<P>PROBLEM TO BE SOLVED: To easily obtain an adjoining relationship of wireless base station devices in wireless communication and a distance between the wireless base station devices. <P>SOLUTION: A wireless base station control device 1 receives and stores (S301 and S302) the output power information of a wireless base station device CS. When a notification sent from a wireless terminal device PS indicating that the wireless base station device CS is changed is received (S303), based on the power information of the wireless base station device before a change included in the notification, the power information of the wireless base station device after the change, and the output power of the wireless base station device CS, a distance between the wireless base station devices is calculated (S304). When the calculated distance is not written in a CS location information table 32a or it is shorter than a distance already stored, the CS location information table 32a is updated to the calculated distance. and stored (S305, S306, S307 and S308). <P>COPYRIGHT: (C)2009,JPO&INPIT |
