DATENKOMMUNIKATIONSSYSTEM MIT ZUSäTZLICHER DATEN-URSPRUNGSINFORMATION

摘要

Gateway 3 receives mobile station data corresponding to mobile station 2 from switching center in mobile packet communication network 1 by NWMP, which is a communication protocol for administration data in mobile packet communication network 1. Mobile station 2 transmits and receives HTTP data in HTTP via gateway 3. In transmitting HTTP data from mobile station 2 to server 5, gateway 3 adds mobile station data corresponding to mobile station 2 as an expansion header of HTTP data. Mobile station 2 does not falsify mobile station data because the added mobile station data is administered in corresponding to identification data used in establishing wireless connection to mobile packet communication network for mobile station 2, and is transmitted and received in NWMP unavailable by mobile station 2. As a result, server 5 may trust mobile station data add to HTTP data transmitted from mobile station 2.
