Abstract: A management device managing terminal devices includes a memory, a receiver, a controller, and a transmitter. The memory stores: area management information in which area specifying information specifying an area where the terminal device is positioned and area kind information indicating characteristic of the area are associated with each other; and memory management information in which the area kind information and memory setting information on memory regions for respective functions used by the terminal device are associated with each other. The receiver receives a request message including the area specifying information of one of the terminal devices. The controller specifies the area kind information corresponding to the one terminal device based on the request message and acquires the memory setting information corresponding to the specified area kind information from the memory. The transmitter transmits the acquired memory setting information to the one terminal device.

Abstract: A first communication interface communicates with one of a plurality of base station devices according to a first communication scheme. A second communication interface communicates with a further terminal device according to a second communication scheme different from the first communication scheme. A controller selects a base station device that the first communication interface should communicate with based on base station information received in the second communication interface from the further terminal device and related to the base station device that the further terminal device is communicating with.

Abstract: In a business wireless system, a group including a plurality of terminal devices is formed and communication is performed by using at least one base station device to assign a channel to each group. A transmission unit uses a channel assigned by the base station device to a first group for transmission. An authentication processing unit authenticates a user using the terminal device. A selection unit selects one of a second group that only the terminal devices for which the authentication process is completed can subscribe to, and the first group, when the authentication process is completed. When the second group is selected, the transmission unit the channel assigned by the base station device to the second group for transmission.

Abstract: A communication system is provided in which multiple terminal devices form a group and at least one base station device assigns a channel to each group, so that communication from a terminal device included in a group assigned a channel to the other terminal devices included in the group is performed. In the communication system, a transmitting unit transmits information about authentication to a base station device before communication is started. A receiving unit receives, from a base station device, information about authentication status of at least another terminal device within the group.

Abstract: A wireless device is possessed by a user. A reporting unit reports, to a management device, status information regarding the surrounding environment of the wireless device and position information of the wireless device. A requesting unit requests the management device to perform guidance to an evacuation route. An accepting unit accepts an instruction for guidance to an evacuation route from the management device when the requesting unit does not request guidance. A notification unit performs notification of an evacuation route.

Abstract: A receiving unit receives positional information of a terminal device. A storage unit stores a list in which a plurality of correspondence relationships between an area and an identifier are included. An adjusting unit adjusts the correspondence relationship included in the list. A first selection unit selects, from the adjusted list, an identifier corresponding to the received positional information. A first transmission unit transmits the selected identifier to the terminal device. An input unit inputs information on an area to be called. A second selection unit selects, from the adjusted list, an identifier corresponding to the input information. A second transmission unit transmits a call signal including the selected identifier.

Abstract: An acquisition unit acquires positional information. A storage unit stores a list in which a plurality of correspondence relationships between an area including positional information that can be acquired in the acquisition unit and an identifier are included. A selection unit selects, from the list stored in the storage unit, an identifier corresponding to the positional information acquired in the acquisition unit. A communication unit receives, from a calling device, a call signal including an identifier to be called. A control unit makes, when the identifier included in the call signal received in the communication unit matches the identifier selected in the selection unit, the communication unit execute communication.

Abstract: A reception unit receives positional information of a terminal device from the terminal device via a base station device that uses at least one of a plurality of channels. A generation unit generates channel information related to a channel in scan processing of the terminal device on the basis of the positional information received by the reception unit. A transmission unit transmits the channel information generated by the generation unit to the terminal device via the base station device.
