Network Authentication Control for Load Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G and other cellular systems, natural disasters, network congestion, or device failures can lead to a large number of concurrent authentication requests, overwhelming the access and application networks, causing network overload and potential disconnections or session drops.
Innovation Solution
The solution involves selectively skipping certain authentication operations, allowing terminals to use network services after authenticating with only one of the access or application networks, rather than both, under high-load conditions, and using relay nodes to coordinate authentication across multiple nodes, reducing the load on authentication nodes and increasing network robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals authenticate with both access network and application network, then security and reliability are improved, but network load and authentication complexity increase
Solution Approach 1:
The patent implements selective authentication where terminals only need to authenticate with one network (access or application) rather than both, reducing authentication complexity while maintaining security through conditional logic and network coordination mechanisms
2Reliability
If all authentication requests are processed normally, then authentication completeness is maintained, but network overload occurs during high-load conditions
Solution Approach 1:
During high-load conditions, the system selectively processes only necessary authentication requests by skipping redundant authentication operations, allowing the network to handle critical communications while reducing overall authentication load
Solution Approach 2:
The authentication system dynamically adjusts its behavior based on network load conditions, transitioning between full authentication mode and selective authentication mode to optimize network throughput while maintaining essential service availability
3Reliability
If dual authentication is required, then security is enhanced, but service availability during high-load conditions decreases
Solution Approach 1:
The system performs only the necessary authentication operation (either access network or application network authentication) rather than both, maintaining security through conditional logic while improving service availability during high-load conditions

AI summary
In some examples, an authentication node of a telecommunications network can receive an authentication request from a terminal, and an authentication-control message. The authentication node can skip an authentication operation with respect to the authentication request in response to the authentication-control message. In some examples, a relay node of the telecommunications network can detect an overload or service-interruption condition and determine, in response, the authentication-control message. The relay node can send the authentication-control message to the authentication node. In some examples, an authentication node can detect that its load level satisfies a predetermined criterion and, in response, skip an authentication operation and send a first message. Another authentication node can receive an indication of the first message and, in response, perform a second authentication operation.
