Patent ID: 7640565

Claim:
A method for downloading a video program using a mobile terminal, the method comprising the steps of: Downloading, to the mobile terminal, the video program at a first data rate from a first radio access network; continuing to download the video program at a second data rate from a second radio access network when the mobile terminal is in a coverage area of the second radio access network, wherein the second data transfer rate is faster than the first data transfer rate; displaying, at the mobile terminal, the downloaded video program at a playback rate; buffering, at the mobile terminal, portions of the downloaded video program that result when a rate at which the video program is downloaded exceeds the playback rate; calculating, at the mobile terminal, a third data transfer rate, which is lower than the first data transfer rate, in response to the playback rate, the buffered portions, and a time duration of a remainder of the video program; and negotiating, with the first radio access network, the third data transfer rate for continued downloading of the video program, when a difference between the first and third data transfer rates exceeds a threshold level.
