Header-Based Relay Resource Selection Without Source Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing relay devices fail to determine the appropriate relay resource for communication requests when the transmission source device does not perform signaling, leading to improper resource selection.
Innovation Solution
A relay device with a storage unit, data acquisition unit, and relay resource determination unit that uses a correspondence table to correlate header information with relay resources, allowing it to select the appropriate relay resource based on the communication request class defined by the header information.

Engineering Contradiction Analysis
1Reliability
If the transmission source device does not perform signaling, then the relay device cannot determine the communication request class, but the relay device still needs to select appropriate relay resources for data transmission
Solution Approach 1:
The relay device performs preliminary actions by extracting header information from acquired data and determining the communication request class before actual data transmission. The relay resource determination unit uses this pre-determined class to select appropriate relay resources, ensuring reliable resource selection even without signaling from the transmission source device.
Solution Approach 2:
The header information acts as an intermediary that carries communication request class information between the transmission source device and the relay resource selection process. By extracting and utilizing this intermediate information, the relay device can determine the communication request class without direct signaling from the source device, resolving the information loss problem.
2Measurement precision
If the relay device extracts and processes header information to determine communication request class, then relay resource selection accuracy improves, but device complexity increases
Solution Approach 1:
The relay resource determination unit extracts only the necessary header information from the acquired data to determine the communication request class. By taking out only the essential information needed for resource selection rather than processing entire data packets, the system achieves accurate classification while minimizing processing complexity.
Solution Approach 2:
The relay device applies different processing qualities to different parts of the data: header information receives detailed analysis for communication request class determination, while the main data payload receives standard relay processing. This local quality approach ensures accurate resource selection based on header characteristics without unnecessarily increasing overall device complexity.

AI summary
A relay device includes: a storage unit storing a correspondence table that correlates header information with a relay resource, the relay resource implementing a communication request class defined based on the header information; a data acquisition unit acquiring the data transmitted from the transmission source device as acquired data; a relay resource determination unit determining a relay resource for the acquired data based on header information included in the acquired data and the correspondence table; and a data transmission unit transmitting the acquired data to the destination device using the relay resource determined by the relay resource determination unit.
