Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pseudo base stations are deployed to provide service, then user connectivity is improved, but network reliability deteriorates due to forced connections and congestion
Solution Approach 1:
The system performs preliminary actions by having the terminal device calculate and report HASH values of system broadcast information before actual connection is established. This allows the network device to identify pseudo base stations in advance and prevent forced connections, thereby maintaining network reliability while allowing legitimate pseudo base stations to provide service.
Solution Approach 2:
The system implements feedback mechanisms where the terminal device reports measurement configurations and HASH values back to the network device. This feedback loop enables the network to identify pseudo base stations and adjust connectivity decisions, resolving the contradiction between allowing service provision and preventing harmful interference.
2Difficulty of detecting and measuring
If terminal devices frequently update location to track pseudo base stations, then detection capability is improved, but network resource consumption increases causing congestion
Solution Approach 1:
The system performs preliminary calculation of HASH values at the terminal device before reporting to the network. This preliminary action reduces the amount of data that needs to be transmitted and processed by the network, thereby improving detection capability while reducing network resource consumption and avoiding congestion.
Solution Approach 2:
The system extracts only the essential HASH value information from the full system broadcast information and reports only this extracted data to the network device. This extraction approach enables effective pseudo base station detection while minimizing network resource consumption by avoiding transmission of complete location update data.
3Measurement precision
If network devices implement comprehensive measurement configurations to identify pseudo base stations, then identification accuracy is improved, but device complexity increases
Solution Approach 1:
The system extracts only the essential HASH value calculation requirement from comprehensive measurement configurations. By focusing on calculating and reporting HASH values of system broadcast information, the system achieves high identification accuracy while simplifying the measurement configuration process and reducing device complexity.
Solution Approach 2:
The system uses HASH values as a simplified copy or representation of the full system broadcast information. This copying approach allows the network to identify pseudo base stations with high accuracy using compact HASH values rather than processing complete broadcast information, thereby reducing device complexity while maintaining identification precision.

AI summary
Embodiments of the present application provide a pseudo base station recognition method and apparatus, a terminal device, and a network device. The method comprises: a terminal device receives first measurement configuration sent from a network device and reports to the network device the cell identification information of a first cell on the basis of the first measurement configuration, the cell identification information being used by the network device to determine whether the first cell is a pseudo base station cell and/or a recognized unconfigured neighboring cell; and the terminal device receives second measurement configuration sent from the network device and reports to the network device a hash value of system broadcast information of a second cell on the basis of the second measurement configuration, the hash value being used by the network device to determine whether the second cell is a pseudo base station cell.
