The generated events are stored in the event store in chronological order (704), and as the simulation time passes, the events stored in the event store are sequentially taken out (705) to identify the characteristics of the event and the corresponding units according to the identified characteristics. Send events to the simulation system (706, 712).

When the characteristic of the event is collection or reception, the generated event is transmitted together with the event information to the dispatching unit China simulation system (706).
