Heavy Reading - With the implementation of voice over LTE (VoLTE) and rich media communication services tipped to be a matter of when and not if for most large tier 1 operators, an Ericsson co-sponsored white paper by Heavy Reading takes a closer look at what those operators need to be thinking about.

Describing VoLTE (GSMA 1R92 VoLTE) as possibly one of the ultimate applications of 4G-LTE networks, the paper looks at its potential game-changing impact on operator business models; the technical and commercial challenges involved; advanced features such as quality of service and extensions into video calling and Rich Communication Suite services.
