[Abstract]:With the development of mobile Internet and its applications, the types of mobile messaging applications are diverse. Because the technology of sending messages from client to server is very mature, the core problem that mobile messaging applications need to face is the downlink message from server to client, that is, how to implement "message push". Message push can greatly improve user activity, so message push has gradually become the standard for all mobile Internet applications. In this paper, the problem of pushing messages from server to Android mobile phone client is studied, and push is used as a service for other applications. After extensive investigation, this paper chooses XMPP protocol as the protocol to push messages from the server to the client. On the one hand, push server provides push message service to third party application through REST interface; on the other hand, it maintains XMPP persistent connection with Android client and pushes message. This paper focuses on solving the key technical problems such as message push protocol design, server supporting a large number of mobile phone users online for a long time, the client and the server to maintain a persistent network connection, and so on. In this paper, the XMPP protocol and the existing message push system architecture are investigated, and the mobile messaging application architecture based on XMPP protocol is designed. Then this paper analyzes in detail how to extend the XMPP protocol to achieve reliable message push. Then, this paper focuses on the design and implementation of push server, including database, REST interface and push module design and implementation. Then the design and implementation of the client are described, including user interface subsystem and communication subsystem. The user interface subsystem is responsible for providing user interface, allowing users to manage push messages, and the communication subsystem maintains connection to the server through the service running in the background long time. Finally, the power consumption, flow consumption, stability and performance of the system are tested by real computer, which proves the effectiveness of the system.
