MULTI-STACK SUBSCRIBER SIGN ON

摘要

A system includes a multi-stack subscriber, a gateway, and a web portal. The web portal determines whether the subscriber is authenticated to access the Internet using a first Internet Protocol by receiving logon information from the subscriber. The subscriber requests to access the Internet using a second Internet Protocol. The gateway and/or the web portal determine whether the subscriber is authenticated to access the Internet using the second Internet Protocol without sending a second logon to the subscriber.
