Abstract

When a plurality of managing apparatuses which manage communication parameters exists, there is a case where the wrong communication parameters are set into a communicating apparatus. When the communication parameters are set between the managing apparatus which manages the communication parameters and the communicating apparatus, if a plurality of managing apparatuses in a setting state of the communication parameters into the communicating apparatus is detected, the managing apparatus in the setting state is notified that the plurality of managing apparatuses in the setting state exists. Whether or not the setting of the communication parameters is continued is discriminated, thereby continuing or stopping the setting of the communication parameters.

Claims

1. A method of sharing wireless communication parameters for wirelessly communicating with a base station, wherein the wireless communication parameters are shared between at least one managing apparatus for managing the wireless communication parameters and at least one communicating apparatus for wirelessly communicating with the base station using the wireless communication parameters, the method comprising:

a detecting step of detecting, at either one of a first communicating apparatus and a first managing apparatus, a managing apparatus, wherein said one of the first communicating apparatus and the first managing apparatus, and the managing apparatus, are operating in a setting mode,

wherein with respect to the first communicating apparatus, the setting mode is for receiving the wireless communication parameters from the managing apparatus, and wherein with respect to the first managing apparatus and the managing apparatus, the setting mode is for providing the wireless communication parameters to the communicating apparatus;

a comparing step of, if a plurality of managing apparatuses operating in the setting mode are detected in the detecting step, making, at the first managing apparatus, a comparison between the wireless communication parameters managed by the plurality of managing apparatuses operating in the setting mode, so as to obtain a comparison result; and

a controlling step of controlling processing by selectively continuing or stopping the setting mode in said one of the first communicating apparatus and the first managing apparatus according to whether or not the wireless communication parameters managed by the plurality of managing apparatuses operating in the setting mode are the same.

2. A method according to claim 1, further comprising a notifying step of notifying the plurality of managing apparatuses operating in the setting mode that the plurality of managing apparatuses operating in the setting mode exist, if the plurality of managing apparatuses operating in the setting mode are detected in the detecting step.

3. A method according to claim 1, further comprising a displaying step of displaying a message for urging a user to reset the setting mode, when the setting mode is stopped in the controlling step.

4. A method according to claim 3, wherein if the setting mode is set again, the providing and receiving of the wireless communication parameters is executed between one of the plurality of managing apparatuses operating in the setting mode which has been detected first and the first communicating apparatus.

5. A method according to claim 1, wherein the comparison in the comparing step is based on a signal transmitted from the base station.

6. A method according to claim 5, further comprising a selecting step of, selecting, from among the plurality of managing apparatuses operating in the setting mode, the managing apparatus for providing the wireless communication parameters to the first communicating apparatus based on a receiving state of the signal from the base station, when the plurality of managing apparatuses operating in the setting mode are detected in the detecting step.

7. A method according to claim 5, further comprising:

a deciding step of deciding whether or not the managing apparatus for providing the wireless communication parameters to the first communicating apparatus is to be selected based on a receiving state of the signal from the base station, when the plurality of managing apparatuses in the setting mode are detected in the detecting step; and

a notifying step of notifying the plurality of managing apparatuses operating in the setting mode that the plurality of managing apparatuses operating in the setting mode exist, according to the decision in the deciding step.

8. A method according to claim 6, wherein

the selecting step is executed in the first communicating apparatus, and

the method further comprises displaying a message for making the managing apparatus selected in the selecting step correspond to the first communicating apparatus which has selected the managing apparatus.

9. A managing apparatus, comprising:

a managing device that manages wireless communication parameters comprising at least one of an encrypting system, an encryption key, an authenticating system and an authentication key;

a detecting device that detects another managing apparatus that is operating in a setting mode for providing the wireless communication parameters to a communication apparatus, while the managing apparatus is operating in the setting mode;

a comparing device that compares the wireless communication parameters managed by the other managing apparatus operating in the setting mode detected by the detecting device and the wireless communication parameters managed by the managing device; and

a discriminating device that discriminates whether or not the setting mode of the managing apparatus is to be continued according to whether or not the wireless communication parameters managed by the managing device corresponds to the wireless communication parameters managed by the other managing apparatus.

10. A managing apparatus according to claim 9, further comprising

a notifying device that notifies a base station serving as a management target of the managing apparatus of a continuation of the setting mode or an end of the setting mode.

11. A managing apparatus according to claim 10, further comprising

a requesting device that requests the base station to change contents of a signal transmitted from the base station.

12. A managing apparatus according to claim 9, wherein the detecting device detects the other managing apparatus based on a notification from the communicating apparatus.

13. A managing apparatus according to claim 10, wherein the detecting device detects the other managing apparatus based on a signal from the base station.
