CAPIF Core Function API Registration Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual establishment of a trust domain between the Common Application Programming Interface Frameworks (CAPIF) core function and third-party API provider domains in 5G communication systems is cumbersome and requires an automated solution for efficient API registration and management.
Innovation Solution
A method and apparatus for registering API provider domain functions on a CAPIF core function entity, involving the receipt and validation of registration requests, generation of configuration information, and sending of response messages to manage secure API invocations, enabling automated registration and update of API provider domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual establishment of trust domain is used between CAPIF core function and third-party API provider domains, then security validation can be performed, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent implements preliminary action by pre-configuring trust relationships between CAPIF core functions and third-party API provider domains before actual API registration occurs. The AMF entity is pre-authorised to register multiple API provider domain function entities through a single trust establishment process, eliminating the need for repeated manual security validations during each registration operation.
2Reliability
If individual registration of each API provider domain function entity is performed manually, then security can be ensured, but the registration process becomes complex and resource-intensive
Solution Approach 1:
The patent applies merging by combining multiple individual registration operations into a single bulk registration process. The AMF entity can register a list of API provider domain function entities simultaneously through one authorised transaction, reducing process complexity while maintaining security through the pre-established trust domain. The CAPIF core function processes multiple registrations in one operation rather than requiring separate manual validations for each entity.
Solution Approach 2:
The patent implements universality by creating a generalised trust domain establishment mechanism that works for multiple API provider domain function entities simultaneously. The single trust domain configuration enables the AMF entity to perform multiple registration operations across different API provider domains through a unified process, rather than requiring separate specialised procedures for each entity.
3Productivity
If automated registration solution is implemented for multiple API provider domains, then efficiency is improved, but security validation becomes more challenging
Solution Approach 1:
The patent resolves this contradiction by performing security validation in advance through preliminary trust domain establishment. The CAPIF core function and AMF entity establish security credentials and trust relationships before the automated bulk registration process begins. This preliminary security configuration enables subsequent automated registrations to proceed efficiently without compromising validation reliability, as the security framework is already in place.
