A method for configuring terminal devices is provided. The method includes sending a first message containing parameter values to a first terminal. The first terminal includes a data structure containing designations for each parameter value. The method includes storing, in response to receiving the first message, the parameter values in associated elements of the data structure. The method includes reading the data structure. The method includes determining the associated elements by determining the associated designations of the associated elements; or, comparing the data structure and an initial data structure before sending the first message. The first terminal contains the initial data structure. The method includes generating a second message including instructions for storing a parameter value in a second terminal. The instructions are generated as a result of evaluating the data structure. The instructions include the determined associated designations. The method includes sending the second message to the second terminal.
