Cloud VoLTE and Evolved Communication

Ericsson Cloud Voice over LTE (VoLTE) provides high quality communication services using all-IP technology over LTE-based mobile broadband.

In addition to customary mobile telephony services, our Cloud VoLTE products support value-added services such as HD voice, HD+ voice (EVS), video calling, Wi-Fi calling, multi-device, multi-SIM, enriched calling services and voice support for IoT devices (Cat-M1).

Our portfolio includes industrialized solutions that can launch VoLTE services to your customers in weeks instead of months, as well as automated acceptance tests to reduce the TTM of new services you develop.


Full device interoperability from end-to-end solution

Ericsson’s Cloud VoLTE and Evolved Communication is a complete end-to-end offering based on GSMA IR.92 and related specifications to provide SMS, voice and video communication services over LTE access. This guarantees full device interoperability and allows for direct IP interconnect and roaming towards other operators.

Cut costs with higher value services

Building on an all-IP infrastructure such as LTE, EPC and IMS allows operators to cut operational cost by improving resource utilization with, for example, improved spectrum efficiency. It also enables operators to reduce customer turnover by introducing higher value services such as HD voice, HD+ voice (EVS), video calling, multi-device, multi-SIM, call enrichment,etc.

No disruption of the user experience

VoLTE users will keep the convenience of the mobile experience, using the built-in phone dialer and call screen with no need for app’s to make calls or messaging over IP. Users can also continue to benefit from a service with global reach. In other words, they can make and receive calls from any phone number in the world and still be reachable while roaming anywhere in the world.
