Abstract

An accounting system and method are incorporated into a data communication network conducted by a information provider which includes a central computer for data communication with a user computer. Download data, such as route guidance data, is transmitted from the central computer of the information provider to the user computer, whereas the upload data which is available to enrich a database in the central computer is transmitted from the user computer to the central computer. The central computer determines accounts payable by the user in accordance with the content and/or volume of the download data. It also determines a reward for the user in accordance with the content and/or volume of the upload data. An amount that is a balance obtained by subtracting the reward from the accounts receivable is charged to the user. Therefore, the more upload data sent by the user to the central computer and the more it is utilized, the more the user'"'"'s expense for the service provided by the information provider is reduced.

Claims

1. An accounting system in a data communication network, comprising:

a central computer for data communication with a user computer of a user;

receiving means for receiving upload data transmitted from the user computer to the central computer;

download data generating means for generating download data with reference to the received upload data;

transmitting means for transmitting the download data from the central computer to the user computer;

account calculating means for calculating accounts payable by the user depending upon content and/or volume of the download data transmitted from the central computer to the user computer;

reward calculating means for calculating a reward for the user depending upon the content and/or volume of the upload data transmitted from the user computer; and

billing means for billing the user an amount obtained by subtracting the reward from the accounts payable.

2. An accounting system in accordance with

claim 1

, wherein the upload data is transmitted from the user computer by manual operation of the user.

3. An accounting system in accordance with

claim 1

, wherein the user computer includes available information collecting means for collecting available information of potential use to other users, the upload data being automatically transmitted from the user computer in response to an output from the available information collecting means.

4. An accounting system in accordance with

claim 1

, wherein the reward calculating means calculates the reward with reference to a history of use of the upload data, transmitted from the user computer, in operation of the central computer.

5. An accounting system in accordance with

claim 4

, wherein the history of use of the upload data is calculated based on the number of times the upload data is referenced by the download data generating means.

6. An accounting system in a data communication network for a vehicle navigation system, comprising:

a central computer, having a road/map database, for data communication with a user computer of a user;

route guidance data generating means for generating data for route guidance from a current position of the user to a destination by retrieval of road/map data from the road/map database;

transmitting means for transmitting the route guidance data from the central computer to the user computer;

account calculating means for calculating accounts payable by the user in accordance with content and/or volume of the route guidance data transmitted from the central computer to the user computer;

receiving means, at the central computer, for receiving traffic information from the user computer, wherein the received traffic information is referenced in generating the route guidance data by the route guidance data generating means;

reward calculating means for calculating a reward for the user depending upon content and/or volume of the traffic information transmitted from the user computer; and

billing means for billing the user an amount obtained by subtracting the reward from the accounts payable.

7. An accounting system in accordance with

claim 6

, wherein the traffic information consists at least one of:

information indicating time and area of a traffic jam;

information indicating a traffic jam has abated;

information indicating time and area of a traffic accident;

information indicating a traffic accident has been removed; and

information regarding roads not contained in the road/map database in the central computer.

8. An accounting system in accordance with

claim 6

, wherein the traffic information is transmitted from the user computer by manual operation of the user.

9. An accounting system in accordance with

claim 6

, wherein the user computer has traffic information collecting means for collecting traffic information, the traffic information being automatically transmitted from the user computer in response to an output from the traffic information collecting means.

10. An accounting system in accordance with

claim 6

, wherein the reward calculating means calculates the reward with reference to a history of using the traffic information, transmitted from the user computer, in operation of the central computer.

11. An accounting system in accordance with

claim 10

, wherein the history of using the traffic information is calculated based on the number of times the traffic information is referenced by the route guidance data generating means for generating the route guidance data.

12. An accounting method for use in a data communication network wherein an information provider communicates with a user computer, comprising the steps of:

receiving upload data transmitted from the user computer to the information provider;

generating download data by making reference to the received upload data;

transmitting the download data from the information provider to the user computer;

calculating accounts payable by the user in accordance with content and/or volume of the download data;

calculating a reward for the user in accordance with the content and/or volume of the upload data; and

billing the user an amount obtained by subtracting the reward from the accounts payable.

13. An accounting method in accordance with

claim 12

, wherein the upload data is transmitted from the user computer by manual operation of the user.

14. An accounting method in accordance with

claim 12

, further comprising collecting available information, by available information collecting means of the user computer, which is usable by other users, and automatically transmitting the upload data from the user computer in response to an output from the available information collecting means.

15. An accounting method in accordance with

claim 12

, wherein the reward is calculated with reference to a history of use of the upload data by the information provider.

16. An accounting method in accordance with

claim 15

, wherein the history of use of the upload data is calculated based on the number of times the upload data is referenced in generating the download data.

17. An accounting method in a data communication network for a vehicle navigation system, wherein an information provider, having a road/map database, communicates with a user computer, comprising:

generating route guidance data for guidance from a current position of the user to a destination, with retrieval of road/map data from the road/map database;

transmitting the route guidance data from the information provider to the user computer;

calculating accounts payable by the user in accordance with content and/or volume of the route guidance data transmitted from the information provider to the user computer;

receiving traffic information from the user computer wherein the received traffic information is referenced in generating the route guidance data;

calculating a reward for the user in accordance with content and/or volume of the traffic information transmitted from the user computer; and

billing the user an amount obtained by subtracting the reward from the accounts payable.

18. An accounting method in accordance with
