  • Patent number: 11025694
    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.
    Type: Grant

  • Patent number: 9307450
    Abstract: The teachings herein describe methods and apparatuses for caching content at the “edge” of a wireless communication network, based on operating one or more RAN caches within the RAN portion of the network under the control of a gateway cache that operates at the packet data network interface level within the CN portion of the network. Each RAN cache operates as subordinate of the gateway cache, based on intercepting content requests from wireless devices operating within the RAN, providing corresponding proxied content requests to the gateway cache, and serving or not serving requested content from the RAN cache in dependence on control signaling from the gateway cache. Such operation permits all decision making to reside in the gateway cache, thereby retaining full visibility for critical billing and lawful intercept functions, while obviating in many instances the need to back haul such content.
