Abstract: A method for offloading a video portion of a video call form a cellular network to a WLAN is provided. The method can include a wireless communication device participating in a video call with a remote device over a connection between the wireless communication device and a cellular network. The video call can include a first video stream carried over a first bearer on the cellular network and an audio stream carried over a second bearer on the cellular network. The method can further include the wireless communication device establishing a connection between the wireless communication device and a WLAN; performing a call setup procedure with the remote device to establish a second video stream over the WLAN; terminating the first video stream; and using the second video stream and the audio stream to continue the video call.

Abstract: A method and apparatus for forced cell/RAT reselection is disclosed. In one embodiment, a cellular mobile communication device may attempt to access a network through a serving cell. Responsive to determining that access to the network is barred through the serving cell, the mobile communication device may determine if another cell is available through which it may obtain access to the network. If another cell providing network access is available, the mobile communication device may force reselection from the serving cell to the new cell. If no other cell providing access to the network is available to the mobile communication device, a forced reselection of a radio access technology may be performed.
