URSP Configuration via Location-Based Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in effectively configuring a user routing selection policy (URSP) for dynamically deployed application services, leading to unnecessary signaling overheads due to pre-configured policies for all users.
Innovation Solution
A service configuration method that involves an access management network element requesting a user routing selection policy (URSP) from a policy control network element only when a target terminal device is located in a specific target area, ensuring that the URSP is configured and used only when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If URSP is configured for all terminal devices in advance regardless of location, then service accessibility is improved, but signaling overhead increases
Solution Approach 1:
The patent applies local quality by configuring URSP policies differently based on terminal device location. Terminal devices in the target area receive URSP configurations enabling access to the application service, while devices outside the target area do not receive such configurations. This location-based differentiation resolves the contradiction by providing service accessibility only where needed (improving reliability locally) while avoiding unnecessary signaling to devices that cannot access the service (reducing overall signaling overhead).
2Reliability
If URSP is configured for all terminal devices in advance, then service availability is improved, but resource utilization deteriorates
Solution Approach 1:
The patent implements local quality by making URSP configuration availability dependent on the terminal device's location relative to the target area. Devices within the target area have service availability ensured through URSP configuration, while devices outside the area do not receive configurations. This resolves the contradiction by maintaining service availability for relevant users while improving resource utilization by avoiding wasteful configuration distribution to all users regardless of location.
3Loss of energy
If URSP is configured dynamically based on location, then signaling overhead is reduced, but service accessibility for mobile users deteriorates
Solution Approach 1:
The patent employs feedback mechanisms where the network monitors terminal device location and dynamically triggers URSP configuration based on whether the device enters or exits the target area. This location-based feedback resolves the contradiction by reducing signaling overhead through selective configuration (only when location conditions are met) while maintaining service accessibility for mobile users who enter the target area, as the system responds to their location changes with appropriate policy configurations.

AI summary
This application provides a service configuration method, a communication apparatus, and a communication system. An AF configures a service request to an AMF by using an NEF, so that the AMF may request URSP configuration from a PCF when target UE is located in a target area. In this way, the PCF can effectively configure a URSP in a scenario in which an application service is dynamically deployed.
