Solution Overview

Problem

Current content distribution in wireless networks relies on host-based protocols like IP, which scales poorly as content distribution becomes dominant, and faces challenges such as inefficient media delivery, session-based protocols, and publisher mobility issues in Content Centric Networking (CCN) implementations.

Innovation Solution

Implementing Information/Content Centric Networking (ICN) paradigms in base stations and wireless devices, allowing ICN bearers to operate parallel to standard Packet Data Network (PDN) bearers, leveraging 3GPP mechanisms for control and mobility management, and integrating CCN-over-LTE to optimize media distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If host-based protocols like IP are used for content distribution, then existing network infrastructure can be utilized, but scalability deteriorates as content distribution becomes dominant

Engineering Contradiction:

Improvecompatibility with existing infrastructureVSAvoidscalability

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the network into two parallel paths: traditional IP-based bearers for control signaling and ICN-based bearers for content distribution. This segmentation allows the system to maintain compatibility with existing IP infrastructure while simultaneously enabling scalable content distribution through ICN protocols, thus resolving the contradiction between infrastructure compatibility and scalability.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If session-based protocols are used, then existing communication frameworks can be leveraged, but efficiency deteriorates for media delivery

Engineering Contradiction:

Improvecompatibility with existing frameworksVSAvoidmedia delivery efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent introduces ICN bearers as an intermediary layer specifically for content distribution, while maintaining the traditional IP bearer for control functions. This intermediary approach allows efficient content-centric media delivery without completely replacing the existing session-based IP framework, thus resolving the contradiction between framework compatibility and delivery efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If Content Centric Networking is implemented, then content delivery efficiency is improved, but publisher mobility issues arise

Engineering Contradiction:

Improvecontent delivery efficiencyVSAvoidpublisher mobility support

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent merges ICN content distribution bearers with traditional IP control bearers in a unified radio access network. The base station maintains both bearer types simultaneously, allowing ICN to provide efficient content delivery while the integrated IP infrastructure continues to handle mobility management and publisher location tracking, thus resolving the contradiction between delivery efficiency and mobility support.

Inventive Principle:

Principle #5Merging (Combining)
