Voice is finally moving to IP with VoLTE: mobile operators views



VoLTE is not just about costs and spectral efficiency. It enables operators to provide the better voice quality and lower latency that are the key requirements of GSMA’s rich communication services (RCS), and that will enable them to support the chat, voice, and video applications envisaged by the recently launched joyn project. In this context, VoLTE is a necessary complement to video services and applications that have started to dominate the traffic load and that promise to generate an increasing portion of revenues.

Today most operators find these services challenging to provide, as they cannot consistently guarantee a specific level of performance even to high‐paying subscribers. VoLTE, coupled with QoS, traffic prioritization, and policy, will enable operators to roll out the adaptive multi‐rate wideband (AMR‐WB) codec needed for high‐definition (HD) voice, differentiate the services they offer across subscriber segments (high‐paying, high‐performance subscribers versus best‐efforts, lower‐ARPU subscribers), and from the services offered by their competitors. The increased variety and richness of voice services that VoLTE will allow drives the expectation shared by 50% of operators that, despite the worries of competition from OTT players like Skype or Viber and despite the elusiveness of their monetization efforts, VoLTE will lead to higher revenues and better subscriber experience.
