Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing system information verification methods in communication systems face accuracy issues due to differences in verification algorithms between user equipment (UE) and network-side devices, leading to reduced accuracy and inability to execute differentiated control based on security requirements.
Innovation Solution
The proposed solution involves a method where the user equipment (UE) sends auxiliary information to the network-side device, including verification manners and algorithms supported by the UE. The network-side device then uses this information to trigger correctness verification for system information, ensuring that both the UE and network-side device use the same verification algorithm, thereby improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the UE and network-side device use different verification algorithms for system information verification, then the verification process can be performed independently by each device, but the verification accuracy deteriorates due to algorithm inconsistencies
Solution Approach 1:
The patent changes the verification algorithm parameter from being device-specific to being standardized. The network-side device determines a verification algorithm and sends it to the UE, ensuring both devices use the same algorithm. This parameter change resolves the contradiction by maintaining independent verification capability while ensuring algorithm consistency for accurate verification.
2Reliability
If the network-side device sends verification results to the UE, then the UE can verify system information correctness, but the communication overhead and system complexity increase
Solution Approach 1:
The patent implements self-service verification where the UE performs the verification calculation itself using the verification algorithm and data provided by the network-side device. The network-side device sends the verification algorithm and system information, but the UE independently completes the verification and determines correctness. This reduces system complexity while maintaining reliable verification capability.
3Measurement precision
If the UE sends auxiliary information including verification algorithm support to the network-side device, then the verification accuracy improves through algorithm matching, but the information exchange overhead increases
Solution Approach 1:
The patent applies preliminary action by having the UE send its supported verification algorithm information to the network-side device before the actual verification process. The network-side device uses this advance information to select and send the appropriate verification algorithm that matches the UE's capabilities. This preliminary exchange enables accurate algorithm matching while minimizing subsequent communication overhead.

AI summary
System information verification methods, communication apparatuses, and storage mediums that improve security of a wireless communication network. The security is improved by: sending auxiliary information to a network-side device, wherein the auxiliary information comprises at least one of a verification manner supported by UE, information of a verification algorithm supported by the UE, an identifier of system information expected to be verified by the UE, an identifier of system information received by the UE, an identifier of system information of interest of the UE, or first indication information for indicating that the UE expects system information verification; and triggering, based on information sent by the network-side device, correctness verification for system information.
