  • Patent number: 11153039
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for improved data transmissions using puncturing and error correction encoding. A decoder receives an encoded data input that includes a set of individual values. The decoder performing a puncturing of the encoded data input, yielding a punctured encoded data input that includes a subset of the individual values from the set of individual values. The decoder determines whether the punctured encoded data input maps to any predetermined data outputs from a set of predetermined data outputs, and in response to determining that the punctured encoded data input maps to a predetermined data output from the set of predetermined data outputs, the decoder determines that the encoded data input corresponds to the predetermined data output.

  • Patent number: 11071043
    Abstract: A method of enhanced handling of a Forbidden Public Land Mobile Network (PLMN) list is proposed. When a UE tries to attach to a PLMN and receives an ATTACH Reject message having no integrity protection, it could be transmitted from a network entity trying to block the PLMN for providing service. Therefore, by introducing a temporary forbidden PLMN list and a timer T3247, UE can avoid adding the PLMN ID to the Forbidden PLMN list and avoid being blocked for network access. Instead, UE is only temporary refrained from selecting the PLMN ID and is able to retry for the network access after T3247 expiry. The temporary list together with T3247 mechanism thus gives UE more opportunity to try with the same PLMN ID at a different time and/or a different UE location, where the malicious blocking is no longer available.

  • Patent number: 11070328
    Abstract: A wireless device receives one or more configuration parameters for uplink bandwidth parts (BWPs) of a cell. A first preamble, for a random-access procedure, is transmitted via a first uplink BWP of the uplink BWPs. A random-access response comprising a backoff indicator is received. A backoff window associated with the backoff indicator is started. A second uplink BWP of the uplink BWPs, that is different from the first uplink BWP, is selected for transmission of a second preamble during the backoff window. The wireless device transmits, via the second uplink BWP and based on the selecting, the second preamble for the random-access procedure.

  • Patent number: 11070321
    Abstract: Techniques for dropping packets at congested network elements for no drop traffic are described. A network element in communication with a congested network element initiates a copy packet queue and stores a copy of each transmitted no-drop packet sent to the congested element. When the network element receives an indication that the congested element has dropped a no-drop packet, the network element begins retransmission of the dropped packets to the congested element from the copy packet queue, thus providing a lossless network while allowing for dropped packets.

  • Patent number: 11032192
    Abstract: A node of an LSP may inform the ingress node of the LSP, for example via RSVP signaling, about its temporary unavailability for a certain time. In response, the ingress node can stop using any affected LSP(s) and divert the traffic to other LSPs. This provides a faster mechanism to signal traffic shift then traditional IGP overload which causes considerable churn into the network as all the nodes need to compute the SPF. It is sufficient for ingress node to be aware of this node maintenance and it can use information to divert the traffic to other equal cost multipath (ECMP) LSP(s), or other available LSP(s). If no alternative LSP path exists when the ingress node receives such a message, a new LSP can be built during this time and traffic diverted smoothly (e.g., in a make-before-break manner) before the node goes offline for maintenance.

  • Patent number: 10986021
    Abstract: Methods and apparatus are provided for managing data flows in a switch connected in a network. Such a method includes monitoring a set of data flows traversing the switch for compliance with a predetermined resource-usage policy, and, in response to detection of a non-compliant data flow, mirroring a set of data packets of that flow to send respective mirror packets to a mirror port of the switch. The method further comprises using the mirror packets sent to the mirror port to construct a non-compliance notification for the non-compliant flow, and sending the non-compliance notification into the network. The resource-usage policy can be defined such that the switch is operable to send a non-compliance notification before occurrence of congestion due to the non-compliant flow.
