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.

Abstract: Extending cellular telecommunication service from a first UE to another device. The first UE may register for cellular telecommunication service with a cellular network using a first cellular service account, using a cellular communication link via a cellular radio. A second device may be discovered and a communication link may be established between the first UE and the second device. The second device may be registered to use cellular telecommunication capability provided by the first UE. Communications between the second device and the cellular network may be conveyed via the communication link between the first UE and the second device and the cellular communication link. Conveying communications between the second device and the cellular network may provide use of the first cellular service account for cellular telecommunication service to the second device.

Abstract: A low-power roaming mechanism is described. This low-power roaming mechanism is used by a portable electronic device when the portable electronic device enters a stand-by mode (sleep mode). During this stand-by mode, the portable electronic device allows a wireless interface to look for surrounding wireless networks with a configurable quota. This quota is allotted for roaming based on the usage or communication pattern of the portable electronic device. Once the allotted quota is completely used, the portable electronic device is blocked from performing roaming operations to prevent the portable electronic device from draining the battery.

Abstract: A method and system are described for determining parameters of an access point (AP). In the described embodiments, during a first time period, a portable electronic device (PED) scans for APs on a wireless local area network (WLAN) channel. Then, when an AP is detected on the WLAN channel, the PED determines if the AP includes a general advertisement service (GAS) protocol to make available information related to services provided by the AP. If the AP includes the GAS protocol, then the PED transmits a GAS request frame to the AP. If a response to the GAS request frame is not received from the AP within the first time period, then the PED extends the dwell time to wait for the response for a second time period, wherein a duration of the second time period is determined based on a total allowable time to scan for APs.

Abstract: In order to facilitate reduced power consumption of an electronic device (such as a smartphone) when communicating with another electronic device (such as an access point) in a wireless network, the electronic device may change a wake policy based on the applications executing on the electronic device. In particular, the electronic device may monitor a subset of the applications currently executed by a processor in the electronic device, where the subset can include zero or more of the applications. Based on the subset, the wake policy of an interface circuit in the electronic device may be changed. This wake policy may specify a frequency of wake ups to receive information from the other electronic device and/or monitoring of unicast or multicast bits in a Traffic Indication Map element. In this way, the time that the electronic device is in the active mode can be reduced, thereby reducing power consumption.

Abstract: One embodiment of the present invention provides a system configured to apply Internet Protocol (IP) address based packet filtering prior to entering Wake on Wireless LAN (WoWLAN) mode. During operation, the system receives a request to enter WoWLAN mode. In response to this request, the system collects a set of active IP addresses, as well as a set of active ports. Next, the system filters out packets destined to IP addresses that are not members of the set of active IP addresses, and ports that are not members of the set of active ports. Finally, the system enters WoWLAN mode.

Abstract: The present disclosure describes a method for adaptive WiFi roaming, where an electronic device and an access point advertise their networking capability. The networking capability may be, for example, the capability to support at least one enterprise feature. Based on the advertisements transmitted by the electronic device, the access point can determine that the electronic device can support the at least one enterprise feature and may selectively enable the at least one enterprise feature. Additionally, based on advertisements transmitted by the access point, the electronic device can determine that the access point can support the at least one enterprise feature. Based on this mutual determination, the access point and electronic device may continue an association process based on the at least one enterprise feature.

Abstract: An apparatus and methods are provided for automatically detecting and connecting to a Wi-Fi network. In these methods, a wireless device listens for beacons that are sent using a low-power wireless protocol. Once the wireless device detects a first beacon at a first location, the wireless device extracts a first beacon region identifier from the beacon and correlates the first beacon region identifier with a first Wi-Fi network that is located at the first location. Next, the wireless device retrieves a first set of credentials for connecting to the first Wi-Fi network. Once the first set of credentials is retrieved, the wireless device uses the first set of credentials to connect to the first Wi-Fi network.

Abstract: An electronic device connects to a network associated with a service provider via a router at a home location. During a time interval, the electronic device provides information specifying a network address of the router to an authentication computer when the electronic device is connected to a network. The authentication computer uses the received information to determine a connection pattern of the electronic device. Moreover, the authentication computer identifies that the electronic device is at the home location based on the connection pattern. Then, the authentication computer provides, to an accounting computer associated with the service provider, a request to allow the electronic device to access a wireless network associated with the service provider at a remote location (which is other than the home location). Furthermore, the authentication computer communicates network information to the electronic device, which allows the electronic device to access the wireless network without providing authentication information.
