Campus Short Message System Based NET Design And Implementation

Because of the convenience and good interactivity, mobile phone text message is considered as the "fifth media" after newspapers, radio, television and the Internet. SMS-based applications and business is growing rapidly. With the rapid development and wide application of Internet, Internet access became an important channel of rapid publication and dissemination of information. In this paper, short message service and Internet are combined to develop a Web-based Campus Short Message System, which has practical value and application prospect.First, study the current status of Short Message platform development, bulk SMS platform for application in various fields and the Short Message System technology. It includes development of technologies WEB,SMS, AT commands programming.Second, this paper presents a combination of the actual situation in a school designed to process bulk SMS platform. First of all, needs analysis to determine the construction of the system, functional requirements and non functional requirements. Then, in the requirements made on the basis of objectives and principles of design were carried out on the summary of the whole system architecture design. WEB application to determine the SMS+ background overall pattern of the module, in the middle using database connection. WEB page program is designed for front end user, the user through web content to compose a message, for system management, operation, and to edit the text stored in the database; background SMS sending module written in VC++ using the SMS process, real-time database read In the SMS message, using text messages sent to the recipient cat. Next, on the basis of the outline design, the paper will design, coding, testing and improvement the application from WEB applications and back-WEB SMS generator module in detail.After consulting a large number of domestic and foreign related systems and software development technical data, the paper shows the system requirements analysis, structural and functional design and database design. The system is implemented with VS2005 as development tool, C# as development language, SQL Server 2005 as the database server, GSM-SM Modem providing hardware support, using middleware of GSM-SM Modem and Ajax Technology based on Browser/Server model and object-oriented design thoughts. The main functions of this system include text messaging, SMS management, system management, user management, and student management. It can be used for various departments in a University to send all kinds of information. For example, the finance department can send salary payment information, and the Teaching Affairs Department can send score information to students. The system is user-friendly, simple to operate, and has good running speed, security, stability and maintainability.Third, improvement of the Short Message platform. There are some problem when this system is developed, which is long SMS processing, handling lost messages, message receipt process. These be solved and descried in the paper. We hope it can be used in the other Short Message platform.In addition, based on the. NET Short Message System of Campus has the following obvious characteristics.First, the text data source can be more diverse. Users can read from the data in Excel form, which is put into their message content, Example, each employee's salary information will be combined into a text message sent to each employee; You can also manually enter the message content, if sent to each employee notice of the same; Similarly, we also support the system from other applications to send text messages to read specific content.Second, the system supports analyst of SMS sending State. Because the messages sent are not connection-oriented, some cell phones maybe can not receive the SMS, because of power off and NO signal. We analyze the status of SMS message, to determine whether the SMS was properly received. If not accepted, messages will be re-send using a certain strategy.Third, supporting for long messages. In practice, message content may take longer in the SMS group send process. However, a content of message is not more than 70 characters in the Protocols of the GMS. So the message will be split and sent when the content of message is to long. Distribution of message solution will be described in the paper.
