Abstract

A mobile type service provider terminal registers a service providing area to a presence management server before a service starts. The presence management server creates a status management table of the mobile type service provider terminal. When the presence of the mobile type service provider terminal is detected in an area, the terminal registers information contents, which are delivered to subscribers, to an information delivery server. When the information delivery server stores the registered information contents to an information contents database and completes the creation of an information providing table, it notifies a service control server of the information. The service control server creates a message with reference to the information notified from the information delivery server and delivers it to the subscribers.

Claims

1. An information delivery system comprising:

a mobile type service provider terminal which moves in a service providing area and provides a service to a subscriber terminal in the vicinity of the service providing area;

a presence management server that manages presence information of the service provider terminal;

an information delivery server that previously registers and manages information which is desired to be delivered from the service provider terminal to the subscriber terminal; and

a service control server that notifies the subscriber terminal participating to the service of the service provider of the delivery of the information registered to the information delivery server when a status of presence of the service provider changes,

wherein the information managed by the information delivery server can be updated while the service provider terminal moves in the service providing area.

2. The information delivery system according to claim 1, wherein the presence management server manages whether or not the service provider terminal exists in a particular area as presence information.

3. The information delivery system according to claim 1, wherein a message is defined between the service control server and the subscriber terminal making use of the MESSAGE function of SIP (Session Initiation Protocol).

4. The information delivery system according to claim 3, wherein the service control server pushes application control information to the subscriber terminal making use of the message defined between the subscriber terminal and the service control server and controls the application provided to the subscriber terminal.

5. The information delivery system according to claim 3, wherein the service control server delivers the message defined between the subscriber terminal and the service control server to the subscriber terminal.

6. The information delivery system according to claim 1, wherein the information delivery server comprises table means for managing the information of the service providing area, the information of the service provider, contents list information, and contents type information.

7. The information delivery system according to claim 1, wherein the service control server comprises table means for managing the information of the service providing area, the information of the service provider and the information of a service utilizing user.

8. An information delivery method used to an information delivery system, wherein:

a mobile type service provider terminal moves in a service providing area and provides a service to a subscriber terminal in the vicinity of the service providing area;

a presence management server manages presence information of the service provider terminal;

an information delivery server previously registers and manages information in which the information delivery server desires to deliver from the service provider terminal to the subscriber terminal;

a service control server notifies the subscriber terminal participating to the service of the service provider of the delivery of the information registered to the information delivery server when a status of presence of the service provider changes; and

the information managed by the information delivery server can be updated while the service provider terminal moves in the service providing area.

9. The information delivery method according to claim 8, wherein the presence management server manages whether or not the service provider terminal exists in a particular area as presence information.

10. The information delivery method according to claim 8, wherein a message is defined between the service control server and the subscriber terminal making use of the MESSAGE function of SIP (Session Initiation Protocol).

11. The information delivery method according to claim 10, wherein the service control server pushes application control information to the subscriber terminal making use of the message defined between the subscriber terminal and the service control server and controls the application provided to the subscriber terminal.

12. The information delivery method according to claim 11, wherein the definition of the message includes the identification information of the service provider, a command for controlling the application, and a message type and a message body showing the contents of the command.

13. The information delivery method according to claim 12, wherein a first command for automatically starting the application and a second command for updating an application being displayed are included as the command.

14. The information delivery method according to claim 12, wherein a type of the message type includes WEB URL (Uniform Resource Locator) for accessing a WEB server, Vo DURL for accessing a video delivery VoD (Video on Demand) by the unicast, multicast group address for accessing a video delivery by the multicast and the broadcast, and text information showing that a phone number and a message are used to make a phone call.

15. The information delivery method according to claim 10, wherein the service control server delivers the message defined between the subscriber terminal and the service control server to the subscriber terminal.

16. The information delivery method according to claim 8, wherein the information delivery server comprises table means for managing the information of the service providing area, the information of the service provider, contents list information, and contents type information.

17. The information delivery method according to claim 8, wherein the service control server comprises table means for managing the information of the service providing area, the information of the service provider, and the information of a service utilizing user.
