WIPO Patent Application WO/2023/182721

Kind Code:

A1

Abstract:

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method for re-evaluating one or more user equipment route selection policy (URSP) rules associated with a user equipment (UE) in communication with a network entity is disclosed. The method comprises receiving, at a user equipment non-access stratum (UE NAS) layer, a back-off timer from the network entity. The back-off timer is related to non-initiation of a packet data unit (PDU) session associated with an application within the UE. The method comprises initiating, by the UE, the PDU session associated with the application. The method comprises indicating, by the UE NAS layer, an expiry of the back-off timer. The method comprises, upon the expiry of the back-off timer, re-evaluating, by the UE, the one or more URSP rules to determine whether a change of association of the PDU session with the application is required.
