Q: Will technology such as the IMS based Joyn be able to compete with OTT voice players?
Dr. Choi, Jin-sung, is senior vice president and head of technology strategy office for SK Telecom, Korea: OTT service only enables communication between customers who downloaded the application, whereas RCS services like Joyn allows users to call/chat with and send multimedia contents to any number stored in the phone address book. RCS services’ strength lies in the stability, reliability and security guaranteed by telecommunications companies. Thus, a speedy response focusing on the customer experience will be crucial to differentiate RCS services from OTT services.
Q: Is there enough innovation occurring in the mobile network industry? Can you provide some examples?
Dr. Choi: At present, the mobile industry is witnessing an evolution to 4G LTE, the fastest telecommunications network. High speed networks not only enable fast mobile internet service but also support the advent of more innovative services. For instance, ultra-fast LTE networks will lead to the creation and provision of real-time network games and mobile video streaming services as well as more innovative convergence services like health care and smart learning services.
