Abstract

A communicating apparatus receives a request command which requires a response, and determines whether the communication mode of a partner apparatus corresponding to the request command matches a communication mode executed by the self communicating apparatus. If it is determined that the communication mode of the partner apparatus matches the communication mode executed by the self communicating apparatus, the communicating apparatus transmits a response command to the request command. If it is determined that the communication mode of the partner apparatus does not match the communication mode executed by the self communicating apparatus, the communicating apparatus transmits no response command to the request command.

First claim

What is claimed is:

1. A communicating apparatus having an image forming unit comprising;
a reception unit configured to receive a request command which requires a response, wherein a partner apparatus transmits the request command;
a determination unit configured to determine based on the request command received by said reception unit whether a communication mode of the partner apparatus matches a communication mode executed by said communicating apparatus; and
a response control unit configured to generate, in a case where the determination unit determines that the communication mode of the partner apparatus matches the communication mode of the communicating apparatus, a response command corresponding to the request command from the partner apparatus, wherein
the response control unit, in a case where the determination unit determines that the communication mode of the partner apparatus does not match the communication mode of the communicating apparatus, does not generate the response command corresponding to the request command from the partner apparatus, and
one or more of the reception unit, the determination unit, or the response control unit is implemented by a processor and a memory.

2. The apparatus according to claim 1 , wherein said determination unit refers to presence/absence of a predetermined attribute added to the request command, and determines whether the communication mode of the partner apparatus matches the communication mode executed by said communicating apparatus.

3. The apparatus according to claim 2 , wherein in a case where the request command is added with an attribute unnecessary for the communication mode executed by said communicating apparatus, said determination unit determines that the communication mode of the partner apparatus does not match the communication mode executed by said communicating apparatus.

4. The apparatus according to claim 1 , wherein
after said response control unit transmits the response command, in a case where said reception unit receives a request command from the partner apparatus which has received the response command,
said response control unit transmits a response command irrespective of determination by said determination unit.

5. The apparatus according to claim 1 , wherein the request command is a command for searching for an apparatus to be wirelessly connected.

6. The apparatus according to claim 1 , wherein the communication mode includes a mode for performing peer-to-peer wireless connection.

7. The apparatus according to claim 1 , further comprising:
a storage unit configured to, in a case where the determination unit determines that the communication mode of the partner apparatus matches the communication mode executed by the communicating apparatus, store information of the partner apparatus corresponding to the response command that has been transmitted by the response control unit; and
an information determination unit configured to, in a case where the determination unit determines that the communication mode of the partner apparatus does not match the communication mode executed by the communicating apparatus, determine whether or not information of the partner apparatus is stored in the storage unit, wherein
in a case where the information determination unit determines that the information of the partner apparatus is stored in the storage unit, the response control unit transmits the response command to the request command corresponding to the partner apparatus.

8. The apparatus according to claim 1 , wherein the image forming unit has a printing function to execute printing process.

9. The apparatus according to claim 1 , wherein the communication mode is a Wi-Fi Direct extended mode which is different from a Wi-Fi Direct mode.

10. The apparatus according to claim 9 , wherein an attribute of the Wi-Fi Direct extended mode is different from an attribute of the Wi-Fi Direct mode.

11. A communication method which is executed between a first communicating apparatus and a second communicating apparatus having an image forming unit, comprising:
in the first communicating apparatus, transmitting a request command which requires a response;
in the second communicating apparatus, receiving the request,
determining based on the request command whether a communication mode of the second communicating apparatus matches a communication mode executed by the first communicating apparatus, and
transmitting, in case where it is determined that the communication mode of the second communicating apparatus matches the communication mode of the first communicating apparatus, a response command corresponding to the request command to the second communicating apparatus, wherein in a case where it is determined that the communication mode of the second communicating apparatus does not match the communication mode of the first communicating apparatus, the response command corresponding to the request command is not transmitted to the second communicating apparatus, one or more of the reception unit, the determination unit, or the response control unit being implemented by a processor and a memory; and
in the first communicating apparatus,
determining based on the response command whether the communication mode of the first communicating apparatus matches the communication mode executed by the second communicating apparatus, and
deciding the second communicating apparatus as a communicable apparatus, in a case where it is determined that the communication mode of the first communicating apparatus matches the communication mode executed by the second communicating apparatus.

12. A non-transitory computer-readable storage medium storing a program for causing a computer to execute
receiving a request command which requires a response, wherein a partner apparatus transmits the request command;
determining based on the received request command whether a communication mode of the partner apparatus matches a communication mode executed by the computer; and
transmitting, in a case where it is determined that the communication mode of the partner apparatus matches the communication mode of the communicating apparatus, a response command corresponding to the request command to the partner apparatus, wherein in a case where it is determined that the communication mode of the partner apparatus does not match the communication mode of the communicating apparatus, a response command to the request command is not transmitted to the partner apparatus, one or more of the reception unit, the determination unit, or the response control unit being implemented by a processor and a memory.
