Mobile Relay System for Vehicular Signal Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicular communication systems, user equipment (UE) connected to a network via a relay system (RS) often experience reduced network reception due to vehicle structure interference, leading to suboptimal Quality of Service (QoS) when connected to the same mobile service provider as the RS, potentially resulting in a decreased user experience.
Innovation Solution
The method involves obtaining information about the mobile service provider of the UE, establishing a first connection between the UE and the RS to match the provider, and then choosing a network entity from the mobile communication system to establish a second connection, allowing the RS to connect the UE to a network entity with improved QoS, signal strength, or different service provider for enhanced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE connects to the same mobile service provider as the relay system, then connection stability is improved, but Quality of Service deteriorates due to vehicle structure interference
Solution Approach 1:
The relay system acts as an intermediary between the UE and the network entity. It establishes a first connection with the UE inside the vehicle and a second connection with the network entity outside the vehicle, thereby mediating the communication to overcome the blocking effect of the vehicle structure while maintaining connection stability
Solution Approach 2:
The connection path is segmented into two separate connections: the first connection between UE and relay system, and the second connection between relay system and network entity. This segmentation allows each connection to be optimized independently, with the relay system selecting different service providers for each connection to resolve the contradiction
2Adaptability or versatility
If the relay system uses the same service provider as the UE, then network compatibility is improved, but signal strength deteriorates due to vehicle interference
Solution Approach 1:
The relay system changes the service provider parameter for the second connection differently from the first connection. It obtains information about the UE's service provider, establishes the first connection matching the UE's provider for compatibility, then selects a different network entity for the second connection to achieve better signal strength and QoS
3Ease of operation
If the UE remains inside the vehicle, then device portability is maintained, but network reception deteriorates due to vehicle structure blocking
Solution Approach 1:
The relay system with external antennas serves as a mediator that receives signals from the network entity outside the vehicle and relays them to the UE inside the vehicle. This allows the UE to remain portable inside the vehicle while the relay system's external antennas overcome the blocking effect of the vehicle structure
Solution Approach 2:
The solution moves the antenna function to another dimension - from internal UE antennas to external relay system antennas. The relay system positioned outside or on the vehicle surface receives signals in the external environment and relays them internally, effectively bypassing the vehicle structure interference
