Subscriber Access in a Wireless Roaming Environment
When subscribers log in to a wireless location that has a roaming agreement with other locations, the following sequence of events occurs:
Subscribers connect to the local wireless location and provide login information on a portal page that provides a universal access method. This login information is forwarded to the SAE.
Based on the login information, an access service starts.
The subscriber is authenticated by RADIUS; the authorization includes RADIUS vendor-specific attributes for WISPr.
Policies are activated for the subscriber on the router.
After successful start of the access service, the portal page redirects the subscriber to a specified start page.
Figure 4 shows how subscribers interact with an SAE-managed wireless location that has a roaming agreement with wireless locations.
