UE Policy Reporting for Reliable 5G and 6G Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack effective methods for verifying the application of UE policies by user equipment, leading to potential conflicts and misapplications of policies intended by the network.
Innovation Solution
A network entity, such as a UE-PCF, includes a transceiver and processor to manage UE policies through policy control report triggers (PCRT) and policy enforcement reports, ensuring network entities are notified of UE policy enforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If UE policies are enforced without verification mechanism, then policy application speed is improved, but policy reliability deteriorates due to potential conflicts and misapplications
Solution Approach 1:
The patent implements a feedback mechanism where the UE sends policy enforcement reports to the network entity (UE-PCF). The report includes information about whether the UE can apply the received policies, allowing the network to verify policy enforcement status and take corrective actions if needed, thus resolving the contradiction between fast policy application and reliable enforcement
Solution Approach 2:
The patent introduces an intermediary verification mechanism through the policy enforcement report that mediates between the UE's policy application and the network's policy intent. This intermediary feedback allows the network to indirectly verify policy enforcement without interfering with the speed of policy application
2Reliability
If policy verification mechanism is implemented, then policy management reliability is improved, but system complexity increases due to additional signaling and processing
Solution Approach 1:
The patent extracts only the essential verification information needed for policy enforcement (whether the UE can apply the policy) and sends it back to the network. By taking out only the critical verification data rather than comprehensive monitoring, the system achieves reliable policy management with minimal additional complexity
Solution Approach 2:
The UE autonomously determines and reports its own policy enforcement capability without requiring complex external verification mechanisms. The self-service approach where the UE evaluates and reports its own status reduces the need for complex network-side verification infrastructure

AI summary
The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. According to an embodiment of the present disclosure, a first network entity for performing a user equipment-policy control function (UE-PCF) in a wireless communication system may comprise: a transceiver; and at least one processor for controlling the transceiver, wherein the at least one processor is configured to: receive a policy control creation request message from a second network entity for performing the UE-PCF, and transmit a policy control creation response message to the second network entity. According to a method and a device according to various embodiments of the present disclosure, it is possible to improve the reliability of UE policy management by using a policy control reporting initiator that allows a network entity to provide a notification upon receiving a UE policy enforcement report.
