Abstract
An onboard relay device relays data which is transmitted and received between a first onboard device connected to a first network and a second onboard device connected to a second network, and includes: a determination unit configured to determine whether the first network is a target for cooperation control in which a network state is changed along with the second network; and a control unit configured to transmit a request associated with a change of the network state to the second network when first data has been received from the first onboard device in a case where the first network is the target for the cooperation control.

An onboard relay device that is configured to relay data which is transmitted and received between a first onboard device connected to a first network and a second onboard device connected to a second network, the onboard relay device comprising:
- a processor and memory configured to:
- receive a network management frame from the first onboard device indicating that the first onboard device is in a sleep-enabled state;
- determine, based on the network management frame transmitted from the first onboard device, whether the first network is a target for cooperation control in which a network state is changed for the first network and the second network;
- transmit a request associated with a change of the network state to the second network when first data has been received from the first onboard device and the first network is the target for the cooperation control;
- and
- not transmit the request associated with the change of the network state to the second network, but determine whether the onboard relay device is in a sleeping state when the first data has been received and the first network is not the target for the cooperation control;
- wherein the first onboard device is not the second onboard device.
An information processing method executable by a relay device that relays data which is transmitted and received between a first device connected to a first network and a second device connected to a second network, the information processing method comprising:
- receiving a network management frame from the first onboard device indicating that the first onboard device is in a sleep-enabled state;
- determining, based on the network management frame transmitted from the first device, whether the first network is a target for cooperation control in which a network state is changed for the first network and the second network;
- and
- transmitting a request associated with a change of the network state to the second network when first data has been received from the first device and the first network is the target for the cooperation control, and
- not transmitting the request associated with the change of the network state to the second network, but determining whether the onboard relay device is in a sleeping state when the first data has been received from the first device and the first network is not the target for the cooperation control;
- wherein the first onboard device is not the second onboard device.
A non-transitory storage medium storing a program, the program being executable by a relay device that relays data which is transmitted and received between a first device connected to a first network and a second device connected to a second network, the program being configured to cause the relay device to perform an information processing method when the program is executed by the relay device, the method comprising:
- receiving a network management frame from the first onboard device indicating that the first onboard device is in a sleep-enabled state;
- determining, based on the network management frame transmitted from the first device whether the first network is a target for cooperation control in which a network state is changed for the first network and the second network;
- and
- transmitting a request associated with a change of the network state to the second network when first data has been received from the first device and the first network is the target for the cooperation control, and
- not transmitting the request associated with the change of the network state to the second network, but determining whether the onboard relay device is in a sleeping state when the first data has been received from the first device and the first network is not the target for the cooperation control;
- wherein the first onboard device is not the second onboard device.
A relay device that relays data which is transmitted and received between a first device connected to a first network and a second device connected to a second network, the relay device comprising:
- a processor and memory configured to:
- receive a network management frame from the first onboard device indicating that the first onboard device is in a sleep-enabled state;
- determine, based on the network management frame transmitted from the first device, whether the first network is a target for cooperation control in which a network state is changed for the first network and the second network;
- transmit a request associated with a change of the network state to the second network when first data has been received from the first device and the first network is the target for the cooperation control;
- and
- not transmit the request associated with the change of the network state to the second network, but determine whether the onboard relay device is in a sleeping state when the first data has been received from the first device and the first network is not the target for the cooperation control;
- wherein the first onboard device is not the second onboard device.
An information processing system comprising:
- a first device connected to a first network;
- a second device connected to a second network;
- and
- a relay device that relays data which is transmitted and received between the first device and the second device, wherein the relay device includes:
- a processor and memory configured to:
- receive a network management frame from the first onboard device indicating that the first onboard device is in a sleep-enabled state;
- determine, based on the network management transmitted from the first device, whether the first network is a target for cooperation control in which a network state is changed for the first network and the second network,
- transmit a request associated with a change of the network state to the second network when first data has been received from the first device and the first network is the target for the cooperation control, and
- not transmit the request associated with the change of the network state to the second network, but determine whether the onboard relay device is in a sleeping state when the first data has been received from the first device and the first network is not the target for the cooperation control, and
- wherein the second device is configured to change to a normal state or not to change to a sleeping state when the second device has received a request for prohibiting change to the sleeping state from the relay device after having transmitted data indicating that the second device is enabled to change to the sleeping state;
- wherein the first onboard device is not the second onboard device.
