Research On A Group SMS Platform Based On GPRS

With the rapid development of the Chinese communication trade, SMS and various kinds of SMS based on SMS were emerged in an endless stream. The SMS sent was 20 million every day, 8% to 20% of the incomes of GSM operator came from SMS, how to solve a group of SMS sent became the topic that the operator paid close attention to together now.GPRS was an important milestone of GSM data business. It was offered the new data service and made operator offer brand-new pricing right for the users, GPRS business was commercial users' goal, the extensive adoption and accepting of GPRS would create a large quantity of uses, thus could lower costs while offering better business. Because of fast development of SMS business and GPRS, how to combine the two together well became the key point of a subject.Firstly, the research background of the subject, the kind of SMS business and development of GPRS goal were introduced in the dissertation. A group of SMS system based on GPRS research current situation and development prospect are presented. Meantime, technical requests and system index were given in this dissertation. Secondly, according to data collection channels, message data quantity and system function, making choices in fore-inputting methods of the system and research on system functions. Thirdly, on the basis of design of the whole system, the system hardware architectures has been designed, fully each unit of hardware has been analyzed in this system. Thoughts, design gist and hardware peripheral circuits were designed in this dissertation. According to system functional requests and hardware design, it has been accomplished working software using system software architectures of digital signal processor, including AT command, PDU code, communication protocol, one-chip computer control procedure and explaining of SMS develop interface. At last, it was summarized the system and looked into the distance.Through carrying on the function analyzed and succeeding in debugging to this system, it was proved the structure of the system reasonable in design, interface simple, function abundant and performance well, reached the request designed systematically. The system combined a group of SMS sent and GPRS function together well. It was not being restricted by topographical condition and was captivating application prospects.
