  • Patent number: 11425744
    Abstract: In a 5G or 6G wireless network, a user device that wishes to transmit an uplink message must first transmit a scheduling request to the base station, generally in an allocated time-frequency region sized according to the number of user devices. In general, most of the user devices are not requesting access most of the time, and therefore most of the allocated region is blank. To reduce the amount of wasted resources, the base station can divide the user devices into sections, and allow the user devices to indicate which sections include at least one ready user device. Then, the base station can allocate a much smaller region containing only those indicated sections, and the ready user devices can send their requests in that smaller region. The base station can then determine which user devices request access, provide them with grants, and receive their messages.

  • Patent number: 11418426
    Abstract: A method for initializing the border gateway protocol (BGP) on network devices. The method includes initializing a plurality of BGP convergence variables corresponding to a plurality of BGP sessions with a plurality of peer network devices. The first network device initializes the plurality of BGP sessions with the plurality of peer network devices, and receives from each of the plurality of peer network devices, route updates and a plurality of markers. The BGP convergence variables are updated and it is determined that first network device has received all the route updates. The duration of the BGP session is less than a C_TIMEOUT value for that peer network device, exceeds an I_P_TIMEOUT value, where the C_TIMEOUT value is greater than the I_P_TIMEOUT value. The first network device updates a routing information base (RIB) using the route updates and updates a forwarding information base (FIB) using the updated RIB.

  • Patent number: 11398991
    Abstract: In some embodiments, an apparatus includes a switch fabric having at least a first switch stage and a second switch stage, an edge device operatively coupled to the switch fabric and a management module. The edge device is configured to send a first portion of a data stream to the switch fabric such that the first portion of the data stream is received at a queue of the second switch stage of the switch fabric via the first switch stage of the switch fabric. The management module is configured to send a flow control signal configured to trigger the edge device to suspend transmission of a second portion of the data stream when a congestion level of the queue of the second switch stage of the switch fabric satisfies a condition in response to the first portion of the data stream being received at the queue.

  • Patent number: 11363572
    Abstract: Methods, systems, and devices for wireless communication are described A user equipment (UE) and a base station may support switching from one waveform to another on uplink channels. For example, a UE and a base station may utilize both frequency division multiplexing (SC-FDM) waveform and an orthogonal frequency division multiplexing (OFDM) waveforms based on channel conditions and other factors. In some examples, a UE may switch for some uplink channels, and use a single waveform for other channels. For example, switching waveforms for channels that utilize frequency domain code division multiplexing (CDM) channel may interrupt the orthogonality of multiplexed transmissions. A UE may transition from one waveform to another either autonomously or based on an explicit indication from a base station. If a UE switches autonomously, it may send an indication of the transition to the serving base station.

  • Patent number: 11349938
    Abstract: A non-MNO PSP network maintains a table that maps external subscriber identifiers of UEs to intermediate subscriber identifiers of the UEs on an interface between the non-MNO PSP network and NHN(s). The non-MNO PSP network obtains an SCEF-related message including either an external subscriber identifier or an intermediate subscriber identifier for the UE. Using the table, the non-MNO PSP network forwards the SCEF-message to a serving NHN or to an external application. In another embodiment, an NHN maintains a table that maps internal identifiers of UEs within the NHN to intermediate subscriber identifiers that identify the UEs on an interface between the NHN and non-MNO PSP(s). The NHN obtains an SCEF-related message that includes an intermediate subscriber identifier or an internal identifier for the UE. Using the table, the NHN either processes the SCEF-related message within the NHN, or forwards the SCEF-related message to a non-MNO PSP outside the NHN.

  • Patent number: 11336561
    Abstract: An IP router capable of isochronous switching of a packetized media stream. According to an example, the IP router parses the RTP header within an incoming IP datagram to extract the RTP time stamp, which provides a time value for a unique IP Flow. By inspecting the header, the IP router can switch the flow at the point in time that the RTP time stamp value changes, or matches a target value. In one aspect, the IP router looks for the change in the RTP time stamp value and performs the switch based on the detected change. In another aspect, the IP router performs the switch at a specified time stamp value that can be unique to a group of signals or based on a common “sync” value published to all the ports of the IP router.
