Subscriber Management

The Mobile IP home agent interoperates with the subscriber management application on E-series routers. The subscriber management application enables customers to dynamically provision new IP subscribers and quickly create new value-added services.

You can set up your subscriber management environment to create dynamic IP subscriber interfaces to provision subscribers and provide differentiated service delivery. In this configuration, the service parameters for an IP subscriber are bound to a dynamic IP subscriber interface.

During the registration process when the Mobile IP home agent has authenticated the subscriber with AAA, the home agent locates or creates the appropriate IP tunnel to carry the data traffic to the foreign agent. When Mobile IP obtains all of the parameters required for interface creation, including the tunnel ID and the authentication context, it directs the subscriber management application to create the dynamic IP subscriber interface.

During the re-registration process when there is a handoff from an initial Mobile IP foreign agent to a new Mobile IP foreign agent, the home agent reauthenticates the subscriber with AAA and locates or creates the appropriate IP tunnel to carry the data traffic to the new foreign agent. When Mobile IP obtains all of the parameters required for interface creation, it directs the subscriber management application to move the dynamic IP subscriber interface from the initial tunnel for the previous foreign agent to the new tunnel that points to the new foreign agent. If this was the last subscriber on the tunnel for the previous foreign agent, then the home agent directs the IP tunneling application to tear down the initial tunnel.
