Data Profile Coordination for Secure Cross-Domain Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing wireless communication systems, there is a lack of effective data collection and sharing mechanisms that protect internal information of the radio access network (RAN) and core network (CN) from exposure during cross-domain data sharing, particularly in scenarios involving user equipment (UE) and radio access network data.
Innovation Solution
A data collection method and apparatus that utilize data profiles to identify and manage data providing and repository nodes, allowing secure data collection and sharing by determining collection state information and using data profiles to reduce unnecessary data transmission and maintain domain isolation, thereby supporting cross-domain data sharing while ensuring data security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is shared across RAN and CN domains using existing protocols, then data sharing capability is improved, but internal information of RAN or CN is exposed
Solution Approach 1:
The patent introduces a Data Collection Coordination Function (DCCF) as an intermediary between data collecting functions (NWDAF, ADRF) and data consuming functions. The DCCF receives data collection requests, determines whether data is being or has been collected by NWDAF or ADRF, and coordinates the data sharing process. This intermediary mechanism enables cross-domain data sharing while protecting internal network information by abstracting away the specific data collection and storage locations from the consuming functions.
2Device complexity
If only NWDAF and ADRF register collected data with DCCF, then data collection coordination is simplified, but other network functions cannot register their collected data
Solution Approach 1:
The patent extends the data registration capability of DCCF to accommodate multiple types of network functions beyond just NWDAF and ADRF. The DCCF is designed to receive data collection information from various network functions in both RAN and CN domains, making it a universal coordination point. This allows different network functions to register their collected data while maintaining a unified coordination mechanism, thus improving versatility without significantly increasing complexity.
3Loss of information
If detailed data collection information is transmitted across domains, then data sharing completeness is improved, but network security is compromised
Solution Approach 1:
The patent extracts only the essential data collection information needed for coordination purposes and transmits it through DCCF, rather than transmitting complete detailed data across domains. The DCCF stores data collection information (such as data identifiers, collection status) without exposing the full data content or internal network structure. This extraction approach maintains data sharing completeness at the information level while protecting network security by not exposing sensitive detailed information.

AI summary
This application discloses a data collection method, a data collection apparatus, a communication device, and a storage medium. The data collection method according to the embodiments of this application includes: determining, by a first function node based on an obtained data profile after receiving a first data request, collection state information of first data requested by the first data request, where the data profile is used for describing information of data that is being collected or has been collected by a data providing function node; and determining, by the first function node based on the collection state information of the first data, a data providing function node for providing the first data or a data repository function node, where the data repository function node is used for storing data collected by the data providing function node.
