LONDON – Mobile communications company Qualcomm Inc. 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, which takes place Feb. 27 to March 1, 2012.
SRVCC follows on from the launch of circuit-switched fallback (CSFB) technology on smartphones in 2011.
