receiving a set of URSP rules with traffic descriptors with criteria for matching the URSP rules to a packet sent by the UE;
every time a packet is prepared for transmission, validating the URSP rules by the UE before a match of the URSP rules is made to a protocol data unit (PDU) session;
verifying a content and signature of the URSP rules have not been altered;
