US Patent 7558584 Location reporting method and related mobile communication terminal

Menu data supplied from an IP server 500 to a mobile station 101 is embedded with a location information substitution data string “NULLAREA” together with a URL of a particular IP server 500. The mobile station 101, upon detection of the location information substitution data string from a menu data selected by the user, determines whether location information can be transmitted to the IP server 500. In the case where the determination is that the transmission is permitted, the mobile station 101 detects its location information and, after substituting the location information for the location information substitution data string, transmits the data to the IP server 500.
