Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mix of wireless devices with varying capabilities and technologies is supported, then network versatility and adaptability improve, but network complexity and difficulty of management increase
Solution Approach 1:
The patent applies segmentation by dividing the network into multiple network slices, each optimized for specific device types, technologies, or service requirements. This allows the network to handle diverse device capabilities through specialized segments rather than a monolithic complex system, resolving the contradiction by organizing versatility into manageable segments.
Solution Approach 2:
The patent implements universality through a service-based architecture that provides common management functions across all network slices and device types. This universal framework handles diverse devices through standardized interfaces and procedures, allowing the network to maintain versatility while reducing management complexity through unified control mechanisms.
2Productivity
If service-based architecture with network slicing is implemented, then resource allocation efficiency improves, but system complexity increases
Solution Approach 1:
The patent segments network resources into dedicated slices that can be independently managed and allocated. Each slice contains specific resources and functions tailored to particular service requirements, enabling efficient resource allocation through specialized segments while the overall system complexity is managed through modular design.
Solution Approach 2:
The patent introduces service-based architecture components as intermediaries that manage network slicing and resource allocation. These intermediary elements provide standardized interfaces and control mechanisms that simplify the management of complex sliced networks, allowing efficient resource allocation without proportionally increasing operational complexity.

AI summary
A session management function (SMF) of a first network receives an indication that a first connection of a wireless device with the first network is used to establish a second connection of the wireless device with a second network. The SMF sends, to the wireless device and based on the indication, a message indicating that the first connection is granted an always-on status.
