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.
