Qualcomm, Ericsson perform successful VoIP-over-LTE handover

Qualcomm and Ericsson completed the first voice call handover from an LTE mobile network to a WCDMA network using Single Radio Voice Call Continuity (SRVCC), the companies announced today.

SRVCC is a 3GPP specified feature that enables continuity of service by seamlessly switching to a WCDMA network when a consumer on a VoLTE call leaves the LTE network's coverage area; it's a technology required for voice-over-LTE (VoLTE) support.

The call was completed with an Ericsson network using a handset that incorporated Qualcomm's Snapdragon S4 MSM8960 3G/LTE multimode processor. Qualcomm is demonstrating the technology at its booth at Mobile World Congress in Barcelona, Spain later this month.
