Abstract
A method and apparatus are provided for dynamically redirecting mobile terminal home agent selection in a mobile IP network. A provisioning server assigns a preferred home agent to a group of mobile terminals based on one of a subscriber special services, subscriber connectivity, and home agent capacity. The provisioning server transmits the preferred home agent address to a home authentication, authorization, and accounting (AAA) server which updates a AAA database. The mobile terminal seeking access to the mobile IP network first registers with a configured home agent address stored in the mobile terminal. The configured home agent communicates with the home AAA server to authenticate the mobile terminal. The home AAA server fails the mobile terminal authentication request and provides the address of the preferred home agent. The mobile terminal reregisters with the preferred home agent to access the mobile IP network.
