Solution Overview

Problem

Wireless communication networks and Content Delivery Networks (CDNs) do not effectively interface with user devices and media servers that have Universal Plug and Play (uPnP) media capability, leading to inefficient media content distribution.

Innovation Solution

A communication system that associates media content identifiers with content network and user identifiers, allowing wireless networks to transfer these identifiers and media content between data and wireless communication networks, enabling efficient distribution to user devices through complex combinations of content IDs, network IDs, and user IDs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If CDNs and eMBMS systems use traditional interface methods with uPnP devices, then device compatibility is maintained, but distribution efficiency and effectiveness deteriorate

Engineering Contradiction:
Improvemedia content distribution efficiencyVSAvoidinterface compatibility with uPnP devices
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent introduces an intermediary entity that acts as a bridge between the CDN/eMBMS system and uPnP devices. This intermediary translates and maps identifiers between the CDN content identifier space and the uPnP device identifier space, enabling efficient content distribution while maintaining compatibility with existing uPnP devices and media servers without requiring direct complex interfaces.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If complex ID combinations are used to enhance security and distribution control, then distribution control and security are improved, but system complexity increases

Engineering Contradiction:
Improvedistribution securityVSAvoidsystem architecture complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the identifier system into distinct components: CDN content identifiers, network identifiers, user identifiers, and device identifiers. Each segment serves a specific function in the distribution chain. The intermediary entity processes these segmented identifiers separately through systematic mapping, which maintains security and control while avoiding the need for complex integrated identifier systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transforms the identifier parameters between different system domains. The intermediary entity performs parameter mapping and transformation between CDN's content identifier space and uPnP's device identifier space, maintaining security requirements while simplifying the interface through systematic parameter conversion rather than complex multi-parameter combinations.

Inventive Principle:
Principle #35Parameter changes
