A method for the at least partially automatic determination of contact information of at least one communication partner in the context of a communication connection between at least two communication partners in a communication network is proposed, wherein at least one contact information of the communication partner initiating the communication connection is communicated to the at least one receiving communication partner. The at least one contact information is predetermined by the communication partner initiating the communication connection. Furthermore, a terminal for the use in a communication network is provided, preferably a mobile network according to a GSM, GPRS and/or UMTS radio network standard, which terminal is designed and/or adapted to at least partially carry out the method. Furthermore, a network node in a communication network is provided, preferably a mobile network according to a GSM, GPRS and/or UMTS radio network standard, which node at least contributes to the establishment, the holding and/or the disconnection of the communication connection.
