Design And Realization Of Mobile-commerce System Based On SMS And WAP Push

The wireless communication technique and the Internet technique developing at a very fast speed and syncretizing to each other gradually, makes mobile commerce grow vigorously. Under mobile commerce, people can breakout of the restrictions of time and space, and obtain key information at any time and anywhere. Consumers oriented originally, mobile commerce are gradually applied to enterprises.With the rapid development of mobile communication technology, SMS (Short Message Service), one of the most important value-added services of mobile communication, has been improved violently too. SMS has been used in production and management to improve the information contacting efficiency. PUSH technology used in mobile network-WAP Push has a good application foreground because it is featured with active and on-time message sending as well as receiving message at any time.At first, this paper introduces the definition, basic processing of SMS; based on WAP2.0 it researches the architecture and protocols of WAP, XHTML language applied in WAP; and the system frame, protocol and push mode of WAP Push are introduced. Then it analyzes and designs system requirement in general.The basic communication module is important and difficult in realizing the system functions and also is the emphasis of this paper. It mainly contains utilizing JAVA language to realize the serial communication between computer and cell phone module, utilizing AT command to realize the cell phone module control and SMS receiving and sending operation, the PDU (Protcol Data Unit) format analysis, SMS content, cell phone number, SMSC number, timestamp encoding and decoding.Finally, the paper introduces the realization of system function, the system interface design and operating test and summarizes the design experience and the work that shall be done in future.
