Abstract
In a wireless network discovery method according to an exemplary embodiment of the present invention, a) a propagation environment information message generated by using signal information received from the heterogeneous wireless networks is transmitted to the common core network, b) a wireless network discovery range generated by using the propagation environment information message is received from the common core network, c) it is determined if signal information received from a serving wireless network at a current location corresponds to the wireless network discovery range, and d) when the signal information corresponds to the wireless network discovery range in c), a network within the wireless network discovery range is discovered, when the signal information does not correspond to the wireless network discovery range in c), c) is periodically performed.
