For the mobile Internet, the business model of telecom operators has to evolve to Teleco2.0. IP Multimedia Subsystem (IMS) will be used mainly for VIP and enterprise customers. Mass-oriented entertainment and new media services will be based on the Intelligent Node Overlay Node (INON)/Distributed Service Network (DSN). The core network will be flat, with an evolution route from Internet High Speed Packet Access (I-HSPA) to System Architecture Evolution (SAE), and even the Internet can be used as the core network. The low-cost mobile phone can be accessed to HTTP Internet by using 'client end software + portal'model with cloud computing. Flat rate will be the only fee model to be accepted by customers, and cheap and reasonable prices will contribute to the development of mobile Internet.展开更多
