Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication network architectures face challenges in efficiently managing and optimizing the communication between wireless devices and core networks, particularly in terms of service-based architecture, network slicing, and quality of service (QoS) management.
Innovation Solution
The proposed solution involves a service-based architecture within the core network, which includes multiple user plane functions and untrusted access, enabling flexible network slicing and advanced QoS management. This architecture allows for dynamic configuration and optimization of communication paths based on specific service requirements and network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a service-based architecture with multiple user plane functions is implemented, then network flexibility and adaptability are improved, but device complexity increases
Solution Approach 1:
The core network is divided into multiple independent user plane functions (UPFs), each handling specific traffic flows or services. This segmentation allows the network to be configured flexibly for different services while keeping each individual UPF relatively simple, resolving the contradiction between overall network flexibility and individual component complexity.
Solution Approach 2:
The service-based architecture implements universal interface standards and protocols that allow different UPFs to perform multiple functions through standardized service exposure. This enables a single UPF to serve multiple purposes (e.g., traffic routing, quality of service enforcement, charging) without increasing structural complexity, thereby improving adaptability while maintaining manageable device complexity.
2Productivity
If dynamic configuration and optimization of communication paths is enabled, then network efficiency and productivity are improved, but measurement and detection difficulty increases
Solution Approach 1:
The architecture implements feedback mechanisms where network functions continuously monitor traffic conditions, path performance, and service requirements. Based on this feedback, the system dynamically adjusts communication paths and resource allocation. This automated feedback loop improves network efficiency while reducing the manual measurement and detection burden through systematic monitoring and self-optimization.

AI summary
A wireless device receives, from an access and mobility management function (AMF) in a first non-access stratum (NAS) message, parameters comprising a reporting configuration for a deterministic network (DetNet) node. The wireless device sends, to the AMF and based on the parameters, a second NAS message comprising a report for the DetNet node.
