Abstract

An information system includes a first terminal which is used by an information supplier to enter information about a state around a present location of the information supplier, a second terminal which is used by an information requester who wants to obtain the information entered by the information supplier, and a server which is connected to the first terminal and the second terminal and controls transmission of information between the terminals. In response to a request of the information requester, the second terminal displays a list of the information suppliers who can supply information about a location designated by the requester. The requester selects an information supplier from the list and then the server transmits the information supplied from the information supplier using the first terminal to the first terminal.

7. The information system of claim 6, wherein the first terminal consists of a mobile terminal having an information input function and a communication device which is separated from the mobile terminal.

8. The information system of claim 1, wherein the server controls to directly connect the first terminal to the second terminal.

9. The information system of claim 8, wherein the first terminal is a mobile terminal having a communication function and the connection between the first terminal and the second terminal is made via a mobile phone network.

10. The information system of claim 9, wherein the first terminal consists of a mobile terminal having an information input function and a communication device which is separated from the mobile terminal.

11. The information system of claim 2 further comprising a charge/payment operating unit which charges the information requester a fee according to a connection time between the first terminal and the second time or the information supplied from the first terminal to the second terminal.

12. The information system of claim 11, wherein the charge/payment operating unit controls to pay at least a part of the fee paid by the information requester to the information supplier based on a predetermined fee for supplying information.

13. The information system of claim 12, wherein if the first terminal is a mobile phone or a terminal connected to a mobile phone, the charge/payment operating unit controls to charge the information requester a fee including a mobile phone network fee and to pay the mobile phone network fee to the corresponding mobile phone company.

14. The information system of claim 2, wherein when the information related to the present location of the information supplier is sent from the first terminal to the second terminal, the information is grouped into a plurality of areas and displayed on a display device of the second terminal.

16. The method of claim 15, wherein when the second terminal and the first terminal and the second terminal are connected each other, information related to the present location of the information supplier is sent from the first terminal to the second terminal.

17. The method of claim 15, wherein the information related to the present location of the information supplier represents a situation around the present location.

18. The method of claim 15, wherein the information related to the present location of the information supplier includes at least one type of data selected from a group including a moving picture, a still image, a sound, and characters.

15. A method of supplying information performed at an information system including a first terminal of an information supplier, a second terminal of an information requester, and a server connected to the first terminal and the first terminal, comprising the steps of:

generating, at the server, a list of information suppliers by referring to stored information supplier information including identifiers of the information suppliers and present locations of the information suppliers;

sending, at the server, the list of the information suppliers to the second terminal in response to a request of the information requester;

displaying, at the second terminal, the list of the information suppliers and making the information requester possible to select one of the information suppliers from the list; and

controlling, at the server, to connect the first terminal corresponding to the selected information supplier and the second terminal of the information requester.

19. A terminal of an information supplier included in an information system including a terminal of an information requester and a server connected to the terminals, comprising:

an input unit which inputs information related to a present location of the information supplier;

a notifying unit which notifies the server of identifier of the information supplier and the present location of the information supplier, at a predetermined timing; and

a transmission unit which transmits the information related to the present location to the terminal of the information requester in response to a request of the information requester.

20. A terminal of an information requester included in an information system including a terminal of an information supplier and a server connected to the terminals, comprising:
