PURPOSE: A method for upgrading the software of a mobile station automatically is provided to upgrade the software of a mobile communication terminal through the base station automatically. CONSTITUTION: A base station requests the software version information of a mobile station to the mobile station(101). The mobile station, in response to the request from the base station, outputs his software version information(103). The base station checks whether the version information of the mobile station accords with the current software version information of the base station(20). If it doesn't accord with the current version, the base station transmits the software data comprising new software version information to the mobile station(105). After carrying out upgrading to the new software version, the mobile station transmits the upgrade success signal to the base station(107).
