Classification: CPC H | IPC H

Claim 18:
19. 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:
receiving a first access point name aggregate maximum bit rate value while being served by a first system, the first access point name aggregate maximum bit rate value being associated with a quality of service (QoS) flow;
in an instance in which the QoS flow is deleted prior to an inter-system change from the first system to a second system, removing the first access point name aggregate maximum bit rate value;
in an instance in which the QoS flow is not deleted and the apparatus receives a PROTOCOL DATA UNIT (PDU) SESSION MODIFICATION COMMAND message including a second access point name aggregate maximum bit rate value of the second system, while being served by the first system, and during a PDU session modification procedure, storing the second access point name aggregate maximum bit rate value at the apparatus; and
in an instance in which there is an inter-system change from the first system to the second system, mapping the second 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.
