Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the relay terminal device reports congestion information to the network device, then the network device can perform congestion control to improve data transmission efficiency and reliability, but the signaling overhead increases due to additional information transmission
Solution Approach 1:
The patent extracts only the essential congestion control information (buffer status, transmission delay, packet loss rate) from the relay terminal device's operational data and transmits only these extracted parameters to the network device. This selective extraction approach enables effective congestion control while minimizing unnecessary signaling overhead compared to transmitting complete operational status data.
Solution Approach 2:
The patent implements a feedback mechanism where the relay terminal device periodically reports congestion information to the network device, and the network device uses this feedback to adjust transmission parameters. This feedback loop enables dynamic congestion control optimization while managing signaling overhead through periodic rather than continuous reporting.
2Loss of energy
If the relay terminal device reports congestion information periodically or based on conditions, then signaling overhead is reduced, but the real-time congestion control response may be delayed
Solution Approach 1:
The patent implements dynamic reporting mechanisms where the relay terminal device adjusts its reporting frequency and timing based on actual network conditions. The system can switch between periodic reporting, event-triggered reporting (when congestion thresholds are crossed), or on-demand reporting based on network status. This dynamic approach optimizes the balance between signaling overhead reduction and real-time response capability.
Solution Approach 2:
The patent employs periodic reporting as a fundamental mechanism where the relay terminal device transmits congestion information at predetermined intervals or when specific conditions are met. This periodic action enables the network device to receive timely congestion updates while controlling signaling overhead by reporting only at necessary intervals rather than continuously.
Data Source
AI summary
Embodiments of this application provide a communication method, a communication device, a computer-readable storage medium, and a computer program product. The communication method includes: determining first information, where the first information includes first congestion indication information, the first congestion indication information indicates congestion information of a relay terminal device, and the relay terminal device provides a relay service between a remote terminal device and a network device; and sending the first information to the network device. In this manner, congestion control related information reported by the relay terminal device can be directly obtained in a data transmission process, so that corresponding configuration update or traffic control is performed based on the reported congestion indication information, to avoid or reduce congestion on the relay terminal device.
