Abstract

The present invention relates to the field of the Internet of Things, in particular to a method, device and system for scheduling communication resources in the field of the Internet of Things, so as to meet the low-latency communication requirements in Internet of Things applications. When the Internet of Things application server determines that it is necessary to activate cooperative radio resource scheduling for a certain terminal according to business requirements and business scenarios, the Internet of Things application server sends a cooperative radio resource scheduling activation request to the wireless transceiver node, requesting that the wireless transceiver node The server requires the terminal to perform cooperative wireless resource scheduling; after receiving the request, the wireless transceiver node allocates wireless resources for the terminal with higher priority or higher efficiency. If there is no need for the terminal to apply for wireless resources, the wireless transceiver node actively sends The terminal allocates wireless resources to reduce the wireless communication delay of the terminal and realize the low-latency communication requirement in a specific business scenario.

Description

technical field [0001] The present invention relates to the field of the Internet of Things, in particular to a method, device and system for scheduling communication resources in the field of the Internet of Things. Background technique [0002] With the development of Internet of Things (Internet of Things) technology, Internet of Things technology has begun to be applied and promoted in various industries, such as smart home, intelligent transportation, industrial control, telemedicine, etc. In some industry-specific IoT applications, due to the characteristics of the application scenarios and application requirements, they are extremely sensitive to communication delays. For example, in vehicle to everything (V2X), that is, the Internet of Things in which vehicles communicate with everything, vehicles can perceive information about vehicles or pedestrians outside the driver's current field of vision through V2X technology, thereby avoiding potential collisions; vehicles ...
