Design And Implementation Of The Wireless Message Services Of CDMA Mobile Terminal

In the Modern Communication Technology, CDMA (Code Division Multiple Access) communication technology is one of the most popular communication technologies. It is popular with many people because its connection quality is good and its transmission speed is high. The Wireless Messaging Service module is one of the basic modules of CDMA mobile terminal. The Wireless Messaging Service module also is the difficult point in the development of CDMA mobile terminal, because this module architecture is complex, involves many circumstances and needs frequent interaction with the various modules.The content of this article is based on the CDMA mobile communication technology and the develop platform (BREW) of QUALCOMM Incorporated. It introduces the phylogeny of CDMA technology, the standard of CDMA technology. It introduces Real-Time Executive system (REX). It also introduces many mechanisms of BREW and the relationship between BREW and REX. We started requirements analysis according to the customer's requirements after studied to the BREW platform. First, we establish requirements models. Then we can get the function that must be achieved through analyzing requirements models. Second, we can drive the detailed development of the Wireless Messaging Service module according to the results. The development flow can guide us to code and implement Wireless Messaging Service module easily. The CDMA Mobile terminal can be provided to the customer after testing strictly.
