Solution Overview

Problem

Current 5G systems support static user consent handling, which is inadequate for real-time applications and user data exposure control, potentially impacting user privacy and application experience.

Innovation Solution

Implementing methods and apparatuses that enable secure user consent data notification, allowing user equipment (UE) to provide, update, and revoke user consent data in real-time through a common application programming interface (API) framework or core network function, using a key derived from the CAPIF security context.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If static user consent data is stored as part of subscription data, then the system is simple to implement, but it cannot support real-time user consent updates and dynamic data exposure control

Engineering Contradiction:
Improvereal-time consent update capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transforms static consent data into dynamic, real-time updatable consent information. The CAPIF framework enables consent data to be modified dynamically by network functions, allowing users to update their consent preferences in real-time without requiring system reconfiguration, thus achieving adaptability while maintaining manageable complexity through standardized procedures

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces a CAPIF (Common API Framework) as an intermediary layer between the user equipment and the network functions. This framework mediates consent data management, providing a standardized interface for real-time consent updates while abstracting the complexity from both the user equipment and core network functions, enabling real-time adaptability without proportionally increasing overall system complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If general consent data is used for all services, then the implementation is straightforward, but it cannot provide service-specific consent control and impacts user privacy

Engineering Contradiction:
Improveservice-specific consent controlVSAvoiddata management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments consent data into service-specific units within the CAPIF framework. Each service or network function can access and manage its own specific consent data independently, allowing granular control over what data is shared with which service. This segmentation enables service-specific consent control while keeping data management organized and manageable through the standardized CAPIF interface

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by allowing different consent data to be associated with different services, network functions, or data exposure scenarios. Each service receives only the consent data relevant to its specific function, enabling precise control over data exposure for each service while maintaining overall system coherence through the CAPIF framework's standardized management procedures

Inventive Principle:
Principle #3Local quality

3Productivity

If user consent data is exposed to application servers, then application functionality is enhanced, but user privacy and data security are compromised

Engineering Contradiction:
Improveapplication service capabilityVSAvoiddata security
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The CAPIF framework acts as a secure intermediary between user equipment and application servers. It validates and controls the exposure of user consent data, ensuring that only authorized services receive appropriate consent information. This intermediary layer enhances application functionality by enabling controlled data sharing while simultaneously protecting user privacy through standardized security procedures and authorization mechanisms

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements feedback mechanisms where the CAPIF framework continuously monitors and controls data exposure based on current consent status. When user consent changes, the framework provides feedback to relevant network functions and application servers to update their access permissions accordingly. This feedback loop ensures that application services operate with current, authorized consent data while maintaining ongoing security validation

Inventive Principle:
Principle #23Feedback

AI summary

Various aspects of the present disclosure relate to a user equipment (UE) that transmits information, such as to a common application programming interface framework (CAPIF) function or to a core network function (CNF), to trigger a user consent provisioning procedure. The UE also transmits a data exposure notification comprising at least user consent data, and the UE receives a data exposure response acknowledgement (ACK) that indicates the user consent data is stored for reference of the user consent.
