Research And Implement Of SMS Middleware Based On CDMA Network

The SMS(Short Message Service) get the quick development and application as the importance increasing in value of the Mobile Communications. The short message is simple and direct, convenient, economic, simple operation, wide network overlay etc. having become the important information exchanges tool of the people's life and enterprise application. Complicated technology of SMS is encapsulated as the Middleware, have a better research and apply value.This topic based on the CDMA network, according to the Middleware theories, adopting the rock-bottom development technology of the Modem designed and carried out the SMS Middleware, provided a good SMS support function for a middle-small business enterprise and middle-small application. Passing to analyze and research the GPRS and the CDMA network, the AT command of wireless Modem choose using the CDMA network and HUAWEI Modem as the network supports of system and choosing a type of the hardware; In the cross-platform database, this paper design and carried out a cross-platform database engine making use of the O/R Mapping technology, resolve the problem of the cross-platform database based on the Object Oriented model; In the junk message filter, system comprehensively making use of the black and white list technology and Bayes arithmetic, availably prevent from the junk message; In the design and Implement of SMS engine, adopting multi-threading synchronization arithmetic of resources access technology, can effectively resolve hardware resources dead lock problem, adopting software fault-tolerant technology can resolve error automatically trapping and system automatically reset problem. Passing integration of the SMS Middleware, application can quickly carry out sending message, group sending, timing sending, automatic reply, the workflow of mobile office etc., consumedly improve reliability and development efficiency of application system. This topic research results have been applied in the "ERsoft Cooperation Office System" of Xian Enring Software Corporation, the system is stable and reliable, the anticipated goal has been achieved, a good result has been obtained.
