Abstract

A relay apparatus capable of reducing noise received by a base station device. In this relay apparatus (100), a data analysis section (131) compares an output level of a digital filter (123) and a predetermined threshold value, determines that a terminal signal is included when the output level is the threshold value or more, and determines that the terminal signal is not included and only noise exists when the output level is less than the threshold value. A radio control section (132) controls an antenna switch (133) so that an upstream signal radio section (120) and a shared device (103) are connected when the data analysis section (131) determines that the terminal signal is included in an output of the digital filter (123), and controls the antenna switch (133) so that the upstream signal radio section (120) and a termination section (134) are connected when the data analysis section (131) determines that the terminal signal is not included in the output of the digital filter (123).
