NETWORK DEVICE AND TERMINAL FOR MULTI-NET AGGREGATION TRANSMISSION, AND OPERATING METHOD THEREOF

A method for a terminal operating for a multi-net aggregation service comprises the steps of: transmitting, to an authentication server, a first message requesting the activation of a multi-net aggregation service; receiving, from the authentication server, a second message which is a response to the first message; and if response information included in the second message is a consent to the request, accessing a gateway positioned on a point of contact of the multi-net.
