GID Type Parameters for Efficient NPN Network Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 3GPP specifications for Non-Public Networks (NPNs) do not efficiently handle network selection and onboarding for UEs using credentials from external entities, leading to ambiguous GID usage and unnecessary broadcast of information, which affects network capacity and efficiency.
Innovation Solution
Introduce a type parameter associated with the GID in system information to indicate the type of service offered by networks identified by the GID, allowing UEs to efficiently select and access networks without trial-and-error attempts and reducing unnecessary broadcast data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If system information is broadcast frequently and with detailed information to help UEs select networks, then network selection accuracy for UEs is improved, but network capacity and efficiency deteriorate due to increased interference and resource consumption
Solution Approach 1:
The system information is segmented into essential parameters (GID, type parameter) and optional detailed parameters. The segmentation allows UEs to obtain sufficient information for accurate network selection without the network broadcasting all possible details, thus reducing broadcast overhead while maintaining selection accuracy.
Solution Approach 2:
The invention extracts only the critical information elements (GID and type parameter) needed for network selection from the complete set of possible system information. This extraction approach provides UEs with sufficient guidance for network selection while minimizing the broadcast data volume and associated interference.
2Productivity
If system information includes detailed service descriptions to avoid trial-and-error attempts by UEs, then access efficiency is improved, but broadcast data volume increases causing more interference
Solution Approach 1:
The system uses a type parameter to provide localized, specific information about service types associated with each GID. Instead of broadcasting comprehensive service descriptions globally, the invention provides targeted service type information locally at each GID level, enabling efficient network selection without excessive broadcast data.
3Adaptability or versatility
If the network broadcasts comprehensive information about all services and credentials to support multiple services, then service coverage and versatility are improved, but device complexity and information processing requirements increase
Solution Approach 1:
The type parameter serves as a universal indicator that can represent multiple service types (public network services, NPN services, onboarding services, etc.) using a standardized framework. This multi-functional approach allows the system to support diverse services through a single, compact parameter structure rather than requiring separate information elements for each service type.

AI summary
Embodiments herein relate to, for example, a method performed by a radio network node for handling communication in a wireless communications network, wherein the radio network node is preconfigured with group identities and/or type parameters. The radio network node transmits system information with a type parameter associated with a group identity, GID, wherein the type parameter indicates a type of service offered by one or more networks identified by the GID.
