UE Unified Access Control Subscription Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in efficiently processing call requests when a user equipment (UE) is barred, leading to resource wastage and user frustration due to unutilized input and battery consumption.
Innovation Solution
A UE is configured to receive input associated with a call request and perform a unified access control (UAC) check, selecting a suitable subscription based on barring factors and times to prevent unnecessary call attempts and conserve resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE performs UAC check and selects subscription based on barring parameters, then call processing efficiency is improved, but device complexity increases
Solution Approach 1:
The UE performs the UAC check and selects the appropriate subscription in advance, before actually initiating the call. This preliminary action prevents unnecessary call attempts and resource consumption, improving call processing efficiency while the complexity is managed by automating the selection process based on pre-configured barring parameters
Solution Approach 2:
The UE autonomously performs the UAC check and subscription selection based on its own stored barring parameters, without requiring external intervention or complex network coordination. This self-service approach improves efficiency by enabling rapid local decision-making while keeping device complexity manageable through standardized procedures
2Use of energy by moving object
If the UE prevents input when calls are barred, then battery consumption is reduced, but user experience deteriorates
Solution Approach 1:
The system provides feedback to the user about the barred status and automatically manages the input prevention. The UE monitors the UAC barring status and communicates this information to the user, while automatically preventing further input attempts during the barring period. This feedback mechanism reduces battery consumption by avoiding continuous processing of blocked inputs while maintaining user experience through transparent communication of the system state
3Ease of operation
If the UE processes call requests without UAC check, then ease of operation is improved, but resource wastage increases
Solution Approach 1:
The UE performs the UAC check in advance, before processing the call request. This preliminary verification ensures that the UE only processes calls that are likely to succeed, preventing wastage of processing resources, memory, and battery power on doomed attempts. The ease of operation is maintained because the check is automated and transparent to the user
Solution Approach 2:
The UE performs a partial check (UAC check) that is sufficient to filter out obviously barred calls without requiring full processing. This partial action approach balances ease of operation with resource conservation by implementing a lightweight preliminary filter before committing significant resources to call processing

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a user, input associated with a call request. The UE may select a first subscription, of at least two subscriptions associated with the UE, based at least in part on at least one parameter associated with a unified access control (UAC) check for the call request. Additionally, or alternatively, the UE may display, on a screen of the UE, an indication that the call request is barred based at least in part on the UAC check. Numerous other aspects are described.
