Method, system and device for realizing low-delay resource scheduling and train

Abstract

The embodiment of the invention discloses a method, system and device for realizing low-delay resource scheduling, and a train. The method comprises the steps: determining an authorization time slot of a local node for transmitting first service data according to a first resource scheduling request message sent by a previous hop node and a common node time slot table of the local node; and the authorization time slot can be determined by sending the resource scheduling request message once between the two hops of nodes, and the interaction process between the nodes required for determining the authorization time slot is reduced, so that the time consumed by communication between the trains serving as the nodes is reduced, and the time delay of communication between the trains is reduced.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method, system, equipment and train for realizing low-latency resource scheduling. Background technique [0002] During the operation of the train, it needs to communicate with other trains and the control center through the ground equipment to realize the operation control of the train and ensure the normal operation of the train. [0003] Currently, communication between trains mainly relies on ground equipment. Ground equipment forwards train-generated messages to other trains. When building a communication system, the construction of a large number of ground equipment will lead to a higher construction cost of the train communication network. However, if the communication between trains is adopted, although the cost of building ground equipment can be reduced, the communication process is easily affected by the operation of the train, and the communic...

When building a communication system, the construction of a large number of ground equipment will lead to a higher construction cost of the train communication network

However, if the communication method between trains is adopted, although the cost of building ground equipment can be reduced, the communication process is easily affected by the operation of the train, and the communication delay is relatively high.
