Problems solved by technology

[0005] However, in the above-mentioned existing standards, radio resources suitable for such network conditions cannot be effectively utilized: in congested urban areas with dense VANETs, ​​a large number of safety messages and control messages need to be transmitted within the CCH interval
The fixed length of CCH may not provide enough bandwidth in these scenarios, leading to potential collisions and QoS degradation
On the other hand, if the node density is sparse, the CCH interval will be idle for a long time

Abstract

The present invention provides a method for communication, an RRM server, a RSU, and a node. The method includes: performing, by a Radio Resource Management RRM server, segmentation of an area in a communication network to form at least one segment for at least one Roadside Unit RSU respectively; allocating, by the RRM server, channels for the at least one segment; sending, by the RRM server, network segmentation information and channel allocation information to each of the at least one RSU, wherein the network segmentation information indicates a segment for the RSU and the channel allocation information indicates channels allocated for the segment so that RSU communicates with a node which enters the segment through the channels allocated for the segment.

Description

technical field [0001] The present invention generally relates to the technical field of communication, and more specifically, relates to a communication method, a server, a roadside unit and a node. Background technique [0002] Vehicular Ad hoc Networks (VANET) enable communication between nearby vehicles and between vehicles and nearby fixed infrastructure. This leads to the design of multiple applications to improve the safety of future transportation systems and to provide many industrial services and entertainment services. Dedicated Short Range Communication (DSRC, Dedicated Short Range Communication), as the main communication technology, enables vehicle-to-vehicle (V2V, vehicle-to-vehicle) and vehicle-to-infrastructure (V2I, vehicle-to-infrastructure) communication to realize such applications. Due to the large number of vehicles and the complex road architecture, in terms of large networks and a large number of nodes, it is expected to form large dense vehicle net...
