1. A method comprising: receiving, at a user equipment, while being served by a first system and during a protocol data unit (PDU) session modification procedure, a PDU SESSION MODIFICATION COMMAND message including an access point name aggregate maximum bit rate value of a second system; determining that there is an inter-system change from the first system to the second system; and in response to determining that there is an inter-system change from the first system to the second system, mapping, at the user equipment, the 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.
