Abstract
A method of activating a packet data protocol context for a roaming terminal in a telecommunication system including a home network, a gateway support node to external packet networks, the node being used in the home network, at least one terminal and a visited network. When the terminal requests for packet data protocol context activation in the visited network, the visited network defines the gateway support node address on the basis of the network identifier and a subscriber identifier transmitted by the terminal. On the basis of the defined address, a request for packet data protocol context activation is transmitted from the visited network to the gateway support node and the activation of the packet data protocol context is finished.
