Qualcomm and Ericsson, but for the industry as a whole, as the new technology is likely to play a crucial role in voice over LTE (VoLTE) support.

SRVCC happens to be a 3GPP specified feature that allows services to continue without any hassles whatsoever by switching it to an available WCDMA network, meaning even when a user enters into an area with no LTE network coverage, it won't disrupt the service, and thus ensuring much more flexibility.

The test was completed on a successful note on December 23, 2011 and it involved a handset powered by Qualcomm's Snapdragon S4 MSM8960 3G/LTE multimode processor, and an Ericsson network.

"As LTE networks are deployed alongside 3G networks, the ability for multimode 3G/LTE mobile devices to connect to different network technologies will be an important part of providing the best possible mobile voice and data experience to consumers," Cristiano Amon, senior vice president of product management, Qualcomm said in a statement
