Solution Overview

Problem

Current Machine Type Communication (MTC) networks lack sufficient mechanisms to transfer management information between the Public Land Mobile Network (PLMN) and the M2M service layer, limiting collaborative and cooperative operations.

Innovation Solution

Incorporating a trigger controller and a notification service controller in the MTC-IWF and SCS entities to facilitate the exchange of management information through a subscription request and notification service, enabling the transfer of collected data between the PLMN and the M2M service layer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the current MTC network architecture is used without additional information transfer mechanisms, then the network structure remains simple, but the collaborative operations between PLMN and M2M service layer are insufficient

Engineering Contradiction:

Improvecollaborative operations capabilityVSAvoidnetwork architecture complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The notification service controller is designed to handle multiple functions: it manages subscription requests from both PLMN and M2M service layer, coordinates information transfer between these layers, and handles device trigger notifications. This multi-functional design enables collaborative operations without requiring separate dedicated systems for each function, thus improving adaptability while controlling complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The notification service controller acts as an intermediary between the PLMN and the M2M service layer. It receives subscription requests from either side, manages the information exchange, and coordinates the transfer of management information. This intermediary role enables collaborative operations by bridging the two layers without requiring direct complex interactions between them, thus improving versatility while maintaining architectural simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If management information transfer mechanisms are added to enable collaborative operations, then the collaborative operations capability is improved, but the network architecture complexity increases

Engineering Contradiction:

Improveinformation transfer capabilityVSAvoidsignaling mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The notification service controller implements a universal information transfer mechanism that handles multiple types of management information exchange between PLMN and M2M service layer through a single coordinated interface. This multi-functional signaling mechanism improves information transfer capability while avoiding the need for multiple separate signaling systems, thus controlling the increase in architecture complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a notification service controller is introduced to transfer management information, then the collaborative operations are enhanced, but the entity complexity increases

Engineering Contradiction:

Improvemanagement information transferVSAvoidMTC-IWF entity complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The notification service controller within the MTC-IWF entity is designed to perform multiple functions: receiving subscription requests from both PLMN and M2M service layer, managing device trigger notifications, and coordinating information transfer between the two layers. This multi-functional design enhances management information transfer capability while consolidating multiple responsibilities into a single controller, thus limiting the increase in entity complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The notification service controller serves as an intermediary component within the MTC-IWF entity that manages the complex information transfer tasks between PLMN and M2M service layer. By centralizing the coordination function in this intermediary controller, the system achieves enhanced collaborative operations while containing the increase in overall entity complexity through functional consolidation.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A Machine Type Communication Inter Working Function (MTC-IWF) entity (1) includes a trigger controller (11) and a notification service controller (12). The trigger controller (11) controls a device trigger of an MTC device (3) requested from an SCS entity (2). The notification service controller (12) is configured to send, to the SCS entity (2), a subscription request for a notification service including providing a PLMN (5) with management information which is collected outside (4) the PLMN (5) regarding the MTC device (3), and receive, from the SCS entity, a message containing the management information (2) when the subscription request has been accepted. Accordingly, it is possible to contribute to, for example, improvement in collaborative and cooperative operations between the PLMN and an M2M service layer.
