Method and system for distributing providers to interested parties

摘要

Supplier profile data (111) and product data (112) are stored in supplier communications server (1) and transmitted to communication end units (3) of prospective customers who access supplier server via communication network (2). Supplier end unit (4) provides current geographic position. Certain suppliers register at the supplier communications server (1) using mobile end units (4). Mobile end unit has registering program (45) to automatically generate a registration document which is transmitted to supplier server (1) via mobile radio network (2) e.g. GSM, UMTS network, Internet or cable television network. Document contains supplier identification, taken from identification module of end unit (4) and current geographic position of unit (4), determined by position determining unit (44). Identification and position data are stored as part of supplier profile data (111). Position data is periodically compared with newly determined position and new value transmitted when specific distance between them is reached. Also amount of time of position validity, is determined. When customer accesses server (1), current geographic position of customer is provided to server, and data (111,112) provided to customer (3). Digital certificate is derived from registration program (45) and used to detect manipulation of program.
