Solution Overview

Problem

In machine-to-machine (M2M) communication networks, the existing resource notification methods lead to slow query speeds and low efficiency when querying resource attributes on remote Common Service Entities (CSEs), as they require linking to the original resource address, increasing signaling and network resource usage.

Innovation Solution

The method creates corresponding attributes on notification resources, allowing direct querying on remote CSEs without needing the original resource link, thereby reducing signaling and improving query speed and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If resource attributes are queried on remote CSEs by linking to original resource address, then the query can be completed, but the query speed is slow and efficiency is low

Engineering Contradiction:
Improvequery efficiencyVSAvoidquery time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-creating notification resources with complete attribute information on remote CSEs before queries are made. When a resource is created or updated at the original CSE, the same resource attributes are proactively pushed to remote CSEs in advance. This allows queries to be resolved locally at the remote CSE without needing to link back to the original resource address, significantly improving query speed and efficiency.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If resource attributes are queried by linking to original resource address, then the query can be completed, but signaling and network resource usage increase

Engineering Contradiction:
Improvequery completenessVSAvoidnetwork resource usage
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies copying by creating duplicate notification resources with identical attribute information on remote CSEs. Instead of querying the original resource through network links, the remote CSEs store local copies of resource attributes that can be queried independently. This eliminates the need for continuous network signaling and reduces network resource usage while maintaining query completeness.

Inventive Principle:
Principle #26Copying

AI summary

The embodiment of present invention discloses a method for implementing resource attribute notification and a common service entity. The method includes that: the common service (CSE) entity receives a resource update request, the resource update request containing an original resource address parameter and a parameter of an attribute able to be notified; and the CSE finds a corresponding original resource and an attribute thereof created locally according to the original resource address parameter; if it is judged that the parameter of an attribute able to be notified contains an attribute name of an attribute able to be notified, and the original resource has been notified to a remote CSE, but the original resource has not created "an attribute that has been notified", the CSE sends the resource update request to the remote CSE and carries a notification resource address of the original resource on the remote CSE, the attribute name of the attribute able to be notified, and the attribute value stored locally.
