Internet of Things device trigger method, device and system

Abstract

An object of the invention is providing a method, device and system for Device Trigger in IoT. The network device obtains device trigger request(s) corresponding to one or more target devices, and determines, based on the device trigger request in conjunction with subscribed data corresponding to the target device, a device trigger response corresponding to the device trigger request. Compared with the prior art, the present invention provides a proxy mechanism used in IoT / MTC, i.e., with the network device as a proxy for the target device, a device trigger request corresponding to the target device is processed to reduce unnecessary trigger request to the target device, and reduce resource / energy (such as CPU, memory, network connection, etc. . . . ) consumption for the IoT / MTC devices and network; furthermore, the present invention would further reduce the response time of device trigger and improve the quality of services in IoT.

Description

technical field [0001] The present invention relates to the field of the Internet of Things, in particular to a technology for triggering an Internet of Things device. Background technique [0002] In today's computer and communication systems, the scale and complexity of IoT will grow exponentially. The Internet of Things (IoT), also known as Machine-Type Communications (MTC) or Machine-to-Machine Communications (M2M), as an emerging paradigm, is full of challenges and opportunities. Among them, in the Internet of Things, intelligent computer devices collect data, devices transmit information to each other, cooperate to process information and perform operations automatically. [0003] Since most of the smart computing devices deployed in IoT will be resource-constrained devices, a core challenge in IoT is to save energy or conserve resources. How to save energy on resource-constrained smart devices (such as various sensors, etc.) and networks (such as low-power wireless ...

AI Technical Summary

Problems solved by technology

However, a large number of device trigger requests (devicetriggerrequests) from different clients or application servers (Application Server, AS) may cause a heavy load to the MTC device, thereby causing a large amount of resource or energy consumption to the device; Can place a heavy load on the network

The above situation may be exacerbated by poor service conditions, for example, delays in triggering responses from devices, network congestion, etc.
