Intelligent, non-intrusive, adaptive wireless discount coupon delivery system over GPRS

   
   

An intelligent, non-intrusive, adaptive wireless discount coupon delivery system over General Packet Radio Service ("GPRS") bearer service. The system generates and delivers electronic coupons to subscribers' GPRS mobile stations from business entities in the subscribers' vicinity. The system bases its delivery on the subscribers' profiles stored in their mobile phones, which may include their cellular location and their shopping histories. The main components of the system include: a GPRS mobile station, a base station, a mobile-switching center ("MSC"), a serving GPRS service node ("SGSN"), a coupon generating server ("CGS"), an offer generating server ("OGS"), and store pricing databases. The system increases the facility and trustworthiness of wireless coupon delivery by isolating subscriber profile information from stores' pricing databases.
