M2M Event Notification Platform Subscription Consolidation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current European Telecommunications Standards Institute (ETSI) M2M framework lacks support for application-related events, leading to inefficient management of subscriptions and increased network congestion as the volume of transmitted information grows, as it is transparent to the content and semantics of the data, failing to provide value-added services.
Innovation Solution
Implementing a subscription control method and communications node that manages subscriptions to application events by determining if other devices are subscribed, reading and storing binding information, and transmitting messages efficiently to reduce network congestion through an Event Notification Platform that understands data syntax and semantics, thereby optimizing signaling and resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the M2M framework processes all subscription requests individually without checking existing subscriptions, then each user receives their own notification messages, but network congestion increases and signaling efficiency decreases
Solution Approach 1:
The patent merges multiple subscription requests for the same application event into a single subscription message sent to the application server. The subscription management entity detects when multiple users subscribe to the same event and consolidates their requests, sending one notification message that is then distributed to all subscribed users. This reduces the total number of signaling messages in the network while ensuring all users receive notifications.
Solution Approach 2:
The patent implements preliminary checking of existing subscriptions before processing new subscription requests. The subscription management entity maintains a record of active subscriptions and checks this record when a new subscription request arrives. This preliminary action prevents duplicate subscription messages from being sent to the application server and enables the merging of concurrent subscription requests for the same event.
2Reliability
If the system sends notification messages to all users for every event, then all subscribed users receive notifications, but unnecessary signaling occurs and network resources are wasted
Solution Approach 1:
The patent combines multiple notification deliveries for the same event into a single message transmission to the application server. By consolidating subscription requests and sending one notification message that is distributed to all subscribed users, the system maintains complete notification delivery while minimizing network resource consumption and eliminating redundant signaling.
3Adaptability or versatility
If the M2M framework does not understand data syntax and semantics, then the system remains transparent and simple, but value-added services and application-related event support cannot be provided
Solution Approach 1:
The patent introduces an event notification platform as an intermediary layer between the transparent M2M framework and application-specific processing. This platform subscribes to application events, understands their syntax and semantics, and manages the subscription consolidation logic. The underlying framework remains transparent and simple, while the intermediary enables value-added services by processing application-related events and coordinating notification distribution to subscribed users.

AI summary
Systems and methods provide for managing subscriptions to changes in resources in a Machine-to-Machine (M2M) system at a communications node. A method for such includes receiving, at an interface, a first subscription request from a first user to an application event; determining, by a processor, if other devices are subscribed to the application event; reading, by the communications node, the first subscription request including data, semantics and syntax; storing, in a memory, binding information for the first user and the application event; and transmitting, by the interface, if, based on said step of determining, no other devices are subscribed to the application event a second subscription message toward an M2M application server (AS).
