Solution Overview

Problem

Current communication networks face challenges in optimizing bandwidth consumption, particularly when handling high-bandwidth content like IP-TV or broadcasting, which can lead to system overload and unnecessary storage of non-real-time traffic, preventing full service delivery.

Innovation Solution

Implementing a method to delimit Quality of Service (QoS) to a maximum sustainable level for the delivery interface, optionally buffering traffic for later retrieval, and using transcoding and digital signatures to manage bandwidth and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high bandwidth consuming Content of Communication like IP-TV or broadcasting data is delivered to monitoring function, then monitoring capability is improved, but bandwidth consumption increases and system overload occurs

Engineering Contradiction:

Improvemonitoring capabilityVSAvoidbandwidth consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies parameter changes by transcoding Content of Communication from high bandwidth formats to lower bandwidth formats. The system changes the quality parameters of the media content while maintaining its essential monitoring functionality, thereby reducing bandwidth consumption without completely sacrificing monitoring capability

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent implements local quality by delivering different quality levels of Content of Communication to different destinations. High quality original content is preserved for cases where full monitoring capability is needed, while lower quality transcoded content is delivered for routine monitoring, optimizing bandwidth usage based on specific needs

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If Content of Communication is buffered for later delivery, then delivery flexibility is improved, but storage requirements increase

Engineering Contradiction:

Improvedelivery flexibilityVSAvoidstorage requirements

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent reduces storage requirements by transcoding buffered Content of Communication to lower quality representations before storage. This parameter change allows the system to maintain delivery flexibility while significantly reducing the volume of storage resources needed, as lower quality content occupies less space

Inventive Principle:

Principle #35Parameter changes

3Reliability

If original Quality of Service is maintained for all traffic, then service quality is improved, but bandwidth consumption increases and delivery capacity is reduced

Engineering Contradiction:

Improveservice qualityVSAvoiddelivery capacity

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent applies local quality by providing different Quality of Service levels to different traffic flows based on their specific requirements. Critical traffic receives full quality service, while non-critical traffic is delivered with reduced quality, thereby increasing overall delivery capacity while maintaining service quality where needed

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements partial action by delivering only the necessary portion of full quality service. Instead of maintaining original QoS for all traffic, the system delivers sufficient quality to meet monitoring requirements while reducing bandwidth consumption, applying full quality only when absolutely necessary

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Methods and apparatuses to enhance delivery capacity for traffic in a communication network are disclosed. Traffic is received to a Delivery Function with originally coded Quality of Services (QoS). A specification of requested QoS is received to the Delivery Function. The originally coded QoS is established to be higher than the requested QoS. The received traffic is transcoded into requested QoS. Optionally, the traffic is buffered with originally coded QoS and at request, the buffered traffic is retrieved.
