Development Of Software Development Kit For The Client Of Digital Trunk Scheduling System Based On Web Technology

The digital trunk scheduling system is a special command dispatching system with fast access and strong security,it is widely used in various professional departments.Digital trunk users directly contact the digital trunk scheduling system client(handheld terminal and PC),the diversification of digital trunk scheduling system client application scenarios not only requires a flexible digital trunk scheduling system client,but also needs to implemented the function of the scheduling system client on the PC side web page.The software development kit can provide users with a collection of software development tool interfaces to meet the development needs of digital trunk scheduling system clients.Therefore,the development of software development kit for the client of digital trunk scheduling system based on Web technology is of great significance.Based on an overview of the development status of digital trunk scheduling system at home and abroad,this thesis designs and implements a software development kit for the client of digital trunk scheduling system,the main tasks are as follows:1.Based on the system composition of the digital trunk scheduling system,the interaction between the client of the digital trunk scheduling system and the server of the scheduling system is analyzed,and the main functions of the client software development kit are given.2.Based on the signaling process of user,voice,data and scheduling functions of the client software development kit,the interface between the client software development kit and the scheduling server,Web server,and media gateway is designed,and the software development kit and scheduling are clarified Data format for system server interaction.3.A software architecture of the client software development kit is proposed,it consists of interface programs,Node.js services and background voice programs,It is versatile,it provides the external interface of the software development kit and the interface among the software development kit,scheduling server,Web server and media gateway.4.Based on the Windows system,using Java Script and C ++ programming languages,the interface program,Node.js service and background voice program of the digital trunk scheduling system software development kit have been developed to implement user functions,voice functions,data functions and scheduling functions.5.A test environment for the client of the digital trunk scheduling system was built,and the web client was used to call the software development kit to test user functions,voice functions,data functions and scheduling functions.The test results show that the developed software development kit can meet the basic functional requirements of the client.
