H.248 Protocol To Improve The Structure Of The Code

With the bloom of Internet and the development of IP technology and VoIP technology, VoIP products are now having a rising market of the telecommunication, VoIP technology becomes one of the most popular topic in computing and telecommunication field. Because of the good feature such as simpleness, flexibility and extensibility, H.248 becomes one of the most important technologies in VoIP and considered the key technology in the Next Generation Network technology.This papers first introduced the VoIP technology’s key technologies and architecture, and then compare a variety of VoIP signaling protocol, and then introduced the media gateway and the H.248 protocol procedures for the overall structure, this leads to two core contents of papers, The first is to improve the readability and maintainability of the protocol procedure, modify the process of the message sent by the media gateway controller, By making the boundaries of each functional sub-module more clearly, it can bring greater convenience when do some modifications to the news structure. The second is to increase the portability of protocol procedure, merge the part of the operation unrelated to the protocol and formed a new call control module, such changes allows our process can be easily applied on the media gateway with different underlying hardware architecture only need a small number of modifications. Finally, this papers describes the functional testing and stress testing of the H.248 module, and gives the relevant test data.
