Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to efficiently support multiple connectivity services from a remote User Equipment (UE) in a wireless communication system, particularly in scenarios where traditional mobile voice communication networks are evolving to handle IP data packet communication.
Innovation Solution
The method involves a remote UE establishing a PC5 unicast link with a Layer-2 UE-to-Network relay UE, enabling the remote UE to establish multiple connectivity services with various data networks over the same PC5 unicast link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a remote UE establishes multiple connectivity services with multiple data networks, then service versatility and data throughput are improved, but device complexity and resource management difficulty increase
Solution Approach 1:
The patent segments the complexity by introducing a relay UE that acts as an intermediary between the remote UE and multiple data networks. The relay UE handles the complex interactions with multiple networks, while the remote UE only needs to manage connectivity through the relay, thus segmenting the system into simple remote UE-relay UE-network components that reduces overall device complexity while maintaining service versatility
Solution Approach 2:
The relay UE serves as an intermediary entity that mediates between the remote UE and multiple data networks. It manages the multiple connectivity services, handles network protocols, and coordinates resource allocation, thereby shielding the remote UE from complexity while enabling access to multiple diverse services simultaneously
2Productivity
If a remote UE establishes multiple connectivity services over a PC5 unicast link, then data throughput and service capability are improved, but resource management complexity and link stability requirements increase
Solution Approach 1:
The patent merges multiple connectivity services into a single PC5 unicast link between the remote UE and relay UE. Instead of establishing separate physical links for each service, multiple data networks are accessed through the unified relay UE connection, consolidating resource management while enabling high throughput for multiple services simultaneously
Solution Approach 2:
The PC5 unicast link through the relay UE is designed as a universal interface that can handle multiple connectivity services simultaneously. The relay UE provides multi-functional capabilities, managing voice over IP, multimedia, and data services through a single link, thereby improving data throughput without proportionally increasing resource management complexity
3Adaptability or versatility
If traditional mobile voice communication networks evolve to handle IP data packet communication, then service capability and adaptability are improved, but system complexity and protocol compatibility challenges increase
Solution Approach 1:
The relay UE acts as an intermediary that handles protocol translation and compatibility between traditional mobile networks and modern IP data packet communication systems. It manages the evolution transition by mediating between legacy voice communication infrastructure and contemporary IP-based services, enabling enhanced service capability while containing system complexity within the relay function
