In order to solve the existing problems on tourism information system, a new tourism information system with B/S and C/S architecture is present. [Method] The system adopted B/S and C/S mixed architecture based on Android and web platform to ensure stable and secure operation of system. SIP protocol, RTP protocol and JNI technology were applied for system implementation. [Results] The whole system platform consists of three layers: the upper layer uses the B/S architecture to implement the travel information Web; the middle layer realizes the sharing of the upper and lower information resources by the shared database; the lower layer adopts C/S architecture to acquire the tourist information through the user APP based on Android platform; and B/S and C/S interact with each other in the mixed structure. Furthermore, the SIP protocol and RTP protocol JNI technology improved poor adaptability of the WEB interface for mobile terminal, simple expression and lack of scenic spot and traffic evaluation. [Conclusions] The present system has a lot of advantages of both B/S and C/S architecture and will be of great value for large-scale information systems development.
