Research And Implementation Of New Mobile Phone Address Book Server Based On SIP

With continuous development, the mobile communication network has becoming more and more integrated, intelligent and personalized. The boundary between basic telecommunications services and value-added telecommunications business has become more confusing. As the improvement of mobile terminals communication capabilities and the increasing speed of messaging exchanging, people’s desire for diversity and personality of telecommunications business has also been more and more intense. This requires the market to develop more innovative, faster, and better telecommunications services to meet the users’demand. Thus, the research and development of the new generation of public-oriented and completely open applications for mobile devices have become the focus of people’s attention, and also has very important practical significance. So the applications based on mobile phone address book are always one of the most basic service functions.In summary, the current application market of mobile address book requires the function which is based on a flexible, expandable and open protocol stack and also contains all the features of address book in the current application market. The system described in this paper also has some characteristic features such as synchronize and backup contacts, send and receive instant message, SNS function and off-line mode. With this kind of market demand, this paper designs and studies a new mobile address book based on SIP, implements the system server, and has important research value and practical significance.This paper proposes the server framework model of a new SIP-based mobile phone address book system, the system can be easily set up to achieve real-time information exchange, support concurrent access of a certain amount of data, has quick response, and also support different kinds of clients to access and provide a full range of software features for client users. This paper describes the SIP and related open source protocol stack and development libraries, implements a new SIP-based mobile phone address book system server based on these libraries. The system includes SIP server, application server, Web server and address book database.The system’s functions contain contact management,synchronization and backup, instant messaging, black and white lists, SNS functions, and also include a range of value-added service. Finally, build a test system, which work with the phone contacts client and SIPp tool together to achieve pressure testing, performance testing and functionality testing of the entire system, through the analysis and comparison of experimental data,this paper verifies the reliability,feasibility of the system, and raises up some revision opinions.
