Position-Aware Handover Lists for Mobile Relaying Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User Equipment (UE) in mobile communication devices, such as buses or trains, face challenges in identifying suitable communication devices to connect to when terminating a connection, especially due to positional changes, leading to decreased reception and difficulty in establishing new connections.
Innovation Solution
A relaying system improves the handover list for UE by determining and transmitting a tailored handover list based on its position, destination, communication capabilities, and desired parameters, ensuring seamless connection transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile communication device (bus, train, vehicle) acts as a relaying system, then the UE can maintain connection while moving, but the UE faces challenges in identifying suitable communication devices to connect to when terminating the connection due to positional changes
Solution Approach 1:
The system determines a handover list in advance based on the relaying system's current position and transmits it to the UE before connection termination is needed. This preliminary preparation allows the UE to have suitable handover targets ready when the connection needs to be terminated, resolving the challenge of identifying suitable communication devices at the moment of disconnection.
Solution Approach 2:
The network acts as an intermediary by determining and transmitting the handover list from the relaying system to the UE. This intermediary mechanism provides the UE with pre-identified suitable communication devices, eliminating the need for the UE to independently identify handover targets during connection termination.
2Adaptability or versatility
If the UE receives a generic handover list, then it has potential connection options, but it lacks position-specific optimization for seamless handover
Solution Approach 1:
The handover list is determined specifically for the current position of the relaying system, making the connection options locally optimized for that position. This position-specific approach ensures that the handover list contains communication devices that are actually suitable for handover at that location, improving both applicability and efficiency.
Solution Approach 2:
The handover list is dynamically determined based on the changing position of the relaying system. As the relaying system moves to different positions, new handover lists are determined and transmitted to the UE, ensuring that the handover options remain relevant and effective throughout the movement.
3Adaptability or versatility
If the system determines handover lists for all possible positions, then the UE has comprehensive handover options, but it generates unnecessary communication overhead for non-required positions
Solution Approach 1:
The system extracts and transmits only the position-specific handover list that is currently needed, rather than transmitting all possible handover lists for all potential positions. This selective approach reduces communication overhead while still providing the UE with appropriate handover options for its current and near-future positions.
