  • Patent number: 10085294
    Abstract: A client device and a host device may create a local connection for providing wide area network access, such as Internet access, to the client device. In some embodiments, the client device may have limited network capabilities and may not be able to access the Internet without the host device. The client device may provide its speed and direction in a message to potential host devices. A host device may calculate a suitability metric, based on the speed and direction of the client as well as connection properties of the networks, which indicates an ability for the host device to connect the client device to the Internet. The host device may provide the suitability metric within a connection request to the client device. Based on the suitability metric and/or other factors, the client device and the host device may establish the local connection.

  • Patent number: 10039148
    Abstract: A user equipment (UE) device may be configured to effectively manage coexistence of multiple radio access technologies (RATs) on the device. Respective controllers responsible for at least partially managing wireless communications according to corresponding respective RATs may communicate to each other expected data transfer patterns that take place over their respective communications links, including application-specific data transfer patterns and data-transfer-mechanism-specific data transfer patterns. The RAT controllers may manage their respective data transfers according to the expected data-transfer pattern information associated with the other RATs received from each in order to prevent data transmission by the device over one RAT link interfering with data transmission of the device over another RAT link.

  • Patent number: 9860485
    Abstract: In video conferencing over a radio network, the radio equipment is a major power consumer especially in cellular networks such as LTE. In order to reduce the radio power consumption in video conferencing, it is important to introduce an enough radio inactive time. Several types of data buffering and bundling can be employed within a reasonable range of latency that doesn't significantly disrupt the real-time nature of video conferencing. In addition, the data transmission can be synchronized to the data reception in a controlled manner, which can result in an even longer radio inactive time and thus take advantage of radio power saving modes such as LTE C-DRX.

  • Publication number: 20170374598
    Abstract: A wireless communication system is presented for robust mobility management in a HetNet communication system. A source cell can prepare a macro cell and a target small cell as handover candidates during handover decision making and/or preparation. The mobile device is informed about the prepared macro cell and target small cell using radio resource control (RRC) messaging. After receiving a handover command or detecting radio frequency (RF) loss, the mobile device can try to connect with the target small cell. If the mobile device is unable to connect to the target small cell, the UE can fall back and connect to the macro cell.

  • Patent number: 9769723
    Abstract: An apparatus, system, and method for performing handover of a mobile station (MS) between a base station (BS) and an access point (AP) are described. In one embodiment, the MS may receive one or more threshold values for reporting measurements to the BS. The MS may convert the threshold values to device-specific threshold values. The MS may determine one or more network quality values associated with the AP. The MS may compare the network quality values to the device-specific threshold values. In response to the network quality values exceeding the device-specific threshold values, the MS may convert the network quality values to calibrated network quality values. The MS may provide the calibrated network quality values. The MS may perform handover from the BS to the AP based on providing the calibrated network quality values to the BS.

  • Patent number: 9750075
    Abstract: Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to antennas. An electronic device may include a baseband processor and other storage and processing circuitry that implements protocol stacks for handling multiple radio access technologies. The storage and processing circuitry may use the transceiver circuitry to convey data using a first radio access technology while periodically interrupting the conveying of the data to monitor a paging channel using a second radio access technology. In performing the paging channel monitoring operations, the storage and processing circuitry may enforce a time limit that ensures that operations using the first radio access technology are not disrupted more than desired.

  • Patent number: 9749915
    Abstract: In some embodiments, a user equipment device (UE) implements techniques for avoiding conflicts between UE-initiated and network-initiated handovers. In one embodiment, one or more first radios are configured to perform cellular communication using different first and second cellular radio access technologies (RATs) and a second radio is configured to perform wireless communication using a short-range RAT. In one embodiment, the mobile device is configured to, while communicating using the first cellular RAT, in response to determining that an inter-RAT handover to the short-range RAT is likely to be initiated or has been initiated by the at least one processor, delay sending a measurement report to the cellular base station. This delay may avoid conflict between handovers initiated by the network in response to the measurement report (e.g., from the first cellular RAT to the second cellular RAT) and the inter-RAT handover.
