5G User Plane Data Integrity Protection via Selective Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks, high data rate user plane data integrity protection causes processing overload and potential service disruption due to high power consumption and transmission delay, with existing methods unable to handle data rates beyond defined limitations.
Innovation Solution
A method for configuring integrity protection settings and parameters in mobile communication devices and core network entities, which involves calculating and sending Message Authentication Codes (MAC-I) for user plane data, and deciding whether to perform integrity checks based on data rate, processing load, or importance, to optimize processing load and avoid service disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If integrity protection is applied to user plane data at high data rates, then data security is improved, but processing load and power consumption increase causing service disruption
Solution Approach 1:
The patent divides user plane data into multiple segments and applies integrity protection selectively to only certain segments (e.g., control plane data, important user data) rather than all data. This segmentation allows the system to maintain security for critical information while reducing the overall processing load and power consumption associated with integrity checks.
Solution Approach 2:
The patent implements partial integrity protection where MAC-I is calculated only for a subset of user plane data based on configured parameters and data importance. This partial action approach maintains adequate security levels while avoiding the excessive processing burden of applying integrity protection to all data at high data rates.
2Reliability
If integrity protection is applied to user plane data, then data integrity is improved, but transmission delay increases
Solution Approach 1:
By segmenting data and applying integrity protection only to critical segments, the patent reduces the total time required for MAC-I calculation and verification, thereby lowering transmission delay while maintaining data integrity for essential information.
Solution Approach 2:
The selective application of integrity protection to only necessary data portions reduces the computational overhead and processing time, directly decreasing transmission delay while preserving data integrity where most needed.
3Productivity
If maximum data rate limitation is defined for integrity protection, then processing overload is avoided, but services requiring high data rates cannot be supported
Solution Approach 1:
The patent introduces dynamic adaptation mechanisms where the system can adjust integrity protection parameters (such as the proportion of data requiring MAC-I calculation) based on current data rates, service requirements, and network conditions. This allows the system to support high data rate services while maintaining processing capacity through flexible parameter configuration.
Solution Approach 2:
The patent enables parameter changes in integrity protection configuration, allowing the network to adjust protection levels, MAC-I calculation frequency, and data segment selection based on service type and data rate requirements. This parameter flexibility allows high data rate services to be supported without overwhelming processing capacity.
