Design And Implementation Of IOS Enterprise Mobile Communication System

Today, Internet technology is widely used in different profession, and the information technology has a great development. Various trades and industries require more stringent efficiency. In business, communication and communication efficiency improvements to reduce costs, representing the work efficiency, and therefore the deployment of real-time communication system is particularly important in the enterprise. The traditional personal communications software contains a large number of commercial and entertainment information. If ordinary personal instant messaging software in the enterprise, these commercials and entertainment will distract the attention of the staff, reduce employee productivity, and therefore in enterprise instant messaging system should be completely abandoned these work-related content and thus greatly improve the efficiency of the company's employees.Enterprise Mobile Communication System developed based on C/S structure,according to the investigation and research of instant messaging system background, we noticed the necessity and convenience of instant messaging system. First, I introduced the basic knowledge of i OS development, and describe XMPP protocol concepts and principle of XMPP operation. Then present the principle and application architecture of instant messaging system. After that we do a system requirements analysis,according to the system requirements, we have a detail design for the enterprise mobile communication system client and server. The server system based a open source server named Openfire for secondary development, made the server a further expansion based on the original structure. The client system based on the most popular mobile phone operation system-i OS, the client system adopted the model-view-controller(MVC) design model, the model will be the application of each functional component separation, so that the code maintenance and extension. According to the design of the system, the client can be divided to seven modules, they are login module, phone module, instant messaging module, department module, conference module, search module and system setting module. Then we based on the system's requirements and design, we implement the enterprise mobile communication. Finally according to the realization of the system, we test the system.Using enterprise mobile communication, communicate efficiency has a greatly improving, users can timely to send and receive chat messages, when using the system call function can also be very good guarantee the quality of calls. After testing the system is stable, can satisfy the need of users, and achieved the desired goal.
