3GPP Network Access Authentication for Core Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 3GPP network architecture faces excessive load due to unauthorized access attempts from user equipment (UE) that are not permitted, leading to inefficiencies and increased processing demands on core network devices.
Innovation Solution
The proposed solution involves the UE sending an access request message to the core network device, receiving an unauthorized access message with authentication information, and performing authentication using this information to determine authorization, thereby reducing the number of access request messages sent to the core network device and implementing corresponding network access policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the core network device sends unauthorized access messages to all terminals without authentication, then the access control process is simple and fast, but the core network device experiences excessively heavy load due to continuous access attempts from unauthorized terminals
Solution Approach 1:
The terminal performs authentication on the core network device before attempting network access. This preliminary action verifies whether the terminal is authorized, preventing unauthorized terminals from continuously sending access requests to the core network device, thereby reducing the device's processing load while maintaining access control efficiency
Solution Approach 2:
The core network device provides authentication information to the terminal, and the terminal uses this information to authenticate the core network device. This feedback mechanism enables the terminal to make informed access decisions, reducing unnecessary access attempts and lowering the core network device's load
2Reliability
If the terminal continuously sends access request messages to the core network device, then the terminal ensures it can access the network if authorized, but the core network device experiences excessively heavy load from processing numerous requests
Solution Approach 1:
The terminal performs authentication on the core network device before sending access requests. This preliminary verification ensures that only authorized terminals attempt to access the network, maintaining access reliability for legitimate users while preventing unauthorized terminals from generating excessive traffic that would overload the core network device
Solution Approach 2:
The terminal autonomously authenticates the core network device using authentication information obtained from the network. This self-service capability allows the terminal to determine its own authorization status without requiring continuous core network device processing, reducing the device's load while ensuring reliable access for authorized terminals

AI summary
A processing method for terminal access to a 3GPP network is provided. UE sends an access request message to a core network device on the 3GPP network, and the core network device sends an unauthorized access message to the UE after determining that the UE has no permission to access the 3GPP network. The unauthorized access message includes authentication information of the core network device. The UE performs authentication on the core network device according to the authentication information of the core network device, and executes a corresponding network access policy after authentication on the core network device by the UE succeeds, that is, after the UE determines that a source of the unauthorized access message is authorized, to reduce a quantity of access request messages that are sent to the core network device. This reduces load of the core network device, and further can improve efficiency of accessing the 3GPP network.
