This thesis describes the design framework of the multi-language translation system for mobile environment, including the overall design of the client / server framework, client-server interaction process design, as well as client and server design details, the use of technology in the process. Client / server mode is the main mode of today's mobile Internet applications, mobile devices with limited resources from the server via wireless access to the Internet, a rich variety of services, Google's cloud computing the Baidu box plans are based on the client / server model , the subject of design thinking for many mobile application development has a guiding role.
