Relay Device Communication State Reporting Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to ensure timely reporting of communication states between a base station and a terminal, leading to potential degradation of quality of experience when communication quality deteriorates, as they rely on TCP packets passing through the base station, which may not always be present.
Innovation Solution
An information reporting device that transfers communication state information to a communication device via packets transmitted by the terminal, including a communication state giving unit, a data transfer unit, and a compensation unit to implement report compensation processing when packets are not received, ensuring continuous reporting even when communication quality is poor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If communication state information is reported by embedding it in TCP packets that pass through the base station, then the reporting method is simple and does not require terminal changes, but the reporting may be delayed or lost when TCP packets are not present due to poor communication quality
Solution Approach 1:
The patent introduces a relay device as an intermediary between the terminal and server. The relay device receives communication state information from the terminal via uplink packets, stores it temporarily, and forwards it to the server via downlink packets. This mediator ensures that reporting reliability is maintained even when direct TCP packet paths are unavailable due to poor communication quality.
Solution Approach 2:
The terminal performs preliminary action by embedding communication state information in uplink packets before the actual data transmission. The relay device then uses this pre-prepared information to generate compensation reports when needed, ensuring that reporting can occur even without real-time TCP packet availability.
2Reliability
If communication state information is reported continuously, then the quality of experience can be maintained, but the volume of feedback information increases
Solution Approach 1:
Instead of continuously reporting all communication state information, the patent implements compensation reporting that only occurs when necessary (when TCP packets are absent or communication quality deteriorates). The relay device determines whether compensation reporting is needed based on packet arrival status, thus reducing overall information volume while maintaining QoE when it matters most.
Solution Approach 2:
The system implements a feedback mechanism where the relay device monitors packet arrival status and dynamically adjusts reporting behavior. When packets arrive normally, reporting is minimal; when packets are missing or communication quality drops, the relay device generates compensation reports to ensure the server receives updated communication state information.
3Reliability
If the server performs communication control based on reported communication throughput, then the quality of experience improves, but the system becomes more complex
Solution Approach 1:
The patent extracts the communication control function from the terminal and relocates it to the server. The terminal only needs to report communication state information, while the server performs the complex communication control operations such as adjusting bit rates and selecting coding schemes. This separation simplifies the terminal while enabling sophisticated control at the server level.

AI summary
An information notification device which transfers to a communication device a packet transmitted by a terminal to a relay device. The information notification device is provided with: a communication condition providing unit which provides the packet transmitted by the terminal with communication condition information concerning a communication condition between the terminal and the relay device; a data transmission unit which transmits the packet provided with the communication condition information to the communication device; and a supplementation unit which, in the absence of arrival of the packet from the terminal, implements a notification supplementation process for notifying the communication device of the communication condition information.
