Abstract: A reporting method includes: obtaining an address that is assigned to a target device and that is included in a control signal used for a communication with an access point in a plurality of access points; storing identification information in a storage in association with the address of the target device; storing, when receiving report destination information, the report destination information in the storage in association with the address of the target device if identification information reported in association with the report destination information is stored in the storage; referring to the storage when obtaining information of a control signal received by one of the plurality of access points; and reporting, when a source address of the control signal exists in the storage, to a report destination stored in association with the source address that there is an access from the target device.

Abstract: A control device includes a control unit configured to transmit a login screen including an input section for an answer to a questionnaire to a mobile terminal that is not permitted to access a wireless access network, when a connection request is received from the mobile terminal, receive login information and an answer to the questionnaire input in the login screen, and issue an access permission to the mobile terminal for communication through the wireless access network when reception of the answer to the questionnaire and authentication of the mobile terminal based on the login information are complete.

Abstract: An access point notification method causing a control device that controls one or more access points to execute a process, the process include: identifying an access point based on disaster information and transmitting, to the access point, a transition instruction to instruct a transition of a setting of the access point to a disaster setting by which communication using a second identifier, different from a first identifier for which the access point allows communication, is allowed; transmitting to a notification server a request for authentication information; notifying the notification server of the information on the access point, using the authentication information; and causing the notification server to register the information on the access point the setting of which is transferred to the disaster setting and transmit a notification message to the terminal that is the distribution destination.
