PROBLEM TO BE SOLVED: To eliminate the need of the design and the installation of a repeating station device and to reduce facility cost since it is necessary to install a radio repeating station for securing a service area when a radio wave does not directly arrive between a terminal and a base station, but the design and the installation of the repeating station device are required and facility cost increases in a radio communication system where the base station and the terminal perform communication through a radio line. SOLUTION: The terminal is used as the repeating station and a repeating route to the base station is set. |
