Solution Overview

Problem

In certain wireless communications networks, network devices are not aware of when authentication is completed by another device, leading to inefficient data transmission and time wastage.

Innovation Solution

Methods and apparatuses for communicating and storing aerial system security information involve transmitting and receiving messages between network functions, including aerial vehicle identifiers, subscription identifiers, and security policy information, with the ability to store authentication results and security requirement information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If network devices perform authentication independently without sharing authentication status, then each device can authenticate autonomously, but data transmission efficiency decreases and time is wasted due to redundant authentication processes

Engineering Contradiction:

Improvedata transmission efficiencyVSAvoidauthentication time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements a feedback mechanism where the access and mobility management function receives authentication status information from the uncrewed aerial system network function and uses this feedback to determine whether to perform authentication for data transmission. This feedback loop eliminates redundant authentication by allowing network devices to awareness of previous authentication results, thereby improving data transmission efficiency and reducing time loss.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent performs preliminary authentication action by having the access and mobility management function check authentication status before initiating data transmission. The authentication status is queried in advance from the uncrewed aerial system network function, and only if authentication is needed is the actual authentication process initiated. This preliminary check prevents time-wasting redundant authentication and improves overall productivity.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If network devices store and share authentication status information, then authentication efficiency improves and redundant processes are reduced, but system complexity increases due to additional message transmission and storage requirements

Engineering Contradiction:

Improveauthentication efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent applies universality by having the access and mobility management function serve multiple purposes: it manages both access and mobility, stores authentication status information, and uses this information to control data transmission. The uncrewed aerial system network function also serves multiple functions by providing both authentication services and storing authentication status. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in system complexity while maintaining improved authentication efficiency.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent uses the access and mobility management function as an intermediary that mediates between the uncrewed aerial system network function and the data transmission process. This intermediary stores and manages authentication status information, simplifying the overall system architecture by centralizing the authentication status management function rather than requiring each network device to independently manage and share authentication information.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If network devices transmit and store security information, then security management improves and authentication results are available, but energy consumption increases due to additional communication and processing

Engineering Contradiction:

Improvesecurity managementVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by having the access and mobility management function transmit and store only the necessary authentication status information (such as authentication result indicators) rather than all possible security information. This selective information handling maintains adequate security management and authentication result availability while minimizing the energy consumption associated with transmitting and processing excessive data.

Inventive Principle:

Principle #16Partial or excessive action
