Abstract


Softswitch (SoftSwitch) to provide phase separation of the call control function and a media processing devices and systems based on the sub-network using programmable software. With the continuous development of large soft-switched networks, the the softswitch network equipment health degree become the focus of increasing attention. More reasonable way is through the application layer softswitch managed to achieve the maintenance of the entire switch. Various manufacturers of the products, however, is complicated, the design concept is also very different in the inside of the device, the module division reflect the vastly different. Even different versions of the same manufacturer's equipment are quite different, and how to find out in the increasingly rapid and complex network evolution maintenance mode to ease upgrading equipment to maintain the impact of this project. As the carrier's maintenance unit, softswitch equipment maintenance is a question worth considering whether it is equipment hardware to a machine frame rack as small as an office card chip memory, or operating system processes, procedures, in maintenance scope. The basis for maintenance personnel is much higher than the proportion of engineers and an inexperienced maintenance personnel how to make sense, one can have a good judgment of the ability of the device operation is also presented in this subject. The subject from the actual needs, proposed the establishment of mobile softswitch end office equipment health assessment needs to develop a more complete assessment of the standard softswitch equipment, easily and accurately reflect the state of the operation of equipment. This paper first introduces the basic knowledge of the soft-switched networks, research and analysis, and then for the the softswitch network equipment in the existing network running on the the softswitch network health assessment criteria and methods for comparative analysis and test data comparing on specific manufacturers equipment for pilot testing and test development, put forward a well-established, and has entered the commissioning assessment software platform design and development of ideas. At the same time, this article from the exchange network principle, the signaling protocol introduced major softswitch network health criteria and algorithms introduced, as well as a discussion of methods of analysis of the different health assessment, a detailed study softswitch network health degree some of the standards and practices in the company's application method, design, and proposed for the development of the field of mobile communications use, better scalability, and extensive use of the value of software tools platform, described the purpose of design, system architecture, platform networking, and to expand the functionality of the software tools and systems The test carried out a detailed introduction and detailed accounting. Finally, on the subject of the thesis put forward a new outlook and a conclusion and summary of the thesis and the results achieved. Vision for new arguments and new methods proposed in this study, and will in the future depth study and research.
