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.

SRVCC implements a handover function that enables LTE voice call continuity in 2G/3G networks without any perceivable interruptions for the end user. This allows Mobile Virtual Network Operators (MVNOs) that use Scartel’s LTE network to support voice calls.

Huawei provides an end-to-end network solution for Scartel that covers the radio access network, Circuit Switch (CS) core network, IP Multimedia Subsystem (IMS), Evolved Packet Core (EPC), and Huawei’s Ascend P1 smartphone.

According to Infonetics Research, 12 commercial networks with the ability to support 8 million subscribers using VoLTE are expected to be deployed worldwide by the end of 2013.
