Since 2017, traditional audio ring tone services have gradually entered the end of their life cycle, and the global market space including the Chinese and Korean markets has been declining year by year. From 2017 to 2019, China Mobile and Huawei, EASTCOM-BUPT, ZTE and other platform vendors, as well as Samsung, Qualcomm, OPPO, vivo and other chip and terminal manufacturers, have comprehensively innovated the video ring tone service. At present, the video ring tone has been applied in the Chinese market (including China Mobile, China Unicom, China Telecom), and the cumulative number of users has exceeded 200 million. In addition, other European and Asian countries are also introducing and deploying video ring tone services. However, we also encountered some industry obstacles, including obstacles on UEs, contents, and networks. We need to consider the solution on some key industry obstacles in this work item. The scope of Specifying the technical requirements and extended application scenarios of the Early Media is the primary task of standardization based on which this proposal proposes the application scenarios and requirements of Early Media service.
