The present invention discloses a method for selecting a system and transmitting data for a WLAN/mobile phone network interworking service in a WLAN and mobile phone network interworking system, which includes: a signal measuring step for setting up a service set ID list of a WLAN in an access point in order for a terminal to allow access, and measuring signal strength for the WLAN access; an access deciding step for selecting an access system based on the signal strength measured in the signal measuring step; a WLAN performing step for periodically measuring signal strength of a WLAN channel satisfying the access allowable service set ID list, and accessing the corresponding WLAN channel or a mobile phone network according to the existence or absence of the WLAN channel guaranteeing signal quality for the WLAN access, when the WLAN access is confirmed in the access deciding step; and a mobile phone network performing step for periodically measuring signal strength of the WLAN channel satisfying the access allowable service set ID list, and converting the mobile phone network access into the WLAN access according to sufficient signal strength for the access, when the mobile phone network access is confirmed in the access deciding step, thereby efficiently interworking services between the WLAN and the mobile phone network. As a result, the wireless internet service can be facilitated.
