A location information service supply system through interworking between a WLAN(Wireless Local Area Network) and a mobile communication network and a method thereof are provided to enable a location server accessing a 3GPP(3rd Generation Partnership Project) network to supply location information of a WLAN terminal to an external client, through communication between entities for interworking between the location server and the 3GPP network when receiving a request for tracking the location information of the WLAN terminal from the external client. A location tracking request of a WLAN terminal(10) is received from a client(40)(S21-S26). Routing information of a serving node where the WLAN terminal(10) is included is acquired, and it is checked whether the WLAN terminal(10) supports an SUPL(Secure User Plane Location)(S27-S29). If so, routing information on the WLAN terminal(10) is acquired from the serving node, and an SUPL procedure with the WLAN terminal(10) is carried out(S30,S31).
