ABSTRACT:
The invention concerns providing a default subscription profile for controlling a roaming terminal device in a packet data based mobile communication network. A roaming terminal device requesting to use a gateway is detected. A request for a subscription profile for the roaming terminal device is sent from the gateway. A default subscription profile stored in a network element of the mobile communication network is sent to the gateway. The invention allows avoiding the need to transmit the subscription profile of the roaming terminal device from a home network of the roaming terminal device to the visited network. Thus real-time signaling and its associated delay are decreased. Furthermore, the subscription profile is accessible even when there are connection problems between the home network and the visited network.
