  • Patent number: 9787491
    Abstract: Systems and methods are disclosed for interleaving communications with a home area network (HAN) and a data network. A gateway device interleaves communications within timeslots of a time slotted channel hopping protocol. A gateway device can be configured to determine, during a first portion of a timeslot, whether the gateway device received a portion of a message from a data network. If the gateway device receives no messages from the data network during the first portion of the timeslot, the gateway device switches to listen for communication from the HAN during a second portion of the timeslot. If the gateway device receives a portion of the message from the HAN, the gateway device continues to receive receives the remainder of the message until one or more trigger conditions that cause the gateway device to listen for communication from the data network.

  • Patent number: 9775102
    Abstract: Methods and systems are described for determining an optimal access point for a client device based on the relative difference between signal strengths of wireless signals received by the client device from access points. In particular, the signal strengths of wireless signals received by a client device from access points are determined without receipt of signal strength and/or transmit power information from the client device. Instead, the signal strength difference value may be determined based on known characteristics of signals transmitted by the access points and known characteristics of signals received by the access points from the client device. This relative difference value may thereafter be used to determine an appropriate access point to provide network access to the client device.

  • Patent number: 9756553
    Abstract: A method and system provide assisted acquisition of a wireless link between user equipment and a femtocell unit. After an initial calibration of timing and/or frequency information, the user equipment enters into a low-power state. The femtocell unit monitors for system updates using a network listen module that sniffs the air interface of one or more neighboring cells. Upon a trigger event, the femtocell unit provides aiding information, for example, timing and/or frequency information corresponding to a change in timing and/or frequency of the air interface, over a second radio, e.g., a wireless personal area network interface. Thus, the user equipment may remain in the low-power state and receive updates with respect to the wireless wide area network interface. Subsequently, upon wake-up, the user equipment may utilize the aiding information, for example, to recalibrate its timing and/or frequency. Thus, acquisition of the wireless link with the femtocell unit may be expedited.

  • Patent number: 9749236
    Abstract: Handling of ELS REQ and RSP packets that contain addresses in the payload is shifted to the edge fabric switches connected to the node devices issuing and receiving the ELS REQ packet, the ingress and egress switches. This allows the ELS REQ and RSP packet payload address modification operations to be removed from the tasks handled by the router processor. As this removes a processing burden from the router processors, those router processors are free to handle other normal operations, thus allowing more processor bandwidth to be provided to those other operations, which allows further growth of the network as one limitation has been removed. The need to replicate or provide commands between switches or routers is avoided as there are no redundant paths at that point.

  • Patent number: 9749877
    Abstract: A method and apparatus are used for detecting a radio link (RL) failure and a post verification process. A quality of a downlink fractional dedicated physical channel (F-DPCH) is monitored once a transmission on an enhanced dedicated channel (E-DCH) has begun. It is determined whether the quality of the downlink F-DPCH is below a predefined threshold. If the quality is below the predefined threshold, then an occurrence of an RL failure is declared and a transmission over the E-DCH in a cell forward access channel (CELL_FACH) state is terminated. In a case of the post verification failure, E-DCH resources are released.

  • Patent number: 9742702
    Abstract: A method in a network element includes processing input packets using a set of two or more functions that are defined over parameters of the input packets. Each function in the set produces respective interim actions applied to the input packets and the entire set produces respective end-to-end actions applied to the input packets. An end-to-end mapping, which maps the parameters of at least some of the input packets directly to the corresponding end-to-end actions, is cached in the network element. The end-to-end mapping is queried with the parameters of a new input packet. Upon finding the parameters of the new input packet in the end-to-end mapping, an end-to-end action mapped to the found parameters is applied to the new input packet, without processing the new input packet using the set of functions.
