Abstract:
1. A mobile radio communication system estimating the positional relationship between the own moving terminal and the other moving terminal around a view obstruction, wherein the other moving terminal serves as a transmitting station in the mobile radio communication system and includes a transmission antenna having a predetermined transmission power level and a predetermined mounting height, wherein the own moving terminal serves as a receiving station in the mobile radio communication system and includes wherein, if the absolute value is lower than the first power threshold value, the own moving terminal determines that the other moving terminal is positioned within the visual range of the own moving terminal, the distance from the own moving terminal to the other moving terminal being shorter than a predetermined distance B wherein, if the absolute value is higher than or equal to the first power threshold value, the own moving terminal determines that the other moving terminal is positioned within the visual range of the own moving terminal, the distance from the own moving terminal to the other moving terminal being longer than or equal to the predetermined distance B
