Background To improve network quality of service, operators typically adjust network resource allocation policies based on the importance of the customer (e.g., key customers, businesses, or scenarios). A Network data analysis Function (Network DATA ANALYTICS Function, NWDAF) is used to identify and secure these key clients and the important services they use. Such as for high value users (e.g., global drill-through users), are particularly concerned with their video and live viewing experience to ensure quality of service. For various video services, there are a plurality of different definition gears such as standard definition, high definition, super definition, blue light and the like, and the bandwidth required by each definition gear is different.
