Calling it a milestone in the development of voice-over-LTE (VoLTE), Qualcomm and Ericsson have completed the first voice call handover from an LTE mobile network to a WCDMA network using single radio voice call continuity (SRVCC). Required for VoLTE support, SRVCC is a 3GPP feature enabling continuity of service by seamlessly switching to a WCDMA network when a VoLTE call leaves the LTE network’s coverage area. The milestone occurred on December 23, 2011 with an Ericsson network using a handset using Qualcomm’s Snapdragon S4 MSM8960 3G/LTE multimode processor. A demonstration will be available at Qualcomm’s booth at Mobile World Congress in Barcelona, Spain, February 27 to March 1, 2012.
