Abstract
In recent years, data service has been gaining popularity in embedded system and general packet radio service (GPRS). In this paper, we first analysis the embedded system theory, short message service (SMS), and combine with the latest computer technology, network technology, communication technology and GPRS technology, then propose an method to design the short message service system based on ARM and GPRS. We put forward the system principle block diagram and the hardware circuit of GPRS. At the same time, we give the software process flow and specific algorithm, namely, GPRS initialization module, port 1 receiving interruption module, GPRS communicate with S3C2410's port 1 module and sending message module. This proposed technique is well suited for various applications and has good prospects.
