Huawei successfully completed an interoperability test (IOT) for an Ultra-Flash Circuit-switched fallback (CSFB) solution with Huawei infrastructure and Qualcomm Technologies, Inc. chipsets at Huawei’s Shanghai R&D facility.

Japan's SoftBank Mobile has selected Ericsson to provide and integrate its end-to-end network solution for voice over LTE (VoLTE). With VoLTE as a basis, consumers will get HD voice and video calling alongside other telephony services, while using simultaneous LTE data services on LTE smartphones.

Russian mobile service provider Scartel has implemented VoLTE (voice over LTE) with SRVCC (Single Radio Voice Call Continuity) using Huawei's solution. Following implementation of the solution, Scartel is now technologically capable of supporting voice calls on its LTE network.

Huawei has completed end-to-end VoLTE voice call with eSRVCC (Enhanced Single Radio Voice Call Continuity, defined in 3GPP R10) handover without any perceivable interruption for the end user, company announced.

Ericsson together with Qualcomm successfully performed a voice handover based on the 3GPP-standardized functionality Single Radio Voice Call Continuity (SRVCC) demonstrating users will experience seamless voice services when they move out of LTE coverage, since the call will automatically be handed over to WCDMA or GSM access during the call.
