  • Patent number: 11006344
    Abstract: A method for UE route selection policy (URSP) rule matching is proposed. URSP is used by a UE to determine if a detected application can be associated to an established PDU session, can be offload to non-3GPP access outside a PDU session, or can trigger the establishment of a new PDU session. The UE first finds a non-default URSP rule with a matching traffic descriptor to the application. When the UE fails to find existing PDU session or setup new PDU session with any or the route selection descriptors of the non-default URSP rule, the UE moves to another non-default URSP rule, if any, and try the matching. If all non-default URSP rules cannot be matched with the application, then the UE tries the default URSP rule, which includes a match-all traffic descriptor.

  • Patent number: 10972956
    Abstract: A method of QoS rule management with enhanced handling on QoS flow description is proposed. UE checks QoS configuration received from the network for QoS operation errors. When UE receives a QoS rule associated with a specific QFI but has no QoS flow description for the QFI, UE further determines whether the QoS rule is of a GBR QoS flow. If so, UE detects a QoS operation error. If the QoS rule is the default QoS rule, then UE releases the PDU session. If the QoS rule is not the default QoS rule, then UE either rejects a PDU session modification command that carries the QoS rule or deletes the QoS rule carried by a PDU session establishment accept with a 5GSM cause value indicating the QoS operation error.

  • Patent number: 10891246
    Abstract: A buffer (32) for temporarily storing a packet is installed in a packet order control circuit (12H). A comparison circuit (31) compares the packet ID of an input packet with a next-selection ID indicating the packet ID of a packet to be selected next in accordance with an order. If the comparison result indicates that the packet ID and the next-selection ID do not match, a control circuit (36) stores the input packet in a storage position corresponding to the packet ID. If the packet ID and the next-selection ID match, the control circuit (36) selects the input packet as a target of a transfer process without storing the packet in the buffer (32). If the next-selection ID matches the packet ID of a packet stored in the buffer (32), the control circuit (36) selects the packet as a target of the transfer process. This guarantees the packet processing order with few memory resources.

    Abstract: A method for exchanging ultra-short media content is provided. A media content item is recorded by a first computing device. The first computing device divides the recorded media content item into a plurality of ultra-short self-contained media fragments during the recording of the media content item. Each of the media fragments has a predefined maximum duration, e.g., several seconds. The first computing device processes the media fragments to generate service information associated with a corresponding media fragment while recording and dividing subsequent media fragments. The first computing device transmits the media fragments to a second computing device to view as a media stream while continuing to record, divide and process subsequent media fragments. Each of the media fragments is received one by one at the second computing device and displayed as an uninterrupted media stream while the subsequent media fragments are being received from the first computing device.

  • Patent number: 10764170
    Abstract: Some embodiments provide a method for a particular FE in a network of FEs. The method receives a data message at a first port of the FE. The data message includes a header that specifies an egress port for each FE along a path from a source of the data message to a destination of the data message and an ingress port for at least each FE along the path that the data message has previously traversed. The method determines that the particular egress port specified for the FE is a second port that is not operational. The method generates a path failure message specifying that the second port is not operational and including a header that uses the egress ports and ingress ports in the data message. The method sends the path failure message out of the first port for delivery to the source of the data message.

  • Patent number: 10715455
    Abstract: In one embodiment, for each distribution period of time, each packet flow is assigned to a path through a packet switching device (e.g., switch fabric) with all packets of the packet flow being sent in order over the assigned path. For a next distribution period, different paths are assigned for these packet flows, with all packets being sent in order over the new corresponding selected path. In one embodiment, these paths are switched often enough to prevent congestion, yet infrequent enough so as to minimize resources for reordering. In one embodiment, the reordering is done at the egress and only for predefined high bandwidth flows (e.g., elephant flows). A distribution period indication is typically associated with each packet to identify its corresponding distribution period. In one embodiment, each routing and egress switching stage in a switching fabric performs reordering.
