Abstract

The present invention provides a channel control method for the Internet of Vehicles, including: dividing the communication channel in the Internet of Vehicles into at least one service channel and at least one control channel; multiple service channels perform data transmission within the same time range, and Within the same time range, the status of the safety message is monitored through the control channel, and a service channel is allocated to the safety message. The channel control method of the Internet of Vehicles provided by the present invention realizes the synchronous operation of the control channel and the service channel through the channel control method. While the service channel is working, the control channel monitors the state of the safety message in real time. When no safety message arrives, the control channel will not Affect the continuous work of the service channel, improve the utilization rate of the service channel transmission message, and at the same time, through the message classification, the security message with high importance can be transmitted in time.

Description

technical field [0001] The present invention relates to the fields of communication and vehicle technology. Specifically, the present invention relates to a channel control method for the Internet of Vehicles, a cooperative communication method, and a corresponding terminal and system. Background technique [0002] VANET (Vehicle Ad hoc Network) is a wireless ad hoc local area network based on the 802.11p / WAVE protocol stack. The WAVE protocol divides the frequency band into 7 channels, which are numbered 172, 174,..., 184 in sequence. Among them, channel 178 is a control channel (CCH), and others are service channels (SCH). The control channel is mainly used to control the service channel, not for data transmission, and the service channel is completely used for data transmission. [0003] When the VANET protocol stack uses the frequency band channel, 100ms is a cycle, and each cycle is divided into two parts: control process and data process, each occupying 50ms. There ...
