Method and system for managing communication sessions during multi-mode mobile station handoff
First Claim
1. A method for communication session management for a multi-mode mobile station, said multi-mode mobile station having a first interface for wireless communication with a first wireless network and a second interface for wireless communication with a second wireless network, said method comprising:
- establishing at least one communication session with said multi-mode mobile station via said first wireless network;
storing session information regarding said at least one communication session;
said multi-mode mobile station registering via said second wireless network;
after registering via said second wireless network, said multi-mode mobile station transmitting a handoff request via said second wireless network;
receiving said handoff request; and
in response to said handoff request, evaluating said session information to determine, in accordance with a policy, which of said at least one communication session, if any, can be continued via said second wireless network, wherein said policy considers bandwidth availability in said second wireless network.

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.

13. A system for communication session management for a multi-mode mobile station, said multi-mode mobile station having a first interface for wireless communication with a first wireless network and a second interface for wireless communication with a second wireless network, said system comprising:
-
a first-network storage system for storing first-network session information regarding first-network communication sessions established with said multi-mode mobile station via said first wireless network; a second-network storage system, separate from said first-network storage system, for storing second-network session information regarding second-network communication sessions established with said multi-mode mobile station via said second wireless network; a first-network evaluation system for evaluating, in response to a second-to-first network handoff request, said second-network session information to determine, in accordance with a first-network policy, which of said second-network communication sessions, if any, can be continued via said first wireless network, wherein said first-network evaluation system obtains said second-network session information from said second-network storage system; and a second-network evaluation system, separate from said first-network evaluation system, for evaluating, in response to a first-to-second network handoff request, said first-network session information to determine, in accordance with a second-network policy, which of said first-network communication sessions, if any, can be continued via said second wireless network, wherein said second-network evaluation system obtains said first-network session information from said first-network storage system. - View Dependent Claims (14, 15)

16. A method for session handoff between a first wireless network and a second wireless network for a multi-mode mobile station, said multi-mode mobile station having a first interface for wireless communication with said first wireless network and a second interface for wireless communication with said second wireless network, said method comprising:
-
establishing a plurality of communications sessions with said multi-mode mobile station via said first wireless network, said plurality of communication sessions including a first communication session and a second communication session; storing session information regarding said plurality of communication sessions in a storage system; receiving a handoff request after said storage system has stored said session information; in response to said handoff request, evaluating said session information to determine, in accordance with a policy, which of said plurality of communication sessions, if any, can be continued via said second wireless network, wherein said policy considers bandwidth availability in said second wireless network. - View Dependent Claims (17, 18, 19, 20)
