The invention provides conditions for extending a list of communication services and provides a user against anonymous or undesirable communication sessions. At the beginning, a message about the person of a called user is formed on the device of said user and is transmitted to a telephone network. The messages formed on the device of the called user are received in the telephone network, the message about the person of the called user and the telephone number of the called user are recorded in a database. Afterwards, a message about the person of the called user is formed on the device of a calling user, the message about the person of the calling user is formed and the thus formed messages are transmitted to the telephone network. The telephone number of a device, from which the messages have been received, is identified in the telephone network and the message about the person of the called user received from the device of a calling user is compared with the earlier received messages about the person of the called user. When the result of comparison is positive, the telephone number of the device of the called user is extracted from the database, a communication channel between the telephone network and the device of the called user is established, and a communication channel between the devices of the called and calling users are established, wherein the message about the person of the called user is formed on the device of the called user according to a specified data representation form, in the telephone network, upon the positive result of comparison of the message about the person of the called user received from the device of a calling user with the messages about the person of the called user received earlier from the devices of the called users, firstly the data representation form in the message about the person of the called user is compared with the data representation form in the message about the person of the calling user, and in the case of coincidence of the data representation forms in the respective messages, the telephone number of the device of the called user is extracted from the data base and a communication channel between the devices of the called and calling users is established. |
