Ericsson conducts voice handover with Qualcomm

Ericsson and Qualcomm have jointly performed a successful voice handover based on the 3GPP-standardized functionality Single Radio Voice Call Continuity (SRVCC).

With this the users will experience seamless voice services when they move out of LTE coverage, since the call will automatically switch to WCDMA or GSM access during the call.

The handover of a voice call from LTE to WCDMA was successfully established on December 23 last year, using Ericsson's network infrastructure, and an LTE/3G multimode smartphone chipset from Qualcomm.

''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,'' said Johan Wibergh, head of business unit networks, Ericsson.

SRVCC enables operators to deploy voice over LTE, to provide a robust voice service with global reach to their LTE smartphone users.

The handover mechanism is supported on Ericsson's products and solutions including- LTE/WCDMA/GSM RAN, Evolved Packet Core, MSC and IMS to work towards VoLTE enabled LTE smartphones.
