Mobile Equipment 5G Location Data Transformation for Legacy UICC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-5G Universal Integrated Circuit Cards (UICC) cannot store or handle 5G specific information, leading to interoperability failures between Mobile Equipment (ME) and UICC in 5G-capable User Equipment (UE), especially when operating in 5G New Radio (NR) networks.
Innovation Solution
The ME determines if the UICC supports a first RAT (like 5G NR) and uses a data object for a second RAT (like 4G LTE) to accommodate location information by transforming it according to specific rules, ensuring compatibility and handling 5G specific information explicitly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a non-5G UICC is used in a 5G-capable UE, then the UE can operate in 5G networks, but the UICC cannot store or handle 5G specific information causing interoperability failures
Solution Approach 1:
The patent introduces an intermediary mechanism where the ME transforms 5G location information into a format compatible with the non-5G UICC's data objects. The ME acts as a mediator that converts 5G-specific information (first RAT) into 4G-compatible formats (second RAT) before storing in the UICC, thereby enabling interoperability without requiring 5G-capable UICC hardware.
Solution Approach 2:
The patent applies parameter changes by transforming the format and structure of location information data objects. The ME modifies parameters such as data object type indicators, location information formats, and RAT-specific fields to convert 5G information into 4G-compatible representations that the non-5G UICC can store and process reliably.
2Loss of information
If 5G specific location information is stored directly in a non-5G UICC, then 5G information can be preserved, but the UICC data object structure cannot accommodate it
Solution Approach 1:
The patent transforms 5G location information parameters into 4G-compatible formats. The ME changes data object parameters including type indicators, information elements, and structural organization to match non-5G UICC requirements while preserving the essential location information content through systematic parameter transformation.
Solution Approach 2:
The patent creates transformed copies of 5G location information that are adapted for non-5G UICC storage. Instead of storing original 5G formats, the ME generates modified copies with adjusted parameters and structures that maintain the core location data while conforming to legacy UICC data object specifications.
3Reliability
If the ME transforms location information for compatibility, then interoperability is improved, but processing complexity increases
Solution Approach 1:
The patent implements systematic parameter transformation rules that the ME applies to convert 5G location information into 4G-compatible formats. This involves changing data object parameters, information element structures, and RAT-specific fields according to defined transformation protocols, enabling automated processing while ensuring interoperability.
Solution Approach 2:
The patent applies transformation rules in advance before storing location information in the UICC. The ME performs preliminary transformation of 5G location data into 4G-compatible formats prior to storage, ensuring that the UICC receives pre-processed, compatible data structures rather than requiring complex real-time conversion during retrieval or processing.
Data Source
AI summary
A User Equipment (UE) including a Universal Integrated Circuit Card (UICC) and a Mobile Equipment (ME) is provided. The ME is coupled to the UICC, and is configured to determine whether the UICC supports a first RAT in response to the UE operating in a cell which utilizes the first RAT, and use a data object for a second RAT to accommodate location information for the first RAT in response to the UICC not supporting the first RAT.
