Abstract: A method and apparatus for routing data in a wireless communication system is provided. In trusted non-3rd generation partnership project (3GPP) access, a wireless local area network (WLAN) access gateway receives parameters, which includes 3GPP core network load information and a core network routing rule, from an entity of a 3GPP system, and routes received UL data based on the received parameters through at least one of the 3GPP system and a non-3GPP system. In un-trusted non-3GPP access, an evolved packet data gateway (ePDG) receives parameters, which includes 3GPP core network load information and a core network routing rule, from an entity of a 3GPP system, and routes received UL data based on the received parameters through at least one of the 3GPP system and a non-3GPP system.
