Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no effective solution for pairing Unmanned Aerial Vehicles (UAVs) with their controllers through mobile cellular networks for long-distance communication.
Innovation Solution
The UAV and UAV controller are paired through a core network using attach request and accept signaling, with the pairing request message contained in attach request signaling and the pairing response message in attach accept signaling, leveraging the mobile cellular network's wide coverage for long-distance communication.

1Length of moving object
If UAV and controller are paired through mobile cellular network, then long-distance communication requirement is met, but pairing implementation complexity increases due to lack of effective solutions
Solution Approach 1:
The patent combines the pairing process with the attach process by integrating pairing request messages into attach request signaling and pairing response messages into attach accept signaling. This merging eliminates the need for separate pairing procedures, reducing implementation complexity while enabling long-distance communication through the mobile cellular network
Solution Approach 2:
The attach signaling is given dual functionality: it performs both network attachment and device pairing operations. The attach request signaling carries pairing request information, and attach accept signaling carries pairing response information, allowing a single signaling mechanism to serve multiple purposes and simplifying the overall system complexity
2Reliability
If separate pairing process is implemented, then pairing functionality is achieved, but network resources are consumed with additional transmission processes
Solution Approach 1:
The patent merges the pairing process with the attach process, so that pairing request and response messages are transmitted within the existing attach signaling framework. This eliminates separate transmission processes for pairing, reducing network resource consumption while maintaining reliable pairing functionality through the integrated approach

AI summary
The present invention relates to a user device pairing method and apparatus. The method comprises: receiving a pairing request message, carrying a first identity identifier, sent by a first user device, the first user device being an unmanned aerial vehicle or an unmanned aerial vehicle controller; sending a query request message carrying the first identity identifier to an unmanned aerial vehicle traffic management (UTM); receiving a query response message which comprises a query result and is fed back by the UTM; when the query result comprises a second identity identifier of a second user device in a correlation between an unmanned aerial vehicle and an unmanned aerial vehicle controller, sending to the first user device a pairing response message carrying the second identity identifier, 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..
