Design And Implement Of Applicat Ions On GSM SMS Platform

As the rapid development of the mobile communication technology, one of the important value added serviceof mobile communication—Short Message Service (SMS) gets rapid development, too. During the construction ofthe informatization of enterprises, the application of SMS has become more and more important and contributed alot to the rapid development of the informatization of enterprises.This paper is mainly on construction of the model of short message platform, analysis of design ideal andresearch on technology of path, then giving out applicable examples on the basis of model. In order to insurehigh expansibility and incompact degree of coupling, three layer structure have been designed in this paper:interface communication module layer (SMS Control,for short SC),receiving and sending short message layer(SMS PlatForm,for short SP) and applying short message layer(SMS Application,for short SA) .Also, in orderto guarantee the independence of SC, orders of hardware communication have been encapsulated to standardcontrol by means of ActiveX technology in designing.In the first two chapters, the article makes clear the background, meaning and the main content of theresearch, and affords technical foundation for deep analysis of the model of SMS in the latter part. In the next threechapters, the article introduces the technical models of SC, SP and SA separately in detail. The key of the article isSC, and the main content of it involves the realization of communication between computers and mobile phones byMScomm control, the realization of kinds of control of mobile phones and the operation of sending and acceptingSMS by AT command, the analysis of PDU(Protcol Data Unit)of sending and accepting SMS, and the codingand decoding of the content of SMS, the number of the phone, the number of SMSC (Short Message ServiceCenter) and timestamp, etc. Then the author explains the way of design of SP, which is on the base of SC, and theconcrete method to realize it. In the end, the article gives an instance of SA, which is on the base of SP"thesystem of checking salary"toexplain the rationality and feasibility of the model of SMS Plat Form.
