Abstract
A method and system of providing a roaming data service to a User Equipment (UE) that requires a dual attachment to a Packet Switched (PS) network for the data service and a Circuit Switched (CS) network for a voice service, but the visited network is a data-only PS network. When the UE sends a dual attach request, the visited network communicates with the home network via a Diameter Agent to obtain the UE's PS profile needed to complete attachment of the UE in the visited network for data services. To enable CS attach of the UE with the visited network, a custom function, titled a SGs-Agent, is deployed. The SGs-Agent provides a predefined CS profile to the visited network, thereby enabling the UE to complete the CS attach with the visited network. The visited network provides data services to the UE, but the voice services are denied.
