The invention discloses an intrinsic function identification method based on a subgraph isomorphism matching algorithm in decompilation, and belongs to the technical field of decompilation. By establishing an intrinsic function template library, the present invention performs subgraph isomorphism matching on the intrinsic function template and the target assembly file based on the control flow graph generated by decompilation, and locates the compiled optimized and inline expanded objects in the target assembly file in the target program. intrinsic function. The invention realizes the automatic identification of the inline intrinsic function in the process of decompilation, and at the same time, by analyzing the template and prototype of the intrinsic function, the function name, return value, return value type and function parameters of the intrinsic function are restored, so as to achieve the inline function. Purpose of intrinsic function semantic promotion. The improved inline intrinsic function provides more type information for type analysis in decompilation, reduces the complexity of data flow analysis and control flow analysis, improves the abstraction level of intermediate code, and enhances the reliability of decompilation results. readability.

A model-driven method and system for generating telecommunications convergence services suitable for different interfaces and platform technologies. The system consists of a business model editing / expression tool, a model compiler container, various model compilers residing therein, and corresponding model mapping rules Library, and model storage warehouse, each component realizes information interaction through standard interface. The generation method is: first generate a general business model independent of the specific interface technology and platform technology, and then sequentially carry out the general business model to the specific interface technology-related model, the interface technology-related model to the implementation platform technology-related model, and the implementation platform technology-related model to The specific programming language implements various mappings of the code, and then deploys the executable business logic code to the application server. The invention enhances the portability of business models between different API interface technologies and different implementation platform technologies, improves the ability of business logic to cope with technical changes, and can improve the development speed and efficiency of new telecom services.

The present invention relates to a telecommunication-field modeling tool and a modeling method based on unifying a modeling language, which belong to the field of system software and application software of a computer. A four-layer metadata structure based on unifying a modeling language constructs mechanisms of element modeling and two-stage modeling; the element modeling establishes a domain element model of the telecommunication field, and the modeling establishes a specific applied model in the telecommunication field; a concrete member contacts concrete equipment in the model by a customization function. The equipment is displayed, controlled and managed by the models. The element model comprises domain knowledge and constrains modeling behavior; a model established in a modeling process is ensured to conform to the constraint of the field. Because the equipment is displayed and managed by the customization mode, the abstraction levels of solving problems are improved. Therefore, developers can pay attention to the logic of the problems rather than the details of low-level realization. The efficiency and the correct rate of software development are improved, and developing cycles are shortened. A modeling method of telecommunication field based on unified modeling language includes structuring two-stage of modeling mechanism for elementary modeling and modeling based on structure of unified modeling language of four layer elementary data, using elementary modeling to establish field elementary model and modeling to establish a concrete application model, applying custom - made function to relate a concrete component in model to a concrete equipment and using model to control and supervise equipment.
