  • Patent number: 10292205
    Abstract: A cellular-WLAN integration capability is presented herein. The cellular-WLAN integration capability provides an integration of a cellular network and a WLAN network that supports more efficient routing of downlink and uplink bearer traffic via cooperation of the cellular and WiFi interfaces in both the radio access network and at the end user device. The cellular-WLAN integration capability provides an integration of a cellular network and a WLAN network in which downlink bearer transmissions to an end user device may be selectively distributed between the cellular and WLAN networks and, similarly, uplink bearer transmissions from an end user device may be selectively distributed between the cellular and WLAN networks. The cellular-WLAN integration capability provides an integration of a cellular network and a WiFi network that tends to increase capacity for downlink bearer traffic while providing a reliable and efficient path for uplink bearer traffic.

  • Patent number: 10264588
    Abstract: One or more techniques and/or systems are provided for automatically forming a wireless sensor network, implementing power management for the wireless sensor network, and/or self-healing within the wireless sensor network. For example, hub devices, configured to forward messages through the wireless sensor network to a gateway device having access to a network, may automatically join and configure into the wireless sensor network by locating and connecting to master devices using signal frequencies representing numbers of hops to the gateway device. A hub device may be configured to transition between a low power sleep state for power conservation and an awakened normal operational state for transmitting timing signals according to a duty cycle, and thus the hub device may be capable of operating from a battery. If a hub device determines that a master device has become inoperable, the hub device may automatically search for a new master device.

  • Patent number: 10257828
    Abstract: Time-division duplexing (TDD) in distributed communications systems, including distributed antenna systems (DASs) is disclosed. In one embodiment, a control circuit is provided and configured to control the TDD transmit mode of a DAS to control the allocation of time slots for uplink and downlink communications signal distribution in respective uplink path(s) and downlink path(s). The control circuit includes separate power detectors configured to detect either a transmit power level in a downlink path or a receive power level in an uplink path. If the transmit power detected in the downlink path is greater than receive power detected in the uplink path, the control circuit switches the TDD transmit mode to the downlink direction. In this manner, the control circuit does not have to control the TDD transmit mode based solely on detected power in the downlink path, where a directional coupler may leak uplink power in the downlink path.

  • Patent number: 10230807
    Abstract: A method and apparatus for energy-optimized data transmission by OPC UA protocol in radio networks is disclosed. When OPC UA communication is operated in a mobile device, e.g. as mobile access to part of a plant for maintenance, monitoring, parameterization, transmission is frequently implemented by the OPC UA's own request-response based communication behavior. Since the device is rarely able to switch off the transmitter, the battery of the device is very quickly discharged. This poses a problem, particularly in the case of devices that are intended to respond promptly to infrequent warnings or events. However, when a client device is intended to provide notification in relation to one event only, the previous polling, i.e. the periodic interrogation is dispensed with and an alternative notification through means inherent in the mobile network is used. This method uses, for example, a mobile push service supplied by the network provider.

  • Patent number: 10218526
    Abstract: A novel method of conducting multicast traffic in a network is provided. The network includes multiple endpoints that receive messages from the network and generate messages for the network. The endpoints are located in different segments of the network, each segment including one or more of the endpoints. For a source endpoint to replicate a particular message (e.g., a data packet) for all endpoints belonging to a particular replication group (i.e., multicast group) within the network, the source endpoint replicates the particular message to each endpoint within the source endpoint's own segment and to a proxy endpoint in each of the other segments. Each proxy endpoint in turn replicates the particular message to all endpoints belonging to the particular replication group within the proxy endpoint's own segment.

  • Patent number: 10194467
    Abstract: Systems and methods are disclosed herein that relate to a mechanism at a radio access node(s) and a User Equipment (UE) that enable the UE to decide whether the UE can use a wireless channel for data transmission even when the UE senses the wireless channel as being busy during a listening phase of a Listen-Before-Talk (LBT) procedure. In some embodiments, the method of operation of the UE comprises performing a LBT procedure for an observed channel where a result of the LBT procedure being that the observed channel is busy and deciding to override the LBT procedure based on knowledge that the observed channel is busy due to transmission by a compatible UE and transmitting on the observed channel even though the result of the LBT procedure is that the observed channel is busy upon deciding to override the LBT procedure.
