  • Patent number: 11122466
    Abstract: A DSL management system predicts achieving improved DSL line performance before a DSL optimizer optimizes performance of the DSL line. The system obtains a current state of performance of the DSL line before optimization and a target state of performance after optimization. The system further obtains a measure of DSL line characteristics and identifies, from records of performance information associated with DSL lines, a subset of records associated with a subset of DSL lines that have a similar measure of the DSL line characteristics as the DSL line for which achieving improved performance is predicted. The system obtains a probability that the DSL optimizer will optimize the performance of the DSL line based on a frequency with which the identified subset of records indicates that the optimizer previously has optimized the performance of the subset of DSL lines.

  • Patent number: 11109318
    Abstract: Methods, devices, and systems for retransmission of wake-up signals from a first station to a second station over a wireless network are disclosed. In some aspects, a wake-up signal is encoded for transmission to the second station. While the first station is waiting for an acknowledgment of the wake-up signal from the second station, the second station may retransmit the wake up signal and/or encode a packet for transmission to a third station. In some aspects, whether the wake-up signal is retransmitted is based in part, on at least one of whether a number of timeout events for wake-up signals transmitted to the second station exceeds a maximum timeouts threshold, whether a number of wake-up signals transmitted to the second station exceeds a maximum wake-up signals threshold; or whether a maximum predetermined elapsed time since a first wake-up signal was transmitted to the second station is exceeded.

  • Patent number: 11089515
    Abstract: A device can receive, at a radio access network (RAN) and from a user device, first information to initiate a communications session that has one or more properties. The device can send second information to an access and mobility management function component (AMF) to authenticate the user device. The device can send third information to a user plane function component (UPF) to determine a set of network slice policies for managing the communications session. The device can receive the set of network slice policies and apply the set of network slice policies to the communications session. The device can detect a change in the one or more properties of the communications session and send a signal to the UPF to analyze the communications session. The device can receive a new set of network slice policies and apply the new set of network slice policies to the communications session.

  • Patent number: 11088938
    Abstract: A method for routing communication traffic in a network includes detecting that a link in a parallel link configuration has failed and, in response, adjusting one or more metrics associated with other links in the parallel link configuration to indicate that none of the links in the parallel configuration are available. A router connected to a direct link in a parallel link configuration including one or more other routers connected to one or more indirect links, respectively, includes a memory storing configuration parameters specifying a minimum number of links required to be operational in the parallel link configuration and an artificially high cost, and a link metric adjustment module operable to set a metric of the direct link to the artificially high cost until the minimum number of required links are operational after startup of the router or failure and reactivation of the direct link.

  • Patent number: 11083021
    Abstract: An access point (AP) may prioritize the allocation of uplink resources between multiple basic service sets (BSSs). In some aspects, the AP may select one of a plurality of BSSs, may allocate one or more random-access resource units (RUs) to only the selected BSS, and may transmit, for each of the selected BSSs, a respective frame indicating the random-access RUs allocated to that BSS. Wireless devices belonging to the selected BSS may contend for access to the random-access RUs allocated by the frame, and then transmit uplink data using the random-access RUs.

  • Patent number: 11075965
    Abstract: In a staggercasting system, a receiver estimates a delivery time of a packet from a main stream and, if the packet from the main stream is not received at the estimated delivery time, the receiver substitutes a corresponding packet from the stagger stream. As a result, a loss can be detected quicker since the receiver does not have to wait until detection of a missing sequence number and, therefore, the receiver can accommodate the time of presentation such that the user does not suffer a loss in quality of service.

    Abstract: Embodiments can provide a downlink-beam detection method and an apparatus. Under the method a terminal device can be notified by a network device of information about a broadcast beam. The network device can receive a detection result reported by the terminal device. The detection result may pertain to broadcast beam detection performed based on the information about the broadcast beam. the network device can then determine, based on the detection result, a downlink beam that needs to be swept during downlink-beam adjustment and that is used for data communication. This reduces signaling overheads.

  • Patent number: 11051208
    Abstract: Resources used for downlink communication may be partitioned by the base station so that a portion of the resources is reserved for the downlink transmission of low latency data. However, low latency data may be bursty or sporadic in nature, and may be transmitted in short packets. Therefore, there may not always be low latency data at the base station that needs to be transmitted using all of the low latency resources. System and methods are therefore disclosed in which the base station opportunistically schedules, on the low latency resources, latency tolerant data for one or more latency tolerant UEs. When latency tolerant data is scheduled on the low latency resources, signaling is used to indicate if the latency tolerant transmission on the low latency resources is modified.

  • Patent number: 11044187
    Abstract: The present disclosure provides performance measurement (PM) for segment routing (SR) with flexibility to have PM information piggy backed, preferably using service function chaining (SFC) to data packet itself or dedicate PM packet avoiding change in data packet. A performance measured flow (PMF) identifier is used by transit/egress nodes for statistics collection for a given PMF. The PMF identifier is carried in the piggy backed information without the use of separate SR label. The Piggy backed information carries the node information role of the node used by transit egress nodes to collect statistics for a given PM segment. The present disclosure collects the statistics for multiple segments and multiple PM types using a metadata present in single received packet, saving bandwidth and making PM calculation fast and more accurate. Using the present disclosure, the timer/configuration requirement per performance measurement instance from transit/egress node is avoided.

  • Patent number: 10986694
    Abstract: Techniques are described herein for reordering beams used to transmit reference signals for subsequent beam sweeps of a beam management procedure. Beams used to transmit reference signals may be hierarchically ordered to enable a user equipment (UE) to terminate the beam management procedure early and thereby conserve power while operating in a discontinuous reception mode. A base station may transmit reference signals using a first ordered set of beams as part of a first beam sweep. The UE may transmit feedback information to the base station about the signal quality for at least some of the reference signals. The base station may generate a second ordered set of beams based on the feedback information. The base station may transmit the reference signals using the second ordered set of beams as part of a second beam sweep.
