By studying the characteristics of cloud computing and the way of connecting cloud with mobile terminal equipment, this paper proposes an optimized framework of instant communication in mobile cloud computing environment. Around the framework, we study the data Transmission format optimization technology and how to use Markov model to improve the network switching strategy. Firstly, this paper introduces the design of frame cloud and mobile client. Cloud is divided into several levels, including data cache layer, data storage layer and network switching predictive engine; Mobile client is divided into several modules according to function, mainly includes four modules, such as communication, data conversion, network management and UI interaction. Then, the detailed implementation details of each level and module are introduced. In the realization of data transformation, a data format with faster parsing speed and smaller data volume is used to replace the existing XML or JSON format, and the second-order Markov model is introduced in the realization of the network switching predictive engine, which is protobuf To provide users with network switching strategy, so that users know where more should use the network, so as to save the mobile end of the electricity, flow consumption purposes. Finally, according to the prototype system implemented by the real-time communication framework in mobile cloud computing environment, the energy consumption of data transmission after using frame is given and the energy-saving advantages of the framework are verified by the test of the application example.
