  • Patent number: 11051239
    Abstract: At a network element, a first TEID is determined that is associated with a default bearer between a UE and a first APN. A determination is made whether a tunnel discovery procedure should be performed to discover a second TEID associated with a dummy bearer. The dummy bearer is associated with the UE and a second APN. The tunnel discovery procedure is performed to discover the second TEID, and the dummy bearer is set up between the network element and the UE. Data arriving at the network element from the core network and toward the UE is routed over one of the default bearer, using the first TEID, or the dummy bearer, using the second TEID. Data arriving at the network element from the UE and toward the core network is routed over only over the default bearer. Apparatus, methods, and computer programs and products are disclosed.

  • Patent number: 10455261
    Abstract: In one embodiment, a mobile communications system has a plurality of radio access network (RAN) nodes communicating wirelessly with a plurality of wireless user devices, a video server transmitting one or more packetized video streams to one or more of the wireless user devices, and a packet core routing packets of video data from the video server to the one or more wireless user devices via the RAN nodes. For each packetized video stream, the video server transmits in-band information related to the packetized video stream, such as relative screen size, relative video activity level, and minimum and maximum video quality levels, and each RAN node extracts and uses the in-band information to schedule transmission of the packets of video data to its one or more corresponding wireless user devices. The system can provide higher-quality video experience without wasting bandwidth on user devices that don't require much communication resources.
