URSP Rule Determination via Shared Service Parameter Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in managing service parameters for multiple user equipment (UEs), leading to redundant transmissions and increased resource utilization.
Innovation Solution
A method where a V-PCF transmits a service parameter to an H-PCF only once for multiple UEs when the parameter is applicable, optimizing communication by reducing redundant transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the V-PCF transmits the service parameter to the H-PCF for each UE individually, then each UE receives the parameter reliably, but redundant transmissions increase network load and reduce resource efficiency
Solution Approach 1:
The patent merges the transmission of identical service parameters for multiple UEs into a single transmission from V-PCF to H-PCF. The H-PCF then distributes this parameter to all affected UEs, combining what would otherwise be multiple separate transmissions into one, thereby reducing network load while maintaining delivery reliability.
Solution Approach 2:
The service parameter transmission mechanism is designed to serve multiple UEs simultaneously through a single transmission. The H-PCF acts as a universal distributor that can forward the same parameter to any number of UEs that match the service criteria, making the transmission system multi-functional rather than dedicated to individual UEs.
2Adaptability or versatility
If the V-PCF transmits the service parameter multiple times for different UEs, then all UEs receive the parameter, but the number of transmissions increases system complexity and reduces productivity
Solution Approach 1:
The V-PCF performs a preliminary check to determine whether multiple UEs require the same service parameter before transmission. When multiple UEs are identified as needing the same parameter, the V-PCF prepares a single transmission that will serve all of them, avoiding multiple separate transmissions and improving overall system productivity.
Solution Approach 2:
Instead of creating and transmitting separate parameter instances for each UE, the system creates one parameter transmission that is copied and distributed to multiple UEs by the H-PCF. This copying approach maintains service coverage for all UEs while significantly reducing the number of original transmissions required from the V-PCF.

AI summary
One disclosure of the present specification provides a method by which a target V-SMF performs communication. The method comprises the steps of: establishing a first UE policy association with an H-PCF for a first UE; establishing a second UE policy association with the H-PCF for a second UE; receiving a service parameter from a V-UDR; selecting either the first UE policy association or the second UE policy association on the basis of the service parameter being applicable to the first UE and the second UE; and transmitting, to the H-PCF, through the selected one UE policy association, a policy message including the service parameter for the first UE and the second UE, wherein the first UE is different from the second UE, and the first UE and the second UE can be a UE subscribing to an HPLMN including the H-PCF.
