Patent ID: 7386316

Claim:
A method for video data delivery in 3G mobile systems, the method comprising the computer implemented acts of: determining whether a set of criteria is satisfied for using a combination network comprising at least one circuit-switched network and at least one packet-switched network for dispatching a first set of video frames; and if said set of criteria is satisfied, then dynamically calculating optimal dispatching patterns for dispatching said first set of video frames to a caller endpoint through said combination network; wherein determining whether said set of criteria is satisfied further comprises: determining whether said at least one circuit-switched network supports video calls; if said at least one circuit-switched network supports video calls, then determining whether said at least one circuit-switched network is available for placing a video call; and if said at least one circuit-switched network is available for placing said video call, then attempting to establish a first video call connection with said caller endpoint using said at least one circuit-switched network.
