The conceptual framework of the digital campus indicates that the construction mode of multi-participation and open sharing and the development mode of fragmentation, rapid iteration, and collective evolution will become the mainstream modes in the stage of digital campus. The advanced technology applied in Chinese campus informatization was analyzed, the main characteristics of the digital campus were put forward, and a conceptual framework of digital campus in universities was designed. Then, the present study used the one-stop service platform of Southwest University as a case study. The practical results of the digital campus included IC (intelligent card) card services, integration services, one-stop services, wireless networks, and the implementation of the data center. The construction of a "one-stop" service platform has become the main method of reform for the digital campus.
