Solution Overview

Problem

Existing mobile data networks face congestion issues due to uneven traffic distribution across cells, which can lead to connectivity problems and require costly hardware upgrades to address, especially with the increasing demand from technologies like IoT and connected vehicles.

Innovation Solution

A system that determines network state by measuring transmission resources and user utilization across cells, using a server to adjust traffic flow and device behavior through traffic signals, speed limits, and messages to mobile devices to optimize traffic distribution across cells without hardware upgrades.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If hardware upgrades are implemented to support increased data traffic demand, then network capacity and bandwidth are improved, but infrastructure cost and deployment time increase

Engineering Contradiction:
Improvenetwork capacityVSAvoidinfrastructure cost
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system changes the parameter of traffic distribution by dynamically adjusting user behavior parameters (location, time, media) rather than changing physical infrastructure parameters. This allows the network to adapt to increased demand through software-based traffic management instead of hardware upgrades.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system implements feedback loops where network traffic data is continuously monitored and used to generate real-time recommendations for users. This feedback mechanism enables the network to self-regulate traffic distribution based on current load conditions, eliminating the need for proactive infrastructure expansion.

Inventive Principle:
Principle #23Feedback

2Device complexity

If traffic is concentrated on fewer cells, then network infrastructure complexity is reduced, but connectivity reliability deteriorates due to overload on heavy-loaded cells

Engineering Contradiction:
Improvenetwork infrastructureVSAvoidconnectivity availability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system segments the network traffic load by distributing users across multiple cells based on real-time conditions. Instead of concentrating traffic on fewer cells, the system divides the user base and directs different segments to different cells, preventing any single cell from becoming overloaded and maintaining overall network reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system makes traffic distribution dynamic rather than static. Users are continuously redirected based on changing network conditions, allowing the system to adapt to varying loads across cells. This dynamic approach ensures that no single cell becomes a permanent bottleneck while maintaining simplified infrastructure.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If users are allowed to freely access any cell, then user convenience is improved, but traffic distribution becomes uneven causing congestion on popular cells

Engineering Contradiction:
Improveuser access freedomVSAvoidtraffic distribution efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system introduces an intermediary layer (the traffic management system) between users and cells. Instead of users directly choosing cells based on personal preference, the intermediary system mediates access by providing recommendations that balance user convenience with network efficiency. Users still have freedom to choose but are guided toward less congested options.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces the mechanical approach of physical infrastructure expansion with an information-based system. Instead of adding more cells or capacity through hardware, the system uses information recommendations to guide users toward underutilized cells, achieving balanced traffic distribution through software rather than mechanical infrastructure changes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A traffic adjustment or a traffic command, for example, is based on data congestion on a cellular network. Position data is received from a mobile device. A portion of a cellular network that corresponds to the position data is selected. The portion of the cellular network may be the geographic area covered by a cell. The network state of the portion of the cellular network is identified. A traffic device is also identified. The traffic device may be a traffic light or a variable speed sign. The traffic adjustment or traffic command for the traffic device is calculated based on the network state.
