Ericsson and Qualcomm Complete Voice Handover from LTE to WCDMA

Ericsson and Qualcomm announced the successful handover of a voice call from LTE to WCDMA on an end-to-end network. The handover used 3GPP-standardized Single Radio Voice Call Continuity (SRVCC).


The testing, which was completed in December, demonstrated seamless voice service when the user moves out of LTE coverage as the call is automatically handed over to WCDMA or GSM. The end-to-end network was supplied by Ericsson and the smartphone used an LTE/3G multimode chipset from Qualcomm. The handover mechanism is supported on Ericsson's end-to-end products and solutions; LTE/WCDMA/GSM RAN, Evolved Packet Core, MSC and IMS to work towards VoLTE enabled LTE smartphones.


"By accomplishing this advanced LTE handover technology together with Qualcomm, we now ensure that operators can meet consumers' expectations on a high-quality voice over LTE service. Operators will be able to maintain their quality brand for their voice business when they launch voice over LTE," stated Johan Wibergh, Head of Business Unit Networks, Ericsson.


The first operators are expected to begin deploying SRVCC during 2012, followed by more global commercial launches in 2013.
