Network Slice Icon Policy for Transparent User Experience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network slice management in User Equipment (UE) lacks transparency and differentiation, failing to provide users with clear indications of available high-quality network slices, leading to suboptimal video streaming and gaming experiences due to lack of guaranteed bit rate and quality of service (QoS) and absence of icon policies per application.
Innovation Solution
Implementing a method for the Application Processor (AP) to receive and maintain a list of UE Route Selection Policy (URSP) rules, including network slice selection assistance information, to display icons indicating active network slices, allowing users to benefit from better security, low latency, and higher bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If network slice management is implemented without transparency and differentiation, then device complexity is reduced, but user experience and service quality deteriorate due to lack of clear indications and optimization capabilities
Solution Approach 1:
The patent introduces an intermediary layer (network slice manager and icon policy manager) that sits between the complex network slice infrastructure and the user interface. This intermediary translates complex network slice information into simple, visual icon representations, providing transparency without exposing users to underlying complexity. The intermediary handles the complexity of receiving URSP rules, determining active slices, and managing icon policies internally while presenting a simplified view to users.
2Ease of operation
If icon policies are implemented per application with differentiated network slice indications, then user experience and service quality improve, but device complexity increases due to additional management mechanisms
Solution Approach 1:
The patent segments the network slice indication mechanism into application-specific icon policies. Each application can have its own icon policy configuration that maps to specific network slices (e.g., video streaming apps mapped to high-bandwidth slices, gaming apps mapped to low-latency slices). This segmentation allows differentiated treatment of different applications while maintaining a unified management framework through the icon policy manager.
Solution Approach 2:
The system changes the parameter of network slice indication from a generic, unified approach to application-specific, differentiated indications. By modifying the icon policy parameters to include application identifiers and slice-specific configurations, the system enables users to optimize subscriptions and application performance based on which applications are using which network slices, without requiring complex manual configuration.
3Reliability
If network slice information is made transparent and differentiated, then service quality and user experience improve, but information processing requirements increase
Solution Approach 1:
The patent implements partial action by selectively displaying icon policies only for applications that are currently active or have specific network slice requirements. Rather than continuously processing and displaying information for all possible applications, the system determines and displays icons based on currently active applications and their associated network slices. This reduces unnecessary information processing and energy consumption while maintaining reliability for services that actually require network slice optimization.

AI summary
A method for network slice enhancement for a user equipment (UE) includes receiving, at an application processor (AP) from a modem, a list of UE route selection policy (URSP) rules, one or more network slice selection assistance information (S-NSSAI) associated with one or more network slices categorized among configured network slices, rejected network slices, requested network slices, and allowed network slices, and protocol data unit (PDU) session information, and maintaining, by the AP, a database to store information received at the AP. The one or more network slices execute one or more services at the UE.
