Communication Device Relay Period Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices face delays and instability in data transmission due to the constant relay intervals of relay devices, which can disrupt videoconferencing by causing time delays and irregular packet reception, affecting the smooth progress of videoconferences.
Innovation Solution
A communication device measures the relay period of relay devices and adjusts its transmission period accordingly, synchronizing with the relay period to ensure stable and consistent data transfer, reducing packet communication delay and stabilizing reception intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the communication device reduces the data transmission period to improve transmission efficiency, then the data transmission speed increases, but the relay device cannot relay data at consistent intervals causing communication delays
Solution Approach 1:
The communication device dynamically adjusts its data transmission period based on the measured relay period of the relay device. The transmission period is set to be equal to or a multiple of the relay period, allowing the system to adapt to the relay device's constraints while maintaining efficient data transmission. This dynamic adjustment resolves the contradiction by making the transmission period flexible rather than fixed.
Solution Approach 2:
The communication device measures the relay period by transmitting measurement data and receiving result data back from the relay device. This feedback mechanism allows the communication device to accurately determine the relay period and adjust its transmission period accordingly, ensuring that data transmission is synchronized with the relay device's capabilities and maintaining communication stability.
2Device complexity
If the relay device uses constant relay intervals to simplify data transfer, then the relay operation is simple, but the communication between devices becomes delayed due to fixed timing
Solution Approach 1:
The communication device performs preliminary measurement of the relay period by transmitting measurement data to the relay device and receiving result data. This preliminary action allows the communication device to determine the optimal transmission period before actual data communication begins, enabling it to synchronize transmission with the relay device's constant intervals and reduce communication delays.
3Productivity
If the communication device transmits data at frequent intervals to improve real-time communication, then the data transmission frequency increases, but packet loss and communication delays increase due to relay device constraints
Solution Approach 1:
The communication device changes the transmission period parameter to match or be a multiple of the relay period. By adjusting this temporal parameter, the system ensures that data packets are transmitted at intervals that the relay device can reliably forward, preventing packet loss and maintaining reception stability while still achieving frequent updates through proper parameter synchronization.

AI summary
Determining and configuration a transmission period for a communication device may include transmitting measurement data to measure a relay period of a relay device in the network, where the relay period corresponds to an interval of relaying data to another communication device configured to connectable to network. Additionally, the communication device may receive result data indicative of the relay period of the relay device in response to the measurement data from the other communication device, determine the transmission period at which the communication device transmits data to the other communication device based on the relay period, and transmit data to the other communication device via the relay device based on the determined transmission period.
