A roaming end system is a subscriber to the home network and operates within the foreign network, a message being transportable between the roaming end system and the home inter-working function through the serving inter-working function using a protocol that ensures in sequence delivery of data packets.

Abstract: An inter-working function selection system in a coupled data network is disclosed. The coupled data network includes a foreign network and a home network. The foreign network includes a foreign mobile switching center with a serving registration server. The home network includes a home mobile switching center with a home registration server and a plurality of unassigned home inter-working functions. A first end system is a subscriber to the home network and operates within the foreign network. The first end system includes an end registration agent to form a registration request, the end registration agent sending the registration request through the serving registration server to the home registration server, the home registration server including a module to select an active home inter-working function from the plurality of unassigned home inter-working functions based on the registration request.

Abstract: A coupled data network with an accounting system is disclosed. The coupled data network includes a foreign network and a home network. The foreign network includes a base station with an access hub and a foreign mobile switching center with a serving registration server, the access hub including a serving inter-working function, the serving inter-working function including a foreign accounting collection module. The home network includes a home mobile switching center with a home inter-working function, the home inter-working function including a home accounting collection module. An end system is a subscriber to the wireless data network and coupleable to the foreign access hub. The home and serving accounting collection modules collect accounting data on message traffic transported between the end system and a communications server through the home inter-working function and through the serving inter-working function.
