Design And Implementation Of Application Layer Software Of BTS Main Control Board

With the progress of our economy, society and science, we have already come into the information age. As a new generation communication system, the Code Division Multiple Access technology is developed very fast, and become the first choice of the third generation mobile communication system. CDMA radio communication system is a kind of advanced personnel mobile communication system and is a radio directed communication system, which has larger capacity, wider coverage area and better voice quality than GSM which is a kind of traditional radio communication system. Based on the privated study of the CDMA mobile communication system of Beijing capitel limit company, this paper is especially on the design and implementation of BTS Main Control Unit application layer's software.First of all, this paper summaried the development of the communication system, simply introduced the structure and interface protocol of the cdma2000 lx mobile communcicaiton system, designed and validated the calling control flow based on the interface protocol.This paper analyzes stressedly the design and implementation of the Main Control Board application layer's software.The main function of the software is call control and resource management. Based on the required function,the software divided into several sub function module. In this paper, we detailed introduced the realization of the sub-module,and some important scheme. This project using C and C++ general programming language based on VxWorks to complet the designing work of the cdma2000 lx mobile communication system BTS main control board application layer's software. Acturalized the process function of voice and data signaling.At last we get the testing result of the base station which shows that the software meets the design requires.
