Internet of Things resource subscription method, device, and system

Abstract

The present application relates to the field of communication, relating in particular to an Internet of Things resource subscription method, device, and system, used for meeting the service requirements for flexible subscription of multiple resources, object instances, or objects in Internet of Things service scenarios. By means of adding parameters to a subscription request message, the resourcesubscription method enables a device in a multi-resource subscription scenario to identify which parameters need to be reported and which parameters are only used as subscription determination conditions, reducing the amount of data to be reported on the device side and the bandwidth that needs to be occupied for data transmission, decreasing the performance consumption on the device and server sides. The resource subscription method also enables the server to use logical expressions to flexibly set subscription conditions in a subscription request, greatly increasing the flexibility of resource subscription in a multi-resource subscription scenario.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method, device and system for resource subscription in the Internet of Things field. Background technique [0002] With the rich services and applications provided by the Internet of Things, such as Internet of Vehicles, smart home, smart medical care, remote meter reading, etc., a large number of Internet of Things devices, such as sensors, smart devices or terminals, will generate massive amounts of data. The performance impact of data on the transmission network and various devices, especially those with limited capabilities, in the design and deployment of the Internet of Things system, it is hoped to reduce the interaction of data or messages as much as possible, so as to save the occupation of transmission resources, energy consumption of devices, and prolong battery life etc. [0003] The resource subscription mechanism can enable the terminal or device to active...

Problems solved by technology

For example, the Lightweight Internet of Things communication (LightweightM2M, LwM2M) protocol uses write-attributes and observe operations to subscribe resources, but the write-attributes operation can only set subscription rules for a single resource, object instance or object, and the observe operation can only subscribe to a single A resource, a single object instance, or a single object
