STOCK TRADE SYSTEM BASED UPON HAND-HELD DEVICE

摘要

PURPOSE: Provided is a stock trade system based upon a hand-held device by allowing a message adapter(MA) to send to a stock transaction subsystem(STSS) a request in a characteristic message format that the STSS requires. CONSTITUTION: A service platform subsystem(SPSS)(3) communicates with various hand-held devices according to characteristic communication methods and message formats that those devices employ and receive stock trade requests that users of the devices issue. Here, MAs(4,4') are in charge of message format conversion between the SPSS(3) and STSSs(5,5'). When the SPSS(3) receives a stock trade request, the request is sent in standardized platform message format to the MA(4) (e.g. MA#1) connected to the STSS(5) (e.g. STSS #1) that a user specifies. The MA(4) once receiving the requests sends it in the message format needed for the STSS 1. Finally, a stock trade center achieves the request.
