    Abstract: A method for computing maximum traffic capacitance of a base station using a virtual call in the digital mobile communication system in such a way that an operator at operating terminal for Base Station Manager (BSM) inputs call-set-request instructions using the virtual call to maintain and repair the digital mobile communication system so that traffic state is set between mobile stations in the service area of test base station and a vocoder of a Base Station Controller (BSC) to compute maximum traffic capacitance of the test base station. An operator at operation terminal inputs call set information by operator instruction as much as mobile station numbers to be tested to compute maximum traffic capacitance of the base station. The BSM inputs a virtual call-set-request-instruction by means of a virtual call-set-start-flag. A virtual call-set-path is given among the vocoder of the BSC, the channel element, and the mobile station without going through Mobile Switching Center (MSC) that processes call setting and switching of a traffic path.

    Abstract: In a method of driving a nonvolatile memory device a first data state is determined from among the plurality of data states. The number of simultaneously programmed bits is set according to the determined first data state and a scanning operation is performed on data input from an external device to search data bits to be programmed. The searched data bits are programmed in response to the number of simultaneously programmed bits. The number of simultaneously programmed bits corresponding to the first data state is different from a number of simultaneously programmed bits corresponding to at least a second of the plurality of data states.
