Abstract

A scheme for managing ABR streaming of content in a wireless radio network environment that may have radio white spot areas. Upon determining that the wireless UE device executing an ABR client application is in a radio white spot area, the current ABR streaming session may be suspended at a particular segment. Thereafter, playback of other content locally cached at the wireless UE device may be commenced in lieu of the ABR media segments. When the wireless UE device exits the radio white spot area, the ABR streaming session may be resumed from a point adjacent to the particular segment where the ABR streaming session was suspended.
