Mobile Network Analytics Using Historical Association Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G systems lack mechanisms to efficiently retrieve historical and current association information for network entities and areas of interest, leading to increased data collection load and incomplete information for analytics generation.
Innovation Solution
Introduce network entities and methods to obtain past and current association information for areas of interest with reduced signaling, allowing flexible data collection from various network entities, including UEs, cells, and network functions, and aggregate this information for analytics generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the NWDAF retrieves information per UE using existing mechanisms, then it can obtain some analytics data, but the data collection load increases significantly and historical information is incomplete
Solution Approach 1:
The UDM performs preliminary actions by maintaining and updating association information between UEs, cells, and network functions in advance. This pre-computed information is stored and made available for quick retrieval by the NWDAF, eliminating the need for the NWDAF to perform complex queries and reducing data collection load while ensuring complete historical and current information is available.
2Loss of information
If the NWDAF searches multiple entities for NF serving information, then it can obtain current NF associations, but historical information is lost and the process becomes complex
Solution Approach 1:
The invention merges the storage and management of association information into a single entity (UDM) that maintains comprehensive records of UE-cell-NF associations over time. This consolidation allows the NWDAF to retrieve both historical and current information from one source through a simplified process, eliminating the need to query multiple entities and ensuring complete information availability.
3Loss of information
If existing UDM mechanisms are used to retrieve NF serving information, then current associations are obtained, but historical association information is not available
Solution Approach 1:
The UDM performs preliminary actions by continuously maintaining and updating association information in advance, storing both historical and current data in a structured manner. This pre-computed and pre-stored information is immediately available for retrieval by the NWDAF, providing complete historical context without complicating the retrieval process.

AI summary
The present disclosure relates to a new generation mobile network, and particularly to the generation of analytics information in the network. To this end, the disclosure proposes a first network entity for generating the analytics information, and proposes a second network entity and a third network entity, respectively, for supporting the analytics generation. The first network entity is configured to obtain, from the second network entity or from one or more third network entities, past and/or current association information for an area of interest. Further, it is configured to provide analytics information based on the obtained association information for the area of interest. The past and/or current association information indicates one or more other network entities and/or network properties that, respectively, have been and/or are mapped to or serving the area of interest.
