Signaling enabling status feedback and selection by a network entity of portions of video information to be delivered via wireless transmission to a ue

Abstract

A method includes exchanging signaling between a first entity providing access by a user equipment to a video stream and a second entity through which the video stream passes prior to being delivered via wireless transmission to the user equipment, the second entity receiving video information corresponding to the video stream, the exchanged signaling associated with the video information received at the second entity. Responsive to the exchanged signaling, sending information from the first entity to the second entity to modify status at the second entity of at least a portion of the video information previously received at the second entity. Another method includes at the first entity, receiving from a second entity an indication the second entity is capable of accepting multiple resolutions of a video in the video stream. Responsive to the received indication, the first entity sends to the second entity multiple resolutions of the video.

What is claimed is: 
     
         1 . A method, comprising:
 at a first entity providing access by a user equipment to a video stream, receiving from a second entity an indication the second entity is capable of accepting multiple resolutions of a video in the video stream, where video information in the video stream is to be delivered via wireless transmission to the user equipment and wherein the video stream passes through the second entity prior to being delivered via wireless transmission to the user equipment; and   responsive to the received indication, the first entity sending to the second entity multiple resolutions of the video in the video stream.   
     
     
         2 . The method of  claim 1 , further comprising the first entity sending a request to a second entity requesting whether the second entity is capable of accepting the multiple resolutions of the video in the video stream, and wherein the receiving is responsive to the request. 
     
     
         3 . The method of  claim 1 , further comprising the first entity receiving signaling from the second entity, the signaling comprising one or more indications that particular video information was or was not swapped with different video information. 
     
     
         4 . The method of  claim 3 , further comprising the first entity determining, based on the one or more indications, which one or more of the multiple resolutions of video should be sent and which of the multiple resolutions should not be sent for a set of frames of the video, and the first entity sending only the determined one or more multiple resolutions of a set of frames video to the second entity. 
     
     
         5 . The method of any one of  claim 1 , wherein the first entity comprises one of a media optimizer through which passes the video stream from a video server, an origin video server comprising a video corresponding to the video stream, or a surrogate video server comprising a cached copy of the video. 
     
     
         6 . The method of  claim 1 , wherein the second entity comprises a base station, a mobility management entity, a home base station gateway, or an evolved universal terrestrial access network entity.
