ABSTRACT:
A method of and apparatus for controlling a data transfer by a transfer deliverer node from a terminal equipment belonging to the transfer deliverer node to another node, in a network system having a plurality of nodes connected to a public switched network and a plurality of terminal equipments connectable to a corresponding node. At each node, a discriminator specific to each terminal equipment belonging to the transfer deliverer node is registered in advance in a first memory; a discriminator specific to a user of each terminal equipment is registered in advance in a second memory for each terminal equipment belonging to the transfer deliverer node; in response to a data communication request from the terminal equipment belonging to the transfer deliverer node, the discriminator of the terminal equipment and the discriminator of a user of the terminal equipment, respectively sent from the terminal equipment, are received; it is judged if the received discriminator of the terminal equipment is being registered in the first memory; it is judged if the received discriminator of a user of the terminal equipment is being registered in the second memory as a discriminator of the user of the terminal equipment; and in response to the judgment results, it is determined if a data transfer from the terminal equipment is permitted or not.
