  Based on the base station information extracted by the base station information extraction unit 103a (including a script for generating guidance guidance information), the guidance information generation unit 106 guides the terminal user into the communication area of the living base station. Guidance information is generated.

  The input operation unit 108 includes various key switches and accepts an input operation of a terminal user. The positioning unit 109 measures the current position of the wireless terminal MN. The base station information storage unit 110 temporarily stores the received base station information.

  In such a configuration, when a disaster such as an earthquake occurs and a part of the radio base station AP becomes malfunctioning due to damage or the like, the base station monitoring device 4 determines the life and death state for each radio base station AP. The position information such as the address, latitude and longitude of the living base station is notified to the broadcasting station 1 via the IP network as base station information together with a script for generating guidance information.
