15 15MEDIACON 2004 © 2001, Cisco Systems, Inc. Summary Multimedia services are based on IP. Multiple access technologies are currently in use. Multimedia mobility at IP layer is required to permit mobility across multiple types of access networks. Various standards groups leading to develop multimedia mobility solutions that cross the access technology boundaries: IETF, MWIF, and others
