Abstract

A method for using broadband network resources includes providing simultaneous access to an asynchronous transfer mode switched virtual circuit for a plurality of sessions. The access for each session is provided based on an internet protocol session request being received at a service gateway for the sessions. The method also includes tearing down the asynchronous transfer mode switched virtual circuit when all of the sessions are terminated.
