Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a service-based architecture is implemented to support diverse wireless devices and technologies, then network flexibility and adaptability are improved, but device complexity and configuration difficulty increase
Solution Approach 1:
The network architecture is segmented into independent service-based functions (user plane functions, control plane functions) that can be selectively activated. Each function operates as a discrete module, allowing the network to compose services dynamically without managing monolithic complex systems, thus improving flexibility while controlling complexity through modular design.
Solution Approach 2:
The service-based architecture implements universal interface standards and protocols that allow the same network infrastructure to support multiple wireless technologies and device types. Common service interfaces enable diverse devices (including UAS) to interact with the network through standardized mechanisms, achieving versatility without proportionally increasing architectural complexity.
2Productivity
If dynamic service selection and configuration is enabled for multiple technologies, then service delivery optimization is improved, but authentication and management complexity increase
Solution Approach 1:
The architecture introduces intermediary service management functions that handle authentication and service selection dynamically. These intermediary components mediate between diverse devices and the core network, implementing complex authentication protocols and service matching logic in a centralized manner, thereby simplifying device-side complexity while enabling efficient service delivery through automated decision-making.
3Adaptability or versatility
If support for unmanned aerial systems and diverse use cases is added, then network versatility is improved, but interference management and coordination difficulty increase
Solution Approach 1:
The network implements dynamic resource allocation and interference coordination mechanisms that adapt in real-time to different use cases including UAS operations. Service functions can dynamically adjust parameters such as frequency allocation, power levels, and spatial coordination based on current network conditions and device requirements, enabling versatile support for multiple technologies while actively managing interference through continuous optimization rather than static configurations.

AI summary
A method may include receiving, by an access and mobility management function (AMF) from a core network node, a request message. The request message may indicate a request for a notification of an altitude change of a wireless device and may also indicate a threshold for determining the altitude change. The method may also include sending, by the AMF to a base station, a location reporting request associated with altitude of the wireless device. The method may further include receiving, by the AMF, a location report associated with the altitude of the wireless device. The method may additionally include sending, by the AMF to the core network node, a report message notifying the altitude change of the wireless device.
