1. A method for a network node of a 3GPP radio access network (RAN), the method comprising:
determining a configuration that enables a user equipment (UE) to steer the UE's traffic between the 3GPP RAN and a wireless local area network (WLAN) without receiving a traffic steering command from the 3GPP RAN, the configuration comprising:
a forward traffic steering configuration comprising a first plurality of thresholds and/or conditions for which the UE, when connected to the 3GPP RAN, can initiate steering at least some of the UE's traffic from the 3GPP RAN to the WLAN; and
a backward traffic steering configuration comprising a second plurality of thresholds and/or conditions for which the UE, when connected to the WLAN, can initiate steering at least some of the UE's traffic from the WLAN to the 3GPP RAN,
wherein the backward traffic steering configuration includes one or more thresholds and/or conditions that are based on different values of a same parameter as one or more thresholds and/or conditions of the forward traffic steering configuration; and
sending the configuration to the UE in a single message.
