In the construction of information construction of mobile police, there are problems such as high threshold, long development cycle, low application download, complex business process, weak security supervision and so on. An integrated mobile police management and control platform was built by using big data, cloud computing, mobile internet technology, space information technology and wireless communications technology. In order to solve the problem of information exchange in the police network, the design ideas were put forward that of the platform architecture and network access. the whole life cycle process was discussed that of mobile police service development and application based on APP application store model. The "cloud + end" integration of mobile police terminal security management and control functions and strategies were proposed, and a unified mobile police access and security management standards and norms were developed. The police big data cloud computing platform and the "1+N" service platform which based on elasticity was established, to enhance the ability of police resources docking and police mobile application depth, to improve the efficiency of the mobile business for the purpose of law enforcement.
