User-ID-Based PDU Session Selection for Customized 5G Services
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 UE.
Innovation Solution
Storing user profile information alongside subscriber information in the network and using a user ID to identify the actual user, enabling the network to provide services tailored to the current user's preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network relies on subscriber information alone to provide services, then the system complexity is reduced, but the service customization and relevance deteriorate
Solution Approach 1:
The patent segments user identification into two distinct components: subscriber information (for authentication and basic service provisioning) and user profile information (for customization and preference-based service delivery). This segmentation allows the network to maintain system simplicity for authentication while enabling sophisticated customization for service delivery, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The patent introduces a user profile database as an intermediary component between the subscriber authentication system and the service delivery system. This intermediary stores and manages user preference information, allowing the network to customize services without increasing the complexity of the core authentication and routing functions. The user profile database acts as a mediator that enables service customization while maintaining system architecture simplicity.
2Adaptability or versatility
If the network stores only subscriber information, then the data storage requirement is reduced, but the ability to provide user-customized services deteriorates
Solution Approach 1:
The patent applies local quality by storing different types of information in different locations with different levels of detail. Subscriber information is stored at the network core level for authentication, while user profile information (preferences, customization parameters) is stored in a dedicated user profile database. This localized storage approach allows the network to store only the necessary customization data for each user without requiring extensive storage for all possible service configurations, thus enabling user-customized services with manageable storage requirements.
3Measurement precision
If the network uses subscriber information for service provision, then the identification process is simplified, but the accuracy of service relevance to the actual user deteriorates
Solution Approach 1:
The patent adds another dimension to user identification by introducing user profile information that captures individual preferences and customization parameters. Instead of relying solely on subscriber information (first dimension), the system incorporates user-specific profile data (second dimension) to accurately identify and serve the actual user. This dimensional expansion enables precise service relevance matching without significantly complicating the identification process, as the additional dimension is integrated into the existing service provisioning workflow.
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.
