Enterprise informatization construction is able to enhance the sustainability of rapid national economic development, strengthen the country's comprehensive national strength, help enterprises meet the challenges after WTO accession, adapt enterprises to international competition, and to some extent improve the working environment of workers. Informatization construction is necessary for enterprises which are seeking for development.As mobile communication technology is developing rapidly, as a mobile communication's business, an important value-added SMS (Short Message Service) has also been developing rapidly. In the process of Enterprise informatization construction, Applications of short message gradually play an increasingly important role, and actively promote the enterprise's rapid development.There are a total of seven chapters in this paper. Chapter one introduces the current development of enterprise informatization at home and abroad. Chapter two analyses the advantages of the choice of GSM networks from many ways of wireless communications and the features of GSM networks's data services - SMS. Chapter three introduces the interface function and pin function of the communication module TC35i used in this system. Chapter four does a more detailed design of the most crucial communications layer, introduces the AT commands and PDU encoding. Chapter five does the analysis and design of GSM MODEM communications for multi-threaded program. Chapter six introduces the overall structural design of the message system which was based on the GSM network, and introduces the system's role and function. Chapter seven of this paper does a review and proposes some suggestions for improvement in the future.This paper presents the way by which people can access to enterprise's database information by using GSM short message.
