ABSTRACT:
For the establishment of a call in a communications network (KN), one of two or more different subscriber identifications (UA) which all address the called subscriber (B) is sent from a terminal (T1) of a calling subscriber (A) to a service unit (SU) of the communications network (KN). The service unit (SU) accesses a database (DB) which manages different types of subscriber identifications (UA) and in which groups of two or more different subscriber identifications are assigned to one called subscriber (B) each. Via the database access, the service unit (SU) determines from the received subscriber identification (UA) a network address (RN) assigned to the called subscriber (B) which addresses a terminal (T2) of the called subscriber (B) in the communications network (KN). The call between the calling subscriber (A) and the called subscriber (B) is then established by means of the network address (RN).
