NCAP Base Station Authentication During Network Operator Failures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a mobile communication network with Network Controlled Access Points (NCAPs), authentication processing fails if a failure occurs on the network operator side, leading to potential communication failures.
Innovation Solution
A communication device (NCAP) with multiple communication units and a control unit that operates as a radio base station to accommodate terminals without specific communication with the network operator side, performing exceptional operations based on predefined conditions to maintain communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication processing is performed through the network operator side, then security and control are improved, but communication reliability deteriorates when network failures occur
Solution Approach 1:
The patent segments the authentication function into two parts: security parameter management remains with the network operator, while actual authentication processing is distributed to individual NCAPs. This segmentation allows NCAPs to perform local authentication using cached security parameters, maintaining communication reliability during network failures while preserving security control.
Solution Approach 2:
The patent implements preliminary action by having NCAPs acquire and cache security parameters from the network operator in advance, before network failures occur. This preliminary acquisition of authentication data enables NCAPs to independently perform authentication processing even when the network operator becomes unavailable, thus improving communication reliability.
2Reliability
If NCAP operates independently without network operator communication, then communication continuity is improved, but authentication security may deteriorate
Solution Approach 1:
The patent applies preliminary action by having the NCAP acquire necessary authentication data and security parameters from the network operator before independent operation begins. This preliminary data acquisition ensures that the NCAP has all required information to perform secure authentication independently, maintaining both communication continuity and authentication security.
Solution Approach 2:
The patent uses copying by creating local copies of security parameters and authentication data at the NCAP, rather than relying on real-time connection to the network operator. These copied data enable the NCAP to perform authentication processing independently while maintaining security, as the copied parameters are sufficient for verification purposes.

AI summary
A communication device performs a communication with a first communication network and a second communication network, and a radio communication with a terminal (UE 200) . The communication device performs a specific operation as a radio base station that accommodates a terminal without performing a communication with the first communication network based on whether or not a specific condition concerning the first communication network is satisfied.
