One or more services which are established in a first tele- and/or data communications system can be adapted and transferred to a second tele- and/or data communications system. Respective service is constructed by means of part functions in the service executing units or modules which are connectable between themselves. The part functions comprise first operator specific functions and connection specific functions, which last mentioned functions in this case are separated. The operator specific functions are placed into or executed by means of a device (16). The connection specific functions are placed in or executed by means of an interface (3, 4). The interfaces are unique for respective system (1, 2) and at the transfer of the service offer from one system to the other the interfaces (3, 4) are exchanged. |
