Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to reliably acquire the contribution value of a relay node in a non-trusted network environment, as the contribution information from such nodes may be unreliable due to the risk of deception.
Innovation Solution
A method and device that acquire and verify charging information from both trusted and non-trusted nodes, ensuring consistency to calculate the contribution value of the relay node, using charging information such as session duration and network traffic, and converting formats if necessary, to ensure accurate and reliable contribution assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If contribution information is acquired separately from relay nodes in a non-trusted network environment, then the relay mechanism can be widely adopted for traffic relaying, but the contribution information may be unreliable due to the risk of deception by nodes without actual contribution
Solution Approach 1:
The patent introduces a tracker server as an intermediary that collects and verifies contribution information from multiple sources (relay nodes, trusted nodes, and charging information). The tracker server acts as a mediator that cross-checks data from different participants in the communication session, ensuring that the final contribution assessment is reliable even when individual nodes cannot be fully trusted.
Solution Approach 2:
The patent combines multiple sources of charging information (from relay nodes, trusted nodes, and the tracker server) to verify contribution values. By merging data from these different sources and cross-checking for consistency, the system achieves reliable contribution assessment without requiring any single source to be completely trusted.
2Productivity
If charging information from relay nodes is used to calculate contribution value, then the contribution assessment can be obtained, but deception by relay nodes may lead to inaccurate contribution values
Solution Approach 1:
The patent implements a feedback mechanism where the tracker server collects charging information from multiple sources, verifies consistency, and uses this feedback to accurately determine contribution values. The system continuously monitors and cross-checks data from relay nodes, trusted nodes, and charging information to ensure accurate measurement of actual contributions.
Solution Approach 2:
The patent performs preliminary verification of charging information consistency before final contribution calculation. The tracker server pre-collects and validates charging information from multiple sources, ensuring that only consistent and verified data is used in the final contribution assessment, thereby preventing deception from affecting the results.
3Reliability
If multiple sources of charging information are verified for consistency, then reliable contribution value can be acquired, but the system complexity increases
Solution Approach 1:
The patent makes the tracker server a multi-functional component that performs multiple roles: collecting charging information from various sources, verifying consistency, calculating contribution values, and managing relay node scheduling. By consolidating these functions in a single universal component, the system achieves reliable contribution assessment without proportionally increasing overall system complexity.

AI summary
A method and an apparatus for acquiring a contribution value of a transfer node are disclosed. The method includes: acquiring charging information of a trust node which is in a trust network circumstance and joining in a session, and acquiring charging information of the transfer node which is in a distrust network circumstance and joining in the session; auditing the consistency of charging information between the transfer node and the trust node; computing the contribution value of the transfer node according to the auditing result and the charging information of the transfer node. The invention can effectively guarantee acquiring the contribution value of the transfer node truly and unfailingly in a distrust circumstance of network circumstance, and subsequently providing basis for rewarding the node which has contributed for transferring.
