Solution Overview

Problem

Current wireless technologies, such as LTE and UMTS, face challenges in managing access priority for low access priority devices during network congestion, leading to potential abuse and network overload when dual access priority capabilities are not supported by all networks.

Innovation Solution

Devices configured for low access priority can dynamically adjust their priority settings by transmitting a registration request indicating support for multiple access priorities, allowing them to request service connections at higher priority levels only if permitted by the network, based on congestion levels and network support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If low access priority devices are granted dual access priority capability, then they can send high priority information (e.g., tamper alerts, low resource warnings) with normal access priority, but they may abuse this capability and cause network overload during congestion

Engineering Contradiction:
Improveaccess priority flexibilityVSAvoidnetwork congestion and abuse
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The network performs preliminary configuration of dual access priority capability during device registration, before the device actually needs to access the network. The network stores the device's identity and associated higher access priority in advance, so when the device later requests service, the network can quickly verify and grant appropriate priority without allowing abuse. This preliminary setup enables legitimate high-priority access while maintaining network control to prevent overload.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If low access priority devices are blocked during network congestion, then network resources are protected for high priority devices, but legitimate high priority communications (e.g., emergency alerts, critical service requests) cannot be delivered

Engineering Contradiction:
Improvenetwork resource protectionVSAvoidservice delivery capability
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically adjusts device access priority based on network conditions and device-specific configurations. During registration, the network identifies devices with legitimate needs for higher priority (such as emergency alert receivers or critical service devices) and configures them with dual access priority capability. When congestion occurs, these pre-configured devices can dynamically switch to higher priority access, while other low-priority devices remain blocked. This dynamic approach ensures critical communications get through during congestion while still protecting overall network resources.

Inventive Principle:
Principle #15Dynamics

3Productivity

If all devices are configured for normal access priority, then service delivery is improved, but network congestion increases and resource protection for high priority devices is reduced

Engineering Contradiction:
Improveservice delivery efficiencyVSAvoidnetwork load
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

Instead of uniformly configuring all devices with normal access priority, the network applies local quality by configuring dual access priority capability selectively on a per-device basis during registration. The network evaluates each device's identity and determines whether it has legitimate needs for higher priority access (such as emergency alert capabilities or critical service requirements). Only these specific devices receive the dual priority configuration, while other devices remain with standard low-priority settings. This localized approach improves service delivery for critical devices without increasing overall network load from unnecessary high-priority requests.

Inventive Principle:
Principle #3Local quality

AI summary

In one embodiment, the method for registering to a wireless network (100) includes transmitting a registration request from a device (120) designated as having a low access priority. The registration request includes a value indicating that the device supports multiple access priorities. The multiple access priorities include the low access priority and at least one higher access priority. The method further includes requesting access when connecting to the wireless network based on a response to the registration request.
