NWDAF-Based UE Analytics Delivery During Mobility and Roaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in wireless communication systems is the restricted ability to provide information to application servers due to UE movement or roaming, necessitating a method to collect and analyze data on user equipment (UE) and deliver it to servers effectively while considering location and network configuration.
Innovation Solution
A method is provided for selecting a network data analytics function suitable for providing requested information by considering the movement location and network configuration of UE, involving a controller that receives requests, determines suitability based on location information, and transmits responses to application functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UE moves or roams in wireless communication system, then coverage and mobility are improved, but ability to provide information to application servers deteriorates
Solution Approach 1:
The patent introduces a network data analytics function (NWDAF) as an intermediary between the mobile UE and application servers. This mediator collects, analyzes, and stores analytics information about UE behavior, location, and network conditions, then provides this processed information to application servers regardless of UE movement status, thereby maintaining information provision reliability during mobility and roaming
Solution Approach 2:
The system performs preliminary data collection and analytics processing while the UE is accessible, storing analytics information in advance in a network repository. This preliminary action ensures that when the UE moves or roams, the application servers can still retrieve previously generated analytics information without requiring real-time UE accessibility
2Productivity
If analytics information is collected and analyzed for UE, then application performance is improved, but system complexity increases
Solution Approach 1:
The patent divides the analytics system into distinct functional modules: data collection entities that gather UE information, a network data analytics function that processes the data, a storage repository for analytics information, and application servers that consume the analytics. This segmentation allows each component to perform its specific function independently, managing system complexity while enabling comprehensive analytics for improved application performance
