Voice over LTE (VoLTE) and a complementary conversational video service specified by GSMA are set to become mainstream technology for IP-based telecommunications, just as voice is an integral part of 2G and 3G networks today.
VoLTE enables high definition (HD) voice quality, helping operators compete against over-the-top (OTT) VoIP providers. In addition, VoLTE offers lower delay and higher capacity compared to OTT VoIP services, which tend to generate a greater load on operator networks and adversely affect service quality.
Similar to VoLTE, Rich Communications Services (RCS) takes advantage of IP Multimedia Subsystem (IMS) control capabilities, encompassing a rich multimedia service portfolio, including multimedia messaging, chat, file transfer, privacy, buddy lists and presence.
This white paper describes in detail the recommendations and best practices for VoLTE and RCS implementations and offerings.
