Roaming UE Analytics Configuration via Trust Surveillance Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack the ability for a Home Public Land Mobile Network (HPLMN) to configure User Equipment (UE) roaming in a Visited Public Land Mobile Network (VPLMN) to perform service- and performance-specific measurements in a transparent manner, preventing secure reporting of analytics to the home network.
Innovation Solution
The proposed solution involves an apparatus comprising a transceiver and a processor configured to receive a monitoring configuration request from a trust surveillance network function. This apparatus selects a UE registered in the VPLMN and sends a monitoring configuration message to the UE, which then performs specified parameter set monitoring and sends monitoring results reports securely to an application function in the HPLMN.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the HPLMN configures UE to perform measurements in VPLMN, then analytics can be collected securely, but the VPLMN network transparency is compromised
Solution Approach 1:
The patent introduces a Trust Surveillance Network Function as an intermediary between the HPLMN and VPLMN. This mediator enables the HPLMN to configure UE measurements without direct visibility into VPLMN operations, maintaining VPLMN transparency while ensuring secure analytics collection. The intermediary handles configuration and verification indirectly, allowing HPLMN to monitor without compromising VPLMN network transparency.
2Measurement precision
If the UE performs service-specific measurements in roaming network, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The Trust Surveillance Network Function performs preliminary actions by pre-configuring measurement parameters and service information before the UE actually performs measurements. The system prepares measurement configurations, service lists, and monitoring parameters in advance, so when the UE executes measurements, it simply follows pre-established guidelines rather than making real-time decisions, reducing UE processing complexity while maintaining measurement precision.
3Reliability
If the HPLMN implements monitoring of roaming UEs, then network security is improved, but loss of information increases
Solution Approach 1:
The patent extracts critical monitoring information from the full UE context by selectively collecting only the necessary parameters for trust surveillance. Instead of monitoring all UE data, the system extracts specific measurement results, service information, and configuration parameters that are relevant for security assessment. This selective extraction approach maintains network security while minimizing information loss and reducing data handling overhead.
