Abstract
A user terminal includes a controller that performs selection of an access network in which the user terminal exchanges traffic from among a cellular RAN (Radio Access Network) and a WLAN (Wireless Local Area Network). The controller stores a RAN rule for determining traffic steering to a WLAN having a RAN provided identifier (ID), receives a WLAN ID broadcasted from a cellular base station (BS), applies the WLAN ID to the RAN rule to determine whether to perform traffic steering, roaming from the RAN to another RAN, determines whether to acquire another WLAN ID provided by the other RAN based on a policy established by the RAN, receives the other WLAN ID from a second BS of the other RAN, and applies the other WLAN ID to the RAN rule to determine whether to perform traffic steering to the WLAN having the other WLAN ID, in the second cellular RAN.
