Mobile Relay Service Continuity via Sidelink Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile networks, service continuity for user end devices is disrupted when a mobile communication relay experiences a mobility event, leading to fluctuations in signal strength and quality, which can cause service disruptions and affect the Quality of Experience (QoE) for users, especially during media content streaming.
Innovation Solution
The system detects impending mobility events and establishes a direct communication link between the user end device and another mobile communication relay with stronger signal strength using the Sidelink protocol, ensuring seamless service continuity by reconfiguring Radio Resource Configuration (RRC) and maintaining or re-establishing direct communication links before the event occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile communication relay maintains direct communication link with user end device, then service continuity is improved, but signal stability deteriorates during mobility events
Solution Approach 1:
The system performs preliminary actions by detecting mobility events (such as changes in GPS coordinates or cell tower connections) before they fully impact communication quality. When a mobility event is detected, the system proactively initiates link reconfiguration or relay switching procedures to maintain service continuity, rather than waiting for signal degradation to occur.
Solution Approach 2:
The system introduces an intermediary communication relay node that can serve as a backup or alternative path. When the primary relay experiences signal instability during mobility events, the user end device can switch to communicating through a different relay node, maintaining service continuity while bypassing the unstable link.
2Reliability
If the system establishes direct communication link using Sidelink protocol, then service disruption is reduced, but device complexity increases
Solution Approach 1:
The user end device and communication relays perform self-service by autonomously detecting mobility events and executing reconfiguration procedures without requiring manual intervention or complex centralized control. The devices monitor their own signal conditions and automatically switch relays or reconfigure links based on predefined criteria, simplifying the overall system architecture.
Solution Approach 2:
The communication relays are designed with multi-functionality, serving both as standard network nodes and as mobility event detectors. The same relay infrastructure that provides communication services also performs monitoring and triggering of reconfiguration procedures, eliminating the need for separate detection devices and reducing overall system complexity.
