The Design Of Embedded Short Message Platform

With the widely popular of GSM mobile communication network and the drastically competition, the development and application of new technology and new business have already become very important, as a nationwide GSM network roaming and interconnection realized with network signal strong feature, users need to connect outside the network, not only improve the network coverage, and expensive for customers to.save aintenance costs and networking costs. GSM network while the number of users are not required to overcome the old post network communication system to maintain expensive, high investment costs, and coverage of network monitoring a limited number of small and user issues, compared to traditional cluster system in the wireless network coverage with unmatched advantages. SMS using GSM wireless communication system performance and stability are two-way data transmission for remote data transmission and monitoring system to provide a strong platform for communication. china mobile Internet market is in its infancy, it was realized compared with the Internet, short message over the number of users, covering a wide range, with mobility and interactivity, low cost, security is strong, can receive information anytime, anywhere, short message GSM network services business as a basic business, has been a growing number of system operators and system developers attention to a variety of applications based on this business also prospered.Paper first introduces the current development status messaging platform. second, embedded systems and messaging principles are introduced in detail, and then focuses on the whole system are the hardware and software design. system hardware design includes keyboard interface design, led interface design, Avalon switch fabric bus design and interface design and so part of the GSM module. designed and implemented system software to send instant messages, send regular text messages, receive messages and signal detection. At last the article points out the shortcomings.
