2. A personal digital assistant device according to claim 1, wherein the use information includes positional information of said personal digital assistant device.

3. A personal digital assistant device according to claim 1, wherein said sending means sends use information requested by said service information distribution device to be sent.

4. A personal digital assistant device according to claim 1, further comprising display means for displaying the service information received by said receiving means.

5. A service information distribution device for distributing service information to a personal digital assistant device, comprising:

receiving means for receiving use information of a user intermittently from said personal digital assistant device;

storing means for storing the received use information in a history database as history data;

selection means for selecting service information to be distributed to said personal digital assistant device on the basis of the use information stored in said history database; and

distribution means for distributing the service information selected by said selection means to said personal digital assistant device.

6. A service information distribution device according to claim 5, wherein the use information includes positional information of said personal digital assistant device.

7. A service information distribution device according to claim 6, wherein said selection means selects service information regarding a zone by discriminating the zone having high frequency of dropby on the basis of the history data regarding the positional information.

8. A service information distribution device according to claim 5, wherein the service information includes congestion degree information.

9. A service information distribution device according to claim 5, wherein the service information includes at least one of informations regarding sale of an article, advertisement distribution, reservation, hall guidance, opening of an event and an attraction, suitable for said personal digital assistant device.

10. A service information distribution device according to claim 6, wherein said distribution means distributes the selected service information in response to request from said personal digital assistant device.

11. A service information distribution device according to claim 10, wherein said distribution means distributes selected positional information of another personal digital assistant device in response to request regarding positional information of said another personal digital assistant device from said personal digital assistant device.

12. A service information distribution device according to claim 5, wherein said history database also stores accounting information for the user.

14. A control method according to claim 13, wherein the use information includes positional information of said personal digital assistant device.

15. A control method according to claim 13, wherein said sending step sends use information requested by said service information distribution device to be sent.

16. A control method according to claim 13, further comprising a displaying step for displaying the service information received by said receiving step.

18. A control method according to claim 17, wherein the use information includes positional information of said personal digital assistant device.

19. A control method according to claim 18, wherein said selecting step selects service information regarding a zone by discriminating the zone having high frequency of dropby on the basis of the history data regarding the positional information.

20. A control method according to claim 17, wherein the service information includes congestion degree information.

21. A control method according to claim 17, wherein the service information includes at least one of informations regarding sale of an article, advertisement distribution, reservation, hall guidance, opening of an event and an attraction, suitable for said personal digital assistant device.

22. A control method according to claim 17, wherein said distributing step distributes the selected service information in response to request from said personal digital assistant device.

23. A control method according to claim 22, wherein said distributing step distributes selected positional information of another personal digital assistant device in response to request regarding positional information of said another personal digital assistant device from said personal digital assistant device.

24. A control method according to claim 17, wherein said history database also stores accounting information for the user.

13. A control method for controlling a personal digital assistant device for receiving service information from a service information distribution device, comprising:

a sending step for sending use information of a user using said personal digital assistant device intermittently to be added to a history database managed by said service information distribution device; and
