CSE Trigger Management for M2M Device Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machine-to-Machine (M2M) communication networks lack a solution for triggering connections between devices and service layer servers, which is essential for effective communication.
Innovation Solution
A method and device for trigger management in a Common Service Entity (CSE) that involves sending a trigger request to a network element of a bearer network, including information such as a trigger message, external identifier, and resource identifier, and updating attributes based on the response received from the network element to manage the trigger resource and policy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If M2M communication networks use existing trigger solutions from WO 2013/061614 A2 and 3GPP TS 23.682 v12.0.0, then some basic triggering capability is provided, but the problem of effectively triggering connections between devices and service layer servers remains unsolved
Solution Approach 1:
The patent introduces a Common Service Entity (CSE) as an intermediary between M2M applications and the bearer network. The CSE manages trigger resources and policies, sending trigger requests to network elements (like MTC-IWF) and coordinating the triggering process. This intermediary approach resolves the contradiction by centralizing trigger management functionality, making the system more reliable while abstracting the complexity from individual devices and applications.
Solution Approach 2:
The patent segments the trigger management system into distinct functional components: trigger resources (individual trigger configurations), trigger policies (rules governing trigger behavior), and the CSE (management entity). This segmentation allows each component to be managed independently, improving reliability through modular fault isolation while organizing complexity into manageable segments rather than a monolithic system.
2Adaptability or versatility
If a CSE manages trigger resources and policies with multiple attributes (validity time, priority indicator, backoff time), then trigger management capability is improved, but the complexity of managing these resources increases
Solution Approach 1:
The CSE is designed as a universal trigger management entity that handles multiple types of trigger resources and policies with various attributes (validity time, priority indicator, backoff time). Rather than creating separate management mechanisms for each attribute, the CSE provides a unified multi-functional platform that manages all trigger-related parameters through standardized interfaces and procedures, thereby improving adaptability while containing complexity within a single versatile component.
Solution Approach 2:
The patent manages trigger resource complexity by treating attributes like validity time, priority indicator, and backoff time as configurable parameters that can be dynamically adjusted. The CSE modifies these parameters based on policy rules and network conditions, allowing flexible trigger management without hardcoding complex logic. This parameter-based approach enables adaptability while keeping the management mechanism relatively simple and systematic.

AI summary
The disclosure provides a method and device for trigger management of a CSE, the CSE and a network element of a bearer network. The method includes that: the CSE sends a trigger request to a network element of a bearer network, wherein the trigger request carries the following information: a trigger message, an external identifier of the CSE, an identifier of a triggered device and a resource identifier of a trigger resource corresponding to the trigger request; the CSE receives a trigger response, which corresponds to the trigger request, sent by the network element of the bearer network; and the CSE updates a first attribute of the trigger resource according to the trigger response. By means of the technical solution provided in the disclosure, the technical problem in the related art that M2M communication does not provide a solution of correspondingly triggering connection between a device and a service layer server yet is solved, thereby achieving the device trigger management of a service layer.
