Abstract
Terminal-assisted selection of intermediary network for a roaming mobile terminal is disclosed. The mobile terminal determines if a local access network is associated with the mobile's home service network. If not, or if the mobile terminal cannot determine whether the local access network is associated with its home service network, the mobile terminal sends a list of intermediary service networks to the local access network. The local access network can select one of the intermediary service networks to be used in an authentication procedure between the mobile terminal the home service network.
