UE Lawful Intercept Configuration for Non-Terrestrial Roaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face inefficiencies in complying with varying lawful intercept (LI) regulations across different countries, particularly for roaming devices in non-terrestrial networks, leading to increased network traffic and performance degradation due to the need for extensive message signaling and differential network element configurations.
Innovation Solution
A user equipment (UE) device proactively identifies the jurisdiction's LI requirements by querying a home network for modified operating procedures, using a LI modify parameter table stored in its memory, reducing the need for extensive message signaling by directly implementing LI compliance during initial registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive message signaling is used for LI compliance in roaming devices, then LI regulatory compliance is achieved, but network traffic increases and performance degrades
Solution Approach 1:
The patent applies preliminary action by having the UE proactively identify jurisdiction and determine LI requirements before actual communication occurs. The UE queries the home network for modified operating procedures in advance and receives LI configuration parameters during initial registration, eliminating the need for extensive subsequent message signaling. This upfront preparation resolves the contradiction by achieving compliance without continuous network traffic.
2Reliability
If differential network element configurations are implemented for LI compliance, then LI regulatory compliance is achieved, but device complexity and configuration overhead increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting UE operating parameters based on jurisdiction-specific LI requirements. Instead of implementing complex differential configurations, the network provides modified operating procedure parameters (such as encryption settings, signaling formats) that the UE applies directly. This resolves the contradiction by achieving compliance through simple parameter adjustment rather than complex configuration changes.
