Network Data Analytics Correlation via Group Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G specifications lack a method to efficiently correlate network data analytics (NDA) information across multiple terminal devices associated with different subscriptions, making it difficult to obtain comprehensive data for users or groups, such as families or companies.
Innovation Solution
An apparatus and method that associate each terminal device with a group member identifier and a device group with a group identifier, allowing for the collection and correlation of NDA information by sending a group member identifier request, configuring network functions, and aggregating data based on the group association, enabling the return of correlated information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple device subscriptions are handled separately according to current 5G specifications, then each subscription can be managed independently, but it becomes difficult to obtain correlated NDA information across multiple devices associated with the same user or group
Solution Approach 1:
The patent introduces a group identifier as an intermediary element that mediates between multiple device subscriptions and the NDA information collection process. This group identifier acts as a mediator that allows the NWDAF to correlate information across multiple devices without requiring complex direct relationships between each subscription, thus resolving the information loss while managing complexity through a centralized grouping mechanism
Solution Approach 2:
The patent merges multiple device subscriptions under a common group identifier, allowing NDA information from multiple devices to be collected and correlated together. This combining approach enables the system to treat multiple separate subscriptions as a unified group for analytics purposes, thereby preventing information loss while simplifying the management structure
2Measurement precision
If NDA information is collected for each device individually, then device-specific analytics are accurate, but comprehensive group-level analytics cannot be obtained
Solution Approach 1:
The patent segments the NDA information collection process into two distinct phases: first, individual device-level data collection maintains measurement precision for each device; second, group-level correlation aggregates this segmented data using group identifiers. This segmentation allows both accurate device-specific analytics and efficient group-level analytics to coexist by processing data at appropriate granularities
Solution Approach 2:
The patent adds a new dimension of grouping by introducing group identifiers that operate alongside device identifiers. This dimensional addition allows the system to view and process NDA information both at the individual device level and at the group level simultaneously, enabling comprehensive analytics without sacrificing device-specific precision while improving group-level efficiency
3Productivity
If the system supports grouping multiple devices under a single identifier, then correlated NDA information can be obtained efficiently, but the system complexity increases
Solution Approach 1:
The group identifier serves multiple functions simultaneously: it acts as a grouping mechanism for correlation, a subscription identifier for NDA collection, and a linking element between devices and analytics processes. This multi-functionality improves correlation efficiency without proportionally increasing system complexity, as the same identifier structure serves multiple purposes across different system components

AI summary
According to one aspect of the present disclosure, an apparatus for correlating network data analytics, NDA, information for a device group comprising multiple terminal devices is provided, wherein each terminal device is associated with a group member identifier and the device group is associated with a group identifier. The apparatus is adapted to receive an NDA request comprising a group identifier and an NDA specification of NDA information to be collected, to send a group member identifier request comprising the group identifier, and to receive, in response to the group member identifier request, one or more group member identifiers associated with the group identifier. The apparatus is further adapted to configure one or more network functions, NFs, associated with the group member identifiers in accordance with the NDA specification, to obtain, from the one or more NFs, NDA information collected for the group member identifiers based on the NDA specification, and to correlate the NDA information collected for the group member identifiers based on their association with the device group.
