RCS is a technical standard designed by GSMA and built on IMS network with unified business set definition, which is the general name of multimedia services such as instant messaging, voice and status based on mobile phone directory. We can provide a complete end-to-end solution of RCS based on the GSMA specification, including IMS, RCS AS, MaaP, RCS HUB and RCS SDK. RCS can take full advantage of the operator’s network, upgrade the traditional SMS service, provide multimedia messaging capability and a new information service entry point. Meanwhile, GSMA Ng.114 specification defines RCS as a mandatory function of 5G terminals, and RCS is also the core business of 5G messages.
