Abstract

To provide an information supply system that supplies desired information to service subscribers, capable of automatically selecting and supplying information required by the user from whole information. Local servers 4 to 6 are provided with user DB 8 to 10 that store reception settings set by individual service subscribers. When service subscriber terminal moves to a service area of an access point connected, a local server establishes a channel with the service subscriber terminal, and references the corresponding reception setting from a user DB and only presents the message that matches the reception setting from message data stored in the local server to the service subscriber terminal.

Claims

1. An information supply system that has at least one local server means having a service area with a predetermined range and a central server means for connecting between said local server means and supplies pre-stored information to a service subscriber terminal existing in said service area, comprising:

information database means for storing information with each of which a transmission destination specification condition is associated;

subscriber database means for storing an information reception condition set for each of said service subscriber terminals;

information selecting means for comparing said information reception condition corresponding to said service subscriber terminal existing in the service area of said local server means with said transmission destination specification condition using said information database means and said subscriber database means and selecting only information having said transmission destination specification condition that satisfies said information reception condition; and

information supplying means for presenting only the information selected by said information selecting means to said service subscriber terminal existing in said service area.

2. The information supply system according to claim 1, wherein said information database means, said information selecting means and said information supplying means are provided in each of said local server means.

3. The information supply system according to claim 1, wherein said transmission destination specification condition includes at least one of location specification conditions that specify the local server means as the transmission destination, period specification conditions that specify the period for supplying information and information reception condition specification conditions that specify at least a value of said information reception conditions.

4. The information supply system according to claim 1, wherein said local server means further comprising:

subscriber terminal detecting means for detecting that said service subscriber terminal has moved to the own service area; and

channel controlling means for establishing a radio channel with said service subscriber terminal that has moved and informing said information selecting means of the establishment of the radio channel.

5. The information supply system according to claim 1,

wherein a push condition to specify whether auto distribution is available or not is specified for each piece of information stored in said information database means, and

said information supplying means automatically transmits the information for which said push condition specifies that auto distribution is available from among the information pieces selected by said information selecting means to said service subscriber terminal existing in said service area.

6. The information supply system according to claim 1, wherein said information supplying means further supplies broadcast data virtually consecutively supplied to said service subscriber terminal as said information.

7. The information supply system according to claim 1, wherein said information supplying means presents said information in response to information request from said service subscriber terminal existing in said service area.

8. The information supply system according to claim 1, wherein said central server means distributes the relevant reception information to necessary local server means based on said transmission destination specification condition of the information received from each of said local server means.

9. A control method of information supply system which includes at least one local server means having a service area with a predetermined range and a central server means to connect between said local server means, information database means for storing information with which transmission destination specification conditions are associated and subscriber database means for storing information reception conditions set for each of service subscriber terminals and which supplies pre-stored information to said service subscriber terminal existing in said service area, comprising:

an information selecting step of comparing said information reception condition corresponding to said service subscriber terminal existing in the service area of said local server means with said information transmission destination specification condition using said information database means and said subscriber database means and selecting only information having said transmission destination specification condition that satisfies said information reception condition; and

an information supplying step of presenting only the information selected by said information selecting step to said service subscriber terminal existing in said service area.

10. The information supply system control method according to claim 9, wherein both said information selecting step and said information supplying step are executed by said local server means.

11. The information supply system control method according to claim 9, wherein said transmission destination specification condition includes at least one of location specification conditions for specifying the local server means as the transmission destination, period specification conditions for specifying the period of supplying information and information reception condition specification conditions for specifying at least some values of said information reception conditions.

12. The information supply system control method according to claim 9, further comprising:

a subscriber terminal detecting step, performed at said local server means, of detecting that said service subscriber terminal has moved to its own service area; and

a channel control step, performed at said local server means, of establishing a radio channel with said service subscriber terminal that has moved and notifying the information to said information selecting step.

13. The information supply system control method according to claim 9,

wherein a push condition for specifying whether auto distribution is available or not is specified for each piece of information stored in said information database means, and

said information supplying step automatically transmits the information for which said push condition specifies that auto distribution is available from among the information pieces selected by said information selecting step to said service subscriber terminal existing in said service area.

14. The information supply system control method according to claim 9, wherein said information supplying step provides broadcast data virtually continuously supplied to said service subscriber terminal as said information.

15. The information supply system control method according to claim 9, wherein said information supply step presents said information in response to information request from said service subscriber terminal existing in said service area.

16. The information supply system control method according to claim 9, wherein said central server means has a step of distributing relevant reception information to the necessary local server means based on said transmission destination specification condition of the information received from each of said local server means.
