Method for transmitting data between a vehicle and a vehicle security system, a transmission and reception device, and data transmission system

A transmission and reception device for use in a vehicle, comprising:

• a plurality of transmission units for transmitting data over different transmission channels between the vehicle and a traffic security system;
• at least one data processing system for creating data packets for transmission to the traffic security system, and for processing the data packets transmitted to the vehicle;
• an onboard multilink unit coupled to the transmission channels and connected to said at least one data processing system, said onboard multilink unit being configured to route the data packets to be transmitted to the transmission channels, and/or to obtain received said data packets from the transmission channels;
• a multilink management unit having a memory and being connected to said onboard multilink unit and being coupled to the transmission channels;
• a specified set of rules stored in said memory of said multilink management unit, and containing a plurality of different transmission configurations for routing the data packets to be transmitted;
• and
• said multilink management unit being configured:
• to measure a transmission quality which is available for a data transmission in the transmission channels;
• to select a transmission configuration from a type of the data to be transmitted and ascertained transmission qualities, and additional specifications according to the specified of rules;
• to notify the traffic security system by transmitting an identifier to the traffic security system:
• as a separate data packet from the vehicle to the traffic security system;
• or
• as a piggy-back component of the data packets specified in the vehicle for the transmission;
• and
• to specify the transmission channels and to add the identifier to the data packets characterizing the transmission configuration, corresponding to a respectively selected transmission configuration for individual said data packets associated with a service;
• and
• to actuate said onboard multilink unit for transmitting the identifier and the data packets to the traffic security system over the transmission channels specified corresponding to the transmission configuration.
