Design And Realization Of Network Accounting System Based On VoIP

With the rapid development of computer technology, modern networkcommunication technology, Internet and IP technology matures, Based on the SIP VoIPtechnology has been widely used throughout the world. SIP (Session Initiation Protocol)is one of the call signaling control protocols on the application layer. SIP not complexhuge system, can only provide the initial session related agreement procedures.In thecurrent VoIP has widespread application in the system. At present, the technologies ofVoIP system become mature, as one of the important supporting systems in VoIPoperation, it is important that the position and significance of VoIP billing systemfunction.VoIP (Voice over IP) or IP phone, is the use of IP Internet phone, voice, video andother digital transmit data through the network, realize the modern networkcommunication technology of instant interactive communication. Specifically, VoIP isthe analog voice signal through a series of compression, packaging and other specialtreatment, to digital, then uses IP packet switching network, the transmission protocolusing UDP technology. Notable feature of VoIP is the ability to use Internet network andglobal IP interconnection, can with extremely low price supply more efficienttransmission of voice, fax, video and data service for users.Based on the study and summarize the basic VoIP voice communication principle,system structure, analysis of the VoIP billing system and function demand, database anduser function module according to the standard of H.323briefly billing system, designmethod and by means of object oriented, using Linux under the Java programminglanguage, billing functions of the system detailed design and development. This systemrealizes the collection, storage and billing functions, registration, and provide a userquery, and user management, information management, data management and otherrelated functions. The test proves the feasibility of the system design and operation. Atthe same time also shows that, this system completes the task demand.
