Problems solved by technology

[0003] However, the current wireless communication technology cannot meet the low-latency communication requirements of IoT applications, such as the V2X wireless communication technology based on cellular technology developed by 3GPP, user equipment (UE) or vehicle and packet data gateway (packet The delay between data network gateways (P-GW) is set to 50ms, which cannot meet the wireless resource scheduling delay requirements of vehicles in V2X communication in emergency situations

Abstract

The invention relates to the field of the Internet of Things, in particular to a method of communication resource dispatching, device and system in the field of the Internet of Things so as to meet the low-latency communication requirements in the application of the Internet of Things. When an Internet of Things application server determines the need to start cooperative wireless resource dispatching for a terminal according to business requirements and a business scene, the Internet of Things application server sends a cooperative wireless resource dispatching activation request to a wirelesstransceiver node and requests the wireless transceiver node to perform cooperative wireless resource dispatching on the terminal according to the requirements of the Internet of Things application server; and after the wireless transceiver node receives the request, the wireless resources are allocated to the terminal with higher priority or higher efficiency, if the terminal does not need to apply for the wireless resources, the wireless transceiver node actively allocates the wireless resources to the terminal, and thus, the wireless communication delay of the terminal is reduced, and the low-latency communication requirements in a specific business scene is realized.

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 IoT applications in some specific industries, 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; vehi...
