Abstract

The embodiment of the present invention discloses a file caching method, device and system. The file caching method includes: when the first vehicle enters the transfer sub-area of ​​the cache area from the storage sub-area of ​​the cache area, the stored data packet is transmitted to A second vehicle entering the handover sub-area from outside the buffer area. In the embodiment of the present invention, when the first vehicle is about to leave the cache area (that is, enters the handover sub-area from the storage sub-area), it transmits the data packet stored by itself to the second vehicle that is about to enter the cache area (that is, enters from outside the cache area) Handover sub-area), so that it can resist the high-speed mobility of vehicles and store data packets in the cache area for a long time.

Description

technical field [0001] The embodiments of the present invention relate to the field of wireless communication, and in particular to a file caching method, device and system. Background technique [0002] At present, with the emergence of a large number of in-vehicle applications, the demand for wireless communication in high-speed vehicles has increased rapidly, which has brought a huge burden to the core network and infrastructure, which in turn has led to a decline in user experience quality. In related literature, the concept of Information-Centric Network (ICN, Information-Centric Network) is proposed. In this case, network edge caching is a key technology to bring data closer to users. By storing data at the edge of the network, repeated requests for cached data can be greatly reduced in the core network, thereby greatly reducing the load on the core network and infrastructure. , to improve user experience. However, due to the high-speed mobility of vehicles, a vehicl...
