Systems and methods for a radio communications device supporting LTE cellular communications. A device includes a data interface configured to exchange modem control commands and audio data with an LTE cellular modem and a telephone interface configured to provide a two-wire analog telephone interface for connection to a telephone device. A controller control signals provided via the telephone interface to manage voice call operations with the telephone device; exchange digital voice data corresponding to voice signals exchanged with the telephone device via the telephone interface; exchange control information via the data interface to establish and manage a voice over LTE cellular call; and exchange the digital voice data via the voice over LTE cellular call via the LTE cellular modem.

A control method of an information processing device that communicates with a communication device includes accepting a connection processing instruction to connect the communication device with at least one external device, and performing processing to execute newly, in a case that the connection processing instruction is accepted and the communication device is not connected to any external device, the connection processing.

A communication apparatus includes a reception unit that receives a Bluetooth® beacon signal transmitted from a printing apparatus, an identification unit that identifies a reception field intensity of the beacon signal, a display unit that displays a reception screen for receiving a transmission instruction in a case where the identified reception field intensity is less than a first threshold and greater than or equal to a second threshold that is smaller than the first threshold, and a transmission unit that transmits, to the printing apparatus, an authentication request enabling a user to log into the printing apparatus in response to receipt of the transmission instruction.

A server includes memory, a connection establisher, a first transmission request receiver, a first determiner, a first screen data transmitter, a second screen data transmitter, and a first disconnector. The connection establisher establishes continuous connection with a communication device. The first transmission request receiver receives a first transmission request t for displaying a setting screen corresponding to a first type of service. In response to the first transmission request being received from the external device, the first determiner determine whether a second type of service is currently provided. The first screen data transmitter transmits first screen data for displaying a first setting screen to the external device in response to the first determiner determining that the second type of service is not currently provided. The first disconnector disconnects the continuous connection in response to selection of a disconnection button included in the first setting screen displayed on the external device.

A communication device may cause an output unit to output first specific information obtained by using a first public key in a case where a first specific signal is received from a first external device, receive a first authentication request in which the first public key is used from the first external device which has obtained the first public key, send a first authentication response to the first external device in a case where the first authentication request is received from the first external device, and establish a first wireless connection with the first external device in a case where the first authentication response is sent to the first external device.

Systems and methods are provided though which a transaction, e.g., in a multi-tier, distributed application may be initiated from a portable or hand-held device, such as a smartphone. A computer system or systems, possibly remote from the device, may approve the transaction, complete it, or both, and the remote computer system or systems may cause a document to be printed, e.g., by a printer physically proximate to the device. Aspects of the invention are illustrated by embodiments in which a drug prescription may be created electronically using a hand-held device. In such an embodiment, the prescription may be transmitted to one or more remote computer systems, such as an application server, for processing. If specified, the remote computer systems may cause a prescription to be printed, e.g., at a printer near the prescriber's location. The prescriber may sign the printed prescription and give it to a patient or pharmacy.

An information processing device includes a display, a communicator, and a controller, in which the controller acquires destination information managed by a terminal device via the communicator and displays the acquired destination information on the display in accordance with its priority level.

An image forming system that is convenient for a user even when an image forming apparatus is directly connected to a network in addition to an image control apparatus. The image forming system includes an image control apparatus and an image forming apparatus. The image control apparatus includes a first communication member connected to an external apparatus through a network, a second communication member connected to the image forming apparatus through a predetermined transfer path, and a port controller that controls switching of a predetermined network port of the first communication member. The image forming apparatus includes a third communication member connected to the external apparatus through the network, and a fourth communication member connected to the image control apparatus through the predetermined transfer path. The port controller closes the predetermined network port in a case where both of the third and fourth communication members are valid.

In a communication system including a communication apparatus and a communication terminal which are able to perform wireless communication with each other, the communication apparatus includes a first wireless communication interface conforming to a Bluetooth standard and including a plurality of antennas, and the communication terminal includes a second wireless communication interface conforming to the Bluetooth standard and one or more controllers configured to acquire angle information and radio field intensity information based on a result of a plurality of radio waves respectively emitted from the plurality of antennas having been received by the second wireless communication interface, and, in response to the angle information and the radio field intensity information having satisfied a predetermined condition, transmit a request for establishment of wireless communication conforming to the Bluetooth standard to the first wireless communication interface via the second wireless communication interface.

An information processing apparatus includes a registration unit and a processing unit. The registration unit registers multiple terminal devices with the information processing apparatus or a different apparatus in association with multiple operators who operate the multiple terminal devices. The processing unit executes a process by performing, in response to an instruction for the process given by a specific one of the operators, short-range communication with a specific one of the terminal devices that is registered in association with the specific one operator.
