Mobile Internet will be the killer application of 3G. 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.

Wideband Wireless Mobile Internet (WWMI ) has become one of the most important technologies for Modern Service. The Modern Service information communication multi-access network can easily realize the new operation modes formed by various Modern Service support systems. We think that under the new operation modes, the charges on calling and information will become more negligible, while the charge on services provided by the direct service support of various Modern Service platforms will turn into a major revenue source. It is suggested that the operators build an operation service support platform with common services to cooperate with thousands of information websites, help clients to transform information into profit and carry out operations and services.

This paper proposes that the business model of mobile Internet services is shifting from a walled garden to an open one. The service development model relies more on open Application Programme Interface (API ); and the online application software store is becoming an important platform for service delivery. The terminal platform has been the commanding point of the layout and competition of the mobile Inernet in the world. Based on the smart terminal, the competition for platform system from the hardware platform to the operation system, the middleware and the applications platform have been in shape globally. The competition in the terminal platform of mobile Internet is moving from close to open, from uni-controlled by one company to open and cooperated by the whole industry. China should forge a terminal platform system and the ecosystem for the mobile Internet industry, and seek to achieve an overall breakthrough in the whole value chain of the industry based on the huge mobile user market and the productivity of the terminal. The breakthrough should start from the application software, stepping from the top to the bottom platform, to extend the industry chain.

Packet scheduling algorithm is the key technology to guarantee Quality of Service (QoS ) and balance the fairness between users in broadband Wireless Metropolitan Area Network (WMAN ). Based on the research of Proportional Fairness (PF ) algorithm and Modified Largest Weighted Delay First (M-LWDF ) algorithm, a new packet scheduling algorithm for real-time services in broadband WMAN, called Enhanced M-LWDF (EM-LWDF ), was proposed. The algorithm phases in new information to measure the load of service queues and updates the state parameters in real-time way, which remarkably improves system performance.Simulation results show that comparing with M-LWDF algorithm, the proposed algorithm is advantageous in performances of queuing delay and fairness while guaranteeing system throughput.
