Mobile Base Station Handover via Dual Candidate Lists
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in wireless communications is to quickly and efficiently handover users from a mobile base station that needs to leave a service area to another mobile base station without causing service interruptions, especially in emergency situations where the original mobile base station cannot continue providing service.
Innovation Solution
The solution involves maintaining two candidate lists of neighbor nodes for each mobile base station, which are updated periodically, to quickly determine a suitable replacement base station based on factors like power, capability, and movement trace, ensuring seamless handover and reducing time delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile base station needs to leave its service area due to emergency or other reasons, then the mobile base station can respond to emergency events and provide flexible service coverage, but the user group originally served by the mobile base station will suffer service interruption
Solution Approach 1:
The system pre-establishes a candidate list containing multiple potential replacement base stations before the mobile base station needs to leave. This preliminary preparation ensures that when handover is needed, the system can immediately select from pre-identified candidates without delay, thus maintaining service continuity while enabling mobile base station mobility.
2Productivity
If the mobile base station handover process is simplified to reduce complexity, then the handover operation becomes faster and more efficient, but the success rate of handover may decrease
Solution Approach 1:
The system pre-identifies and stores multiple candidate base stations in a candidate list before actual handover is needed. This preliminary action reduces the complexity and time required for handover decision-making while maintaining high success rates, as the system only needs to select from pre-validated candidates rather than performing complex real-time evaluation.
Solution Approach 2:
The system incorporates feedback mechanisms to monitor and evaluate handover performance. By analyzing handover success rates and adjusting the candidate selection criteria accordingly, the system optimizes the balance between handover speed and success rate, ensuring reliable service continuity during mobile base station relocation.
3Reliability
If the system maintains multiple candidate lists for each mobile base station, then the handover success rate and speed are improved, but the device complexity increases
Solution Approach 1:
The system pre-establishes and maintains candidate lists containing potential replacement base stations. This preliminary organization of data reduces the complexity of real-time handover decisions, as the system only needs to select from pre-compiled lists rather than performing complex real-time searches and evaluations across the entire network.
