Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current cellular communication systems face bottlenecks due to limited radio frequency spectrum, as existing technologies often restrict transmission rates based on subscriber or content types, leading to inefficient utilization of available spectrum.

Innovation Solution

Implementing a method where content is transmitted at the highest throughput rate by the telecommunication network, with user equipment (UE) controlling playback rates based on content type, service, or subscriber type, and pausing transmission when the buffer is full, allowing for maximum spectrum utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If transmission rate is restricted based on subscriber or content types, then network control and service differentiation are improved, but spectrum utilization efficiency deteriorates

Engineering Contradiction:

Improveservice differentiationVSAvoidspectrum utilization efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent inverts the traditional control approach by having the network transmit at maximum rate and the UE control playback rate instead of network controlling transmission rate. This resolves the contradiction by maintaining service differentiation through UE-side playback control while achieving maximum spectrum utilization through network-side maximum rate transmission.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The UE autonomously determines its own playback rate based on buffer status, content type, and service requirements, eliminating the need for network to restrict transmission rates. This self-service mechanism resolves the contradiction by enabling UEs to self-regulate playback while network maintains maximum throughput.

Inventive Principle:

Principle #25Self-service

2Productivity

If content is transmitted at highest throughput rate, then spectrum utilization is improved, but data overload at UE deteriorates

Engineering Contradiction:

Improvespectrum utilizationVSAvoiddata overload prevention

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The UE continuously monitors buffer status and provides feedback by controlling playback rate, creating a closed-loop system that prevents data overload while maintaining maximum transmission rate. This feedback mechanism resolves the contradiction by dynamically adjusting playback to match transmission capacity.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The playback rate is made dynamic and adjustable based on real-time buffer status, content type, and service requirements rather than being fixed. This dynamic control resolves the contradiction by enabling the system to adapt playback rate to prevent overload while maintaining maximum spectrum utilization.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If transmission rate is limited to match playback rate, then UE buffer management is simplified, but network throughput deteriorates

Engineering Contradiction:

Improvebuffer management complexityVSAvoidnetwork throughput

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The buffer acts as an intermediary between high-rate transmission and controlled playback, decoupling transmission rate from playback rate. This intermediary mechanism resolves the contradiction by allowing maximum transmission rate while maintaining manageable buffer levels through UE-controlled playback.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A user equipment described herein receives content delivered by a telecommunication network at a first rate. The first rate is a highest rate possible for the telecommunication network. The user equipment then renders the content at a second rate that is lower than the first rate.
