Abstract:
An example method may involve using a first IP:port number to receive from a second IP:port number a first media control channel stream including quality information indicative of a quality of transmission of a first media stream being sent through a network; sending from the first IP:port number to the second IP:port number a second media control channel stream including quality information indicative of a quality of transmission of a second media stream; based on a network handover request, sending from a third IP:port number to the second IP:port number a third media control channel stream including quality information indicative of a quality of transmission of a third media stream being received through an alternate network; and using the third IP:port number to receive from the second IP:port number a fourth media control channel stream including quality information indicative of a quality of transmission of a fourth media stream.
