The Design And Implementation Of An IOS-based Enterprise IM System

With the rapid development of mobile Internet, mobile communication bandwidth rate increase more and more, the mobile Internet users are no longer meet with the text, image transmission and other communication functions from the traditional simple mob ile IM system. It is urgent to design and implement a mobile IM system real accord with the features of the mobile Internet to meet with the growing demand of high quality net work communication services. In order to fully grasp the development of China Mobile IM system technology trends, judge the mobile application market, layout of the mobile application market, grasp the accumulation of social system of Internet users habits such as the use of valuable information, these features needed to be done.According to the different needs of mobile Internet users and enterprise users, base d on the overall planning of mobile project management department, this project are dec ided. In this paper, the necessity of design and implementation of the communication m odule and the network value-added service module in a mobile IM system are fully dem onstrated. At the same time, the system functional requirements and non functional requ irements are analyzed, the overall technical scheme, the system architecture, function m odule, internal and external interface, database technology and other aspects are overall designed. In the implementation process, the system makes full use of the software engi neering idea and object-oriented programming idea, and makes flexible use of the matur e software development framework, to ensure that the final system is easy to maintain, e asy to expand.The results of this study eventually transformed to design and implement the com munication module and the network value-added service module based on IM system. I n this project, multi terminal online at the same time, unified message center, discussio n groups, VOIP.Enterprise security certification,contacts management, enterprise management. The demand of ordinary users and enterprise users for basic communicati on services and Internet value-added service are met well.In this project, My mainly responsibility is analysis the problems left over from the existing IM systems, market research for new demands, and finally assumed the basic needs of the IM communication module system of value-added services and enterprise-level platform module analysis, outline design, coding and so on.
