The Design And Implementation Of The Instant Messaging Communication System Terminal

With the rapid development of mobile Internet,instant messaging(IM)becomes more and more important on mobile device.Although the IM system provides people with MSN,WeChat,QQ and other applications,provides a good communication platform,because the system itself follows a variety of protocols,resulting in the lack of scalability and connectivity.XMPP agreement with its own advantages,just to solve this problem,and promote the rapid development of instant messaging.Aiming at this situation,this thesis use the XMPP protocol,Android development platform to presents the instant messaging system terminal design.Respectively,it provides a method for the application of instant messaging,and discusses the corresponding function to achieve.According to the Android development platform,XMPP protocol advantages and architecture,respectively,we detailed design for the system's server,Android client.Then from the registration function module,the user login function module,the friend Management function module,the friend list display function module,the conference management function module,the instant messaging function module,data storage function module,encryption and decryption function module,and the document transmission function module to discuss the realization of the server function or the implementation of the client function.Respectively,the instant messaging system terminal function modules for the preparation and testing of the code.Through the construction of the instant messaging system terminal design,it has deepened the understanding of its operation process,and provides a reference for the study of instant communication.
