  • Publication number: 20160174280
    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: 9312988
    Abstract: A method for redundant transmission of real time data is provided. The method can include an edge node in a wireless network sending a first RTP packet including a first real time data frame to a second edge node. The method can further include the edge node determining that a radio link condition is sufficient to support redundant transmission of real time data to the second edge node. The method can additionally include the edge node, in response to determining that the radio link condition is sufficient to support redundant transmission of real time data, bundling the first real time data frame with a next sequential real time data frame that has not been previously sent to the second edge node in a second RTP packet at a PDCP layer of the edge node; and sending the second RTP packet to the second edge node.

  • Publication number: 20160080995
    Abstract: In some embodiments, a user equipment device (UE) may be configured to perform handover of a communication session from a first packet data network (PDN) to a second PDN. The UE may include a radio and processing circuitry coupled to the radio and configured to interoperate with the radio. The radio may include one or more antennas for performing wireless communications over at least a first packet data network (PDN) (i.e., packet-switched network) and a second PDN. The UE may be configured to communicate over the first PDN according to first context information that was assigned to the UE and initiate a handover operation from the first PDN to the second PDN. In response to initiating the handover operation, the UE may communicate over the second PDN using the first context information for at least a first time duration.

  • Publication number: 20160073286
    Abstract: In order to improve the quality of a telephone call communicated over a wireless local area network (WLAN), an electronic device (such as a cellular telephone) may obtain one or more performance metrics based on communication with another electronic device (such as an access point) via a connection in the WLAN. For example, the electronic device may receive the one or more performance metrics from the other electronic device and/or may determine the one or more performance metrics based on the performance of the communication. Then, the electronic device may compare the one or more performance metrics with an interference criterion. If the interference criterion is met, the electronic device may perform a remedial action, such as selectively discontinuing use of the WLAN to communicate the telephone call for a time interval. Otherwise, the electronic device may continue using the WLAN to communicate the telephone call.

  • Patent number: 9159085
    Abstract: A method includes sending a request to a user indicating options to modify a quality of experience for one or more application flows between a radio network and a mobile node used by the user. The request indicates the user should select one of the following: declining an option to upgrade an existing service to a new service able to support the one or more application flows with a higher quality of experience than supported by the existing service; or accepting an option to upgrade the existing service to the new service. In response to receiving an indication the user selected the option to upgrade the existing service, performing one or more actions to upgrade the existing service to the new service. The option to upgrade the existing service can include an option of receiving advertisements for the new service or paying extra for the new service.

  • Publication number: 20150095955
    Abstract: An electronic device uses one antenna to wirelessly communicate information with two different wireless networks via concurrent connections associated with different radio access technologies. More specifically, the electronic device may receive video via a first of the connections using a multicast communication protocol. In order to maintain the second connection, the electronic device may switch, for a time interval, from the first connection to the second connection during switching events. This switching can disrupt displayed content associated with the video. To prevent this disruption, in response to a trigger that warns of an upcoming switching event, the electronic device accesses a portion of the video in a buffer during the time interval associated with the switching event. When the communication circuit switches back to the first connection after the switching event, the electronic device reverts to the video communication using the multicast communication protocol.

  • Publication number: 20150031367
    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.
