Enhanced routing of an authentication, authorization, or accounting-related (AAA) message between a local access network associated with a roaming mobile terminal and a home service network is described. A list of one or more intermediary service networks preferred for possible use in routing an AAA message between the mobile terminal and the home service network is generated or retrieved and stored. When an AAA message is detected, the list is included with the AAA message. The list is then used in routing the AAA message.
