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.
