Overview of Ericsson’s Voice over LTE solutions

What is Voice-over-LTE (VoLTE)?

VoLTE is a starting point for the evolution of communication services. It is the mainstream technology for IP-based communication services. With the advent of LTE, operators are introducing a broadband only technology, enabling a high-definition voice and video communication experience across a multitude of endpoints and devices. VoLTE solution is designed and fully optimized for automated cloud deployment and agnostic to the underlying infrastructure for both media and control plane, and includes critical automation to simplify creation and maintenance of end user services. VoLTE also support voice for IoT using Cat-M1. Now and throughout the introduction of 5G, telephony services will be addressed by IMS-based VoLTE services.

The Ericsson VoLTE solution encompasses all of the communication core network components and professional services necessary to provide VoLTE communication services such as HD Voice, HD+ Voice, IP Messaging, and IP Video Communication.

Using feedback from device partners, the Ericsson VoLTE solution is architected and designed to serve today’s market where subscriptions are no longer simply one user with one device and one phone number. Read the solution brief and get inspired by different use cases.
