         4 . The method according to  claim 1 , wherein step A) to step F) are preceded registering the mobile unit at the machine control unit of the ground milling machine. 
     
     
         5 . The method according to  claim 1 , further comprising operating the machine control unit such that the ground milling machine exclusively considers the at least one suggested value from the mobile unit to an exclusion of another mobile unit. 
     
     
         6 . The method according to  claim 1 , wherein the acceptance and/or rejection in step E) is performed by a one-step confirmation function. 
     
     
         7 . The method according to  claim 1 , wherein an unrestricted adjustment range is provided with respect to the at least one dosing parameter and/or the at least one process parameter set in step A), within which range the at least one suggested value that has been entered at the mobile unit and transmitted in step B) and step C) is implemented directly by the machine control unit, and the implementation of step D) to step F) is only required if the at least one suggested value is outside the unrestricted adjustment range. 
     
     
         8 . The method according to  claim 1 , wherein documentation of at least one of the at least one driving parameter, the at least one dosing parameter or the at least one process parameter is created during the milling operation and stored on the ground milling machine. 
     
     
         9 . The method according to  claim 1 , wherein a protective field function is provided such that a warning signal is triggered when the mobile unit is located within a defined and monitored safety range.
