AMF-Based SMF Selection for Shared-UE User Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to provide user-customized network services due to reliance on subscriber information alone, leading to discrepancies between desired and provided services, especially in scenarios where multiple users or devices share a single UE.
Innovation Solution
Storing user profile information alongside subscriber information in the network and using a user ID to facilitate the generation of PDU sessions tailored to the actual user's preferences, enabling personalized network services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If subscriber information alone is used for network service provision, then system complexity is reduced, but service customization capability deteriorates
Solution Approach 1:
The patent segments user identification into two independent components: subscriber information (for authentication) and user profile information (for customization). This segmentation allows the system to maintain basic functionality while enabling customization without increasing overall system complexity, as the user profile store operates independently from the core network functions.
Solution Approach 2:
The patent introduces a user profile store as an intermediary component between the UE and the core network. This intermediary stores user-specific customization data and makes it available to network functions during session establishment, enabling service customization without requiring fundamental changes to the core network architecture.
2Adaptability or versatility
If multiple users share a single UE, then device utilization is improved, but service differentiation capability deteriorates
Solution Approach 1:
The patent applies local quality by storing user-specific profile information (QoS preferences, service requirements) for each individual user in the user profile store. During PDU session establishment, the network retrieves the profile corresponding to the specific user identifier, enabling differentiated services for each user while they share the same UE, without requiring separate physical devices.
3Measurement precision
If user profile information is stored in the network, then service relevance is improved, but information storage requirements worsen
Solution Approach 1:
The patent extracts user customization information from the core network functions and places it in a dedicated user profile store. This extraction isolates the storage requirement from the main network infrastructure, allowing precise user identification and customization while managing information storage requirements separately from core network resources.
Data Source
AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to an embodiment, a method performed by an AMF entity in a mobile communication system includes receiving, from a UE, a PDU session establishment request message including a user identifier and a request type of a PDU session establishment request; identifying that the request type indicates that the PDU session establishment request is for the user identifier; and selecting an SMF entity associated with a PDU session establishment based on the user identifier.
