Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a User Equipment (UE) is camped on a 5G New Radio (NR) cell and needs to access a 5G Non-Standalone (NSA) cell, the UE must perform inter-RAT measurement and registration, then the network must reconfigure the transition area, which increases network complexity and registration overhead
Solution Approach 1:
The patent applies universality by enabling the 5G NR cell to serve dual purposes: as a standalone cell for 5G SA operations and as a transition area for 5G NSA operations. The network device configures the 5G NR cell to support both SA and NSA access types, allowing it to function universally across different 5G deployment scenarios without requiring separate dedicated cells for each mode.
Solution Approach 2:
The patent implements preliminary action by pre-configuring the 5G NR cell with transition area parameters including NSA cell identifiers, access type indicators, and measurement configuration before any NSA access is attempted. This advance configuration enables the UE to seamlessly transition to NSA mode without requiring complex real-time network reconfiguration or additional registration procedures.
2Reliability
If the network reconfigures the transition area with detailed parameters including cell reselection priority and measurement configuration, then the UE can properly access NSA cells, but the signaling overhead and registration process become more complex
Solution Approach 1:
The network device performs preliminary configuration of all necessary transition area parameters including cell reselection priority, measurement configuration, and access type settings in advance within the 5G NR cell. This pre-configuration ensures that when the UE needs to access an NSA cell, all necessary parameters are already available, eliminating the need for additional registration signaling and reducing access time.
Solution Approach 2:
The UE utilizes the pre-configured transition area parameters stored in its memory to autonomously perform NSA cell selection and access without requiring real-time network assistance or additional registration procedures. The UE self-configures its measurement and reselection behavior based on the previously provided parameters, reducing signaling overhead and access time.
3Adaptability or versatility
If the 5G NR cell is configured to support both SA and NSA access types with transition area parameters, then the UE can seamlessly switch between modes, but the device complexity for parameter management increases
Solution Approach 1:
The 5G NR cell is configured with universal parameters that support both SA and NSA access types through a unified configuration framework. The transition area parameters include an access type indicator that enables the same cell to serve dual purposes, allowing the UE to switch between SA and NSA modes without requiring separate configuration sets for each access type.
Solution Approach 2:
The network device manages parameter complexity by dynamically adjusting specific parameters based on the detected access type. When the UE attempts NSA access, the network activates NSA-specific parameters such as NSA cell identifiers and measurement configurations, while keeping the core 5G NR parameters unchanged. This selective parameter activation simplifies management compared to maintaining entirely separate configuration sets.
