Qualcomm, Ericsson demo LTE-to-3G handover

February 03, 2012 // By Peter Clarke
Qualcomm has announced that, working with Ericsson AB, it has completed a voice call handover from an LTE mobile network to a WCDMA network using Single Radio Voice Call Continuity (SRVCC) technology.

SRVCC is a 3GPP specified feature that enables continuity of service by seamlessly switching to a WCDMA network when a consumer on voice-over-LTE call leaves the LTE network's coverage area.

The successful LTE-to-WCMDA transfer occurred on Dec. 23, 2011 using a handset based on Qualcomm's Snapdragon S4 MSM8960 application processor that is 3G/LTE multimode capable. Qualcomm plans to repeat the demonstration at the Mobile World Congress in Barcelona, Spain.

SRVCC follows on from the launch of circuit-switched fallback (CSFB) technology on smartphones in 2011.
