Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing session establishment methods in wireless communication do not ensure the privacy of traffic data during relay sessions.
Innovation Solution
A relay session establishing method that uses a relay service code (RSC) to characterize traffic attributes, enabling remote and relay devices to discover and establish sessions based on supported or authorized RSCs, ensuring privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional relay session establishment methods are used, then session setup is simple, but traffic data privacy is not ensured
Solution Approach 1:
The patent segments the session establishment process into distinct phases: relay service code generation based on traffic description, relay device discovery using the code, and session establishment. This segmentation allows privacy protection to be integrated at specific points without overwhelming complexity throughout the entire system.
Solution Approach 2:
The relay service code acts as an intermediary element that mediates between the remote device and relay devices. It carries traffic attribute information in a controlled manner, enabling privacy-preserving discovery and selection of relay devices without exposing full traffic details to unnecessary entities.
2Reliability
If relay service code is introduced to ensure privacy, then traffic attribute privacy is protected, but device complexity increases
Solution Approach 1:
The patent changes the parameter space by introducing relay service codes as a new dimension for identifying and selecting relay devices. Instead of using complex authentication mechanisms or full traffic inspection, the system transforms the selection criteria into a simplified code-based parameter that balances privacy and implementation complexity.
3Adaptability or versatility
If comprehensive relay device discovery is performed, then suitable relay devices can be found, but privacy of traffic data may be exposed
Solution Approach 1:
The patent extracts only the essential privacy-relevant information (traffic attributes) into the relay service code, separating this from the full traffic data. This allows relay devices to be discovered and selected based on compatibility with the code without exposing the complete traffic content to potential eavesdroppers or unauthorized entities.

AI summary
The present application provides a relay session establishing method and apparatus, a device, and a storage medium. This solution provides a method for discovering a relay device by means of a relay service code and establishing a relay session. A remote device determines, according to description information of traffic, a relay service code that is used for indicating a traffic attribute of the traffic, and discovers an appropriate relay device according to the relay service code, and then establishes a relay session with the relay device, so as to transmit data of the traffic. In this solution, the privacy of traffic attribute can be ensured during the process of discovering the relay device.
