Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network devices support different protocol versions, then device compatibility is improved, but network performance and data transmission capability deteriorate
Solution Approach 1:
The patent implements dynamic capability matching by having the first network device determine the support capabilities of the second network device in real-time, and dynamically selecting appropriate data transmission modes (first mode for capable devices, second mode for incapable devices). This dynamic adaptation resolves the contradiction by allowing the system to switch between compatibility-focused and performance-focused operation based on actual device capabilities.
Solution Approach 2:
The patent changes the transmission parameter (data transmission mode) based on the determined capability parameters of the receiving device. When the second network device is determined to support the first protocol version, the system uses a first transmission mode with higher performance; when it doesn't support the protocol, the system switches to a second transmission mode ensuring compatibility. This parameter adaptation resolves the contradiction between compatibility and performance.
2Adaptability or versatility
If network devices use different protocol versions, then device versatility is improved, but network performance deteriorates
Solution Approach 1:
The system dynamically determines protocol support capabilities and adjusts transmission modes accordingly. The first network device performs capability determination and dynamically selects between first and second data transmission modes, ensuring reliable performance when possible while maintaining protocol support versatility. This dynamic approach resolves the contradiction by making reliability conditional on capability matching.
Solution Approach 2:
The capability determination mechanism acts as an intermediary between protocol diversity and performance reliability. By introducing this intermediate assessment step, the system can mediate between supporting multiple protocol versions (versatility) and ensuring reliable data transmission (performance), selecting the appropriate transmission mode based on the intermediary's assessment of device capabilities.
3Stability of the object's composition
If software updates are not performed on network devices, then device stability is maintained, but new network performance features cannot be supported
Solution Approach 1:
The patent implements a dynamic capability assessment and adaptation mechanism that allows the network to accommodate devices with different feature sets. The first network device determines the capabilities of the second device and dynamically adjusts the transmission mode, enabling the system to maintain stability for legacy devices while supporting new features when both devices are updated. This resolves the contradiction by making feature support dynamic rather than requiring universal updates.

AI summary
A data transmission method, performed by a communication device corresponding to a policy control function entity, includes: obtaining first support capability information indicating whether a first network device supports a first capability for quality of service processing of a data packet set at a first moment; generating a first policy and charging control rule based on the first support capability information; and transmitting the first policy and charging control rule.
