Next Step for VoLTE is Interoperability Between Operators, says 4G Americas

4G Americas, a wireless industry trade association representing the 3GPP family of technologies, including LTE and LTE-Advanced, has published the white paper, VoLTE and RCS Technology Evolution & Ecosystem, which describes in detail the recommendations and best practices for Voice over LTE (VoLTE) and Rich Communications Service (RCS) implementations and offerings. VoLTE supports higher quality calls and faster call connections, and in combination with RCS, provides new features in three major service areas: telephony, messaging and contact management.

4G America said that VoLTE is a business solution that provides operators with a complete solution to evolve their voice business towards an all-IP communications network. This is achieved by evolving the installed base circuit switched core network towards an IP Multimedia Subsystem (IMS) core network, which supports communication services like High Definition (HD) voice, video calling, Wi-Fi calling and RCS services, added 4G Americas.

4G Americas highlighted that a key element in the next step of evolution for VoLTE will be interoperability between operators, citing AT&T and Verizon's VoLTE interoperability testing and readiness to launch the service in 2015. Similar to VoLTE, RCS takes advantage of IMS control capabilities encompassing a rich multimedia service portfolio, including multimedia messaging, chat, file transfer, privacy, buddy lists and presence.  Overall, VoLTE combined with RCS provides a platform for an enhanced integrated communications experience for subscribers, said 4G Americas.

4G Americas President Chris Pearson
VoLTE is progressing in North America and other parts of the world as operators’ coverage footprint of LTE is expanding. As VoLTE combined with RCS unfolds, carriers are able to offer new and simple-to-use communications services that customers will appreciate.
