Ericsson’s Voice over LTE solutions

Ericsson’s voice over LTE solution

VoLTE (voice over LTE) is the starting point for the evolution of voice and communication services for packet switched networks; LTE, Wi-Fi and 5G (defined by the GSMA specification IR. 92). It is the mainstream mobile network technology for enabling globally interoperable IP-based voice and communication services, using IP Multimedia Subsystem (IMS). With LTE, operators are introducing a mobile broadband only technology, where VoLTE enables a high-definition voice service experience across a multitude of devices and end-points. VoLTE also supports voice for IoT using Cat-M1. 5G voice and communication services will also utilize IMS.

The Ericsson VoLTE solution encompasses all of the communication core network components and professional deployment and tuning services necessary to provide communication services such as HD voice, HD+ voice, IP messaging, and flexible multi-device and multi-line services. It enables consumer voice services, but also builds a foundation for deploying high-quality mobile voice and communication services for businesses, enterprises and industries. The cloud-based VoLTE solutions are designed and fully optimized for automated cloud deployment and agnostic to the underlying infrastructure for both media and control plane, and include critical automation to simplify creation and maintenance of end user services.
