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 is improved, but device complexity increases
Solution Approach 1:
The patent segments the network architecture into distinct functional units (AMF, SMF, UPF) that can independently handle different device types and communication protocols. This segmentation allows the network to support multiple wireless technologies without requiring a monolithic complex system, as each segment can be optimized for specific device categories.
Solution Approach 2:
The patent implements universal network functions that can serve multiple purposes across different device types. The AMF and SMF can handle both traditional cellular devices and emerging wireless devices through standardized interfaces and protocol handling, allowing a single network infrastructure to support diverse device capabilities without proportionally increasing complexity.
2Adaptability or versatility
If multiple communication protocols are implemented, then adaptability to different technologies is improved, but configuration complexity increases
Solution Approach 1:
The patent introduces intermediary network functions (AMF, SMF) that act as mediators between diverse wireless devices and the core network. These intermediaries translate and adapt different communication protocols into standardized internal formats, allowing multiple protocols to coexist without directly increasing configuration complexity at the device level.
Solution Approach 2:
The patent utilizes parameter-based configuration where network functions can dynamically adjust protocol parameters and behavior based on device capabilities and service requirements. This allows the same network infrastructure to support multiple protocols by changing operational parameters rather than requiring separate complex configurations for each protocol type.
3Adaptability or versatility
If network flexibility is enhanced to support varying device capabilities, then service quality is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic network functions that can adapt their behavior and资源配置 based on real-time device capabilities and service requirements. The AMF and SMF can dynamically select appropriate processing paths, protocol handlers, and resource allocations, providing network flexibility without requiring static complex configurations for all possible device scenarios.
Solution Approach 2:
The patent employs preliminary device capability assessment and network function selection during the initial connection phase. By determining device type and capabilities early in the connection establishment process, the network can pre-configure appropriate service flows and protocol handlers, providing flexibility for diverse devices without requiring complex runtime decision-making or reconfiguration.
Data Source
AI summary
An access and mobility function (AMF) of an overlay network may receive, from a non-3GPP interworking function (N3IWF), a first message. The first message may comprise location information of a wireless device. The AMF may send, to a policy and charging control function (PCF), a second message to establish a policy association for access of the wireless device via an underlay network. The AMF may further receive, from the PCF, policy information for access of the wireless device via the underlay network. The AMF may further send the received policy information to the wireless device.
