Building next generation voice services using VoLTE

VoLTE enables operators to offer high-quality, simultaneous communication and data services on smartphones and on many other devices, across LTE, Wi-Fi and 5G. There are many new types of use cases that can be enabled on your smartphone, and voice quality improvements with HD voice is the first one. But more can be done by operators, and it will get easier to upgrade with new operator based communication services when we are stepping into the world of cloud.

Several operators are already running VoLTE over cloud-based core networks, to support more cost-efficient network operations and faster scaling of capacity. This network evolution builds upon NFV and enables faster launches of new services, which is now starting to happen as new types of VoLTE devices and use cases are emerging on the market.

It has been agreed in 3GPP standardization that VoLTE technology will be the foundation for enabling 5G voice calls. New use cases in a 5G context are being explored, and already now operators can start providing voice for IoT use cases.


VoLTE growing fast across all regions

VoLTE has now been launched in more than 155 networks in over 75 countries across all regions*. With the number of subscriptions expected to reach 5.4 billion by the end of 2023, VoLTE provides a firm ground for operators moving forward. VoLTE creates a foundation for interoperable consumer and enterprise communication services on different devices across LTE, Wi-Fi and 5G.

VoLTE is the foundation for evolving today’s voice service on smartphones, to a much broader range of communication capabilities, download our guide and learn more!
