Design And Implementation Of The Simulation Of Large Number Calls Based On CDMA2000 1X Channel Plate

With the large-scale commercial of the cdma standard base station, the version of veneer on the base station updated more frequently, how to maintain the stability of the version in this case also become a problem. The original method is to use multiple phone calls to test the stability of the version, Now, commonly used method is to use simulation software to communicate with the board to test the stability of the version. However, This method still has some problems, such as difficult to locate the fault and imperfect process simulation.To solve this problem, by studying standard voice call flow, the method of using the channel plate to simulate large voice calls was proposed. Unlike the previous method of the program, the system is running in the channel plate. the voice call flow of this system is based on the standard process. Using a callhandler process to simulate a call and using a callcontrol process to simulate the whole process. The realization of main modules based on finite state machine, those could make the code more clear and effective. This architecture could provide a useful reference for the future development of related products.Finally, through the functional test and stability test, shows that the system can successfully simulate several phones and test the stability of the veneer. And we also find out some issues that should be improved and analyzed in the future.
