Base Station ProSe Authentication for Core Network Failure Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face disruptions when a failure occurs between a base station and a packet core network, leading to communication disconnection between terminals, which can result in prolonged service interruptions.
Innovation Solution
A wireless communication system where the base station performs authentication and authorization using proximity-based communication services to enable direct communication between terminals, even when the connection with the packet core network is lost, by utilizing ProSe protocols and retaining communication parameters to maintain service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station maintains connection to the packet core network, then normal communication services are provided, but communication is terminated when a failure occurs between the base station and the packet core network
Solution Approach 1:
The base station performs authentication and authorization of terminals in advance using proximity-based communication services before core network connection failure occurs. This preliminary action enables the base station to independently manage terminal communications when the core network becomes unavailable, ensuring continuous service without requiring complex real-time authentication mechanisms during failure states
Solution Approach 2:
The patent introduces proximity-based communication services as an intermediary mechanism between the base station and terminals. This intermediary layer allows the base station to authenticate and authorize terminals locally without direct core network involvement during failures, bridging the gap between network infrastructure and end-user services while maintaining communication continuity
2Reliability
If the base station uses proximity-based communication services for authentication and authorization, then communication continues during core network failures, but system complexity increases
Solution Approach 1:
The base station is designed to perform multiple functions: normal core network-connected communication when available, and independent proximity-based authentication and authorization when the core network fails. This multi-functionality allows a single base station to handle both standard and isolated operation modes without requiring separate dedicated systems, managing complexity through functional integration rather than proliferation of components
3Reliability
If direct terminal communication is enabled during core network failure, then service disruption is minimized, but security control becomes more difficult
Solution Approach 1:
Authentication and authorization are performed in advance by the base station using proximity-based communication services before core network failure occurs or immediately upon detection of failure. This preliminary security control establishes trusted terminal relationships while the base station can still operate autonomously, maintaining security oversight without requiring continuous core network involvement during failure states
