Virtual UE Registration in Inter-Vehicle Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing virtual user equipment (UE) in vehicle-to-vehicle communication, particularly in registering or removing virtual UEs without affecting network configurations such as bearers, and in providing high-quality communication services to moving vehicles with limited infrastructure changes.
Innovation Solution
A method and device for controlling virtual UE in an inter-vehicle communication system, where a UE connects with a base station, receives connection reconfiguration commands, and registers or removes virtual UEs based on these commands, using unique virtual UE indexes for communication, and includes a transceiver module and processor for managing connections and information transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual UE registration is performed through traditional network configuration methods, then communication service can be established, but network configuration complexity increases and infrastructure changes are required
Solution Approach 1:
The patent segments the UE into a real UE and multiple virtual UEs, where the real UE maintains a single RRC connection while virtual UEs are managed through separate virtual identifiers. This segmentation allows virtual UE registration without requiring complex network configuration changes, as each virtual UE is handled independently through virtualization rather than physical network reconfiguration
Solution Approach 2:
The patent introduces a virtual UE management mechanism that acts as an intermediary between the real UE and the network. The real UE receives RRC messages and manages virtual UE registrations through this intermediate layer, preventing direct complex network configuration changes while maintaining reliable communication services for all virtual UEs
2Adaptability or versatility
If traditional UE connection methods are used, then network infrastructure can support communication, but mobility and adaptability to vehicle movement are limited
Solution Approach 1:
The patent implements dynamic virtual UE management where virtual UEs can be registered, activated, and deactivated based on real-time vehicle mobility and communication needs. The system dynamically adjusts which virtual UEs are active without requiring physical infrastructure changes, enabling high adaptability to vehicle movement patterns
Solution Approach 2:
The patent makes the single RRC connection universal by enabling it to serve multiple virtual UEs simultaneously. The real UE's RRC connection handles communications for itself and multiple virtual UEs, making the infrastructure more versatile and adaptable to different mobility scenarios without requiring dedicated connections for each virtual entity
3Productivity
If multiple virtual UEs are registered with a real UE, then communication service coverage increases, but connection management complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the real UE autonomously manages its own virtual UE registrations and RRC connections. The system handles virtual UE management internally without requiring external network intervention for each virtual UE, reducing connection management complexity while expanding service coverage
Solution Approach 2:
The patent creates virtual copies of UE identities and communication interfaces. Each virtual UE is essentially a copied identity that shares the real UE's physical connection resources. This copying approach allows multiple virtual UEs to be managed through simplified virtual identifiers rather than complex physical connection management
Data Source
AI summary
A method by which a user equipment (UE) performing communication controls a virtual UE, includes transmitting, to a base station (BS), at least one of information on the UE or information on a service provided by the UE, wherein the BS determines whether the virtual UE is registered or removed, based on the at least one of the information on the UE or the information on the service provided by the UE; receiving, from the BS, a connection reconfiguration command message, wherein the connection reconfiguration command message includes information on a determination of the BS of whether the virtual UE is registered or removed; and registering or removing the virtual UE based on the information on the determination of the BS included in the connection reconfiguration command message.
