Then the paper described the function composition and the net frame of the platform. After that, the paper gave the sofeware architecture of the platform, which includes three layers:network layer, application layer and terminal layer. The network layer was designed by Java Socket API,using long link with design of link check and backup mechanism. It also designed a group a Java Class to implement the UASP and CMPP communication protocols.The application layer contained three access way--SMS,web and IVR. SMS is designed by using Java multithread to deal with the sending and receiving of the short messages;web is designed by using Struts and IVR is designed by programing voice card.
