Abstract: A system has a plurality of agents with each of a plurality of road side units (RSUs) having at least an agent of the plurality of agents being deployed to deploy and manage interactive regional broadcast services. Each agent includes a RSU receiving/transmitting device to receive at least a service deployment message and broadcast at least a service tracking request, and a storage device to maintain a service table recording at least a service that currently performs broadcasting service content on a corresponding RSU and a service-related topology table recording at least a RSU in a neighborhood of the corresponding RSU when an interactive regional service broadcasting being performed. A processor in the agent may perform interactive regional service deployment, interactive regional service termination and interactive regional service tracking, manage and accomplish at least a broadcast service through the corresponding RSU and the two tables.
