Design And Implementation Of Mobile Network Instant Communication Mechanism

Instant communication technology has been widely used in mobile Internet. Thereal-time rich-media communication between users requires relatively reliable real-timecommunication mechanism in the unstable mobile Internet. Currently, there are somewell-recognized instant message applications both abroad and in China. However, theircommunication protocols and related communication technologies are reserved tothemselves only. In this article, we designed and implemented an instant communicationmechanism based on message notification, which meet the actual demand of mobileradio system and made a combination of radio, Wechat and Weibo. This communicationmechanism is based on existing social relationship of Shenyang Radio and TV users,and is utilized for mobile devices which have low power and small memory.Firstly, this paper compared and analyzed the existing push instant communicationprotocols and related technology, including NoSQL databases and network I/Omultiplexing technology etc. Secondly, we introduced interactive mobile radio systembriefly, used ELGG as the social network framework and MQTT as the messagetransport protocol, and achieved an instant communication mechanism architecturebased on message notification. Then we analyzed types and data flow of messages andcommunication mechanism of multimedia messages within this system. Thirdly, weintroduced the WebService interface and plugin design of ELGG, analyzed topic types,organization and message formats based on MQTT protocol principles, detailed thedesign and implementation of presence and multimedia server within communicationprocessing. Finally, we give the performance test data of multimedia server, used mobilephones to test our work, and results proved the feasibility and reliability of ourcommunication mechanism.
