Wireless communication method for prioritizing data packets in vehicles
A recently filed patent (Publication Number: US20230199544A1) describes a method for wireless communication between a router in a moving vehicle and a stationary communication server outside the vehicle. The method involves using at least one external mobile network and at least one link for communication. The method includes providing two output buffers, receiving data packets of a data stream, determining the data type of the stream, and selecting the appropriate output buffer based on the data type. The data packets are then transferred to the selected output buffer for subsequent transmission on the link.
The patent also describes additional features of the method. One of the output buffers can function as a queue, following a first in, first out (FIFO) principle for transmitting data packets. The prioritized data types are assigned a priority value, and the first output buffer operates as a priority queue, serving data packets with higher priority before those with lower priority. If multiple links are available, data packets from the two output buffers can be transmitted on different links.
The determination of the data type belonging to the set of prioritized data types can be based on factors such as destination, size, and pattern of the data stream. Video data streams are not included in the set of prioritized data types, but other types such as voice-over-IP (VOIP), transaction, authentication, and VPN data streams are included.
The method ensures that data packets from both output buffers are transmitted at the same output rate. The bandwidth for data streams sent through the second buffer can be restricted to a maximum value. The stationary communication server can be an aggregation server, aggregating data packets from different links, and the output buffers can transmit data packets on multiple simultaneously usable links.
The patent also describes the application of the method in a wireless communication system for a moving vehicle, such as a train. The system includes at least one router in the vehicle, capable of wireless data communication with a stationary communication server through external mobile networks. The system includes the same features as described in the method claims.
In summary, the patent describes a method and system for wireless communication between a router in a moving vehicle and a stationary communication server. The method involves prioritizing data types, selecting appropriate output buffers, and transferring data packets for subsequent transmission. The system implements this method and can be used in moving vehicles like trains.
