  • Dynamic backoff in Wi-Fi calling
    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.
