Abstract: A method is provided for supporting state mode transition by an entity of a cellular network in case that a plurality of networks interwork. When a value of interference caused by a neighbor entity of a wireless local area network (WLAN) is equal to or larger than a predefined threshold value, a first message instructing another entity of the WLAN to perform a mode transition from an active mode to an idle mode is transmitted to another entity of the WLAN. In response, a second message including information indicating whether status of the mode transition of the another entity of the WLAN is successful is received from the another entity of the WLAN. When the information indicates that the status of the mode transition of the another entity of the WLAN is successful, status information of the another entity of the WLAN is updated based on the second message.

Abstract: A method and apparatus for acquiring information on an access point (AP) in a wireless communication system is provided. An AP information management entity of a cellular system transmits a request for information on an AP, which is located within coverage of an eNodeB (eNB), to an AP server which is located outside of the cellular system, and receives a response, which includes a result code of the request, from the AP server. The AP information management entity is one of an eNB, mobility management entity (MME), or a new entity of the cellular system.
