Abstract

A communication device capable of handling, even in the case where requests for provision of a service are received from a plurality of devices, the requests appropriately, is provided.

A communication device which provides a service to a service utilizing device which utilizes a service, determines whether or not the communication device is executing a service requested from the service utilizing device. In the case where it is determined that the communication device is executing the service, the communication device makes a response to the request with the contents of the response changed according to whether or not the service is able to be provided to a plurality of service utilizing devices.

Claims

1. A communication device capable of wireless communication, comprising:

a processor; and

a memory coupled to the processor having instructions that, when executed by the processor, cause the processor to perform operations comprising;

wirelessly connecting the communication device to a first other communication device, the communication device operating as a device which establishes a wireless network or as a device which takes part in an established wireless network;

receiving a request for print processing using wireless communication from a second other communication device different from the first other communication device, while the communication device is connected to the first other communication device;

determining whether print processing is being performed with the first other communication device in a case where the request for the print processing is received; and

determining whether the communication device is operating as a device which establishes a wireless network or as a device which takes part in an established wireless network; and

transmitting a response indicating that print processing is performable to the received request in a case where the first determination determines that the print processing is not being performed or in a case where the second determination determines that the communication device is operating as a device which establishes a wireless network, and not transmitting a response indicating that print processing is performable to the received request in a case where the first determination determines that the print processing is being performed and the second determination determines that the communication device is operating as a device which takes part in an established wireless network.

2. The communication device according to claim 1, wherein the second determination determines whether the communication device is operating as a device which establishes a wireless network or as a device which takes part in an established wireless network in a case where the first determination determines that the print processing is being performed.

3. The communication device according to claim 1, wherein transmitting transmits an error response to the received request in a case where the communication device does not support a function for performing print processing.

4. The communication device according to claim 1, wherein transmitting transmits an error response to the received request in a case where the first determination determines that the print processing is being performed and the second determination determines that the communication device is operating as a device which takes part in an established wireless network.

5. The communication device according to claim 1, wherein the received request is a service search signal.

6. The communication device according to claim 1, wherein a role as a device which establishes a wireless network is a P2P Group Owner in Wi-Fi Direct standard and a role as a device which takes part in an established wireless network is a P2P Client in the Wi-Fi Direct standard.

8. A non-transitory storage medium containing a program for causing a computer to operate as the communication device according to claim 1.

7. A control method for a communication device capable of wireless communication, the method comprising:

wirelessly connecting the communication device to a first other communication device, the communication device operating as a device which establishes a wireless network or as a device which takes part in an established wireless network;

receiving a request for print processing using wireless communication from a second other communication device different from the first other communication device, while the communication device is connected to the first other communication device;

performing a first determination of determining whether print processing is being performed with the first other communication device in a case where the request for the print processing is received; and

performing a second determination of determining whether the communication device is operating as a device which establishes a wireless network or as a device which takes part in an established wireless network; and

transmitting a response indicating that print processing is performable to the request received by the receiving step in a case where the first determination determines that the print processing is not being performed or in a case where the second determination determines that the communication device is operating as a device which establishes a wireless network, and not transmitting a response indicating that print processing is performable to the received request in a case where the first determination determines that the print processing is being performed and the second determination determines that the communication device is operating as a device which takes part in an established wireless network.
