  • Publication number: 20170026884
    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: 9549337
    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.

  • Publication number: 20160234749
    Abstract: Techniques are disclosed relating to a mobile device that initiates handovers from short-range networks to long-range networks. In various embodiments, a mobile device includes one or more radios that communicate using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. In such an embodiment, the mobile device stores an indication that the cellular RAT is a preferred RAT for a communication session. The mobile may establish the communication session using the preferred RAT, and in response to determining that a quality of the preferred RAT fails to satisfy a set of quality criteria, may request that the communication session use the short-range RAT. In some embodiments, the mobile device analyzes average packet error rate for the communication session and in response to the average packet error rate satisfying a threshold, requests that the communication session use the cellular RAT.

  • Publication number: 20160219474
    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.

  • 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.
