An automated stock price delivery system based on the GSM short message service

The development of value added services based upon the GSM standard is becoming increasingly important to both network operators and the subscriber´s to such networks. This paper outlines a system capable of delivering “real time” stock price information (e.g. price, volume etc.) from Internet based stock price servers to a variety of subscriber types. The main delivery mechanism for this information is the GSM short messaging service (SMS) but the system is also equipped with an interactive voice response (IVR) system in order to support an additional automated speech prompt based delivery mechanism. The system also supports the use of GSM equipped Windows CE based palmtop computers and personal digital assistants, as subscriber terminals for the system, by means of a suite of software for accessing and managing the stock price information delivered to these terminals by the GSM SMS delivery mechanism
