Offloading a video portion of a video call

A wireless communication device comprising:

• a cellular interface configured to transmit data to and receive data from a cellular network;
• a wireless local area network (WLAN) interface configured to transmit data to and receive data from a WLAN;
• and
• processing circuitry coupled with the cellular interface and with the WLAN interface, the processing circuitry configured to control the wireless communication device to at least:
• participate in a video call with a remote device over a connection between the wireless communication device and the cellular network, the video call comprising a first video stream carried over a first bearer on the cellular network and a packet switched audio stream carried over a second bearer on the cellular network;
• establish a connection between the wireless communication device and the WLAN;
• perform a call setup procedure with the remote device to establish a second video stream, the second video stream being carried over the WLAN;
• terminate the first video stream after establishing the second video stream;
• and
• use the second video stream and the audio stream to continue the video call.

A non-transitory computer readable storage medium having computer program code stored thereon, the computer program code comprising program code, which, when executed by one or more processors implemented on a wireless communication device, is configured to cause the wireless communication device to perform a method comprising:

• participating in a video call with a remote device over a connection between the wireless communication device and a cellular network, the video call comprising 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;
• establishing a connection between the wireless communication device and a wireless local area network (WLAN);
• performing a call setup procedure with the remote device to establish a second video stream, the second video stream being carried over the WLAN;
• terminating the first video stream after establishing the second video stream;
• and
• using the second video stream and the audio stream to continue the video call.
