Problems solved by technology

However, this resource allocation method makes it impossible for the base station to obtain the actual communication situation between the underlying vehicles. Once the actual communication situation is poor, when the vehicle broadcasts through its allocated transmission resources, problems such as interference and low transmission success rate may occur , and if there are few vehicles in some areas, then the resource reuse rate in this area is not high, so the current resource scheduling method makes the transmission resource scheduling unreasonable

Embodiment Construction

[0210] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0211] The safety messages sent by vehicles can be divided into two categories. One is event-triggered messages. We call this type of message DENM (Decentralized Environmental Notification Message, DENM), such as warnings for stationary vehicles ahead, warnings for slow vehicles ahead, and emergency braking. warning, overtaking warning, etc. When these events occur, the event vehicle will generate a corresponding message broadcast to inform the surrounding vehicles, reminding them to make corresponding avoidance to avoid possible dangers. Another type of message is a periodic status notification message. We call this type of message a CAM message (Cooperative Awareness Message). This type of message requires the vehicle to broadcast it...

Abstract

Disclosed are a resource scheduling method, a message sending method, and devices, which fall within the technical field of communications. The method comprises: acquiring pavement state data generated by a plurality of user equipment (UE) in a running process; and performing resource scheduling on the plurality of UEs according to the pavement state data. The pavement state data generated by a vehicle-mounted UE on a pavement in the running process is acquired in real time by means of a base station, and an actual pavement situation potentially influencing communication is obtained so as to determine whether the current resource scheduling is rational, such that resource scheduling is performed on the UE on the basis of the actual situation, and the reuse rate of resources and the success rate of the communication between vehicles in an internet of vehicles can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a resource scheduling method, a message sending method and equipment. Background technique [0002] The Internet of Vehicles (IoV) is a new management service network based on the combination of the Internet and the Internet of Things technology and incorporating a large number of software technologies and information service content. In the Internet of Vehicles, vehicles are used as nodes and information sources, and advanced sensing technology, network technology and wireless communication technology are used to process and share a large amount of information through vehicles or mobile phones, so as to realize "people-vehicle-road-environment-society" The interconnection and intercommunication can achieve intelligent identification, positioning, tracking, supervision and push services, so as to realize smarter, safer, more environmentally friendly and more com...
