Mobile Terminal Content Sharing via Peer-to-Peer Index Lookup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for mobile data content services leads to a bandwidth bottleneck, degrading the quality of data content services and user experience due to limited wireless spectrum resources.
Innovation Solution
A method and apparatus for content sharing among mobile terminals, where a requesting mobile terminal receives an index of access content, looks up a shareable content index table, and sends identification information to the requesting mobile terminal to obtain the content from another mobile terminal via wireless communication, thereby saving spectrum resources and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile users access content services through base stations via Air Interface, then users can obtain data content services, but wireless spectrum resources are limited and bandwidth bottleneck emerges
Solution Approach 1:
The patent merges the content delivery function from traditional network-based delivery to peer-to-peer delivery among mobile terminals. Mobile terminals that have cached content share it directly with other terminals via wireless communication, combining the roles of content consumer and content provider in a single system, thereby reducing the burden on base stations and expanding overall service capacity without requiring additional spectrum resources.
Solution Approach 2:
The patent implements a content copying mechanism where mobile terminals cache content locally and create copies for sharing. Instead of repeatedly transmitting content through the Air Interface from base stations, terminals store local copies and share these copies peer-to-peer, significantly reducing wireless spectrum consumption while maintaining service availability.
2Productivity
If base stations transmit content to mobile terminals through Air Interface, then content delivery is achieved, but quality of data content services is degraded due to bandwidth bottleneck
Solution Approach 1:
The patent introduces mobile terminals as intermediary nodes in the content delivery chain. Instead of direct base station-to-terminal transmission for all content requests, terminals that have cached content act as intermediaries, relaying content to requesting terminals through direct wireless communication. This intermediary mechanism bypasses the congested Air Interface bottleneck and improves service quality.
Solution Approach 2:
The patent segments the content delivery function into multiple independent paths: traditional base station delivery and peer-to-peer terminal delivery. By dividing the monolithic content delivery system into segmented pathways, the patent enables parallel content distribution, reducing congestion on any single path and improving overall service reliability and quality.
3Productivity
If wireless spectrum resources are increased to satisfy user requirements, then mobile data content service capacity can be improved, but spectrum resources are limited and cannot be expanded
Solution Approach 1:
The patent implements a self-service mechanism where mobile terminals independently provide content sharing services to each other without requiring additional network infrastructure or spectrum resources. Terminals use their own cached content and wireless communication capabilities to serve other terminals, enabling the system to self-expand capacity without external resource investment.
Solution Approach 2:
The patent transitions content delivery from a single dimension (base station to terminal via Air Interface) to multiple dimensions by adding peer-to-peer terminal-to-terminal communication. This dimensional expansion creates additional content delivery pathways that do not consume additional spectrum resources, effectively increasing service capacity within the same resource constraints.

AI summary
A method for realizing content sharing among mobile terminals comprises: receiving an index of access content sent by a requesting mobile terminal; looking up a shareable content index table for the index of the access content; and sending identification information of a mobile terminal having the index of the access content to the requesting mobile terminal if the index of the access content is found, so that the requesting mobile terminal obtains the requested access content from the mobile terminal having the index of the access content via wireless communication.
