Abstract

A wireless base station includes a storage unit and a processor. The processor transmits to a first wireless terminal a first request for transmitting a first response including first identifiers used to identify a first base stations. The first wireless terminal is capable of receiving a signal from each of the first base stations. The processor receives the first response from the first wireless terminal. The processor stores the first response in the storage unit. The processor transmits to a second wireless terminal a second request for transmitting a second response including second identifiers used to identify second base stations. The second wireless terminal is capable of receiving a signal from each of the second base stations. The processor receives the second response from the second wireless terminal. The processor determines whether the wireless base station has been displaced based on the first identifiers and the second identifiers.

Claims (20)

1. A wireless base station comprising:

a storage unit; and

a processor to

transmit to a first wireless terminal a first request for transmitting a first response including first identifiers used to identify first base stations, the first wireless terminal being capable of receiving a signal from each of the first base stations before transmitting the first response,

receive the first response from the first wireless terminal,

store the first response in the storage unit,

transmit to a second wireless terminal a second request for transmitting a second response including second identifiers used to identify second base stations, the second wireless terminal being capable of receiving a signal from each of the second base stations before transmitting the second response, receive the second response from the second wireless terminal, and determine whether the wireless base station has been displaced based on the first identifiers and the second identifiers.

2. The wireless base station according to claim 1 , wherein

the first response includes first reception quality information representing reception quality of the signal received from each of the first base stations,

the second response includes second reception quality information representing reception quality of the signal received from each of the second base stations, and

the processor determines whether the wireless base station has been displaced based on the first identifiers, the first reception quality information, the second identifiers, and the second reception quality information.

3. A displacement detection method comprising:

transmitting to a first wireless terminal a first request for transmitting a first response including first identifiers used to identify first base stations, the first wireless terminal being capable of receiving a signal from each of the first base stations before transmitting the first response;

receiving the first response from the first wireless terminal;

storing the first response in a storage unit;

transmitting to a second wireless terminal a second request for transmitting a second response including second identifiers used to identify second base stations, the second wireless terminal being capable of receiving a signal from each of the second base stations before transmitting the second response; receiving the second response from the second wireless terminal; and determining, by a wireless base station, whether the wireless base station has been displaced based on the first identifiers and the second identifiers.

4. The displacement detection method according to claim 3 , wherein

the first response includes first reception quality information representing reception quality of the signal received from each of the first base stations,

the second response includes second reception quality information representing reception quality of the signal received from each of the second base stations, and

the wireless base station determines whether the wireless base station has been displaced based on the first identifiers, the first reception quality information, the second identifiers, and the second reception quality information.
