The Studying And Realization Of Sms Transfer

The service of point to point short message is one of the development potential services of mobile communication, and it develops very fast.At present ,dig the potential of SMS and consummate the functions, has become a question for discussion to develop the SMS.The SMS transfer is one of operation requirement during the consumer using the mobile station. According to realize the SMS transfer, this paper content describe 3 schemes, including the bypass of the HLR, the way of of SMS center and the way of SMS monitor. To analyze the characteristic of these 3 schemes, the way of HLR and the way of SMSC need much cost and long time to emploitate . After studying the message flow of SMS, we have derived the following proposal to implement SMS Transfer Service by using SMS monitoring .The proposed operating system of the SMS Monitoring service is based on Window platform using SMPP protocol (SMS point to point protocol). The system procedure will be written in VC++; the backend database will be SQL Server 2000. The major components of the system include: subscriber registration parameter, monitored subscriber SMS parameter, the structure SMS parameters, database related to subscribers register message lists and subscribers SMS lists. The hardware components consist of one application server and one database server.The paper particular analyzes the security of the scheme of SMS monitor, also describe the system's structure of software and hardware, and tells the folws of adding and canceling the service. Including the software flow charts and multi-line flowcharts ways.The proposed system which implements the SMS transfer via SMS Monitoring istechnically superior in that this is the first ever software only implementation for SMS transfer in the Unicom network. With lower hardware cost, this solution not only compliments and brings added value to the existing services.
