Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network resources are continuously activated to support high bit-rates in 5G networks, then network capacity and service availability are improved, but energy consumption increases significantly
Solution Approach 1:
The patent implements dynamic network resource activation and deactivation based on real-time traffic conditions. Network resources such as radio access network elements are activated when traffic demand exists and deactivated when traffic is low, transforming the static continuous operation model into a dynamic adaptive model that adjusts resource states according to actual network conditions
Solution Approach 2:
The system changes the operational state parameter of network resources between active and deactivated states based on traffic conditions. By modifying the operational parameter (on/off state) rather than maintaining constant activation, the system achieves energy savings while preserving network capacity when needed
2Use of energy by moving object
If network resources are deactivated to reduce energy consumption during low traffic periods, then energy efficiency is improved, but network service availability deteriorates
Solution Approach 1:
The system performs preliminary assessment of traffic conditions and network state before deactivating resources. By evaluating current traffic levels and predicting future demands, the system ensures resources are deactivated only when appropriate, preventing service availability issues while maintaining energy efficiency
Solution Approach 2:
The patent implements a feedback mechanism that continuously monitors network traffic conditions and resource states. This feedback loop enables the system to detect when resources should be reactivated based on changing traffic patterns, ensuring service availability is maintained while optimizing energy consumption
3Use of energy by moving object
If user equipment is transferred between networks using roaming model, then energy consumption is reduced, but network complexity increases
Solution Approach 1:
The roaming model implementation creates a universal framework that can be applied across different network configurations and scenarios. The same roaming mechanisms and protocols are used regardless of specific network topology or traffic patterns, reducing the need for custom complex solutions and enabling energy-efficient resource sharing across multiple networks

AI summary
Systems and methods to dynamically transfer user equipment (UE) within telecommunication networks using a roaming model. One system may include a processing system comprising one or more electronic processors. The processing system may be configured to access first network data for a cell of a home network servicing a set of UE. The processing system may be configured to determine, based on the first network data, whether a first condition of the roaming model is satisfied. The processing system may be configured to, responsive to the first condition being satisfied, facilitate a first transfer of the set of UE from the home network to a partner network, and control a plurality of network resources for the cell of the home network.
