METHOD FOR CARRYING OUT A PRIVATE COMMUNICATION SESSION BETWEEN A USER OF A DATA TRANSMISSION NETWORK AND A TELEPHONE NETWORK USER

摘要

The invention enables a user to organise a private address space and protects against unauthorised communication sessions during a communication session between heterogeneous communications networks. At the beginning, one or more messages about the person of a called user are formed on the device of the called telephone network user and are transmitted to the telephone network. In the telephone network, the telephone number of the device of the called user is identified, messages are converted into a form suitable for transmission via data transmission networks and are transmitted to a data transmission network. One or more messages about the person of the called user and the telephone number of the device of the called user are recorded in an intermediate device of the data transmission network. Then, a message about the person of the called user is formed on the device of a calling user of the data transmission network and is transmitted to the data transmission network. In the intermediate device of the data transmission network, the address of the device of the calling user is identified, the received and recorded messages about the person of the called user are compared, the telephone number of the device of the telephone network called user is identified on the basis of the comparison, communication with the telephone network is established by forming the telephone number of the device of the called user, a message about the beginning of a communication session is formed and is transmitted to the address of the device of the calling user of the data transmission network. During the communication session, the signals from the device of the called user are received on the intermediate device of the data transmission network, are converted into a form suitable for transmission via data transmission networks and are transmitted to the address of the device of the calling user, the data packets of the communication session are received from the device of the calling user, are converted into a form suitable for transmission via the communication channel of the telephone network and are transmitted to a channel for communicating with the device of the called user.
