Abstract

The present invention provides a method of constructing a radio network which enables the user to select an arbitrary radio communication apparatus (A to E) as a control station and thus selected radio communication apparatus preferentially constructs the radio network, and a radio communication apparatus which is desired to be arranged as a control station is set up so that it has the function of preferentially becoming a control station in advance. In case some radio communication apparatuses are designated as control stations, any of the radio communication apparatuses is selected as a control station based on the number of radio communication apparatuses with which the designated radio communication apparatus can communicate.

Claims

1. A radio communication system using a radio network composed of a plurality of radio communication apparatuses each can work as a control station,

wherein each of the radio communication apparatuses has the function of cooperatively determining a control station of the radio network, and the radio communication apparatus which is designated as a control station by the user is preferentially selected as a control station.

2. The radio communication system as set forth in claim 1, wherein each of the plural radio communication apparatuses has a switch means for preferentially designating the radio communication apparatus as a control station of the radio network.

3. The radio communication system as set forth in claim 1, wherein, after interchange processing of control station selection information is performed at least second times, a control station is determined based on interchanged control station selection information.

4. The radio communication system as set forth in claim 1, wherein, in case some of the plural radio communication apparatuses are designated as control stations, any of the radio communication apparatuses designated as control stations is selected as a control station based on the number of radio communication apparatuses with which the designated radio communication apparatus can communicate.

5. A radio communication apparatus for a radio network, comprising the function of:

communicating with other radio communication apparatuses to interchange control station selection information; and

preferentially becoming a control station according to the settings of the user.

6. The radio communication apparatus as set forth in claim 5, wherein the radio communication apparatus has a switch means for preferentially designating the radio communication apparatus as a control station of the radio network.

7. A radio communication apparatus, comprising the function of:

constructing a radio network using a plurality of radio communication apparatuses;

communicating with other radio communication apparatuses to select a control station;

detecting a radio communication apparatus which preferentially becomes a control station; and

becoming a control station in case the number of radio communication apparatuses with which the radio communication apparatus can communicate is large.

8. A method of constructing a radio network composed of a plurality of radio communication apparatuses each can work as a control station, comprising the steps of;

accepting a designation as a control station from the user by any of the radio communication apparatuses

selecting any of the plural radio communication apparatuses as a control station;

wherein, in the selection step, the radio communication apparatus which is designated as a control station by the user is preferentially selected as a control station.

9. The method of constructing a radio network as set forth in claim 8, wherein each of the plural radio communication apparatuses has a switch means to preferentially become a control station of the radio network.

10. The method of constructing a radio network as set forth in claim 8, wherein, in the selection step, after interchange processing of control station selection information is performed at least second times, a control station is determined based on interchanged control station selection information.

11. The method of constructing a radio network as set forth in claim 8, wherein, in case some of the plural radio communication apparatuses are designated as control stations, any of the radio communication apparatuses designated as control stations is selected as a control station based on the number of radio communication apparatuses with which the designated radio communication apparatus can communicate.

12. A method of constructing a radio network composed of a plurality of radio communication apparatuses, comprising the steps of;

transmitting information for selecting a control station;

obtaining the number of radio communication apparatuses to which each of the radio communication apparatuses can make a connection.

selecting any of the plural radio communication apparatuses as a control station.

13. The method of constructing a radio network as set forth in claim 12, wherein information for selecting a control station is transmitted at least two times.
