1. An apparatus comprising:
one or more processors; and
a memory coupled to the one or more processors and configured to store instructions that, when executed by the one or more processors, cause the apparatus to:
receive a first message indicating an establishment of a first evolved packet system (EPS) bearer or a modification of the first EPS bearer in a first communications system, wherein the first message comprises a quality of service (QOS) rule for a second communications system and a session aggregation maximum bit rate (AMBR) for the second communications system, wherein the QoS rule and the session AMBR correspond to the first EPS bearer, and wherein the first EPS bearer is a default bearer;
store the QoS rule and the session AMBR;
move from the first communications system to the second communications system; and
determine, based on the session AMBR, a session AMBR used in the second communications system, and communicate with the second communications system by using the QOS rule.
