Radio Bearer Integrity Control to Reduce 5G Terminal Processing Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The implementation of integrity protection and verification functions in next-generation mobile communication systems leads to increased data processing complexity and load, which can slow down data processing speed and require efficient methods to manage these functions effectively.
Innovation Solution
A method and apparatus are provided to dynamically configure and manage the integrity protection and verification functions for radio bearers, allowing selective application based on the requirements of each bearer, using RRC messages and indicators to control the activation or deactivation of these functions, thereby reducing unnecessary processing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If integrity protection function or integrity verification function is configured and used to enhance data security, then security is improved, but data processing speed decreases and data processing load increases
Solution Approach 1:
The patent applies dynamics by enabling flexible activation and deactivation of integrity protection and verification functions through RRC message configuration. The system can dynamically adjust the security level based on service requirements, allowing high-speed data transmission when security is not critical and enhanced security when needed, thus resolving the contradiction between security and processing speed
Solution Approach 2:
The patent implements local quality by applying integrity protection and verification functions selectively to specific radio bearers based on their security requirements. Different bearers can have different security configurations - some with full integrity protection, others without - allowing the system to maintain security for critical data while processing non-critical data at high speed without unnecessary security overhead
2Reliability
If integrity protection function or integrity verification function is configured and used to enhance data security, then security is improved, but data processing load increases
Solution Approach 1:
The patent reduces device complexity by applying integrity protection and verification functions selectively to specific radio bearers rather than uniformly to all bearers. The network can configure each bearer individually based on security requirements, so that only bearers needing security undergo the complex integrity checking process, while others bypass it entirely, reducing overall processing load
Solution Approach 2:
The patent enables dynamic configuration of integrity protection functions through RRC messages, allowing the system to adapt security levels to actual needs. This flexibility prevents unnecessary processing overhead by activating security functions only when and where required, thereby reducing the overall data processing load on the device
3Reliability
If integrity protection function is applied to all radio bearers, then security coverage is improved, but processing efficiency decreases
Solution Approach 1:
The patent implements differentiated security policies for different radio bearers based on their specific requirements. Critical bearers such as those carrying control plane data receive full integrity protection, while bearers carrying non-critical user data may have integrity protection disabled or reduced, thereby maintaining security coverage for essential functions while preserving processing efficiency for bulk data transmission
