1. A method, comprising:
establishing a protocol data unit (PDU) session by a user equipment (UE) in a mobile communication network;
receiving a PDU session modification command message from the network, wherein the command message carries a Quality of Service (QoS) rule for performing a QoS operation associated with the PDU session;
determining whether the command message causes a syntactical error in the QoS operation; and
rejecting the PDU session modification command message upon determining the syntactical error occurs when the QoS operation is a categorized operation as well as the QoS operation meets one of the following situations: an empty packet filter list is in the QoS rule, a non-empty packet filter list is in the QoS rule, and a packet filter to be deleted does not exist in the existing QoS rule, wherein the UE rejects the PDU session modification command message with a 5G session management (5GSM) cause value indicating the syntactical error in the QoS operation.
