摘要

The on-board wireless communication router (260) transmits the request according to the following routing rules: - in the case of availability of the only permanent low-speed wireless link (PL), the on-board communication router (260) transmits the request to the embedded cache server (280) in the vehicle (20) to serve the response to the request if it is available, and in case of unavailability of the response, the on-board router (260) is able to fetch the answer to the request directly over the Internet (800) via the permanent low-speed wireless link (PL) and the central communication router (360) on the ground, - in case of availability of the additional high-speed (HDL) point-to-point wireless link embedded communication router (260) transmits the request to the central cache server (380) implanted on the ground via the additional one-time high speed (HDL) wireless link to serve the response to the request if it is said available in the central cache server (380) on the ground, and in case of unavailability of the response, the onboard communication router (260) is able to fetch the response to the request directly on the Internet (800) via the link additional high-speed point-to-point wireless (HDL) and the central communication router (360) on the ground.
