Method for annunciating original resource and corresponding node

Abstract

The invention provides a method for annunciating an original resource and a corresponding node. A local CSE sends an annunciation resource creation request to a remote CSE that is not annunciated according to an annunciation request of an application entity AE to the original resource and starts a timer; if receiving success response indicating annunciation resource creation success, the local CSE adds the address of the annunciation resource contained in the success response in an "annunciation to" attribute of the original resource; before the timer is due, if the local CSE receives the response of the remote CSE and the response comprises the success response, the local CSE stops the timer and returns response carrying a current value of the "annunciation to" attribute to the AE; and when the timer is due, if the local CSE receives the success response returned by a part of remote CSE, the local CSE returns the response carrying the current value of the "annunciation to" attribute to the AE. The local CSE can annunciate the original resource on the AE to the remote CSE and return an annunciation result to the AE in time to avoid resource waste.

Description

technical field [0001] The present invention relates to the field of Machine Type Communication (MTC: Machine Type Communication), and more specifically, relates to a method for managing raw resources and corresponding nodes. Background technique [0002] figure 1 It is a diagram of an M2M system architecture. As shown in the figure, an M2M communication network is composed of various M2M nodes and a bearer network. The M2M nodes communicate with each other through the bearer network, and an M2M node includes at least one Application Entity (AE) or one Common Service Entity (CSE). AE is a logical unit for executing actual M2M applications, and CSE is a logical unit for managing and serving applications. [0003] The M2M nodes in the M2M system architecture include application nodes, intermediate nodes and basic nodes. Among them, the application nodes are the end execution nodes, such as smart meters, temperature measurement and control sensors, fire alarms, smart home app...

Problems solved by technology

[0006] In practical applications, the AE-related resources on the application node need to be registered with the CSE on the application node instead of the CSE of the intermediate node and the CSE of the basic node. In the existing technology, for example, the application on the basic node needs to find When applying an application on a node, it is necessary to send a request to all intermediate nodes connected to the basic node, and the intermediate node forwards the query request to each application node, which not only consumes a lot of network resources, but also takes a long time
