A wireless network control system includes a macrocell base station configured to form a macrocell, at least one small cell base station configured to form a small cell disposed within the macrocell, and a control apparatus including a controller configured to execute a process of acquiring a first value indicating a traffic state of a wireless terminal using the macrocell and a second value indicating a traffic state of a wireless terminal using the small cell, and a process of setting OFF the small cell when an added value of the first value and the second value falls within a predetermined range related to the macrocell.

Wireless network control system to perform on-off control for small cell

An apparatus stores first identification information in association with each of a plurality of base stations, where the first identification information identifies locations included in a wireless area that is formed according to transmission power control by each of the plurality of base stations. The apparatus controls, based on parameters indicating wireless communication capability at a target location that is included in a first wireless area formed by a first base station and identified by the first identification information, transmission power of a second base station which forms a second wireless area including the target location.

Apparatus and method for selecting an optimum base station whose transmission power is to be changed

An authentication device includes an authentication unit configured to determine whether an input password input to a input unit matches a registered password registered in advance in a storage unit, count the number of times it is determined that the input password does not match the registered password, and stops authentication using a password if the number of times a mismatch is determined reaches a specified number, and a management unit configured to create an input error list supporting each of characters, digits, or other elements included in the registered password, on the basis of a history of errors of input to the input unit, and configured to cancel counting in a case where it is determined by the authentication unit that the input password does not match the registered password and a cause of the mismatch lies in an input error included in the input error list.

Authentication device, authentication method, and recording medium

Predetermined information is received from an external device and when receiving the information, an area in which the data stored in the first memory shall be erased is determined corresponding to a battery residual quantity of a power supply unit of the arithmetic processing device, and a data erasing process is controlled and executed with respect to the thus-determined area.
