Solution Overview

Problem

The current OneM2M architecture lacks flexibility in removing notification recipients and managing large numbers of recipients in Machine-to-Machine (M2M) communication systems, requiring human intervention and not supporting dynamic management of subscriptions.

Innovation Solution

Implementing a method that allows recipients to request removal from notifications based on defined removal policies, which can require approval from the subscription originator or be automatically managed, and using group management to control notification policies for multiple recipients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the current oneM2M architecture is used to manage notification recipients, then the system maintains simplicity in subscription management, but the system lacks flexibility in removing recipients and cannot easily manage large numbers of recipients

Engineering Contradiction:
Improveflexibility in removing recipientsVSAvoidsubscription management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a Common Services Entity (CSE) as an intermediary between the subscription originator and notification recipients. The CSE hosts the subscription and manages the distribution list, acting as a mediator that handles recipient addition, removal, and notification routing. This allows the subscription originator to create subscriptions without directly managing individual recipients, while recipients can be dynamically added or removed through the CSE's interface, resolving the contradiction between flexibility and complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Extent of automation

If manual management of notification recipients is implemented, then the system ensures secure control over recipient lists, but the system requires human intervention and cannot dynamically manage recipients

Engineering Contradiction:
Improvedynamic recipient managementVSAvoidsecurity control
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The patent enables dynamic management of notification recipients through automated interfaces provided by the CSE. Recipients can be added or removed programmatically using standard M2M interface references, allowing the system to adapt to changing requirements without manual intervention. The subscription originator can specify multiple recipients and manage the distribution list dynamically, while the CSE maintains security through authorized access controls, thus achieving both automation and reliability.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If multiple recipients are subscribed to notifications, then the system provides comprehensive event coverage, but the system becomes difficult to manage when dealing with large numbers of recipients

Engineering Contradiction:
Improvenumber of notification recipientsVSAvoidrecipient management ease
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent makes the Common Services Entity (CSE) a universal management point for all notification recipients in a subscription. The CSE provides a single interface for managing the entire distribution list, regardless of the number of recipients. This universal management approach allows the subscription originator to add, remove, or modify multiple recipients through a consistent interface, making the system scalable and easy to operate even with large numbers of recipients.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Systems and methods for flexibly and securely enabling removal of event notification recipients are disclosed. More specifically, embodiments of a method of operation of a node in a M2M communication system to enable removal of a notification recipient are disclosed. In some embodiments, the method of operation of the node comprises sending a notification of an event to one or more recipients. The one or more recipients are subscribed to notifications of the event by a subscription originator and are different than the subscription originator. The method further comprises receiving a removal request from a recipient, determining whether removal of the recipient as a recipient of notifications of the event is permitted based on a removal policy for the recipient, and removing the recipient as a recipient of notifications of the event upon determining that removal of the recipient as a recipient of notifications of the event is permitted.
