Cdma Wireless Access Module Software Design And Implementation

Software of CDMA wireless access module is studied mainly in this paper, the design of main service functions include speech , short message and authentication etc are finished on the foundation of its software running platform—REX embedded operation system and its superstatum application software platform — Binary Runtime Enviroment for Wireless, at the same time the functions of call , sending and receiving short message and authentication function in order to prevent that identification of the terminal equipment used the module as core is preculated are realized.In allusion to the fault of bad transplantable capability, much coding modify, maintenance difficultily, inadaptable to the development of new data service , higher developing cost, uneasily popularize etc, this paper give the software design scheme of platform, based on it this paper propose the design idea of new finite state machine, solve upwards problem efficiently, reduce the cost of module greatly, enhance technology level of terminal equipment and curtail the distance with the kindred product in board.The software design scheme has been applied to fixed station , car-station , wireless access box etc CDMA wireless access terminal equipment and has acquired good effect of application.
