Mobile Base Station Handover via Advance Resource Reservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular telecommunications networks, mobile base stations face challenges in maintaining Quality of Service (QoS) during handovers due to the lack of advance resource reservation and configuration with neighboring base stations, leading to potential disruptions in service.
Innovation Solution
A method where a mobile base station configures its transmissions in advance of arrival at a target donor base station by requesting and reserving resources based on determined configuration parameters, ensuring continuity of QoS by establishing wireless connections through WLAN or cellular networking interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile base station performs handover without advance resource reservation, then the handover process is simpler and faster to initiate, but the Quality of Service (QoS) continuity is disrupted and service interruptions occur
Solution Approach 1:
The mobile base station determines configuration parameters of neighboring base stations in advance and reserves necessary resources before the actual handover occurs. This preliminary configuration includes identifying target base stations, determining their parameters, and securing resources to ensure seamless QoS continuity during handover, eliminating service interruptions while maintaining manageable complexity through automated advance preparation
2Reliability
If a mobile base station configures transmissions in advance with target donor base station, then QoS continuity is maintained during handover, but the time and signaling overhead for handover preparation increases
Solution Approach 1:
The system performs configuration parameter determination and resource reservation in advance of the actual handover event. By identifying target base stations and securing resources before handover execution, the system ensures service continuity while the automated nature of this preliminary configuration minimizes the perceived preparation time and overhead during the critical handover moment
3Productivity
If a mobile base station requests and reserves resources in advance, then resource availability is guaranteed for seamless handover, but the signaling overhead and network complexity increase
Solution Approach 1:
The mobile base station initiates resource reservation and configuration parameter determination in advance of handover, sending necessary requests to target base stations and the network. This advance resource securing ensures that when handover occurs, all resources are already allocated and configured, maximizing handover efficiency while the automated resource management minimizes ongoing signaling complexity
Solution Approach 2:
The mobile base station autonomously determines configuration parameters of neighboring base stations and manages its own resource reservation requirements. By self-identifying target base stations and self-managing resource allocation requests, the system reduces the need for complex centralized coordination, thereby improving handover efficiency while limiting the increase in network signaling complexity
