ABSTRACT:
The present invention supports account monitoring for a mobile node by a home agent communicating with an AAA server computer. The home agent maintains accounting attribute information on system usage by a mobile node on a network. Attribute information is maintained and metered on the home agent in a data table. The home agent generates and transmits accounting messages containing the accounting attributes to the AAA server computer. The AAA server computer stores the attribute information in a memory for later billing.
