摘要:
PURPOSE: A delivery method of wireless network packets based on vehicles and a device thereof are provided to relieve deterioration in network function due to explosive traffic inflow caused by the increasing number of terminal devices and diversification of them using network. CONSTITUTION: A communications unit (610) is connected to the intranet different from the network. The communications unit communicates with the first intranet terminal and the second intranet terminal. The first intranet terminal is installed in a vehicle periodically passing assigned specific route. The second intranet terminal is installed on a spot where the vehicle stops. A packet management module (620) analyzes the network state where the transferred packets are delivered. The packet management module controls the communications unit for the transferred packets to be delivered to the first intranet terminal and the second intranet terminal when the network is not clear.
