Claim:
A method for facilitating establishment of a data-path between a mobile station and a home access service network gateway (“ASN-GW”), comprising: a visited ASN-GW receiving a first message from an authentication, authorization, and accounting (“AAA”) server, the first message comprising an identification of a home ASN-GW associated with a mobile station; the visited ASN-GW receiving a first data-path request message from a base station, wherein the base station is serving the mobile station, and wherein the first data-path request message requests a path for data-packet communication for the mobile station that extends between the base station and the visited ASN-GW; and in response to receiving the first data-path request message from the base station, the visited ASN-GW using the received identification to send a second data-path request message to the home ASN-GW, wherein the second data-path request message requests a path for data-packet communication for the mobile station that extends between the base station and the home ASN-GW.
