Claim 17:
18. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to perform at least:
in an instance in which the apparatus receives an indication to remove Quality of Service (QoS) parameters associated with a QoS flow, while being served by a first system and during a protocol data unit (PDU) session modification procedure, removing, at the apparatus, an access point name aggregate maximum bit rate value associated with the QoS flow;
receiving, while being served by the first system and during the PDU session modification procedure, a PDU SESSION MODIFICATION COMMAND message including a new access point name aggregate maximum bit rate value of a second system; and
in an instance in which there is an inter-system change from the first system to the second system, mapping the new access point name aggregate maximum bit rate value of the second system received while being served by the first system to an access point name aggregate maximum bit rate value of a session management context for the second system, wherein the session management context for the second system is a default Evolved Packet System (EPS) bearer context.
