<p><P>PROBLEM TO BE SOLVED: To provide a radio system having a plurality of radio units connected to an upper-level device in cascade, enabling effective management of a system configuration by the upper-level device. <P>SOLUTION: For each cascade-connected radio unit 2, an upper-level device 1 includes a system configuration management table 11 for storing stage information, indicative of a connection position (stage) in the cascade connection, an ID of the radio unit 2 and an IP address of the radio unit 2, in an associated manner. Based on the contents stored in the system configuration management table 11, the upper-level device 1 transmits a connection establishment request for a link connection to each radio unit 2, in order from the upper-level side of the cascade connection, and receives connection information from the radio unit 2 having an established link connection based on the connection establishment request, and further, determines whether an ID and an IP address included in the connection information conform to the contents stored in the system configuration management table 11. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
