Network Element Authorization for Subscription Data Access

The patent introduces an AMF network element as an intermediary between UE and subscription data storage. The AMF receives requests from UE, verifies authorization status, and selectively forwards requests to ASMF or UDM network elements. This intermediary mechanism enables commercial value realization by allowing authorized access while maintaining information security through controlled authorization verification before data disclosure.

The patent implements preliminary authorization verification where the AMF network element checks whether the UE has authorized subscription service status before forwarding information access requests. By performing this authorization check in advance at the AMF level, the system avoids repeated verification at each data access point, thereby maintaining information security while reducing processing time for subsequent data retrieval operations.

The patent segments the subscription data management system into distinct functional network elements: AMF for access management and authorization verification, ASMF for subscription data storage and management, and UDM for user data management. Each element has a specialized function, which improves system functionality and security through distributed architecture while managing complexity by assigning specific roles to each component rather than requiring all elements to handle all operations.
