an improved method of updating parameters stored in memory of mobile telecommunications stations . an object model represents all the parameters that can be modified in an is - 683a mobile station . the details of the physical location of each parameter are defined in this mobile object model . advantageously , when any parameter is changed or added , it is necessary to provide the computer system , which generates messages to be transmitted to the mobile station , only the identification and value of the parameter to be added or changed . the computer system then generates a message sequence that defines the memory location in the mobile station to be changed , and the new value of the data for that memory location . advantageously , this arrangement sharply reduces the total number of airwave messages transmitted to the mobile station in order to change or add a parameter .
