Abstract:
1. A radio service area quality information acquisition system comprising: a base transceiver station that communicates with a plurality of wireless access terminals, and measures and outputs a performance value indicating a throughput of its own apparatus, the number of call connections, or the usage rate of the base transceiver station capacity; and a maintenance apparatus that acquires area quality information of a radio area of the base transceiver station in accordance with the performance value of the base transceiver station, wherein the maintenance apparatus transmits a confirmation signal to the plurality of wireless access terminals through the base transceiver station, receives an identifier of the wireless access terminal transmitted from one or the plurality of wireless access terminals having received the confirmation signal, stores the received identifier of the wireless access terminal correspondingly to an identifier of the base transceiver station, acquires a performance value of the base transceiver station from the base transceiver station, reads an identifier of a first wireless access terminal corresponding to the identifier of the base transceiver station in a case where the acquired performance value is a previously determined limit value or less, transmits an acquisition instruction of information to the first wireless access terminal in accordance with the read identifier of the first wireless access terminal, and acquires the area quality information including position information of the first wireless access terminal and radio waves information between the first wireless access terminal at the position and the base transceiver station, which is transmitted from the first wireless access terminal in accordance with the acquisition instruction.
