Distributed NF Configuration Links for Stable Wireless Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks face inefficiencies and single points of failure in propagating configuration updates due to centralized systems, which can lead to network instability and reduced performance.
Innovation Solution
A decentralized approach is implemented where network functions (NFs) are grouped and configured to propagate configuration updates in a distributed manner, using established routing paths based on factors like latency, redundancy, and geography, allowing updates to be applied selectively and efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized system is used for propagating configuration updates, then configuration management is simplified and centralized control is achieved, but single points of failure are created and network stability is reduced
Solution Approach 1:
The patent segments the centralized configuration management system into distributed Network Function (NF) groups. Each NF group independently manages and propagates configuration updates within its group, eliminating the single point of failure while maintaining organized control. The segmentation divides the network into autonomous units that can operate independently.
Solution Approach 2:
The patent introduces a hierarchical dimension to configuration propagation by establishing configuration routing paths that span multiple NF groups. Configuration updates propagate vertically through designated NFs across different groups, adding a dimensional layer to the distributed architecture that maintains oversight while preserving autonomy.
2Stability of the object's composition
If configuration updates are propagated to all network functions simultaneously, then consistent configuration is achieved, but network performance degrades and update propagation becomes inefficient
Solution Approach 1:
The patent applies local quality by allowing each NF group to receive and apply configuration updates independently based on its specific needs and characteristics. Rather than uniform propagation to all NFs, each group processes updates locally, maintaining necessary consistency while optimizing for group-specific performance requirements.
Solution Approach 2:
The patent implements partial action by propagating configuration updates only to the specific NF groups that require them, rather than forcing updates on all NFs. This selective propagation reduces unnecessary processing and network overhead while maintaining configuration consistency where needed.
3Reliability
If configuration updates are propagated through multiple NF groups, then comprehensive coverage is achieved, but propagation latency increases and update speed decreases
Solution Approach 1:
The patent implements preliminary action by pre-establishing configuration routing paths between NF groups before configuration updates are needed. These predefined paths optimize the propagation route in advance, allowing configuration updates to traverse multiple NF groups quickly without real-time routing calculations, thus reducing propagation latency.
Solution Approach 2:
The patent introduces intermediary NFs that act as designated configuration propagation points between NF groups. These intermediary NFs receive configuration updates and efficiently distribute them to target groups, reducing the time required for updates to traverse the entire network by consolidating propagation through strategic intermediate nodes.

AI summary
A system described herein may identify a plurality of configurable parameters associated with Network Functions (“NFs”) of a wireless network; identify a link between a first parameter, associated with a first NF of the plurality of NFs, and a second parameter associated with a second NF of the plurality of NFs; indicate, to first NF and/or the second NF, the link between the first parameter and the second parameter; and output a configuration update to the first NF, where the configuration update includes a particular value for the first parameter associated with the first NF. The second NF may receive an indication of the configuration update and modify, based on receiving the indication of the configuration update and further based on the link between the first parameter and the second parameter, the second parameter based on the particular value.
