Counter Check in Separated Base Station Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In new network architectures, the separation of primary and secondary base stations complicates the implementation of counter check and reconfiguration processes, as existing methods rely on a single base station for both processes, leading to issues with data packet detection and security algorithm updates.
Innovation Solution
A method where the primary base station receives identity and count information from the secondary base station, extracts relevant data, and sends it to the terminal for comparison, allowing the terminal to determine counter check results, while the secondary base station performs secure communication using updated encryption algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the counter check process is applied to the new network architecture where primary and secondary base stations are separated, then the counter check function cannot be implemented because the primary base station cannot obtain count-related information
Solution Approach 1:
The secondary base station acts as an intermediary that maintains the count values and provides this information to the primary base station when needed for counter checks. This mediator role allows the primary base station to perform security verification without directly maintaining the count information, resolving the contradiction between needing count data for reliability and the architectural separation that prevents direct access.
2Reliability
If the reconfiguration process is applied to the new network architecture where primary and secondary base stations are separated, then the secondary base station cannot perform normal secure communication with the terminal because security-related information cannot be obtained
Solution Approach 1:
The patent segments the base station functions into primary base station (handling security management and reconfiguration) and secondary base station (handling data transmission and maintaining count values). This segmentation allows each entity to focus on specific tasks - the primary base station obtains security information from the core network and manages terminal security, while the secondary base station maintains count information for integrity verification, thus resolving the information access contradiction.
3Adaptability or versatility
If a single base station maintains both count values and performs secure communication, then the existing counter check and reconfiguration processes work, but the network architecture lacks flexibility and scalability
Solution Approach 1:
The patent divides the base station into primary and secondary components with distinct responsibilities. The secondary base station specializes in data transmission and count value maintenance, while the primary base station handles security management, reconfiguration, and coordination with the core network. This functional segmentation enables the network to scale and adapt to different scenarios without requiring every base station to perform all functions.

AI summary
The present invention relates to a counter check and reconfiguration method, apparatus, and system. The method includes: receiving first identity information and first count information sent by a secondary base station; querying second identity information according to the first identity information; extracting second count information from the first count information; sending the second identity information and the second count information to a terminal, so that the terminal compares, according to the second identity information, the second count information with third count information maintained by the terminal itself to obtain first comparison result information or second comparison result information; receiving the first comparison result information, or the second identity information and second comparison result information sent by the terminal; and determining counter check result information according to the received first comparison result information, or the received second identity information and second comparison result information. Thereby, the present invention implements a counter check process and a reconfiguration process in a network architecture in which a primary base station is separated from a secondary base station.
