Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional rate limiting methods are used to limit aggregate bit rate, then network resource management is simplified, but the method cannot satisfy current 5G application scenarios and network slice requirements
Solution Approach 1:
The patent segments the network slice configuration at terminal device granularity, allowing independent rate limiting configuration for each network slice. The first network device receives network slice configuration information containing maximum data rate parameters for multiple network slices, enabling fine-grained control that adapts to diverse 5G application scenarios while maintaining manageable complexity through structured configuration.
2Reliability
If maximum data rates are configured for multiple network slices, then service quality differentiation is improved, but resource allocation conflicts may occur
Solution Approach 1:
The patent implements local quality by allowing each network slice to have its own maximum data rate configuration parameters. The first network device determines whether to accept maximum data rates for each network slice independently based on local available resources and local policies, enabling differentiated service quality while optimizing resource allocation through localized decision-making.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting maximum data rate parameters for network slices based on available resources and policies. The first network device can accept, partially accept, or reject maximum data rate requirements for different network slices, allowing flexible parameter modification that balances service quality differentiation with resource allocation efficiency.
3Measurement precision
If detailed network slice configuration is performed, then rate limiting precision is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by having the second network device provide network slice configuration information in advance, including maximum data rate parameters for multiple network slices. This pre-provided configuration allows the first network device to process and make decisions more efficiently, achieving precise rate limiting while reducing processing time through advance preparation of configuration data.
