Network Node Notification Method for Energy-Constrained Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for observing telecommunications networks require significant bandwidth and resource consumption, especially when fine observation is needed, making them unsuitable for networks with energy- and bandwidth-constrained nodes.
Innovation Solution
A notification method where devices in the network send notification messages signaling operations related to data messages, including identifiers for the device, functional entity, operation, and a common identifier for all instances of the data message within the device, allowing for asynchronous observation without disturbing data message exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If asynchronous interrogation is performed to observe all successive states of network nodes, then measurement precision is improved, but use of energy and bandwidth increases significantly
Solution Approach 1:
Instead of the network operation center actively interrogating nodes to obtain state information, the invention inverts the approach by having nodes autonomously push state change notifications to the network operation center. This inversion eliminates the need for intensive asynchronous interrogation while maintaining complete observation of all successive states, thereby resolving the contradiction between measurement precision and energy consumption.
Solution Approach 2:
The notification method enables nodes to self-report their state changes without external prompting. Each node autonomously generates and transmits notifications when state changes occur, eliminating the need for continuous external interrogation. This self-service mechanism achieves complete observation with minimal energy consumption and bandwidth usage.
2Measurement precision
If intensive interrogation is performed to observe fine details of node operations, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The notification message is segmented into distinct identifier fields (node identifier, functional entity identifier, operation identifier, data message identifier) that can be independently processed. This segmentation allows the network operation center to selectively filter and analyze only the specific state changes of interest without processing all possible interrogation data, thereby maintaining high observation precision while reducing system complexity.
3Reliability
If continuous monitoring is performed to detect all state changes, then reliability is improved, but loss of energy increases
Solution Approach 1:
Instead of continuous monitoring, the system employs event-driven periodic action where notifications are transmitted only at specific moments when state changes occur. This approach maintains complete detection reliability for all state changes while eliminating energy consumption during periods when no changes occur, effectively resolving the contradiction between reliability and energy loss.

AI summary
A notification method is performed by at least a first device of a plurality of devices forming nodes of a network. The first device is suitable for sending and/or receiving at least one data message via a first communication link to and/or from at least one second device of the plurality. The notification method is adapted to the first device transmitting at least one notification message signaling at least one predetermined operation relating to at least one instance of the data message and performed by a functional entity of the first device, the notification message including an identifier of the first device, an identifier of the functional entity, an identifier of the operation, and an identifier common to all of the instances of the data message within the first device.
