[Solution] A device includes: a processing unit configured to notify an access point of a message used to instruct the access point to establish a connection for infrastructure communication with another device on condition that a connection for P2P communication with the other device is established, a connection for infrastructure communication with the access point is established or there is a history in which the connection has been established, and a connection for infrastructure communication between the other device and the access point is not established. ## Claims ### Claim 1 A device comprising: a processing unit configured to notify an access point of a message used to instruct the access point to establish a connection for infrastructure communication with another device on condition that a connection for P2P communication with the other device is established, a connection for infrastructure communication with the access point is established or there is a history in which the connection has been established, and a connection for infrastructure communication between the other device and the access point is not established. ### Claim 2 (depends on 1) The device according to claim 1, wherein the processing unit notifies the other device of configuration information used for the connection with the access point, by using P2P communication. ### Claim 3 (depends on 2) The device according to claim 2, wherein the configuration information includes at least any of a service set identifier (SSID), a basic service set identifier (BSSID), a media access control (MAC) address, port information, or a device name (DevName) of the access point. ### Claim 4 (depends on 2) The device according to claim 2, wherein the processing unit notifies the access point of a message used to request the access point to accept the notification of the configuration information to the other device. ### Claim 5 (depends on 1) The device according to claim 1, wherein the processing unit notifies the other device of a message used to instruct the other device to establish the connection for infrastructure communication with the access point, by using P2P communication. ### Claim 6 (depends on 5) The device according to claim 5, wherein the other device displays information relating to the connection for infrastructure communication by using reception of the message used to instruct to establish the connection for infrastructure communication with the access point as a trigger. ### Claim 7 (depends on 1) The device according to claim 1, wherein the processing unit notifies the access point of information for identifying the other device. ### Claim 8 (depends on 7) The device according to claim 7, wherein the information for identifying the other device is a MAC address of the other device. ### Claim 9 (depends on 1) The device according to claim 1, wherein the P2P communication is Wi-Fi Direct (registered trademark) or neighborhood area network (NAN) compliant communication. ### Claim 10 (depends on 1) The device according to claim 1, wherein the infrastructure communication is Wi-Fi (registered trademark) compliant communication. ### Claim 11 A device comprising: a processing unit configured to start processing for establishing a connection for infrastructure communication with a second terminal device by using reception of a notification of a message from a first terminal device as a trigger, the message being used to instruct to start the connection for infrastructure communication with the second terminal device and being notified from the first terminal device in which a connection for infrastructure communication with its own device is established or there is a history in which the connection has been established and a connection for P2P communication with the second terminal device is established. ### Claim 12 (depends on 11) The device according to claim 11, wherein the processing unit notifies the second terminal device of a message used to instruct the second terminal device to start a connection for infrastructure communication with the first terminal device. ### Claim 13 (depends on 12) The device according to claim 12, wherein the processing unit broadcasts a beacon including information indicative of being operated in a push button configuration (PBC) mode. ### Claim 14 (depends on 12) The device according to claim 12, wherein the processing unit broadcasts a beacon including information used to instruct to switch from P2P communication to infrastructure communication. ### Claim 15 (depends on 11) The device according to claim 11, wherein the processing unit identifies a probe request notified from the second terminal device among one or more notified probe requests by using information for identifying the second terminal device, the information being notified from the first terminal device. ### Claim 16 (depends on 11) The device according to claim 11, wherein the processing unit notifies the first terminal device of a message indicating whether to accept a notification of configuration information used for a connection for infrastructure communication with its own device to the second terminal device. ### Claim 17 (depends on 11) The device according to claim 11, wherein the processing unit notifies the first terminal device of a message indicating whether to accept concurrent connection for infrastructure communication between its own device and the first terminal device and P2P communication between the first terminal device and the second terminal device. ### Claim 18 A device comprising: a processing unit configured to notify another device of configuration information used for a connection for P2P communication with the other device by using infrastructure communication via an access point on condition that a connection for infrastructure communication with the access point is established and a connection for infrastructure communication between another terminal and the access point is established. ### Claim 19 (depends on 18) The device according to claim 18, wherein the configuration information includes at least any of a service set identifier (SSID), a basic service set identifier (BSSID), a media access control (MAC) address, port information, a device name (DevName), or a group ID of the device. ### Claim 20 A method comprising: notifying, by a processor, an access point of a message used to instruct the access point to establish a connection for infrastructure communication with another device, on condition that a connection for P2P communication with the other device is established, a connection for infrastructure communication with the access point is established or there is a history in which the connection has been established, and a connection for infrastructure communication between the other device and the access point is not established.
