CONTROL DEVICE, TERMINAL APPARATUS, AND COMMUNICATION SYSTEM
First Claim
1. A control device, comprising:
- an authentication unit configured to perform authentication of a terminal apparatus to be connected to the control device via a predetermined network;
a main control signal transmitting unit configured to transmit a main control signal at first transmission intervals, the main control signal being a control signal including information for performing data communication in synchronization with the terminal apparatus;
a sub-control signal transmitting unit configured to transmit a sub-control signal that is a control signal notifying the terminal apparatus that the authentication unit is in a state of accepting a request for the authentication; and
a signal control unit configured to control the main control signal transmitting unit and the sub-control signal transmitting unit,wherein the signal control unit is configured to determine whether or not the authentication unit is in the state of accepting the request for the authentication, and cause the sub-control signal transmitting unit to transmit the sub-control signal at second transmission intervals when it is determined that the authentication unit is in the state of accepting the request for the authentication, the second transmission intervals being shorter than the first transmission intervals.

Abstract
A control device includes: an authentication unit that performs authentication of a terminal apparatus to be connected to the control device; a main control signal transmitting unit that transmits, at first transmission intervals, a main control signal that is a control signal including information for performing data communication in synchronization with the terminal apparatus; a sub-control signal transmitting unit that transmits a sub-control signal notifying the terminal apparatus that the authentication unit is in a state of accepting a request for authentication; and a signal control unit that controls the main control signal transmitting unit and the sub-control signal transmitting unit, wherein the signal control unit causes the sub-control signal transmitting unit to transmit the sub-control signal at second transmission intervals shorter than the first transmission intervals when it is determined that the authentication unit is in the state of accepting the request for authentication.

9. A terminal apparatus, comprising:
-
a receiving unit configured to receive a control signal transmitted by a control device to be connected to the terminal apparatus via a predetermined wireless network; a determining unit configured to determine whether or not the control signal includes a sub-control signal that is a control signal indicating that the control device that transmits the control signal is in a state of accepting a request for an authentication for authenticating a terminal apparatus that performs data communication; a selecting unit configured to select the control device that has transmitted the sub-control signal as a management apparatus that is a control device to which the authentication is requested, when the determining unit determines that the control signal includes the sub-control signal; and a transmitting unit configured to transmit, to the management apparatus, the request for the authentication. - View Dependent Claims (10, 11, 12, 13, 14, 15)

17. A method for controlling a control device, comprising:
-
transmitting, at first transmission intervals, a main control signal to a terminal apparatus to be connected to the control device via a predetermined network, the main control signal being a control signal including information for performing data communication in synchronization with the terminal apparatus; determining whether or not an authentication unit that performs authentication of the terminal apparatus is in a state of accepting a request for an authentication; and transmitting a sub-control signal at second transmission intervals when it is determined that the authentication unit is in the state of accepting the request for the authentication, and not transmitting the sub-control signal when it is determined that the authentication unit is not in the state of accepting the request for the authentication, the second transmission intervals being shorter than the first transmission intervals, and the sub-control signal being a control signal notifying the terminal apparatus that the authentication unit is in the state of accepting the request for the authentication. - View Dependent Claims (18)

19. A method for controlling a terminal apparatus, the method comprising:
-
receiving a control signal transmitted by a control device to be connected to the terminal apparatus via a predetermined wireless network; determining whether or not the control signal includes a sub-control signal that is a control signal indicating that the control device that transmits the control signal is in a state of accepting a request for an authentication for authenticating a terminal apparatus that performs data communication; selecting the control device that has transmitted the sub-control signal as a management apparatus that is a control device to which the authentication is requested, when it is determined that the control signal includes the sub-control signal; and transmitting, to the management apparatus, the request for the authentication. - View Dependent Claims (20)
