Abstract

PURPOSE: A method for locking a terminal using a call number and the terminal having a locking function using the call number are provided to enhance security of a mobile terminal by using a call number in locking the mobile phone. CONSTITUTION: When a user loses a mobile terminal or leaves it behind at a certain place, he/she calls the mobile terminal and transmits a call number(S301). The call number is inputted as an RF signal into an RF transmitting/receiving unit, the RF transmitting/receiving unit decodes the RF signal to output it to an extracting/comparing unit, and the extracting/comparing unit extracts the call number(S302). The extracting/comparing unit determines whether the call number is identical to a pre-set password(S303). If the call number is identical to the pre-set password, the extracting/comparing unit outputs a lock setting signal to an MSM(Mobile Station Modem) and the MSM calls a locking routine and sets a locking function for the mobile terminal(S304).
