Abstract
Enhanced routing of an authentication, authorization, or accounting-related (AAA) message between a local access network being accessed by a roaming mobile terminal and a home service network is described. A list of one or more intermediary service networks use in routing an AAA message between the mobile terminal and the home service network is generated or retrieved and stored. The list is used in routing the AAA message, whether originated from the local access network or originated from the home network.
Claims23
A method for enhancing routing of an authentication, authorization, or accounting-related (AAA) message related to a roaming mobile terminal from a home service network to a local access network being accessed or otherwise serviced by the roaming mobile terminal, comprising:
- storing in the home service network a list of one or more intermediary service networks for use in routing the AAA message from the home service network towards a local access network associated with the mobile terminal;
- the home service network including the list with the AAA message;
- and
- using the one or more intermediary service networks on the list to convey the AAA message towards the local access network.
Apparatus in a home service network for enhancing routing of an authentication, authorization, or accounting-related (AAA) related to a roaming mobile terminal from a home service network to a local access network being accessed or otherwise serviced by the roaming mobile terminal, comprising:
- a home service network memory for storing a list of one or more intermediary service networks for routing the AAA message from the home service network towards a local access network associated with the mobile terminal, and
- data processing circuitry for performing the following tasks:
- including the list with the AAA message, and
- directing the AAA message towards the local access network using the one or more intermediary service networks on the list.
A system comprising:
- a roaming mobile terminal;
- a local access network currently serving the mobile terminal;
- one or more intermediary service networks;
- and
- a home service network for enhancing routing of an authentication, authorization, or accounting-related (AAA) message from a home service network to the local access network including:
- means for storing in the home service network a list of one or more intermediary service networks for use in routing the AAA message from the home service network towards the local access network;
- means for including the list with the AAA message;
- and
- means for using the one or more intermediary service networks on the list to convey the AAA message towards the local access network.
