Non-Public Network Selection Using Time and Location Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient methods for a user equipment (UE) to prioritize and selectively access non-public networks (NPNs) based on time and location conditions, limiting access to localized services and failing to manage load balancing effectively.
Innovation Solution
A UE is configured with a set of NPNs that includes time and location conditions, allowing it to prioritize and selectively access NPNs that meet these conditions, thereby facilitating access to localized services and managing load balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a UE scans for all available networks without prioritization, then network coverage is maximized, but access efficiency and service availability deteriorate due to inability to prioritize NPNs with time and location conditions
Solution Approach 1:
The UE is pre-configured with a prioritized list of NPNs including their identifiers, time conditions, and location conditions before network scanning. This preliminary configuration enables the UE to efficiently evaluate and select appropriate NPNs during scanning operations, resolving the contradiction between access efficiency and service availability by having selection criteria ready in advance
Solution Approach 2:
The network selection process becomes dynamic by continuously evaluating current time and location against the pre-configured NPN conditions. The UE can adaptively switch between different NPNs based on real-time condition satisfaction, maintaining both high access efficiency through prioritization and service availability through conditional adaptability
2Adaptability or versatility
If the UE accesses all NPNs without condition-based filtering, then service coverage is improved, but system overhead and resource consumption worsen due to unnecessary scanning and registration attempts
Solution Approach 1:
Instead of uniformly scanning all NPNs, the UE applies local quality filtering by evaluating each NPN's time and location conditions against current UE state. This selective approach ensures scanning and registration resources are consumed only for NPNs that can actually provide service, reducing overhead while maintaining service coverage
Solution Approach 2:
The UE performs partial scanning by focusing only on NPNs whose conditions are currently satisfied, rather than exhaustively scanning all possible NPNs. This partial action approach reduces energy consumption and overhead while still achieving comprehensive service coverage through conditional selection
3Device complexity
If the UE uses static network selection without time and location conditions, then device complexity is reduced, but load balancing and resource management capabilities deteriorate
Solution Approach 1:
The network selection functionality is segmented into distinct components: a configuration module that stores prioritized NPN lists with conditions, and an evaluation module that checks current time and location against these conditions. This segmentation manages device complexity by organizing functions into manageable modules while enabling sophisticated load balancing through conditional network selection

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may receive a configuration indicating a set of non-public networks (NPNs), wherein the configuration includes at least one of: a time condition for accessing the set of NPNs, or a location condition for accessing the set of NPNs. The apparatus may scanning for the set of NPNs based at least in part on the configuration. The apparatus may register with an available NPN, of the set of NPNs, based at least in part on the time condition or the location condition being met for the available NPN. Numerous other aspects are described.
