Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current D2D communication technologies face challenges in ensuring data transmission security and efficiency due to trust and incentive issues, particularly in selecting reliable nodes for data relay services within the network.
Innovation Solution
A data transmission method that determines whether to use D2D communication based on service requests, selects nodes based on physical and business domain principles, including credit and incentive criteria, to establish a secure and efficient network structure for data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If D2D communication is adopted for data transmission, then spectrum efficiency and system throughput are improved, but data transmission security and trust reliability deteriorate due to trust and incentive issues
Solution Approach 1:
The patent introduces a network side intermediary that mediates between D2D communication nodes. The network side determines whether to adopt D2D communication, selects bearer network nodes, and establishes network structures based on physical domain and business model domain principles. This intermediary mechanism ensures data transmission security while maintaining the efficiency benefits of D2D communication.
2Use of energy by moving object
If D2D communication is adopted for data transmission, then energy consumption of user devices is reduced, but system complexity increases due to node selection and network structure determination
Solution Approach 1:
The patent segments the D2D communication system into distinct domains: physical domain (for signal quality and distance-based selection) and business model domain (for credit and incentive-based selection). This segmentation allows complex node selection to be divided into manageable components, reducing overall system complexity while enabling energy-efficient D2D communication.
3Productivity
If nodes are selected based on physical domain principles only, then data transmission efficiency is improved, but transmission reliability deteriorates due to lack of security and credit verification
Solution Approach 1:
The patent merges physical domain selection criteria (distance, signal quality) with business model domain criteria (credit relationships, incentive principles) to select bearer network nodes. This combination ensures that nodes selected for data transmission are both physically suitable and trustworthy, thereby improving transmission reliability without sacrificing efficiency.
4Reliability
If credit principle is applied on both network side and terminal side, then data transmission security is improved, but device complexity increases due to dual-side credit management
Solution Approach 1:
The patent applies credit management with different levels of quality at different locations: the network side implements comprehensive credit management including access control based on subscription data and historical data, while terminal side implementation is more localized. This local quality approach enhances security without uniformly increasing complexity across all devices.
Data Source
AI summary
The present disclosure provides a data transmission method, including: upon receipt of a service request, it is determined whether said service request is a data sharing request; if the determined result is that said service request is a data sharing request, then the data source node and data-receiving destination node corresponding to said data sharing request are determined; according to the distance principle and/or signal quality principle and the credit principle and/or incentive principle, a bearer network node is selected corresponding to said data source node and said data-receiving destination node; according to said bearer network node, data source node, and data-receiving destination node, the data sharing network structure is determined. The technical solution of the present disclosure resolves the trust and incentive problem in terminal direct-connection communication networks, increasing security in the sharing of data.
