UAV Access Control via MME Identity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular networks face challenges in controlling and securely accessing Unmanned Aerial Vehicles (UAVs), leading to potential interference and reliability issues.
Innovation Solution
A method and device for UAV access that involves an MME (Mobility Management Entity) receiving an attach request from a UAV, verifying the user's identity and device identity using IMSI and IMEI, and responding with either access allowance or rejection to prevent unauthorized access and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a UAV is allowed to access the cellular network without verification, then the application range of UAVs is expanded, but strong interference is brought to the cellular network
Solution Approach 1:
The patent applies preliminary action by performing identity verification and authentication procedures before allowing UAV access to the cellular network. The MME verifies the UAV's identity and device identity in advance, and only after successful verification does the system permit network access. This prevents unverified UAVs from causing interference while still allowing legitimate UAVs to access the network, thus resolving the contradiction between expanding application range and preventing harmful interference.
2Reliability
If identity verification is performed for UAV access, then security and reliability are enhanced, but device complexity increases
Solution Approach 1:
The patent applies universality by utilizing the existing cellular network's identity verification mechanisms (IMSI, IMEI) that are already in place for traditional mobile devices. The MME reuses existing authentication protocols and database structures to verify UAV identities, rather than creating entirely new verification systems. This approach enhances security and reliability while minimizing the increase in device complexity, as the verification process leverages already-deployed network infrastructure and protocols.

AI summary
An unmanned aerial vehicle access method and device, used for an MME. Said method comprises: receiving an access request message sent by an unmanned aerial vehicle; verifying, according to the access request message, the identity of a user using the unmanned aerial vehicle and the device identity of the unmanned aerial vehicle, to obtain a verification result; if the verification result shows that the verification succeeds, granting the access of the unmanned aerial vehicle and sending to the unmanned aerial vehicle a first access response message for indicating the acceptance of access; and if the verification result shows that the verification fails, denying the access of the unmanned aerial vehicle and sending to the unmanned aerial vehicle a second access response message for indicating the denial of access. Thus, the present invention can prevent an unmanned aerial vehicle which has not been successfully verified from accessing a cellular network, thereby reducing interference to the cellular network, improving the reliability of unmanned aerial vehicle access, helping to provide a customized service to an unmanned aerial vehicle which has been successfully verified, and improving the working efficiency of the unmanned aerial vehicle.
