Abstract�� Based on the study of short message communications model, a short message communications gateway was carefully designed and implemented so that the vehicular devices can connect to multi reporting centers conveniently and transparently. In order to improve the gateway's performance, the concepts of queue, hash, and buffer storing were used in the design, and the techniques of multithread,message communication, and ActiveX control were used in the implementation. Testand practical operation demonstrated the high efficiency and reliability of the proposed gateway, and they also confirmed the design concept and completion techniques.
