The invention enables a network user to organize the private address space and to be protected against unauthorized communication sessions. The inventive method consists firstly in forming one or more messages about the person of a called user on the device of said called user, sending said messages to the address of the intermediate device of a network, comparing, in the intermediate device, the message about the person of the user which is received from the calling user, with the earlier received messages and in determining, on the basis of the comparison results, the address of the device of the called user. Afterwards, a message announcing the beginning of the communication session is formed and is transmitted to the devices of the calling and called users. During the communication session, the inventive method also consists in receiving, in the intermediate device, data packets from the device of the calling user, substituting the address of the intermediate device for the address of the device of the called user and in transmitting the packets with modified address to the device of the called user, receiving the data packets from the device of the called user, substituting the address of the intermediate device for the address of the device of the calling user and in transmitting the packets with modified address to the device of the calling user. Once a message about the end of the communication session has been received, said message is retransmitted to the corresponding user device and the communication session is closed. |
