Abstract

A wireless communication apparatus includes a wireless communication unit configured to conduct wireless communication by selecting one wireless scheme among a plurality of wireless schemes capable of conducting wireless communication, a storage which stores information obtained by classifying the plurality of wireless schemes into a plurality of classes, based on priorities set to the plurality of wireless schemes in accordance with at least one parameter, and a selector which selects one wireless scheme by which the wireless communication unit conducts wireless communication, based on classes stored in the storage.

Claims

1. A wireless communication apparatus, comprising:

a wireless communication unit configured to conduct wireless communication by selecting one wireless scheme among a plurality of wireless schemes capable of conducting wireless communication;

a storage which stores information obtained by classifying said plurality of wireless schemes into a plurality of classes, based on priorities set to said plurality of wireless schemes in accordance with at least one parameter; and

a selector which selects one wireless scheme by which said wireless communication unit conducts wireless communication, based on classes stored in said storage.

2. The wireless communication apparatus according to claim 1, further comprising a classification unit configured to classify said plurality of wireless schemes into a plurality of classes, based on the priorities of said plurality of wireless schemes;

wherein said storage stores a result of classification by said classification unit.

3. The wireless communication apparatus according to claim 2, wherein said classification unit classifies said plurality of wireless schemes into a plurality of classes for each parameter;

and

said selector selects a wireless scheme to be used, based on the class set for each parameter.

4. The wireless communication apparatus according to claim 2, wherein said selector gives priority to each parameter, and selects the wireless scheme by which said wireless communication unit conducts the wireless communication, by preferentially taking into consideration the class corresponding to the parameter having higher priority.

5. The wireless communication apparatus according to claim 2, wherein said classification unit classifies said plurality of wireless schemes into said plurality of classes, based on degree of achievement for parameter.

6. The wireless communication apparatus according to claim 2, wherein said classification unit classifies said plurality of wireless schemes into said plurality of classes, based on at least one parameter for each communication type;

and

said selector selects the wireless scheme by which said wireless communication unit conducts wireless communication, based on the classes stored in said storage in accordance with each communication type.

7. The wireless communication apparatus according to claim 2, wherein classification unit classifies said plurality of wireless schemes into said plurality of classes, based on at least one parameter in accordance with ordinary time and time of user'"'"'s desire;

and

said selector selects the wireless scheme by which said wireless communication unit conducts the wireless communication, based on the classes stored in said storage in accordance with either the ordinary time or the time of user'"'"'s desire.

8. The wireless communication apparatus according to claim 2, wherein said classification unit classifies residual quantity in a battery into a plurality of stages, and classifies said plurality of wireless schemes into said plurality of classes based on at least one parameter for each of said plurality of stages.

9. The wireless communication apparatus according to claim 2, wherein said classification unit classifies said plurality of wireless schemes into said plurality of classes, based on at least one parameter at time of communication start and during communication;

and

said selector selects the wireless scheme by which said wireless communication unit conducts wireless communication, based on the classes stored in said storage either at the time of communication start or during communication.

10. The wireless communication apparatus according to claim 1, wherein said selector selects the other wireless scheme belonging to the same class as that of the selected wireless scheme when the selected wireless scheme cannot conduct the wireless communication.

11. The wireless communication apparatus according to claim 2, wherein said classification unit classifies said plurality of wireless schemes into a plurality of classes based on adaptation degrees indicative of degree of compatibility with respect to said plurality of wireless schemes;

and

said selector selects preferentially the wireless scheme belonging to the class having high adaptation degree when the wireless scheme for conducting the wireless communication is changed.

12. The wireless communication apparatus according to claim 1, further comprising a monitor unit configured to monitor at least one of operation states of the wireless schemes except for the wireless scheme selected by said selector and empty channel information of the other wireless schemes;

and

said selector continuously selects the wireless scheme being currently selected when said monitor unit detects that a wireless scheme having higher priority than that of the wireless scheme being currently selected becomes available and belongs to the same class as that of the wireless scheme being currently selected.

13. The wireless communication apparatus according to claim 1, further comprising:

a weight unit configured to add weights corresponding to the respective parameters for each of said wireless schemes; and

a weight adding unit configured to add the weights corresponding to the parameters for each of said wireless schemes,

wherein said selector selects the wireless scheme by which said wireless communication unit conducts the wireless communication, based on the classes classified by said classification unit and the weight added by said weight adding unit.

14. The wireless communication apparatus according to claim 1, wherein said selector changes over the wireless scheme by which said wireless communication unit conducts the wireless communication when the weight added by said weight adding unit becomes less than a prescribed reference value.

15. A wireless communication method, comprising:

conducting wireless communication by selecting one wireless scheme among a plurality of wireless schemes capable of conducting wireless communication;

classifying said plurality of wireless schemes based on priorities set to said plurality of wireless schemes in accordance with at least one parameter, and storing a result of the classification into a storage; and
