  • MONITOR DEVICE, BASE STATION, MONITORING METHOD, CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM
    Publication number: 20220014550
    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.
