Solution Overview

Problem

The existing communication systems waste energy and resources by providing continuous air coverage to millions of base stations, leading to interference with ground terminal devices, especially when only a few UAVs require air communication services.

Innovation Solution

A wireless communication method where a terminal device reports its communication parameters, and a management device determines the target access network to provide communication coverage, enabling only necessary networks to activate their coverage functions, thus optimizing resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If air coverage capability is enabled all the time on all base stations, then UAV communication coverage is ensured, but energy and wireless transmission resources are wasted

Engineering Contradiction:
ImproveUAV communication coverageVSAvoidenergy waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements dynamic air coverage capability activation where base stations enable or disable their air coverage function based on real-time UAV detection and service requirements. The management device receives UAV communication service requirements, determines target access networks, and sends configuration messages to dynamically activate coverage only when needed, transforming the static always-on coverage model into a dynamic on-demand model that adapts to actual service needs.

Inventive Principle:
Principle #15Dynamics

2Reliability

If air coverage capability is enabled all the time on all base stations, then UAV communication coverage is ensured, but interference is caused to ground terminal devices

Engineering Contradiction:
ImproveUAV communication coverageVSAvoidinterference to ground devices
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by enabling air coverage capability only in specific base stations that are determined to be target access networks for UAV services, rather than uniformly enabling it across all base stations. The management device selectively activates coverage function based on UAV location and service requirements, creating a localized coverage pattern that provides necessary UAV service while minimizing widespread interference to ground terminal devices in other areas.

Inventive Principle:
Principle #3Local quality

3Reliability

If air coverage capability is enabled on millions of base stations, then comprehensive UAV coverage is achieved, but wireless transmission resources are wasted

Engineering Contradiction:
Improveair coverageVSAvoidwireless transmission resources waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent implements partial action by activating air coverage capability only on the minimum necessary subset of base stations that are identified as target access networks for specific UAV services. Rather than enabling coverage on all millions of base stations (excessive action), the system selectively enables it only where and when needed based on UAV communication service requirements, achieving adequate coverage with optimized resource utilization.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A wireless communication method and a communication device. The method includes: a first management device receives a communication coverage request message from a second management device, where the communication coverage request message includes at least one of the following communication parameter information: communication coverage area information and communication service requirement information; the first management device determines at least one target access network based on the communication parameter information; and the first management device sends a first configuration message to the target access network, where the first configuration message is used to indicate the target access network to provide communication coverage. This can reduce a waste of energy and resources.
