5G Radio Node Global ID Determination via Length Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication networks, the variable length of global gNB IDs poses a challenge for radio network nodes to determine the correct global ID without pre-known length, leading to issues in procedures like TNL Address Discovery.
Innovation Solution
A method is introduced where a wireless device receives length information specifying the global ID length from a second radio network node and sends it to the first radio network node, enabling the determination of the global ID based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If variable length global gNB IDs are used in 5G networks, then network flexibility and adaptability are improved, but the complexity of determining correct global ID increases
Solution Approach 1:
The patent applies preliminary action by having the second radio network node transmit length information about its global gNB ID before the actual ID determination process. This allows the first radio network node to prepare the correct extraction logic in advance, knowing the exact length of the global ID it needs to parse from subsequent messages, thereby reducing determination complexity while maintaining variable length flexibility
Solution Approach 2:
The patent introduces length information as an intermediary element that mediates between the variable length global gNB IDs and the determination process. This intermediary carries metadata about the ID length, enabling the receiving node to correctly parse the global ID without complex trial-and-error or lookup mechanisms, thus resolving the contradiction between flexibility and complexity
2Measurement precision
If pre-known length information is required for global ID determination, then determination accuracy is improved, but the need for complex configurations and look-up tables increases device complexity
Solution Approach 1:
The patent implements self-service by having the second radio network node automatically provide its own length information to the first node. This eliminates the need for external configuration databases, lookup tables, or manual setup of global ID lengths, as each node autonomously shares the necessary metadata about its identifier format, achieving high determination accuracy without increased device complexity
Solution Approach 2:
The patent changes the parameter transmission approach by dynamically conveying length information as a variable parameter rather than relying on fixed configurations. This allows the global ID length to be adapted and communicated freely between nodes without being constrained by pre-defined lookup tables or complex configuration schemes, thereby maintaining accuracy while simplifying device complexity
