1. A method for modifying the operating mode of a technical communications group platform (TCGPL) of a telecommunications network (TC network) for at least one driving object 1 which is controlled by a subscriber object (SUBC) by modifying, by means of at least one modifying object 2 , the operating mode of at least one object 3 to be modified or which has been modified, whereby all considered objects of categories 1/2/3, i.e. driving/modifying/to be modified/modified, belong to the TCGPL and are executable but only need to exist as an instance of a considered object—and this applies also for the considered TCGPL—when they are used in an application of the TCGPL and/or this modification process, with the steps: I. Identifying and/or defining in the TCGPL, whereby this can include its extension: Of these three not necessarily different objects of the categories 1/2/3, whereby the driving object 1 determines the modification which produces from the object 3 to be modified the modified object 3 in an automated way, and This determination by object 1 which is the specification for the step II. derivation of the modifying object 2 in a representation executable by the TCGPL, contains a. A time at which and/or from which b. The modified object 3 in future undergoes/carries out which modification of the execution effect in relation to the execution effect of the object 3 to be modified, whereby, moreover, the operating mode of the TC network and the TCGPL is unmodified insofar as the latter is not modified by this TCGPL modification determined by object 1 and related to object 3 , and c. The TCGPL can derive in an automated way the executability both of the identified/defined modifying object 2 and also of its object 3 modified by its execution. II. Automated derivation by the TCGPL according to I.c. of such a representation executable by it for the modifying object 2 identified/defined according to I. a./b. and execution of its modification on the object 3 to be modified. III. Substitution by the TCGPL of the object 3 to be modified in the TGCPL by the object 3 modified according to II.—the automated derivation of its executable representation by the TCGPL, according to I.c., can take place before or after this substitution—whereby all in all the modification according to the method in the operating mode of the considered TCGL is effected.
