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

A communication system for transmitting data to a first subscriber having a first primary service communication facility for communication via a primary communication service of a first network and a first secondary service communication facility for communication via a secondary communication service of a second network assigned thereto, the second network being different from the first network, the system comprising:

• a receive hardware device configured to receive primary and secondary address information assigned to the first primary service communication facility and the first secondary service communication facility, respectively, in connection signaling sent from the first primary service communication facility to a second primary service communication facility to attempt to establish a voice communication connection between the first primary service communication facility and the second primary service communication facility such that the secondary address information is receivable by the second primary service communication facility without access to data from an access or assignment table of an exchange, the first primary address information identifying the primary address information of the first primary service communication facility and the secondary address information identifying the secondary address information of the first secondary service communication facility;
• an identification hardware device configured to identify the primary and secondary address information in the connection signaling received by the receive unit;
• a storage control hardware device configured to store the primary and secondary address information identified by the identification hardware device in a call log or an address book;
• and
• a stored secondary address information transferring hardware device configured to transfer 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 to be sent from the second secondary communication service facility to the first secondary communication service facility via the transferred secondary address information;
• and
• wherein address information for the second primary service communication facility is usable for at least one of addressing and network path control for connection signaling between the first primary service communication facility and the second primary service communication facility.

A communication terminal for transmitting data to a first subscriber having a first primary service communication facility for communication via a primary communication service of a first network and a first secondary service communication facility for communication via a secondary communication service of a second network assigned thereto, the first network differing from the second network, the communication terminal comprising:

• a telephone receive hardware unit configured to receive connection signaling from the first primary service communication facility, the connection signaling configured to attempt to establish a voice communication connection, the connection signaling having primary address information assigned to the first primary service communication facility and secondary address information assigned to the first secondary service communication facility such that the secondary address information is receivable by the communication terminal without access to data from an access or assignment table of an exchange, the primary address information identifying primary address information of the first primary service facility and the secondary address information identifying the secondary address information of the first secondary service communication facility, wherein address information for a second primary service communication facility is usable for at least one of addressing and network path control for connection signaling between the first primary service communication facility and the second primary service communication facility;
• a telephone identification hardware unit configured to identify the primary and secondary address information in the connection signaling received by the telephone receive hardware unit;
• a telephone storage control hardware unit configured to store with mutual assignment the primary and secondary address information identified by the telephone identification hardware unit in a call log or an address book;
• and
• a telephone address transfer hardware unit configured to transfer the secondary address information stored by the telephone storage control hardware unit to a second secondary service communication facility that is configured to transmit the data from the secondary communication service to the first secondary service communication facility using the transferred secondary address information.

A second primary service communication facility for transmitting data to a first subscriber having a first primary service communication facility for communication via a primary communication service of a first network and a first secondary service communication facility for communication via a secondary communication service of a second network assigned thereto, the first network differing from the second network, the second primary service communication facility comprising:

• a receive hardware unit configured to receive primary and secondary address information assigned to the first primary service communication facility and the first secondary service communication facility, respectively, in connection signaling sent from the first primary service communication facility to the second primary service communication facility to establish a voice communication connection such that the secondary address information is receivable by the second primary service communication facility without access to data from an access or assignment table of an exchange the primary address information identifying the primary address information of the first primary service communication facility, the secondary address information identifying the secondary address information of the first secondary service communication facility;
• an identification hardware unit configured to identify the primary and secondary address information in the connection signaling received by the receive unit;
• a storage control hardware unit configured to store the primary and secondary address information identified by the identification hardware device in a call log or an address book;
• and
• a stored secondary address information transferring hardware device configured to transfer 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 be transmitted from the secondary communication service to the first secondary service communication facility using the transferred secondary address information;
• and
• wherein address information for a second primary service communication facility is usable for at least one of addressing and network path control for connection signaling between the first primary service communication facility and the second primary service communication facility.
