Abstract: A wireless LAN connection method using signal strength is provided. The wireless LAN connection method is carried out by an access point, and includes the steps of: measuring wireless signal strength of a signal which is received from a terminal having transmitted a connection request; determining whether the wireless signal strength is equal to or greater than a predetermined threshold; checking whether the terminal is registered in an available list which is information on terminals having had signal strength equal to or greater than the predetermined threshold when the wireless signal strength is less than the predetermined threshold; and permitting connection of the terminal to a wireless LAN only when the terminal is registered in the available list.

Abstract: Disclosed is a method for controlling an outgoing call. The method for controlling an outgoing call in a mobile phone according to one aspect of the present invention comprises: a step of analyzing an audio signal input from an external source through a microphone for a predetermined time in accordance with preset criteria when an outgoing call gets connected; and a step of determining whether the outgoing call is normal or abnormal based on the result of the audio signal analysis. The method for controlling an outgoing call according to the present invention may disconnect a call in a short time when an outgoing call is unintentionally or erroneously conducted, to thereby prevent a wasted call charge, and may deliver a message indicating such an erroneous call to a caller so that the caller may recognize the erroneous call, to thereby minimize inconvenience of the caller.
