Solution Overview
Problem
Existing wireless communication systems face challenges in expanding network coverage in areas with poor cellular signal quality or no coverage, necessitating the deployment of user equipment to network (U2N) relays to enable communication services for UEs.
Innovation Solution
A method and communication device that facilitate the transmission of information about recommended U2N relays to user equipment (UEs), allowing them to select high-quality U2N relays for stable communication, including mechanisms for timely relay information delivery based on UE location and area of interest, and reducing signaling overhead through policy and charging control rules.

Engineering Contradiction Analysis
1Area of stationary object
If U2N relays are deployed to expand network coverage in areas with poor cellular signal quality, then network coverage and service continuity are improved, but signaling overhead and system complexity increase
Solution Approach 1:
The patent introduces a network device as an intermediary that manages and coordinates U2N relay operations. This intermediary handles the complex tasks of relay selection, configuration, and management, thereby reducing the overall system complexity while enabling expanded network coverage through U2N relays.
Solution Approach 2:
The patent employs parameter changes by dynamically adjusting relay selection criteria, configuration parameters, and operational settings based on network conditions. This allows the system to adapt to different coverage scenarios and manage complexity through flexible parameter optimization rather than rigid structural changes.
2Reliability
If U2N relays are deployed to enable communication services in areas with no cellular coverage, then service continuity is improved, but signaling overhead increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring U2N relay parameters, selection criteria, and operational settings before they are needed. This allows the system to quickly deploy relays in areas with no coverage without extensive real-time signaling, thereby maintaining service continuity while reducing signaling overhead.
Solution Approach 2:
The patent enables self-service mechanisms where U2N relays and user equipment can autonomously perform certain operations such as relay selection and configuration based on pre-defined criteria. This reduces the need for continuous network signaling while ensuring reliable service continuity in coverage-free areas.
3Measurement precision
If recommended U2N relay information is transmitted to all UEs, then relay selection quality is improved, but unnecessary signaling and interference increase
Solution Approach 1:
The patent implements local quality by transmitting recommended U2N relay information selectively to specific user equipment based on their location, service requirements, and network conditions. This targeted approach maintains high relay selection quality for relevant UEs while minimizing unnecessary signaling and interference to other devices.
Solution Approach 2:
The patent applies partial action by providing relay information to only those UEs that actually need it, rather than broadcasting to all UEs. This selective information delivery maintains precision in relay selection for targeted devices while reducing overall signaling overhead and interference in the network.
