Abstract
A method and apparatus for performing traffic steering in a wireless communication system is provided. A user equipment (UE) may be configured with a primary cell (PCell) and at least one secondary cell (SCell) by carrier aggregation. Or, the UE may be configured with a PCell of a master evolved NodeB (MeNB) and a primary SCell (PSCell) of a secondary eNB (SeNB) by dual connectivity. For one embodiment, the UE receives radio access network (RAN) assistance information on the PCell, and evaluates conditions for traffic steering only on the PCell based on the received RAN assistance information. For another embodiment, the UE receives RAN assistance information for each of a plurality of serving cells, and performs traffic steering between one serving cell, among the plurality of serving cells, and a wireless local area network (WLAN).
