Abstract

The current diagnostic monitoring(DM) systems of cellular phones have many problems since their original technology is came from Qualcom company. Therefore the domestic phone makers only modify the source program and use them within limited applications. In this paper, we have developed our own DM system which is enable to solve the above problems and can be used as a test tool so that problems of phone communications are found easily and quickly. In addition, we will enhance this system to follow the current wireless technique by improving the protocol and enhancing the functions.
