Abstract

A system includes a plurality of subsystems respectively assigned to a plurality of regions in a geographic space, the plurality of subsystems including a first subsystem assigned to a first region of the plurality of regions. The first subsystem includes a first event server operable to generate a first dynamic event agent for handling a dynamic event occurring in the first region, the first dynamic event agent operable to issue a request to a second subsystem, of the plurality of subsystems, assigned to a second region next to the first region, the request causing a second event server of the second subsystem to generate a second dynamic event agent for handling the dynamic event in the second region. The first subsystem further includes a first mobile object server operable to transmit a signal based on information about the dynamic event to a mobile object in the first region.

based on the receipt of the request by the second subsystem, a second event server of the second subsystem generating a second dynamic event agent for handling the dynamic event in the second region;

a first mobile object server operable to transmit a signal based on information about the dynamic event to a mobile object in the first region; and

2. The system of claim 1, wherein the first dynamic event agent issues the request to the second subsystem if a calculated probability that the second region will be affected by the dynamic event exceeds a threshold value.

3. The system of claim 1, wherein the second event server generates the second dynamic event agent upon the receipt of the request by the second subsystem if a dynamic event agent for handling the dynamic event has not yet been generated by the second subsystem.

4. The system of claim 1, wherein the second event server is operable to register the second dynamic event agent with the first dynamic event agent.

5. The system of claim 1, wherein the second dynamic event agent is operable to issue a subsequent request to a third subsystem, of the plurality of subsystems, assigned to a third region next to the second region, the request causing a third event server of the third subsystem to generate a third dynamic event agent for handling the dynamic event in the third region.

6. The system of claim 5, wherein the second dynamic event agent issues the subsequent request to the third subsystem if a calculated probability that the third region will be affected by the dynamic event exceeds a threshold value.

7. The system of claim 5, wherein

the third subsystem is operable to receive the request,

the third event server is operable to generate the third dynamic event agent upon the receipt of the request by the third subsystem,

the third event server is operable to register the third dynamic event agent with the first dynamic event agent, and

the third subsystem includes a third mobile object server operable to transmit a signal based on information about the dynamic event to a mobile object in the third region.

8. The system of claim 1, wherein

the first dynamic event server maintains a registry of all dynamic event agents that have been generated for handling the dynamic event,

the first dynamic event server is operable to issue, to all subsystems of the plurality of subsystems having a dynamic event agent in the registry, a notification that the dynamic event is no longer occurring in the first region, and

the second dynamic event server is operable to eliminate the second dynamic event agent after receipt of the notification by the second subsystem.

9. The system of claim 8, wherein the second dynamic event server eliminates the second dynamic event agent when the dynamic event is no longer occurring in the second region after receipt of the notification by the second subsystem.

10. The system of claim 9, wherein

the second subsystem notifies the first subsystem when the second dynamic event agent is eliminated, and

the first dynamic event server eliminates the first dynamic event agent when the dynamic event is no longer occurring in the first region and all dynamic event agents that were generated for handling the dynamic event have been eliminated.

11. The system of claim 1, wherein

the second event server includes a second event agent for handling events that occur in the second region, and

the second dynamic event agent is operable to receive information relating to an event from a mobile object in the second region, update a status of the second dynamic event based on the information if the received information relates to the second dynamic event, and forward the received information to the second event agent if the received information relates to an event other than the second dynamic event.

12. The system of claim 1, wherein the first event server is operable to generate the first dynamic event agent before occurrence of the dynamic event based on statistical information about occurrence of events in the first region.
