Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hierarchical architecture with centralized back-end devices is used, then system stability and centralized control are improved, but resource utilization efficiency deteriorates due to duplicative processing
Solution Approach 1:
The patent segments the centralized back-end processing into multiple distributed core network services. Each service handles specific processing tasks independently, eliminating duplicative processing across centralized devices. The segmentation allows UEs to connect to only the services they need, improving resource utilization while maintaining system stability through distributed architecture.
2Stability of the object's composition
If centralized back-end devices are used, then centralized control is improved, but power consumption increases due to duplicative processing across multiple devices
Solution Approach 1:
The patent divides centralized control functions into distributed core network services, where each service performs specific control tasks. This segmentation eliminates duplicative processing across multiple centralized devices, reducing overall power consumption while maintaining effective control through the distributed service architecture.
Solution Approach 2:
The patent extracts control functions from centralized back-end devices and places them into distributed core network services. This extraction allows control capabilities to be distributed closer to where they are needed, reducing the energy burden on centralized devices and eliminating redundant processing across the network.
3Device complexity
If hierarchical architecture is used, then system structure simplicity is improved, but adaptability to customized services deteriorates due to centralized ownership
Solution Approach 1:
The patent segments the network into distributed core network services that can be independently configured and customized. Each service can be tailored to specific needs without affecting the entire system, enhancing adaptability while maintaining relative structural simplicity through modular service units.
Solution Approach 2:
The patent creates a universal service-based architecture where core network services can fulfill multiple functions. Each service can be customized for different purposes while following common protocols and interfaces, enabling both simplified structure and high adaptability to customized services.
4Productivity
If distributed core network services are implemented, then resource utilization is optimized, but connection establishment complexity increases
Solution Approach 1:
The patent introduces a service management function as an intermediary that handles connection establishment between UEs and distributed core network services. This mediator manages the complexity of service discovery, selection, and connection setup, allowing UEs to connect efficiently to appropriate services while the intermediary handles the underlying complexity of the distributed architecture.
Data Source
AI summary
Methods, systems, and devices for wireless communications are described. In the context of a service-based wireless system, a user equipment (UE) may identify (e.g., via signaling from the network or based on a subscriber identity module (SIM)) a set of core network services offered by a service-based network that interfaces with a radio access network (RAN) associated with the network entity. Each of the respective core network services may be associated with a corresponding network address. The UE may transmit a service request to a network address associated with a core network service included within the set of offered core network services, and may receive a service context for communicating with the core network service in response to the service request. The UE may then communicate service messages with the core network service (via the network entity) in accordance with the received service context.
