Abstract: PURPOSE: A method for implementing a UIM_CMDB(command handling window) of a BSM(Base Station Manager) of a PCS is provided to display a necessary parameter only, without displaying every parameter at a time, when an operator selects the necessary parameter. CONSTITUTION: A UIM_CMDB constitutes each command as linked list types with a predetermined data structure. The UIM_CMDB implements a command selection screen composed of input buttons corresponding to each command name. If an event is generated, the UIM_CMDB retrieves a structure including information on a corresponding command, through a command number. The UIM_CMDB displays parameters only which are not option parameters, on a parameter form screen among linked list-typed parameters. If the option parameters exist, the UIM_CMDB freely displays grouped parameters according to a selection parameter kind. If a command relating to the displayed parameters is performed, the UIM_CMDB transmits a command relating to the displayed parameters and inputted parameter values to a COHB(Command Output Handling Block). The COHB reopens a corresponding command data file only relating to the command, and checks whether the command is correctly inputted. The COHB transmits the command to an application block. The application block performs the command to transmit a result to the COHB, and transmits the result to the UIM_CMDB. The UIM_CMDB outputs the result on a processing window screen.
