Communication Terminal Signal Quality Balancing via CPU Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, particularly during two-way communication events like video calls, participants often experience uneven quality of service due to unbalanced processing resource utilization, where one terminal may receive a high-quality signal while the other receives a low-quality signal, leading to potential call termination.
Innovation Solution
A method where a second terminal estimates its own processing resources for receiving and transmitting signals and adjusts the signal characteristics of the first signal it receives, determining a balance that considers both receiving and transmitting resources, and sends this decision back to the first terminal to adjust its transmission accordingly, ensuring balanced quality of service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a receiving terminal adjusts the data transmission rate based on its available CPU resources, then the processing load on the receiving terminal is optimized, but the quality of service experienced by the other participant deteriorates due to unbalanced signal quality
Solution Approach 1:
The patent implements a feedback mechanism where each terminal reports its available CPU resources to the other terminal. The transmitting terminal then uses this feedback information to adjust the data transmission rate dynamically, ensuring that the receiving terminal can process the incoming data without being overwhelmed, while maintaining acceptable signal quality for both participants.
Solution Approach 2:
The patent makes the data transmission rate dynamic rather than fixed. The transmitting terminal continuously monitors the receiving terminal's CPU resource availability and adjusts the transmission rate in real-time based on these changing conditions. This dynamic adjustment allows the system to adapt to varying processing capabilities and maintain balanced quality of service throughout the communication session.
2Manufacturing precision
If one terminal receives a high quality signal, then the processing resource requirement increases, but the other terminal may receive a low quality signal due to unbalanced resource allocation
Solution Approach 1:
The patent acknowledges and exploits the asymmetry in terminal capabilities by allowing each terminal to have different signal quality requirements and processing capabilities. Instead of forcing symmetric treatment, the system enables each terminal to negotiate and operate at quality levels appropriate to its specific hardware resources, while the transmitting terminal adapts to ensure the receiving terminal can handle the incoming signal quality.
3Speed
If the transmitting terminal increases the data transmission rate, then the information delivery speed improves, but the receiving terminal's processing resources become insufficient
Solution Approach 1:
The patent changes the transmission parameters (data rate, packet size, encoding complexity) based on the receiving terminal's reported CPU resource availability. When the receiving terminal has sufficient resources, the transmitting terminal increases the data transmission rate and uses higher quality encoding. When resources are constrained, the transmitting terminal reduces the data rate and uses more efficient compression, ensuring reliable processing at all times.

AI summary
A method, terminal and program, the method comprising: at a second terminal, receiving a first signal transmitted from a first terminal via a communication network; transmitting a second signal from the second terminal to the first terminal; outputting the first signal from an output device associated with the second terminal; determining a balance between a characteristic of the first signal and a characteristic of the second signal, wherein the characteristics affect a processing resource required to process the first and second signals, the determined balance comprising a decision concerning the characteristic of the first signal; and sending the decision to the first terminal so as to advise the first terminal to adjust the characteristic of the first signal as transmitted from the first terminal.
