Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present invention provides a method for controlling Wireless Local Area Network (WLAN) aggregation and an associated equipment. The method comprises the following steps of: acquiring, by a first radio access network node, WLAN information about a User Equipment (UE); and, controlling, by the first radio access network node, WLAN aggregation for the UE according to the acquired WLAN information. A second radio access network node decides whether to maintain a WT and/or whether to establish WLAN aggregation for the UE when the UE moves to a first radio access network; and, the second radio access network node transmits information about whether to maintain the WT and/or indication information about whether to establish the WLAN aggregation for the UE. The WT receives UE context reference information transmitted by the first radio access network node; and, the WT indexes a UE context according to the received UE context reference information. With the present invention, the WLAN aggregation performance in a UE mobility scenario can be improved.
