Abstract: An object is to provide a monitor device capable of reducing threat of DoS attacks on a mobile network. A monitor device (10) according to the present invention includes a signal monitor unit (11) for estimating a specific base station communicating with a communication terminal (30) attacking a mobile network according to the number of times an ATTACH procedure is rejected, in which the ATTACH procedure is for registering information about a communication terminal (30) communicating with a base station (20) in a communication device (40) located in the mobile network, and a base station control unit (12) for causing the specific base station to determine whether to execute the ATTACH procedure related to a communication terminal served by the specific base station according to communication terminal identification information set in a signal transmitted from the communication terminal served by the specific base station.

Abstract: A base station includes a wakeup signal transmission part transmitting transmission signal information to a wireless terminal by wireless communication. The transmission signal information includes a wakeup signal starting a given function included by the wireless terminal. The wakeup signal transmission part transmits the transmission signal information including connection information in addition to the wakeup signal to the wireless terminal. The connection information is information for causing the wireless terminal of a destination of transmission of the wakeup signal to connect by wireless communication using the given function.
