UAV Controller Pairing via NAS Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of effective solutions for registering unmanned aerial vehicles (UAVs) and their controllers to a core network for long-distance communication, as near-field communication methods like WiFi are insufficient for the requirements of UAVs flying under the control of a controller.
Innovation Solution
A network registration method and apparatus that generates and sends Non-Access Stratum (NAS) signaling to a core network, including identity information of both the UAV and its controller, to request pairing registration, utilizing mobile cellular networks for long-distance communication, and allows for registration and de-registration processes through attach and attach cancellation requests.

Engineering Contradiction Analysis
1Length of moving object
If near-field communication modes like WiFi are used for UAV communication, then short-distance communication is achieved, but long-distance communication requirement cannot be met
Solution Approach 1:
The UAV and controller are registered with the core network to enable multiple communication modes. The system can switch between near-field communication (WiFi) for short-distance and mobile cellular network for long-distance communication, making the communication system universal and adaptable to different distance requirements
2Reliability
If a separate pairing registration process is implemented for UAVs, then registration functionality is achieved, but network resources are consumed
Solution Approach 1:
The pairing registration process is merged with the existing attach process. When the UAV or controller performs network attachment, it simultaneously completes pairing registration by including pairing information in the attach request message. This combines two functions into one process, avoiding additional signaling and saving network resources
3Productivity
If pairing information is included in NAS signaling, then registration efficiency is improved, but signaling complexity increases
Solution Approach 1:
The existing NAS signaling messages (attach request, attach cancel request) are made multi-functional by incorporating pairing registration capabilities. The same signaling messages used for network attachment also carry pairing information, eliminating the need for separate pairing signaling and reducing overall signaling complexity

AI summary
A network registration method includes: generating first non-access stratum (NAS) signaling, the first NAS signaling comprising first identity identifier information concerning a first user device and second identity identifier information concerning a second user device, wherein when the first user device is an unmanned aerial vehicle, the second user device is an unmanned aerial vehicle controller, and when the first user device is an unmanned aerial vehicle controller, the second user device is an unmanned aerial vehicle; and sending the first NAS signaling to a core network to request for registration of pairing information concerning the unmanned aerial vehicle and the unmanned aerial vehicle controller.
