UE Steering of Roaming for Non-Public Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G networks face challenges in enabling user equipment (UE) to connect to non-public networks (NPNs) while meeting specific time and location requirements, which is crucial for hosting events or providing localized content.
Innovation Solution
The method involves a user equipment (UE) receiving a steering of roaming update from a home public land mobile network (h-PLMN), configuring it to connect to a non-public network (NPN) when time and location requirements are met, and establishing a session with the NPN. The UE can maintain dual connectivity with the h-PLMN and switch back when requirements are no longer met, with the steering of roaming record being coordinated between the NPN and h-PLMN.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continuously monitors location and time requirements to access NPN, then access reliability is improved, but device complexity and power consumption increase
Solution Approach 1:
The network pre-configures the UE with steering of roaming records containing NPN access criteria, location requirements, and time requirements before the UE needs to access the NPN. This allows the UE to have access information ready in advance, reducing the complexity of real-time decision-making while maintaining reliable access when conditions are met.
Solution Approach 2:
The UE autonomously evaluates whether current location and time meet the pre-configured NPN access requirements using its own location tracking capabilities and clock. This self-service approach eliminates the need for continuous network interrogation, reducing device complexity and power consumption while ensuring reliable access when conditions are satisfied.
2Stability of the object's composition
If the UE maintains dual connectivity with h-PLMN and NPN simultaneously, then service continuity is improved, but device complexity increases
Solution Approach 1:
The UE dynamically manages its connectivity state between h-PLMN and NPN based on real-time evaluation of location and time requirements. When NPN access conditions are met, the UE establishes dual connectivity; when conditions are no longer met, the UE releases NPN connectivity and returns to h-PLMN only mode. This dynamic state management ensures service continuity while adapting device complexity to actual needs.
3Measurement precision
If the network provides detailed location-specific and time-specific data for NPN access, then access precision is improved, but information processing overhead increases
Solution Approach 1:
The network provides location-specific data (such as geographic coordinates, area identifiers) and time-specific data (such as start time, end time, duration) that are tailored to the specific NPN and access scenario. The UE applies these localized criteria to evaluate whether current conditions permit NPN access, achieving precise control over NPN accessibility while minimizing unnecessary information processing through targeted, scenario-specific parameters.
