Bulgaria's leading operator Vivacom is extending its contract with Ericsson to deploy 4G Voice service and Wi-Fi calling.
With the pre-integrated Fast VoLTE Launch solution, the service’s deployment time has been significantly reduced. The agreement builds on Vivacom’s existing Ericsson Evolved Packet Core network and adds virtual IP Multimedia Subsystem (vIMS).
According to the latest Ericsson Mobility Report, VoLTE subscriptions are expected to grow exponentially worldwide and reach 5.4 Billion during 2023.
Vivacom’s customers will benefit from high-quality, simultaneous communication and data services on their devices. The VoLTE solution opens up further possibilities to enable HD voice+ and music within calls, video communication and IP messaging.
The Fast VoLTE Launch solution, a complete pre-integrated virtual IP Multimedia Subsystem (IMS), includes network functions such as virtual Multimedia Telephony Application Server (vMTAS), virtual Session Border Controller (vSBC), virtual Call Session Control Function(vCSCF), virtual Message Resource Function (vMRF) and virtual IPWorks. The solution also includes NFV infrastructure with Ericsson BSP 8100 telecom-grade hardware and the OpenStack-based virtual infrastructure manager, Ericsson Cloud Execution Environment.
