URSP Rule Identifier Feedback for PDU Session Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing UE policy information for PDU session establishment and compliance with URSP rules, particularly in scenarios where terminals do not establish matching PDU sessions for application traffic transmission, leading to potential non-compliance and network recognition issues.
Innovation Solution
A method and device for generating a URSP rule identifier based on received UE policy information, allowing terminals to configure PDU session establishment messages and transmit URSP information to the network, including identifiers and codes to ensure compliance with URSP rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminals do not establish matching PDU sessions for application traffic transmission, then network resource utilization is improved, but URSP rule compliance cannot be verified leading to potential non-compliance issues
Solution Approach 1:
The terminal feeds back URSP information including the generated URSP rule identifier to the network. This feedback mechanism allows the network to verify whether the terminal has correctly applied URSP rules for PDU session establishment, resolving the compliance verification issue while maintaining resource utilization efficiency
Solution Approach 2:
The terminal generates a URSP rule identifier based on received UE policy information before establishing PDU sessions. This preliminary action ensures that the terminal has a identifiable reference for the applied URSP rule, enabling subsequent compliance verification by the network
2Reliability
If URSP rule identifiers are generated and transmitted to the network, then URSP rule compliance verification is improved, but signaling overhead and device complexity increase
Solution Approach 1:
The terminal autonomously generates the URSP rule identifier based on received UE policy information without requiring complex network intervention. This self-service approach minimizes network signaling overhead while ensuring compliance verification capability, as the terminal independently creates the identifier that reflects its applied URSP rule

AI summary
A method of operating a terminal in a wireless communication system may comprise receiving UE policy information from a network, generating at least one UE route selection policy (URSP) rule identifier based on the UE policy information received from the network, the terminal applying a first URSP rule to a protocol data unit (PDU) session, and transmitting first URSP information to the network based on the first URSP rule applied to the PDU session. The first URSP information may include the first URSP rule identifier related to the first URSP rule applied to the PDU session and a first UE policy section code (UPSC).
