Development, Based On The Fixed Telephone Network Of The Chinese Short Message Terminal

In this study, we develope the software and hardware of SMTE(Short Message Terminal Equipment) based on the PSTN (Public Switched Telephone Network) by using Chinese Terminal Service Interface (CTSI) protocol . This SMTE is special for retail chain.In chapter 1 ,we present the foreground of PSTN increment service in the small scaled retail chain business enterprise.In chapter 2,we we expatiate an electronic commerce network structure face to retail chain and the whole structure of SMTE's software and hardware.In chapter 3,we use W925E/C240 which produced by Winbond Company to design the circuit based on the Calling Identity Delivery(CID) to receive and dispatch information, and via SPI ,design an whole module using P89LPC932 which produced by Philips Company to receive and dispatch short message on these grounds.In chapter 4,we partularly design the software of the SMTE, include the function of FLASH'S reading and writing , the function of SPI ,etc. Then we design the data structure of the various business data and the function of coding and decoding.In chapter 5,Firstly ,we present CTSI protocol and its enhanced version. Then we use it to complete various functions of electronic commerce network in the small scaled retail chain business enterprise like the management of order,deal and stock.In chapter 6,we perspect the current of the SMTE.
