Abstract
An integrated WLAN/WWAN Radio Access Technology (RAT) architecture is described in which signaling used to control the integration of the WLAN/WWAN architecture is performed over the Radio Resource Control (RRC) plane. The integrated architecture may allow for User Equipment (UE) assistance in cell selection and traffic steering. In particular, UE-assisted RRC signaling is described for managing inter-RAT session transfers and secondary cell (SCell) selection.
