METHOD AND SYSTEM FOR INTERWORKING A WLAN INTO A WWAN FOR SESSION AND MOBILITY MANAGEMENT
First Claim
1. A machine-implemented method for processing network traffic of a packet network, the method comprising:
- receiving, at a mobility gateway device (MGW), a request from a wireless local area network (WLAN) controller of a WLAN for accessing the Internet or a packet core network, the request originated from a user equipment (UE) communicatively coupled to the WLAN;
in response to the request, determining by the MGW whether there is an active session associated with the UE over a wireless wide area network (WWAN); and
communicating by the MGW an IP address to the WLAN controller that was assigned to the UE during the active session of the WWAN, wherein the WWAN assigned IP address is used by the WLAN controller to identify traffic to/from the user equipment while the UE is communicatively coupled to the WLAN and tunnel the UE traffic between MGW and WLAN controller.

Abstract
According to one aspect, a mobility gateway device (MGW) receives a request from a wireless local area network (WLAN) controller of a WLAN for accessing the Internet or a packet core network, where the request is originated from a user equipment communicatively coupled to the WLAN. In response to the request, the MGW is configured to determine whether there is an active session associated with the UE over a wireless wide area network (WWAN). If so, the MGW assigns an IP address to the UE that was assigned to the UE during the active session of the WWAN. The assigned IP address is used by the UE to access the Internet or the packet core network over the WLAN.

8. A network element, comprising:
-
an interface to receive a request from a wireless local area network (WLAN) controller of a WLAN for accessing the Internet or a packet core network, the request originated from a user equipment communicatively coupled to the WLAN; and a configuration unit, in response to the request, to determine whether there is an active session associated with the UE over a wireless wide area network (WWAN) and to communicate with the WLAN controller, the IP address that was assigned to the UE during the active session of the WWAN, wherein the assigned IP address is used by the WLAN controller to identify the traffic associated with the UE based on the WWAN assigned IP address and tunnel that traffic from the WLAN controller of the WLAN and the Internet or the packet core network using the assigned IP address. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A machine-readable storage medium storing instructions therein, which when executed by a processor, cause the processor to perform a method for processing network traffic of a data network, the method comprising:
-
receiving, at a mobility gateway device (MGW), a request from a wireless local area network (WLAN) controller of a WLAN for accessing the Internet or a packet core network, the request originated from a user equipment (UE) communicatively coupled to the WLAN; in response to the request, determining by the MGW whether there is an active session associated with the UE over a wireless wide area network (WWAN); and communicating by the MGW an IP address to the WLAN controller that was assigned to the UE during the active session of the WWAN, wherein the WWAN assigned IP address is used by the WLAN controller to identify traffic to/from the UE while the UE is communicatively coupled to the WLAN and tunnel that UE traffic between MGW and WLAN controller.
