UAV Capability Query During Base Station Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in rapidly acquiring and providing UAV capability information during handovers between base stations, leading to delayed response times and reduced system performance in offering UAV services.
Innovation Solution
The method involves a first base station sending a UAV capability information query request to a network management device during handovers, allowing the target base station to quickly acquire UAV capability information, thereby enhancing response speed and system performance in providing UAV services by utilizing existing signaling interactions, such as X2 interface-based path switching, without adding new signaling.

Engineering Contradiction Analysis
1Speed
If the target base station acquires UAV capability information through traditional signaling methods during handover, then the information can be obtained, but the response speed is slow and system performance is reduced
Solution Approach 1:
The source base station performs preliminary actions by obtaining the UAV capability information of the terminal before handover occurs, and includes this information in the handover request message sent to the target base station. This allows the target base station to have the capability information ready before the handover is executed, eliminating the need for separate information acquisition and reducing handover time.
2Loss of information
If additional signaling interactions are added to transmit UAV capability information, then the information can be transmitted, but the system complexity increases and resources are consumed
Solution Approach 1:
The patent merges the UAV capability information transmission with the existing handover signaling process. The capability information is included within the handover request message and handover request acknowledgment message that are already part of the standard handover procedure. This combining approach ensures complete information transmission without adding separate signaling interactions, thereby reducing system complexity and conserving resources.

AI summary
Disclosed is an unmanned aerial vehicle (UAV) capability information transmission method, which belongs to the technical field of wireless communications. The method comprises: when a terminal switches from a second base station to a first base station, the first base station sending a UAV capability information query request to a network management device; the network management device querying UAV capability information of the terminal according to the UAV capability information query request; and the network management device sending the UAV capability information to the first base station. The present disclosure realises that in the process of switching a terminal from one base station to another, a target base station to be switched to can quickly acquire UAV capability information of the terminal, so that the reaction speed of the target base station providing a UAV service for the terminal is shortened as much as possible, and the system performance of a wireless communication system providing the UAV service for the terminal is improved.
