User Equipment Localized Service Registration in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3GPP systems lack a mechanism for User Equipment (UE) to obtain localized services from a hosting network without prior subscription, limiting access to localized services.
Innovation Solution
The proposed method involves a UE receiving broadcast support information from a hosting network, performing manual selection of the hosting network, sending a localized service registration request, and obtaining temporary subscription information to access localized services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UE requires prior subscription to access localized services from a hosting network, then network security and service authorization are improved, but service accessibility and user convenience deteriorate
Solution Approach 1:
The hosting network pre-generates and stores temporary subscription data for multiple UEs before they actually need access. When a UE arrives, the network can quickly allocate pre-prepared subscription credentials without requiring real-time authentication with external networks, thus maintaining security while enabling rapid access
Solution Approach 2:
The patent introduces a temporary subscription mechanism as an intermediary between the UE and the hosting network services. This temporary subscription acts as a mediator that allows UEs without prior subscriptions to access localized services temporarily, bridging the gap between security requirements and access needs
2Measurement precision
If a UE performs manual selection of hosting network, then service localization accuracy is improved, but network selection time and complexity increase
Solution Approach 1:
The UE autonomously performs manual network selection based on broadcast information without requiring complex network-controlled selection procedures. The UE itself evaluates the broadcast support information and makes the selection decision, simplifying the process while achieving accurate localization
Solution Approach 2:
The hosting network broadcasts only the essential support information needed for manual selection (such as service availability indicators) rather than complete network configuration data. This partial information transmission enables UE to make quick selection decisions without processing excessive data
