ABSTRACT:
Home network-assisted selection of an intermediary service network for a roaming mobile terminal is disclosed. The selection is based on a list of desired intermediary service networks generated using information associated with the mobile terminal's home service network. In one example embodiment, the list is provided to a central access server, which provides this information to a local access network to which the mobile terminal is requesting access. The local access network selects one of the networks included on the list of desired intermediary service networks obtained from the central access server. This example embodiment uses existing protocols without modification, and can be used in conjunction with other intermediary service network selection procedures, if desired.
