Abstract
The present invention provides a method for facilitating mobile communication of a subscriber associated with a home network roaming in a visited network, even when the visited network has a No-Roaming Agreement (NRA) with the home network. The method includes detecting at a switching unit associated with the visited network, a registration attempt by the subscriber to register with the visited network. The method further includes authenticating by the switching unit, the subscriber with the home network via a sponsoring network that has a roaming agreement with the home network. Finally, the method includes sending by a service node, a trigger profile information to the switching unit in response to the registration attempt so as to enable redirection of call control associated with the subscriber to the service node. The service node thereafter allows the subscriber to perform call and non-call related mobile activities in the visited network.
