Solution Overview

Problem

Wireless Priority Service (WPS) data messaging in wireless communication networks is vulnerable to attacks that diminish the Quality-of-Service (QoS) for legitimate devices, leading to message discard during network overloads.

Innovation Solution

The implementation of enhanced QoS management through provisioning circuitry that transfers a QoS code to a Subscriber Identity Module (SIM) in User Equipment (UE), allowing messaging circuitry to add a QoS header to network messages, ensuring they are not discarded during overloads, and maintaining priority service for critical personnel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If WPS devices use a special QoS to avoid message discard during network overloads, then message delivery reliability is improved, but the system becomes vulnerable to attacks by malicious devices that can illegitimately obtain WPS QoS

Engineering Contradiction:

Improvemessage delivery reliabilityVSAvoidsecurity vulnerability to QoS abuse

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary authentication mechanism where the network verifies the legitimacy of WPS QoS requests. The provisioning system acts as a mediator that authenticates devices before granting enhanced QoS, preventing malicious devices from illegitimately obtaining priority service while maintaining reliable message delivery for authenticated WPS devices

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the network handles all messages with enhanced QoS processing, then message delivery reliability is improved, but network processing overhead and complexity increase

Engineering Contradiction:

Improvemessage delivery reliabilityVSAvoidnetwork processing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by implementing enhanced QoS processing only for specific priority messages that require it, rather than uniformly processing all messages with enhanced QoS. The system selectively applies priority handling based on message type and sender identity, reducing overall network processing complexity while maintaining high reliability for critical communications

Inventive Principle:

Principle #3Local quality

3Speed

If WPS access class is used to avoid access delays during network overloads, then access speed is improved, but malicious devices can exploit this to gain illegitimate access priority

Engineering Contradiction:

Improveaccess speedVSAvoidillegitimate access by malicious devices

Core Design Contradiction:

SpeedVSObject-affected harmful factors

Solution Approach 1:

The patent implements preliminary authentication actions before granting WPS access class privileges. The provisioning system pre-authenticates devices and verifies their legitimacy before allowing them to use the special access class, ensuring that only authorized devices can exploit the fast access path during network overloads

Inventive Principle:

Principle #10Preliminary action

AI summary

In a wireless communication network, provisioning circuitry transfers a QoS code to a Subscriber Identity Module (SIM) in wireless User Equipment (UE). The UE receives a user message, and in response, retrieves the QoS code from the SIM. The UE wirelessly transfers a network message having the user message and the QoS code to messaging circuitry. In response to the QoS code, the messaging circuitry adds a QoS header to the network message. The messaging circuitry handles the network message with the enhanced QoS responsive to the QoS header. The messaging circuitry generates a new network message having the QoS header and the user message. The messaging circuitry handles the new network message with the enhanced QoS. The messaging circuitry transfers the new network message having the QoS header and the user message for delivery to the destination.
