Enhancing user experience during handoffs in wireless communication
First Claim
1. A method for performing a handoff for a mobile device from a first radio station to a second radio station, the method comprising:
- buffering a first media data set, the first media data set being received through the first radio station;
if a second media data set is received through the second radio station, cross-correlating a tail portion of the first media data set and a head portion of the second media data set to generate a cross-correlated media data set and outputting the correlated media data set;
if no media data is received through the second radio station within a threshold, synthesizing a synthesized media data set and outputting the synthesized media data set, the threshold including at least one of a time threshold and a data amount threshold, the synthesizing including using a modeled portion of the first media data set; and
if no media data is received through the second radio station at the threshold, extending at least a portion of the first media data set to generate an extended media data set and outputting the extended media data set.

Abstract
A method for performing a handoff for a mobile device from a first radio station to a second radio station. The method includes buffering a first media data set that is received through the first radio station. The method also includes cross-correlating a tail portion of the first media data set and a head portion of a second media data set to generate a cross-correlated media data set, if the second media data set is received through the second radio station. The method further includes synthesizing, using a modeled portion of the first media data set, a synthesized media data set, if no media data is received through the second radio station within a threshold. The method further includes extending the first media data set to generate an extended media data set, if no media data is received through the second radio station at the threshold.

12. A system for performing a handoff for a mobile device from a first radio station to a second radio station, the system comprising:
-
a buffer for buffering a first media data set, the first media data set being received through the first radio station; a cross-correlation module for cross-correlating a tail portion of the first media data set and a head portion of a second media data set to generate a cross-correlated media data set, the cross-correlation being activated if the second media data set is received through the second radio station; a synthesizer module for using a modeled portion of the first media data set to synthesize a synthesized media data set, the synthesizer module being activated if no media data is received through the second radio station within a threshold, the threshold including at least one of a time threshold and a data amount threshold; and an extension module for extending at least a portion of the first media data to generate an extended media data set, the extension module being activated if no media data is received through the second radio station at the threshold. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
