Abstract

The invention relates to an optimization method of Internet of Vehicles acceleration information transmission. When a vehicle generates burst emergency security early warning information, the vehicleuploads original conventional information on a pre-configured SPS resource, the conventional information carries a new resource request and an illustration that notifies a network user side to generate new information by means of the original conventional information, or the vehicle transmits burst information on the pre-configured SPS resource, and the burst information carries the new resource request and an illustration indicating that an original information packet is temporarily occupied to transmit resources. By adoption of the optimization method provided by the invention, the transmission waiting delay of the burst information can be shortened, thus shortening the transmission delay of the burst information.

Description

technical field [0001] The invention relates to the field of vehicle network technology, in particular to an optimization method for accelerating information transmission of the vehicle network. Background technique [0002] In-vehicle network communication can improve vehicle driving comfort and reduce traffic accidents, which has become an inevitable trend in the development of modern automotive electronics technology. Vehicle networking (V2X, vehicle to everything) includes V2V (vehicle-vehicle communication), V2I (vehicle-road communication) and V2P (vehicle-pedestrian communication), which can realize intelligent traffic management, intelligent dynamic information service and intelligent control of vehicles The integrated network is a typical application of Internet of Things technology in the field of transportation systems. At present, there are mainly two standards in the field of V2X communication technology, DSRC and LTE-V2X. The former specifies the communicatio...
