Abstract
An apparatus and method for locking a mobile terminal using a short message are provided to prevent the use of a mobile communication service and reduce a load of a system by preventing a function of a radio part of a mobile terminal. An MSC(Mobile Switching Center) of a GSM(Global System for Mobile communication) type mobile communication system registers a location of a mobile terminal and receives various operation information included in SIM(Subscriber Identity Module) information from the mobile terminal(S100). The MSC receives the SIM information, analyzes the information, and then checks whether the SIM information is SIM information of a mobile terminal which had been subscribed and registered for its host station(S110). If the SIM information has been received from a mobile terminal which had not been registered, the MSC determines whether a PIN(Personal Identification Number) code allowing a roaming service is inputted(S120). When the PIN code is inputted, the MSC searches a corresponding database and checks whether the PIN code has been classified as a limitation target SIM information for which a mobile communication service is not allowed(S130). If the PIN code corresponds to the mobile communication service limitation target, the MSC creates lock information for not allowing the mobile communication service as a short message, processes it to be recorded/stored in a designated 6F3C region of a SIM card, and then transmits it to the corresponding mobile terminal(S140). The MSC proceeds with communication according to the mobile communication service(S150).
