Media Content Identifier Distribution via Intermediary Mapping
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
2Reliability
If complex ID combinations are used to enhance security and distribution control, then distribution control and security are improved, but system complexity increases
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.
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.

AI summary
A data network (120) receives data associating media content identifiers with a content network identifier and a content user identifier. A wireless network (130) receives a registration indicating the content network identifier and the content user identifier and transfers the content network identifier and the content user identifier to the data network (120). The data network (120) identifies the media content identifiers associated with the content network identifier and the content user identifier and transfers the media content identifiers to the wireless communication network (130). The wireless network (130) receives a media request from a wireless communication device (140) indicating the content network identifier and the content user identifier. The wireless network (130) transfers the media content identifiers associated with content network identifier and the content user identifier to the wireless communication device (140).
