Network Element Authenticator Relocation Request Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadband wireless communication networks face increased complexity and potential safety hazards due to simultaneous authenticator relocation and re-authentication processes, leading to inefficient processing and context management.
Innovation Solution
A method and system that refuse new authenticator relocation or re-authentication requests when initial authentication, re-authentication, or authenticator relocation is ongoing, using state identifiers, counters, or timers to determine the status and prevent concurrent processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network accepts multiple authenticator relocation requests simultaneously, then the system becomes more responsive to relocation needs, but the processing complexity and safety hazards increase
Solution Approach 1:
The patent applies preliminary anti-action by introducing a locked state that prevents new authenticator relocation requests from being accepted when a relocation process is already ongoing. This preemptive blocking mechanism avoids the complexity of handling concurrent processes by refusing them before they can initiate, thereby maintaining system simplicity while still responding to relocation needs when appropriate.
Solution Approach 2:
The patent implements preliminary action by setting the locked state before the relocation process completes. By establishing this preventive measure in advance (when the relocation is initiated), the system avoids the need to manage complex concurrent state transitions and context switching, thus reducing processing complexity while maintaining responsiveness to legitimate relocation requests.
2Productivity
If the network element maintains multiple sets of contexts for concurrent processes, then more operations can be handled simultaneously, but safety hazards and processing complexity increase
Solution Approach 1:
The locked state mechanism serves as a preliminary anti-action that prevents potentially unsafe concurrent operations. By blocking new relocation requests during an ongoing process, the system eliminates the safety hazards associated with maintaining multiple contexts without sacrificing overall productivity, as legitimate sequential operations are still permitted.
3Reliability
If re-authentication is performed during authenticator relocation, then authentication security is maintained, but the processing complexity increases
Solution Approach 1:
The patent applies preliminary anti-action by preventing new relocation requests (which would trigger additional re-authentication) during an ongoing relocation process. This approach maintains authentication security by ensuring proper authentication flow while avoiding the complexity of managing nested or concurrent authentication processes.
Data Source
AI summary
The disclosure provides a method and a system for processing an authenticator relocation request. When detecting that initial authentication, re-authentication or authenticator relocation is being performed for a terminal, a network side refuses a new authenticator relocation request from the terminal. When detecting that no initial authentication, re-authentication or authenticator relocation is being performed for the terminal, the network side accepts the new authenticator relocation request from the terminal. Further, when detecting that the initial authentication, the re-authentication or the authenticator relocation is being performed for the terminal, the network side refuses a new re-authentication request from the terminal. According to the technical solution of the disclosure, the complexity of network element processing is reduced and potential safety hazard is avoided.
