Abstract

An apparatus and system for updating a User Equipment (UE) Routing Policy (URSP) when the UE is in a Visited Public Land Mobile Network (VPLMN) are described. A policy control function (PCF) of the home PLMN sends to the UE a value generated by an authentication server function (AUSF) and a counter with updated URSP parameters. The UE verifies and applies the updated URSP parameters by generating a desired value and determining that the desired value matches the received value. The value is based on a counter associated with the UE-specific key and URSP data or application identification and authentication information.
