M2M Periodic Notification Subscription Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Machine-to-Machine (M2M) systems, existing technologies face challenges in efficiently transmitting and receiving periodic notifications regardless of resource changes, leading to inefficiencies in communication and resource management.
Innovation Solution
A method and apparatus for transmitting and receiving periodic notifications in M2M systems, where a subscription request message requests periodic notifications for specific resources, and notification messages are sent based on predefined start and end times and intervals, regardless of resource changes, utilizing a subscription resource with attributes that define the notification policy and schedule.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If periodic notification is transmitted only when resource changes occur, then notification traffic is reduced, but periodic monitoring capability is lost
Solution Approach 1:
The patent implements periodic notification transmission by introducing a notification counter that increments with each notification event and compares against a predefined threshold. When the counter reaches the threshold, a notification is transmitted and the counter is reset. This periodic action mechanism ensures systematic monitoring at regular intervals while consuming minimal resources, resolving the contradiction between reducing notification traffic and maintaining periodic monitoring capability.
2Reliability
If periodic notification is transmitted regardless of resource changes, then periodic monitoring capability is ensured, but notification traffic increases
Solution Approach 1:
The patent dynamically adjusts the notification transmission behavior by changing the state of a notification counter parameter. The counter value determines whether to transmit notifications based on periodic intervals rather than continuous resource change detection. This parameter-based control mechanism enables the system to maintain reliable periodic monitoring while significantly reducing unnecessary notification traffic compared to transmitting every resource change.
3Adaptability or versatility
If new resource definitions are created for periodic notification, then notification functionality is enhanced, but system complexity increases
Solution Approach 1:
The patent achieves enhanced notification functionality using existing M2M resource definitions and subscription mechanisms rather than creating new resource types. The solution reuses the established subscription request message format and notification message structure, adding only a notification counter parameter to existing resources. This universal approach maintains notification versatility while avoiding the complexity increase that would result from defining new resources.
Solution Approach 2:
The patent enables the system to manage periodic notifications using existing M2M framework capabilities without requiring new resource definitions or procedures. The notification counter and periodic transmission logic are implemented within the existing subscription and notification infrastructure, allowing the system to serve itself using already-available mechanisms rather than requiring additional complex resource definitions.

AI summary
A method and apparatus are configured to receive and transmit a periodic notification in a machine-to-machine (M2M) system. The method includes steps of: receiving a subscription request message requesting a periodic notification for a specific resource from an M2M entity; and periodically transmitting a notification message to the M2M entity according to the subscription request message, wherein the notification message is periodically transmitted irrespective of whether the specific resource changes.
