A method and system for allocating services to a first subscriber of a first home service provider when the first subscriber is visiting a network associated with a visited service provider. A node of the visited network receives a request from the visiting first subscriber to receive a first service from the visited network. In response to the request, the visited network determines whether there are sufficient available resources of a first set of resources to provide the requested first service. When the available resources are insufficient to provide the requested service, then at least one pre-existing service supported by the first set of resources is preempted so that sufficient resources from the first set of resources are made available to provide the requested service, and the requested service is provided to the visiting first subscriber. |
