UE Configuration Signaling for PLMN-Specific Network Slices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular networks, particularly 5G systems, managing UE configuration for network slices is challenging when the UE has a default configuration that does not align with the specific requirements of the serving network, leading to resource inefficiencies and complexity in managing network configurations across multiple public land mobile networks.
Innovation Solution
The UE detects its default configuration and sends an explicit or implicit indication to the network, allowing the serving network to provide a network-specific configuration, thereby updating the UE's configuration to align with the current network requirements.

1Productivity
If the UE uses a default configuration for all PLMNs, then the UE can access networks quickly without extensive configuration, but the configuration may not align with specific network requirements leading to resource inefficiency
Solution Approach 1:
The UE is pre-configured with a default configuration that can be immediately applied upon entering a PLMN, enabling fast network access without waiting for network-specific configuration. This preliminary configuration ensures basic service availability while the network determines whether to provide optimized network-specific settings.
Solution Approach 2:
The configuration system transitions from static default configuration to dynamic configuration by introducing an indication mechanism. The UE dynamically switches from using default configuration to network-specific configuration based on the network's response to the sent indication, allowing the system to adapt to specific network requirements while maintaining fast initial access.
2Reliability
If the network provides network-specific configuration to all UEs, then optimal network performance is achieved, but the network complexity and management overhead increase
Solution Approach 1:
The UE autonomously manages its configuration state by detecting whether it has a valid network-specific configuration and independently sending an indication to the network when using default configuration. This self-service mechanism reduces the need for complex network-side configuration management while ensuring optimal performance when available.
Solution Approach 2:
The UE sends feedback to the network through an indication message when it is using a default configuration. This feedback mechanism allows the network to identify UEs that may benefit from network-specific configuration without requiring continuous polling or complex management protocols, thereby reducing network management complexity.
3Ease of operation
If the UE sends an explicit indication of using default configuration, then the network can efficiently provide network-specific configuration, but additional signaling overhead is introduced
Solution Approach 1:
The indication that the UE is using a default configuration is extracted and sent separately in a registration request or other appropriate message. This extraction allows the network to efficiently identify UEs needing configuration updates without mixing the indication with other configuration data, improving configuration management efficiency while keeping signaling overhead minimal.
