Method, communication system and communication terminal for the transmission of data

A communication system for transmitting data to a first subscriber, comprising:

• a first primary service communication facility assigning hardware device that assigns to the first subscriber a first primary service communication facility for communication via a primary communication service and a first secondary communication facility for communication via a secondary communication service;
• a primary address information assigning hardware device that assigns primary address information to the first primary service communication facility and assigns secondary address information to the first secondary service communication facility,
• wherein in the context of a connection signaling via the primary communication service from the first primary service communication facility to a second primary service communication facility,
• the primary address information and the secondary address information are transmitted via the primary communication service during the connection signaling from the first primary service communication facility to the second primary service communication facility via the primary communication service, and
• the second primary service communication facility identifies the transmitted primary and secondary address information and stores them in a call log with mutual assignment;
• a stored secondary address information transferring hardware device that transfers the stored secondary address information from the second primary service communication facility to a second secondary service communication facility for a transmission of data to the first subscriber;
• and
• a data transmission hardware device that transmits the data to be transmitted to the first subscriber via the secondary communication service to the first secondary service communication facility using the transferred secondary address information;
• and
• wherein address information for the second primary service communication facility is used for at least one of addressing and network path control for the connection signaling from the first primary service communication facility to the second primary service communication facility, and
• wherein the second primary service communication service receives the secondary address information without access to an assignment table of an exchange that identifies at least one of the primary address information of the first primary service communication facility and the secondary address information of the first secondary service communication facility.

A communication terminal for transmitting data to a first subscriber, where a first primary service communication facility for communication by way of a primary communication service and a first secondary communication facility for communication by way of a secondary communication service are assigned to the first subscriber and primary address information is assigned to the first primary service communication facility and secondary address information is assigned to the first secondary service communication facility, comprising:

• a telephone receive hardware unit that receives a connection signal from the first primary service communication facility with the primary address information and the secondary address information being transmitted in the context of the connection signaling via the primary communication service during the connection signaling from the first primary service communication facility to the second primary service communication facility via the primary communication service;
• a telephone identification hardware unit to identify the primary and secondary address information received by the receive unit;
• a telephone storage control hardware unit for the storage with mutual assignment of the primary and secondary address information identified by the identification unit in a call log;
• and
• a telephone address transfer hardware unit to transfer the secondary address information stored by the storage control unit to a second secondary service communication facility configured to transmit the data to be transmitted to the first subscriber via the secondary communication service to the first secondary service communication facility using the transferred secondary address information;
• and
• wherein address information for the second primary service communication facility is used for at least one of addressing and network path control for the connection signaling from the first primary service communication facility to the second primary service communication facility, and
• wherein the second primary service communication service receives the secondary address information without access to an assignment table of an exchange that identifies at least one of the primary address information of the first primary service communication facility and the secondary address information of the first secondary service communication facility.
