Inter-Node Communication Using Proxy-Based NTN Configuration Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-terrestrial network (NTN) communications systems, the presence of multiple moving network nodes results in significant overhead and complexity due to frequent updates of configuration information, leading to increased signaling load and processing demands on the access and mobility management function (AMF).
Innovation Solution
Introduce a proxy node that manages configuration information for a group of NTN nodes, distributing and updating this information efficiently to reduce signaling overhead and complexity by acting as an endpoint for multiple nodes, thereby simplifying the communication process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration information is frequently updated for multiple moving NTN nodes, then communication performance is maintained, but signaling overhead and processing complexity increase significantly
Solution Approach 1:
A proxy node is introduced as an intermediary between the AMF and multiple NTN nodes. The proxy node receives configuration information from the AMF and distributes it to multiple NTN nodes, thereby reducing the signaling burden on the AMF while maintaining effective configuration updates across all nodes.
Solution Approach 2:
The configuration distribution function is segmented from the AMF and assigned to a dedicated proxy node. This segmentation allows the AMF to focus on core network functions while the proxy node handles the complex task of distributing configuration information to multiple moving NTN nodes.
2Adaptability or versatility
If configuration information is distributed to multiple third nodes, then communication coverage is expanded, but processing demands on the AMF increase
Solution Approach 1:
The proxy node serves as a mediator that handles the distribution of configuration information to multiple third nodes (NTN nodes). This intermediary approach expands communication coverage without directly increasing the processing demands on the AMF, as the proxy node assumes this responsibility.
Solution Approach 2:
The proxy node creates and distributes copies of configuration information to multiple third nodes. This copying mechanism allows the configuration to be efficiently replicated across the network without requiring the AMF to process each individual distribution separately.
3Adaptability or versatility
If multiple moving network nodes are supported, then network flexibility is improved, but configuration management complexity increases
Solution Approach 1:
The proxy node acts as a dedicated intermediary for configuration management, handling the complexity of managing multiple moving network nodes. This allows the network to maintain flexibility in supporting mobile NTN nodes while the proxy node centralizes the configuration management tasks.
Solution Approach 2:
The proxy node performs preliminary actions by receiving configuration information from the AMF before distributing it to multiple third nodes. This preliminary receipt and processing of configuration information simplifies the overall management process by preparing and organizing the configuration data in advance.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may receive, from a second node, configuration information associated with a configuration of the second node. The first node may provide, for at least one third node, at least a portion of the configuration information, such that the at least the portion of the configuration information is distributed to a plurality of third nodes that are associated with the second node. Numerous other aspects are described.
