5G Network Element Subscription Verification for Direct Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the current 5G system, it is difficult to directly exchange data between network elements in an external network and network elements in the internal 5G core network, leading to reduced efficiency in information obtaining between network elements.
Innovation Solution
The proposed solution involves a method where a first function network element and a second function network element use corresponding subscription rules to enable direct access, allowing data exchange directly between the two network elements, thereby improving information obtaining efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data exchange between external network elements and internal 5G core network elements is performed through the NEF entity, then information security is maintained, but information obtaining efficiency is reduced
Solution Approach 1:
The patent segments the authentication and access control functions from the NEF entity and assigns them to individual network elements. Each network element performs its own authentication and subscription verification, eliminating the need for all data exchanges to route through the NEF entity while maintaining security through distributed verification mechanisms
Solution Approach 2:
The patent implements preliminary authentication and subscription verification before data exchange occurs. Network elements perform authentication in advance and establish access permissions beforehand, allowing direct efficient communication while maintaining security through pre-validated access controls
2Productivity
If direct data exchange between network elements is enabled, then information obtaining efficiency is improved, but system complexity increases
Solution Approach 1:
The patent creates universal authentication and subscription verification mechanisms that can be implemented by any network element regardless of its specific function. These standardized multi-functional procedures allow direct data exchange across different network elements without requiring element-specific complex integration logic
Solution Approach 2:
The patent introduces standardized authentication and subscription verification procedures as intermediary mechanisms between network elements. These intermediary verification processes enable direct efficient data exchange while maintaining system manageability through standardized mediation protocols

AI summary
This disclosure relates to method and apparatus for obtaining data information. The method includes: obtaining a capability invocation subscription request transmitted by a second function network element based on subscription request parameter information, the subscription request parameter information being determined according to authentication response parameter information, the authentication response parameter information being obtained by a network exposure function device performing authentication processing on a capability invocation request, and the capability invocation request being transmitted by the second function network element based on a first subscription rule; obtaining access parameter information from the subscription request parameter information, and performing subscription verification on the capability invocation subscription request based on the access parameter information; and generating capability invocation subscription response information for the capability invocation subscription request, and transmitting the capability invocation subscription response information to the second function network element.
