Random Data Integrity Protection in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of data integrity protection in wireless user devices consumes significant battery power and degrades performance for other user tasks.
Innovation Solution
A wireless communication network provides random data integrity protection to User Equipment (UE), where a network controller selects the random integrity protection based on UE context and signals it to a wireless access node, which then randomly selects and converts data units for integrity protection, transferring both protected and unprotected data units to the UE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data integrity protection is applied to all data sessions in wireless user devices, then data security is improved, but battery power consumption increases significantly
Solution Approach 1:
The patent applies integrity protection selectively to specific data sessions rather than uniformly to all sessions. The network device determines which data sessions require integrity protection based on their security requirements, applying protection only where necessary. This local differentiation reduces the overall processing load and battery power consumption in the wireless user device while maintaining security for critical data sessions.
Solution Approach 2:
The patent implements partial integrity protection by applying it to only a subset of data sessions that require security, rather than applying it excessively to all sessions. The network device controls the application of integrity protection on a per-session basis, allowing the wireless user device to avoid unnecessary processing and power consumption for sessions that do not require protection.
2Reliability
If data integrity protection is applied to all data sessions, then data security is improved, but processing resources are consumed and performance for other user tasks degrades
Solution Approach 1:
The patent applies integrity protection selectively to specific data sessions based on their security requirements rather than uniformly to all sessions. This localized approach ensures that processing resources are consumed only for sessions that require protection, leaving sufficient resources available for other user tasks and applications.
Solution Approach 2:
The patent implements partial integrity protection by applying it only to necessary data sessions. The network device controls the application of integrity protection on a per-session basis, allowing the wireless user device to maintain adequate processing performance for other user tasks while still providing security where required.
3Reliability
If integrity protection is applied to more data units, then data integrity is improved, but the complexity of data transmission processing increases
Solution Approach 1:
The patent applies integrity protection selectively to specific data sessions based on their security requirements. The network device determines which sessions need protection and applies integrity protection only to those sessions, reducing the overall complexity of data transmission processing compared to applying protection to all sessions uniformly.

AI summary
A wireless communication network serves random data integrity protection to a User Equipment (UE). A network controller selects the random data integrity protection for a UE session based on UE context. The network control signals the random integrity protection for the UE session to a wireless access node which signals the UE. A wireless access node generates data units for an interval. The wireless access node randomly selects ones of the data units to reach a downlink amount for the interval. The wireless access node converts the selected data units into integrity-protected units. The wireless access node wirelessly transfers the unprotected data units and the integrity-protected units to the UE. The UE determines the amount of the integrity-protected data units for the interval. The UE determines data integrity of the unprotected data units based on the amount of the integrity-protected units for the interval.
