Abstract

The invention discloses a resource discovery method and an apparatus thereof and relates to the communication network technology field. The method and the apparatus are used to solve a problem that network cost is large. In embodiments of the invention, the method comprises the following steps of through a server, receiving a first resource discovery request message sent by a client; according to the first resource discovery request message, searching a resource; when a created group is indicated to be a created static state group, creating the static state group and taking the searched resource as a member of the static state group; when the created group is indicated to be a created dynamic group, creating the dynamic group; setting a filtering condition in the first resource discovery request message to be the filtering condition used for determining the dynamic group and taking the searched resource satisfying the filtering condition as a dynamic group member; and finally sending a first response message carrying a URI of the created group to a client. The scheme provided in the invention is suitable for a resource discovery process.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a method and device for resource discovery. Background technique [0002] With the rapid development of the Internet of Things technology, M2M (Machine-to-Machine Communications, machine communication) has been widely used in more and more industries and fields. In order to meet the needs of different industry application services, a unified M2M The platform implements some public capabilities, such as resource discovery. [0003] Specifically, the M2M platform can be the oneM2M platform. The current resource discovery method in the oneM2M architecture is that when the CSE (Common service Entity, public business entity) in the oneM2M system receives a resource discovery request message, it determines the resource discovery according to the destination address of the request message. range, and then search for resources that meet the filter conditions, and ...
