Network Device Service-Level Identifier Provisioning for 5G UE Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) in 5G/NR networks cannot determine whether a user is subscribed to a specific level of service, despite being able to assess the achievable peak data rate, which affects the display of appropriate network connection icons and service levels.
Innovation Solution
A network device monitors communication sessions, determines a service-level identifier based on performance metrics, and provides this identifier to the UE, enabling it to display the correct service level indication, using a subscription server and MNO provisioning system to manage and authenticate subscriptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE determines achievable peak data rate based on network connection, then the UE can assess network performance capability, but the UE cannot determine whether the user is subscribed to a specific level of service
Solution Approach 1:
The patent introduces a network device as an intermediary between the UE and the subscription server. The network device receives subscription information from the subscription server and provides it to the UE, enabling the UE to determine service level without directly accessing the subscription server. This resolves the contradiction by adding an intermediary component that bridges the information gap.
Solution Approach 2:
The system is segmented into distinct functional components: the UE for determining service level, the network device for managing subscription information, and the subscription server for storing subscription data. This segmentation allows each component to perform its specific function, with the network device acting as a bridge to provide subscription information to the UE, thereby resolving the information access limitation.
2Ease of manufacture
If the UE displays network connection icons based on achievable peak data rate, then the UE can indicate network type, but the UE cannot display accurate service level indication
Solution Approach 1:
The system implements a feedback mechanism where the network device provides subscription information to the UE based on the UE's network connection status. The UE then uses this feedback information to accurately determine and display the service level indication, resolving the contradiction between ease of implementation and accuracy of service level display.
3Adaptability or versatility
If the network provides multiple levels of service, then the network can offer differentiated quality of service, but the UE lacks the information to identify the subscribed service level
Solution Approach 1:
The network device serves as an intermediary that receives subscription information from the subscription server and provides it to the UE. This intermediary mechanism enables the UE to access subscription status information without direct access to the subscription server, thereby resolving the information loss while maintaining service level differentiation capability.

AI summary
In some implementations, a network device may monitor a communication session associated with a user equipment and a network. The network device may determine a service-level identifier associated with a subscription of the user equipment, wherein the subscription is for a particular level of service that is to be provided by the network to the user equipment. The network device may determine that a performance metric associated with the communication session satisfies a performance threshold associated with the particular level of service. The network device may provide the service-level identifier to the user equipment based on the performance metric satisfying the performance threshold, wherein the service-level identifier enables an indication that the user equipment is receiving the particular level of service to be displayed by the user equipment.
