  • Patent number: 10110469
    Abstract: Systems, methods, and non-transitory computer-readable storage media for detecting network loops. In some embodiments, a system can identify a port that is in a blocking state. The blocking state can be for dropping one or more types of packets and preventing the port from forwarding the one or more types of packets. The system can determine a number of packets transmitted through the port by a hardware layer on the system and a number of control packets transmitted through the port by a software layer on the system. The system can determine whether the number of packets is greater than the number of control packets. When the number of packets is greater than the number of control packets, the system can determine that the blocking state has failed to prevent the port from forwarding the one or more types of packets.

  • Patent number: 10098066
    Abstract: The embodiments of the disclosure include methods and apparatus that provide back-off procedures for avoiding device/network resource depletion in bad network conditions. A device user may selectively enable an auxiliary back-off procedure that extends the time between network service requests. For example, the auxiliary back-off procedure may be used if the device determines an attach request is unsuccessful when a reject message is received from the network and the reject message indicates a reject cause for which the device has no defined back-off to follow. The auxiliary back-off procedure may be also be used if the device determines that a service request is unsuccessful when the service request is ignored, i.e. no response is received from the network, or, when a service request reject is received from the network and the reject message indicates a reject cause for which the device has no defined back-off to follow.

  • Patent number: 10079752
    Abstract: Systems, methods, and computer-readable storage media for detecting network loops. A system can identify, for each virtual tunnel endpoint (VTEP) from multiple VTEPs in a network, respective media access control address data including the respective local interface media access control addresses of the respective VTEP and respective media access control addresses learned by the respective VTEP. The system can determine whether the VTEPs are running spanning tree protocol (STP), and whether a media access control address learned by a first VTEP matches a respective local interface media access control address of a second VTEP. The system can detect a loop when the media access control address learned by the first VTEP matches the respective local interface media access control address of the second VTEP. The system can also detect a loop when the VTEPs are running STP and the first and second VTEPs see the same STP root bridge.

  • Patent number: 10075778
    Abstract: An integrated base station provides uplink and downlink wireless connectivity between user equipment and a wireless communication network. In order to accommodate certain features of the network, a bypass switch of the integrated base station is employed so that the baseband module of the base station is bypassed as to those features. In this case, selected data obtained from the RF transceiver of the integrated base station is processed by equipment in the back end system instead of by the baseband module. A first operation mode enables the baseband module to process the selected data, while a second operation mode bypasses the baseband module so that the back end system performs the processing. The bypass switch may be permanently activated. The bypass process allows for processing of the selected data in an efficient manner without requiring replacement of the integrated base station, thereby providing an efficient and cost-effective solution.

  • Patent number: 10070403
    Abstract: Technologies are described herein for time-synchronizing multiple remote network nodes concurrently with time beacons. A hub device in the network, at a preconfigured start time, begins to periodically broadcast time beacons containing current time values retrieved from an accurate time source over a beacon period, while other nodes of the network, at the same preconfigured start time, start listening for time beacons. When a node receives a time beacon broadcast by the hub device, the node sets a real-time clock of the node to the current time value in the received time beacon.

  • Patent number: 10063466
    Abstract: The described embodiments provide techniques and architectures for enabling interoperability between legacy network systems and Software Defined Networking (SDN) systems. The embodiments add functionality to an SDN system to support interworking between an SDN controlled network, and a legacy network. When upgrading a legacy system to SDN, it may not be possible to upgrade all network components at once. The described embodiments facilitate the use of legacy network components together with SDN system components, by adding new functionality to the SDN data plane elements and control plane elements. The SDN forwarding network elements (NEs) terminate the physical links carrying legacy protocols that include combined data traffic and control information.

  • Patent number: 10045244
    Abstract: A multi-antenna device configured for addressing connection performance issues in UL/DL imbalance scenarios is described. The device may identify a potential UL/DL imbalance scenario and select signal measurements associated with either a primary antenna or a diversity antenna for mobility procedures and/or mobility measurement reporting based on the detected imbalance. In one example, the device may receive a signal at both the primary and a diversity antenna and may identify an imbalance between the primary and diversity signal measurements. The device may then compare the identified imbalance with an imbalance threshold and may select the primary or diversity signal measurement for mobility procedures and/or measurement reporting based at least in part on the comparison. For instance, if the imbalance is greater than the imbalance threshold the device may use the primary signal measurements and may otherwise use the stronger of the primary or diversity signal measurements.

  • Patent number: 10045376
    Abstract: A method of channel access procedure and QoS provisioning is proposed. When more than one user equipments (UEs) contend uplink transmission for a given time slot in an unlicensed band, uplink listen-before-talk (LBT) scheme should perform in a proper way to reflect service prioritization. The base station first determines the Channel Access Priority (CAP) for uplink LBT, and then signals such CAP to the UE via PDCCH. Upon receiving the CAP, the UE performs LBT procedure with corresponding CAP before uplink transmission. For example, the CAP can be determined based on QoS class identifier (QCI) of the radio bearer or based on the MAC layer logical channel prioritization (LCP).

  • Patent number: 10039093
    Abstract: Embodiments of the present invention provide a control information sending method, receiving method, and device. The control information sending method includes: determining a first subframe of a first radio frame on a first carrier, where the first subframe includes a control region; sending control information in the control region of the first subframe of the first radio frame to a user equipment, where the control information includes a PDCCH; and sending an ePDCCH in a second subframe of the first radio frame to the user equipment. According to the embodiments of the present invention, when control information borne on an ePDCCH cannot be sent in a first radio frame, a PDCCH can still be sent to a user equipment through a control region in a first subframe, thereby achieving purposes of performing uplink/downlink scheduling for the user equipment and downlink feedback for uplink data of the user equipment.
