Third-Party Assisted P2P Communication via Network Coding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as LTE, lack efficient methods for implementing network coding in third-party assisted peer-to-peer (P2P) communications, which are essential for direct connections between mobile entities without relying on network infrastructure.
Innovation Solution
A method and apparatus for third-party assisted P2P communication, where a third-party entity, like an evolved NodeB or a mobile entity, receives and codes information from two mobile entities and transmits the coded information back to them, along with control signals for decoding, enabling direct communication between peers with the assistance of a third party.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If direct wireless connection between mobile entities is implemented, then communication efficiency is improved, but network infrastructure support is reduced
Solution Approach 1:
The patent introduces a base station as an intermediary entity that facilitates P2P communication between mobile entities. The base station receives messages from both mobile entities, performs network coding to generate coded messages, and transmits these coded messages back to the mobile entities. This intermediary approach enables direct P2P communication while maintaining network infrastructure support and control.
2Productivity
If network coding is implemented in P2P communication, then data transmission efficiency is improved, but system complexity is increased
Solution Approach 1:
The patent extracts the network coding function from the mobile entities and places it in the base station. The base station performs the complex network coding operations (receiving messages, encoding, and generating coded messages) while the mobile entities only need to send and receive messages. This extraction reduces the complexity burden on mobile devices while maintaining the efficiency benefits of network coding.
3Reliability
If third-party assisted P2P communication is implemented, then communication reliability is improved, but infrastructure dependency is increased
Solution Approach 1:
The base station performs multiple functions: it acts as a relay for P2P communication, performs network coding to improve efficiency, and maintains control over the communication process. This multi-functionality allows the system to achieve reliable P2P communication while using existing infrastructure capabilities, rather than requiring separate dedicated systems.

AI summary
Techniques are provided for third-party assisted peer-to-peer (P2P) communication. For example, there is provided a method, operable by a network entity, that may involve receiving first information from a first mobile entity, the first information comprising a first message for a second mobile entity. The method may involve receiving second information from the second mobile entity, the second information comprising a second message for the first mobile entity. The method may further involve coding third information based at least in part on the first information and the second information, and sending the third information to the first and second mobile entities. The method may also involve transmitting a control signal that includes processing information for decoding the coded third information to extract the first message or the second message.
