Solution Overview

Problem

Current communication systems face challenges in efficiently querying and identifying terminal devices within specific areas, particularly for unmanned aerial vehicles (UAVs) flying in designated areas, as existing technologies do not effectively support real-time location tracking and identification needs.

Innovation Solution

A method for wireless communication that involves network devices receiving area information messages and transmitting terminal lists to query devices, utilizing existing network infrastructure to map and filter terminal information within defined areas, enabling accurate identification and location reporting of UAVs and other terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing communication systems are used for terminal identification, then general wireless communication is supported, but real-time location tracking and identification of terminals in specific areas cannot be achieved

Engineering Contradiction:
Improvelocation tracking precisionVSAvoidarea query capability
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent introduces a network device as an intermediary between terminal devices and query devices. This network device receives area information from query devices, maintains terminal location information, and returns terminal lists matching the queried areas, thereby enabling area-specific terminal identification without modifying terminal devices themselves

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The network device performs preliminary actions by maintaining and updating terminal location information in advance. Terminal devices report their location information to the network device, which stores this data before any query occurs, enabling rapid real-time querying without requiring terminals to continuously broadcast their positions

Inventive Principle:
Principle #10Preliminary action

2Reliability

If comprehensive terminal information is collected for area querying, then accurate terminal identification is achieved, but network complexity and information management burden increase

Engineering Contradiction:
Improveterminal identification accuracyVSAvoidnetwork device complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts only the necessary location information from comprehensive terminal data. The network device maintains terminal location information specifically for area querying purposes, separating this function from other network functions, thereby reducing the complexity of information management while ensuring accurate terminal identification in queried areas

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The network device implements local quality by maintaining location information with specific focus on area-based querying needs. Rather than managing all possible terminal attributes, the system selectively maintains and processes only the location-relevant data required for area queries, optimizing resource usage and reducing complexity

Inventive Principle:
Principle #3Local quality
