Managed Peer-to-Peer Content Sharing in Cellular Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communications systems face challenges in efficiently delivering bandwidth-intensive content due to latency issues and high operational costs associated with deploying cache servers to reduce latency and congestion in wireless networks.
Innovation Solution
Implementing a peer-to-peer (P2P) content data sharing system where client and server peer nodes share bandwidth and storage, reducing the reliance on centralized servers by redirecting content requests through a P2P application server that manages a list of capable peer nodes for content distribution, thereby optimizing network operations and minimizing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If cache servers are deployed to reduce content delivery latency and network congestion, then content delivery speed is improved, but operational costs and deployment complexity increase
Solution Approach 1:
The patent enables peer nodes to autonomously share content data with each other without requiring centralized cache server infrastructure. Each peer node acts as both a consumer and potential provider of content, self-organizing into a distributed caching network that eliminates the need for operator-deployed cache servers while reducing content delivery latency
Solution Approach 2:
The P2P application server acts as a lightweight intermediary that maintains a list of peer nodes capable of providing content data. Instead of deploying heavy cache server infrastructure, the system uses this minimal intermediary to route content requests to appropriate peer nodes, achieving cache-like functionality without the operational overhead
2Productivity
If centralized cache servers are used to reduce network congestion, then data transmission efficiency is improved, but Internet transit costs increase
Solution Approach 1:
The patent segments the centralized cache server functionality into distributed peer nodes throughout the network. Instead of all content flowing through centralized cache servers (incurring transit costs), content is segmented and stored across multiple peer nodes, allowing local delivery without Internet transit and reducing overall network congestion
3Quantity of substance
If peer-to-peer content sharing is implemented to reduce centralized server demands, then storage and bandwidth costs are reduced, but network management complexity increases
Solution Approach 1:
The P2P application server serves as a management intermediary that maintains the peer node capability list and routes content requests. This minimal intermediary handles the coordination complexity, allowing peer nodes to independently provide content without requiring complex peer-to-peer discovery and management protocols, thus reducing centralized server storage demands while keeping management simple

AI summary
A method, system and apparatus are provided for performing peer-to-peer (P2P) data sharing operations between user equipment (UE) devices in a wireless-enabled communications environment. A first client node comprises content data and operates in a server peer mode to provide content data. A second client node submits a request to a P2P application server (P2P AS) for the content data. In response, the P2P AS provides the address of the first client node to the second client node. The second client node then uses the provided address to submit a request to the first client node to provide the content data. The first client node accepts the request and then provides the content data to the second client node.
