Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no QoS guarantee mechanism is implemented in FMSC network, then network complexity is reduced, but service quality consistency and user experience cannot be guaranteed
Solution Approach 1:
The patent segments QoS policies into multiple granular levels (PDU session level, QoS flow level, service level, user level) to enable differentiated service quality guarantees. This segmentation allows the complex QoS management function to be divided into manageable components that can be independently configured and enforced across the FMSC network.
Solution Approach 2:
The patent implements preliminary QoS policy generation and distribution before service activation. The network device generates QoS policies based on service requirements and distributes them to relevant network elements in advance, ensuring that QoS guarantees are already in place before traffic begins, thus avoiding reactive adjustments that would increase operational complexity.
2Reliability
If network-customized QoS policies are generated and distributed to multiple network elements, then QoS guarantee capability is improved, but message processing complexity increases
Solution Approach 1:
The patent designs a universal QoS policy framework that can be applied across multiple network elements (core network, access network, service platform) using common policy structures and protocols. This multi-functionality allows the same QoS mechanism to operate consistently across different network domains without requiring element-specific processing logic, thereby reducing overall message processing complexity.
Solution Approach 2:
The patent introduces QoS policy as an intermediary structure that mediates between service requirements and network resource allocation. By encapsulating QoS parameters in standardized policy messages, the system simplifies communication between diverse network elements, reducing the complexity of direct interactions and enabling more efficient policy distribution and enforcement.
3Adaptability or versatility
If QoS policies are implemented at multiple granular levels, then service differentiation is improved, but policy management complexity increases
Solution Approach 1:
The patent segments QoS policies into multiple granular levels (PDU session level, QoS flow level, service level, user level) to enable differentiated service quality guarantees. This segmentation allows the complex QoS management function to be divided into manageable components that can be independently configured and enforced across the FMSC network.
Solution Approach 2:
The patent implements dynamic QoS policy adjustment mechanisms that allow policies to be automatically modified based on real-time network conditions and service requirements. This dynamic capability enables the system to adapt to changing conditions without requiring manual reconfiguration of all policies, thereby managing complexity through automation while maintaining service differentiation.
4Reliability
If inter-network collaborative management is implemented, then handover service quality is improved, but coordination complexity increases
Solution Approach 1:
The patent implements feedback mechanisms in inter-network collaborative management that enable continuous monitoring of handover performance and QoS parameters. By collecting real-time feedback from network elements during handover processes, the system can automatically adjust coordination parameters and policies to maintain service quality, reducing the need for complex manual coordination protocols.
Solution Approach 2:
The patent implements preliminary QoS policy generation and distribution before service activation. The network device generates QoS policies based on service requirements and distributes them to relevant network elements in advance, ensuring that QoS guarantees are already in place before traffic begins, thus avoiding reactive adjustments that would increase operational complexity.
