Abstract

A public wireless LAN accessible area collection system includes a mobile terminal device having GPS means, wireless LAN communication means, and data communication means and a server which has storage means and accessible area map generation means and performs data communication with the mobile terminal device. When the wireless LAN communication means recognizes that the mobile terminal device exists in the area in which the mobile terminal device can be connected to the public wireless LAN, it obtains access information in the area. The data communication means transmits location information and access information to the server. The server associates the location information with the access information that are received from the mobile terminal device and stores them in the storage means. The accessible area map generation means applies the location information about the area in which the mobile terminal device can be connected to the public wireless LAN to the map data according to the location information stored in the storage means.

Claims

1. An information collection system comprising:

a mobile terminal device having location information obtaining means for obtaining location information of a mobile terminal device, and data communication means for transmitting various types of obtained information to an information registration server; and

an information registration server provided with storage means for storing various types of information received from the mobile terminal device;

said information collection system characterized in that

said mobile terminal device comprises wireless LAN communication means for accessing a wireless LAN and obtaining access information of the wireless LAN;

said data communication means transmits location information of the time at which said wireless LAN was accessed that is obtained by said location information obtaining means, and access information obtained by said wireless LAN communication means to said information registration server; and

said information registration server associates and stores in said storage means the access information and the location information received from said mobile terminal device.

2. The information collection system according to claim 1, characterized in that said access information is an SSID (service set identifier) of an access point of the wireless LAN.

3. The information collection system according to claim 1, characterized in that said access information is a MAC address (media access control address) of an access point of the wireless LAN.

4. The information collection system according to claim 1, characterized in that

said information registration server comprises accessible area map generation means;

and

said accessible area map generation means causes location information of an area in which connection to said wireless LAN is possible to be reflected in map data on the basis of the location information and access information stored in said storage means.

5. The information collection system according to claim 4, characterized in that

said access information includes communication protocol information;

and

said accessible area map generation means changes the manner of reflection in said map data according to the type of said communication protocol.

6. The information collection system according to claim 4, characterized in that

said access information includes reception quality information;

and

said accessible area map generation means changes the manner of reflection in said map data according to said reception quality.

7. The information collection system according to claim 4, characterized in that

said access information includes inherent information of an access point in an area to which said wireless LAN can be connected;

and

said accessible area map generation means causes an area to which said wireless LAN can be connected that has the same inherent information to be reflected in said map data as belonging to the same area.

8. The information collection system according to any of claims 1 through 7, characterized in that said information registration server deletes already-stored access information when access information having the same location information as access information already stored in said storage means is not received from said mobile terminal device within a predetermined period of time.

9. The information collection system according to any of claims 1 through 7, characterized in that when information of a plurality of locations is associated with the same access information stored in said storage means, said information registration server computes representative location information from said plurality of location information and stores the representative location information in said storage means.

10. The information collection system according to claim 1, characterized in that

said information registration server comprises location identification means;

and

when a query including said access information is received, said location identification means recalls location information associated with said access information from said storage means and responds.

11. The information collection system according to claim 10, characterized in that when information of a plurality of locations is associated with said access information, said location identification means computes representative location information from said plurality of location information and responds.

12. An information registration server comprising storage means for storing various types of information received from a mobile terminal device having location information obtaining means for obtaining location information of a mobile terminal device, wireless LAN communication means for accessing a wireless LAN and obtaining access information of the wireless LAN, and data communication means for transmitting various types of obtained information to an information registration server;

said information registration server characterized in that

location information of the time said wireless LAN was accessed that is obtained by said location information obtaining means and transmitted by said data communication means is associated with access information obtained by said wireless LAN communication means and stored in said storage means by said information registration server.

13. The information registration server according to claim 12, characterized in that when information of a plurality of locations is associated with the same access information stored in said storage means, said information registration server computes representative location information from said plurality of location information and stores the representative location information in said storage means.

14. The information registration server according to claim 12 or 13, characterized in that

said information registration server comprises location identification means;

and

when a query including said access information is received, said location identification means recalls location information associated with said access information from said storage means and responds.

15. An information collection method in an information collection system that comprises a mobile terminal device having location information obtaining means for obtaining location information of a mobile terminal device, and data communication means for transmitting various types of obtained information to an information registration server;

and

an information registration server provided with storage means for storing various types of information received from the mobile terminal device;

said information collection method characterized in that
