Solution Overview

Problem

The increasing number of communication devices in cellular networks leads to network complexity, higher operational and financial costs, and congestion issues, especially during high-demand events, while broadcast networks offer a more efficient and less complex infrastructure for data transmission.

Innovation Solution

A load data transformer is introduced to offload data from cellular networks to broadcast networks by transforming the data based on the available radio access network resources, including quality adjustment, storage, and scheduling to optimize transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If cellular networks dimension the network for average load, then network complexity and costs are controlled, but congestion and overload situations occur during high-demand events

Engineering Contradiction:
Improvenetwork complexityVSAvoidnetwork reliability during high-demand events
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent introduces a broadcast network as an intermediary system to handle high-demand data transmission. When cellular networks experience congestion during high-demand events, the system switches data transmission to the broadcast network, which has different resource characteristics and can handle large-scale data distribution without the same congestion issues. This mediator approach allows the cellular network to maintain its cost-effective average load dimensioning while relying on the broadcast network for peak demand scenarios.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If more transceivers with higher capabilities are provided to serve increased number of devices, then network capacity increases, but technical complexity and operational costs increase

Engineering Contradiction:
Improvenetwork capacityVSAvoidtechnical complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges two different network infrastructures - cellular networks and broadcast networks - into a hybrid system. The cellular network handles unicast communication for individual device services, while the broadcast network handles multicast/broadcast data transmission for high-demand events. This combination allows the system to achieve high network capacity for serving increased numbers of devices without requiring each cellular transceiver to have higher capabilities, thereby avoiding the associated technical complexity and operational cost increases.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If cellular networks use unicast communication model to provide services, then individual device services are ensured, but network resources are overconsumed during high-demand events

Engineering Contradiction:
Improveindividual device service qualityVSAvoidnetwork resource consumption
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The patent implements a dynamic communication model that can switch between unicast and broadcast/multicast modes based on demand characteristics. For individual device services, the system uses unicast communication to ensure quality of service. During high-demand events where multiple users consume the same content, the system dynamically switches to broadcast network transmission, which efficiently delivers the same data to multiple users simultaneously. This dynamic approach maintains ease of operation for individual services while dramatically reducing network resource consumption during high-demand events.

Inventive Principle:
Principle #15Dynamics
