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.

Terminal device, management device, storage medium adapted for communication between multiple terminal devices within a group

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.

Terminal device, management device, communication system, memory medium, and communication method for notifying users of authentication status of multiple terminal devices within a group

An acquirer acquires parameters that correspond to a plurality of base station devices using a resource for communication with a terminal device and can be used for predicting a shortage of a resource of each base station device. A generator generates information relating to a priority level of a resource desired to be used by a terminal device connected to one of the plurality of base station devices in accordance with the parameters acquired by the acquirer. A transmitter transmits the information generated by the generator.

Management device, terminal device, and management method performing process of selecting resource of radio link

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.

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.

Calling device, communication system, and calling method for executing call for communication

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.

Terminal device, communication system, and communication method for executing call for communication

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.
