Greetings from Mobile World Congress in Barcelona. During the OMA Demo Day this Wednesday, Interop will be one of ten OMA member companies to be showcasing solutions that rely on OMA enablers to develop interoperable mobile services.Our RCS solution uses specifications facilitated by OMA to provide features such as one-to-one and group messaging as well as interworking between RCS and legacy messaging services. It also uses OMA specs for its XML document management server (XDMS) and presence server to store and display service capability information and social presence data, such as contacts’ availability and location, in real time to RCS users. Compliance with OMA specifications is critical to ensure the interoperability of RCS as this technology evolves.
