Abstract
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.
Claims21
A method for enhancing routing of an authentication, authorization, or accounting-related (AAA) message associated with a roaming mobile terminal to a home service network, comprising:
- storing in a local access network associated with the mobile terminal, a list of one or more intermediary service networks preferred for possible use in routing the AAA message from the local access network towards the home service network;
- the local access network including the list with the AAA message;
- the local access network or one or more subsequent intermediary service networks selecting from the list an intermediary service network;
- and
- the local access network or the one or more subsequent intermediary service networks using the selected intermediary service network to convey the AAA message towards the home service network.
Apparatus for enhancing routing of an authentication, authorization, or accounting-related (AAA) message associated with a roaming mobile terminal towards a home service network, comprising:
- a memory for storing a list of one or more intermediary service networks preferred for possible use in routing the AAA message towards the home service network, and
- data processing circuitry for performing the following tasks:
- including the list with the AAA message;
- using the list to select an intermediary service network;
- and
- using the selected intermediary service network to convey the AAA request message towards the home service network.
Apparatus in a local access network for enhancing routing of an authentication, authorization, or accounting-related (AAA) message associated with a roaming mobile terminal towards a home service network, comprising:
- means for storing a list of one or more intermediary service networks preferred for possible use in routing the AAA message towards the home service network;
- and
- means for including the list with the AAA message;
- means for selecting from the list an intermediary service network;
- and
- means for using the selected intermediary service network to convey the AAA message towards the home service network.
