Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless charging information is not transferred during cell handover, then base station operations remain simple, but terminal wireless charging continuity is disrupted
Solution Approach 1:
The core network functions as an intermediary to facilitate the transfer of wireless charging information between base stations. The source base station sends the information to the core network, which then forwards it to the target base station, eliminating the need for direct complex communication between base stations while ensuring charging continuity.
Solution Approach 2:
The wireless charging information is transferred from the source base station to the core network in advance of the actual handover execution. This preliminary action ensures that the target base station is already prepared with the necessary charging configuration before the terminal completes the handover, preventing any disruption in charging service.
2Reliability
If wireless charging information is transferred during handover, then charging continuity is maintained, but network signaling overhead increases
Solution Approach 1:
The transfer of wireless charging information is merged with the existing handover signaling process. The information is carried within standard handover message structures (such as Handover Required, Handover Request, and Handover Request Acknowledge messages), combining multiple functions into a single signaling exchange rather than creating separate dedicated signaling procedures.
3Productivity
If base stations independently manage wireless charging, then system simplicity is maintained, but resource utilization efficiency decreases
Solution Approach 1:
The core network's existing handover management infrastructure is made multi-functional by enabling it to also handle wireless charging information transfer. This universal approach allows the same signaling pathways and network elements to serve both handover coordination and charging information dissemination purposes, improving resource utilization without adding dedicated specialized components.
