ABSTRACT:
A multi-mode mobile station includes a first interface for wireless communication with a wireless local area network (WLAN) and a second interface for wireless communication with a wireless wide area network (WWAN). The multi-mode mobile station may become engaged in one or more communication sessions via a first wireless network. Session information regarding these one or more communication sessions is stored in a storage system. In response to a handoff request, a control system evaluates the session information to determine which of the communication sessions, if any, can be continued via the second wireless network, in accordance with a policy. The user may be notified of any sessions that can not be continued via the second wireless network and/or continued at a reduced level of performance. If the user opts to complete the handoff, continuable sessions are continued via the second wireless network and non-continuable sessions are dropped.
