Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a service-based architecture framework is implemented with multiple user plane functions, then service management efficiency and network flexibility are improved, but device complexity and network architecture complexity increase
Solution Approach 1:
The patent segments the core network into multiple independent user plane functions (UPFs) that can be independently managed and deployed. Each UPF handles specific user plane tasks, allowing the network to scale and adapt without requiring complete architectural redesign, thus improving service management efficiency while controlling complexity through modular design
Solution Approach 2:
The service-based architecture framework implements universal service management capabilities that can handle multiple network services and functions through a common architecture. This multi-functionality allows the same framework to support diverse services (e.g., enhanced mobile broadband, ultra-reliable low-latency communication, massive machine type communication) without requiring separate dedicated systems for each service type
2Adaptability or versatility
If network slicing is implemented to provide tailored network services, then adaptability and service customization are improved, but device complexity and resource management complexity increase
Solution Approach 1:
The patent implements network slicing by segmenting the physical network infrastructure into multiple virtual networks, each optimized for specific service requirements. This segmentation allows different slices to have customized resource allocations, QoS parameters, and routing policies while sharing the underlying physical infrastructure, thereby achieving service customization without proportionally increasing overall system complexity
Solution Approach 2:
The framework enables dynamic adjustment of network parameters (such as bandwidth allocation, latency thresholds, and resource priorities) for different network slices based on service requirements. This parameter-based customization allows flexible adaptation to diverse service needs while maintaining manageable complexity through standardized parameter sets and configuration mechanisms
3Reliability
If a quality of service model is implemented to prioritize data exchange, then service quality and user satisfaction are improved, but device complexity and control mechanism complexity increase
Solution Approach 1:
The patent implements QoS management by applying different quality levels and service priorities to specific local network segments, user groups, or service types rather than uniformly across the entire network. This localized QoS approach allows critical services to receive enhanced treatment in specific network regions while avoiding the complexity of global QoS control mechanisms
Solution Approach 2:
The framework incorporates feedback mechanisms that continuously monitor network conditions, service quality metrics, and resource utilization, then dynamically adjust QoS parameters and routing decisions. This feedback-driven control automates complex QoS management tasks, reducing the need for manual configuration and simplifying overall control mechanism complexity while maintaining high service quality
Data Source
AI summary
A first wireless device comprises one or more processors and memory storing instructions. When executed by the one or more processors, the instructions cause the first wireless device to: receive, from a second wireless device, a sidelink announcement message comprising a relay service code (RSC) indicating that the second wireless device supports relay of an emergency service to a network; and based on a cell supporting the emergency service not being available to the first wireless device, send, to the second wireless device, a sidelink connection request message comprising the RSC.
