Abstract

When a communication parameter provided from a communication device is received in a communication parameter automatic setting process, it is determined whether the number of characters in the communication parameter is a predetermined number, whether the communication parameter includes a predetermined character, or whether the communication parameter is a communication parameter use of which is prohibited in a certain region. In accordance with a determination result, control is performed so that the communication parameter is not used.

Claims

1. A communication device comprising:

a receiving unit configured to receive a communication parameter provided from another communication device in a communication parameter automatic setting process;

a determining unit configured to determine whether the number of characters in the communication parameter received by the receiving unit is a predetermined number or whether the communication parameter includes a predetermined character; and

a control unit configured to perform control so that the communication parameter is not used for communication if the determining unit determines that the number of characters in the communication parameter is not the predetermined number or that the communication parameter includes the predetermined character.

3. The communication device according to claim 1, wherein the determining unit determines whether the number of characters in the received communication parameter is the number of characters specified by a wireless LAN standard of the 802.11 series or whether the received communication parameter includes a character other than characters specified by the wireless LAN standard of the 802.11 series.

4. The communication device according to claim 1, wherein the determining unit determines whether the received communication parameter includes a control character.

5. The communication device according to claim 1, wherein the determining unit determines whether the received communication parameter includes Hiragana or Kanji.

7. The communication device according to any one of claims 1 to 6, wherein the control unit notifies the other communication device of an error.

8. The communication device according to any one of claims 1 to 7, wherein the control unit requests the other communication device to newly provide a communication parameter different from the received communication parameter.

9. The communication device according to any one of claims 1 to 8, wherein the control unit notifies a user of an error.

10. The communication device according to any one of claims 1 to 9, wherein the control unit performs notification to prompt a user to set a communication parameter in a method different from the automatic setting process.

11. The communication device according to any one of claims 1 to 9, wherein the control unit automatically starts a process of setting a communication parameter in a method different from the automatic setting process.

2. A communication device comprising:

a receiving unit configured to receive a communication parameter provided from another communication device in a communication parameter automatic setting process;

a determining unit configured to determine whether the communication parameter received by the receiving unit is a communication parameter use of which is prohibited in a certain region; and

a control unit configured to perform control so that the communication parameter is not used if the determining unit determines that the communication parameter is the communication parameter use of which is prohibited in the certain region.

6. The communication device according to claim 2, wherein the determining unit determines whether the received communication parameter is a communication parameter use of which is prohibited by a law in the certain region.

12. A communication device comprising:

a receiving unit configured to receive a communication parameter including a frequency channel from another communication device;

a determining unit configured to determine whether the frequency channel included in the communication parameter received by the receiving unit is a frequency channel use of which is limited among a plurality of frequency channels used for communication; and

a control unit configured to perform control so that the frequency channel included in the communication parameter is not used if the determining unit determines that the frequency channel included in the communication parameter is the frequency channel use of which is limited.

13. A method for controlling a communication device, comprising:

a receiving step of receiving a communication parameter provided from another communication device in a communication parameter automatic setting process;

a determining step of determining whether the number of characters in the communication parameter received in the receiving step is a predetermined number or whether the communication parameter includes a predetermined character; and

a control step of performing control so that the communication parameter is not used for communication if the determining step determines that the number of characters in the communication parameter is not the predetermined number or that the communication parameter includes the predetermined character.

16. A program causing a computer to execute the respective steps in the method according to any one of claims 13 to 15.

14. A method for controlling a communication device, comprising:

a receiving step of receiving a communication parameter provided from another communication device in a communication parameter automatic setting process;

a determining step of determining whether the communication parameter received in the receiving step is a communication parameter use of which is prohibited in a certain region; and

a control step of performing control so that the communication parameter is not used if the determining step determines that the communication parameter is the communication parameter use of which is prohibited in the certain region.

15. A method for controlling a communication device, comprising:

a receiving step of receiving a communication parameter including a frequency channel from another communication device;

a determining step of determining whether the frequency channel included in the communication parameter received in the receiving step is a frequency channel use of which is limited among a plurality of frequency channels used for communication; and

a control step of performing control so that the frequency channel included in the communication parameter is not used if the determining step determines that the frequency channel included in the communication parameter is the frequency channel use of which is limited.
