A method, base station, and device perform an offload from a cellular RAN to a wireless LAN via a network selection operation to select an access network with which user terminal traffic is exchanged from the cellular RAN and the wireless LAN on the basis of parameters transmitted from a first base station to the user terminal. The parameters comprise at least one of a cellular signal strength threshold, a WLAN signal strength threshold, and a WLAN load threshold. After transmitting the parameters, the transmitted parameters are transferred from the first cellular base station to a second cellular base station, in response to the user terminal performing a handover from the first cellular base station to the second cellular base station. The transferred parameters enable the second cellular base station to determine whether there is a need for a change of configuration indicated by the transferred parameters.
