Abstract: The invention concerns a method of establishing a connection via a communications network to a called terminal (TE) which is geographically located in the area (AREA) of two or more local line networks (LNA to LNC), as well as an exchange and a service control point for carrying out this establishment of a connection. A calling terminal requests a connection to the called terminal (TE) by means of a call request (CALL(N)) which is provided with a called number (N) assigned to the called terminal (TE). To establish the connection, that of the two or more local line networks (LNA to LNC) via which the called terminal (TE) can be reached, is determined by means of a learning procedure using the called number (N).

Abstract: To set up a telecommunication link to a person who is in a substantially enclosed facility such as an airplane, inside which there are several internal communication transmitting terminals operated by a private branch exchange of the facility, a personal call number is assigned to a private telecommunication transmitting terminal of the person in a public telecommunication network at least during the person's stay in the facility, the assignment is stored of his/her personal call number to the internal communication transmitting terminal assigned to the person during his/her stay in the facility. A call directed to the personal call number of the person is rerouted together with the personal call number or a corresponding ID to the private branch exchange.

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).
