Abstract
An electronic device including a communication module configured to connect a packet based video call to a user equipment, an image processing module configured to generate a transmission image for the video call, and a control module configured to control a frame type of a transmission image generated by the image processing module based on tune-away information received from the user equipment.
Claims20
An electronic device comprising:
- a communication module configured to connect a packet-based video call to a user equipment (UE);
- an image processing module configured to generate a transmission image for the packet-based video call;
- and
- a control module configured to control a frame type of the transmission image generated by the image processing module based on tune-away information received from the user equipment.

An electronic device comprising:
- a processor:
- a memory;
- and
- a communication module configured to support a packet-switched (PS) network and a circuit-switched (CS) network,
- wherein when the communication module performs a tune-away operation for receiving CS paging information, instructions stored in the memory being executed by the processor comprises an instruction for transmitting tune-away information on the tune-away operation to a user equipment in a video call by the PS network.
