Wireless UE Policy Feedback for Dynamic PCF Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 3GPP architecture lacks a feedback mechanism for User Equipment (UE) policies, preventing the Policy Control Function (PCF) from reconfiguring UE policies as needed to improve UE-related services and network efficiency.
Innovation Solution
A method and system that enables UE to send feedback messages to the PCF regarding the status of UE policies, including successful or failed execution, storage, and location information, allowing the PCF to modify, delete, or recreate the policies accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the PCF provides UE policy to the UE without feedback mechanism, then the system architecture remains simple, but the PCF cannot re-configure UE policy to improve UE-related services
Solution Approach 1:
The patent introduces a feedback mechanism where the UE sends status information about UE policy execution to the PCF. This feedback enables the PCF to re-configure UE policies based on actual execution status, resolving the contradiction by adding adaptability through a relatively simple feedback channel rather than complex re-architecture.
2Reliability
If the PCF implements feedback mechanism for UE policy status, then the PCF can improve UE-related services, but the signaling overhead between UE and PCF increases
Solution Approach 1:
The patent extracts only the essential status information needed for policy re-configuration from the complex UE policy execution process. By taking out only the critical feedback elements (execution status, storage status, location information), the system achieves reliable policy management with minimized signaling overhead.
3Measurement precision
If the UE sends detailed feedback message with all status information, then the PCF can make accurate policy decisions, but the message size and processing overhead increase
Solution Approach 1:
The patent applies local quality by including different levels of detail in feedback messages based on specific execution contexts. The feedback message structure allows selective inclusion of status information elements (successful execution, failed execution, storage information, location information) depending on what is locally relevant to the current policy execution state, achieving accurate decision-making without uniform processing overhead.

AI summary
A method for controlling a User Equipment (UE) policy by a UE is provided. A method includes receiving the UE policy from a Policy Control Function (PCF), performing a first action in response to receiving the UE policy from a successful execution of the received UE policy, a failed execution of the received UE policy, and storing of the received UE policy, and transmitting a feedback message to the PCF based on the first action.
