Paging Message Security Negotiation for Unauthorized Base Station Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing paging message processing technologies in communications systems lack effective security measures, making them vulnerable to unauthorized base stations, which can lead to unpredictable losses and failures of operator-configured policies.
Innovation Solution
A method and apparatus for enhancing the security of paging messages by allowing terminals and network-side devices to negotiate and enable or disable security protection, including encryption and digital signing, based on capability information exchanged between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security protection is enabled for paging messages, then security against unauthorized base stations is improved, but device complexity increases due to capability negotiation and configuration mechanisms
Solution Approach 1:
The terminal sends capability information about security protection in advance before the actual paging message reception. This preliminary capability exchange allows the network to pre-configure security parameters, avoiding complex real-time negotiations during the critical paging reception phase and thus managing device complexity while maintaining security.
Solution Approach 2:
The patent implements dynamic security protection where the network can enable or disable security based on the terminal's capability information and network conditions. This dynamic adjustment allows the system to adapt security levels according to actual needs, balancing security improvement with operational simplicity.
2Adaptability or versatility
If capability information exchange is implemented between terminal and network, then security protection flexibility is improved, but signaling overhead increases
Solution Approach 1:
Instead of exchanging complete security protocol details and all possible capability parameters, the terminal sends only the necessary capability information (such as supported security algorithms and preferences). This partial action approach provides sufficient flexibility for security configuration while minimizing signaling overhead by excluding unnecessary detailed information.
Data Source
AI summary
A paging message processing method and apparatus, a communications device, and a readable storage medium. The method includes: sending, by a terminal, capability information related to security protection of a paging message; and receiving, by the terminal, configuration information, where the configuration information is used to enable or disable security protection for the paging message.
