Abstract: Systems, devices, and methods are described for allowing a first device to learn how to connect to a first network using information that a second device obtained about a second network that is related to the first network. The second device can perform a virtual network discovery of the first network on behalf of the first device. The second device can describe how to initiate one or more connections to the first network by modifying the information the second device obtained about the second network. The second device can send the information identifying how to initiate the connections to the first network to the first device. The first device can automatically initiate connections to the first network without requiring user input.

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: A method for dynamically adapting a traffic inactivity timer is disclosed. The method can include a wireless communication device determining a data traffic level on a wireless network interface and determining whether the data traffic level exceeds a threshold data traffic level. The method can further include the wireless communication device using a first inactivity timeout period for the traffic inactivity timer in an instance in which it is determined that data traffic level does not exceed the threshold data traffic level. The method can additionally include the wireless communication device using a second inactivity timeout period for the traffic inactivity timer in an instance in which it is determined that the data traffic level exceeds the threshold data traffic level. The second inactivity timeout period can define a longer time period than the first inactivity timeout period.

Abstract: An electronic device is described. In order to facilitate the communication of synchronization information with another electronic device in a wireless network, the electronic device provides a request for the synchronization information to the other electronic device at a time other than a predefined synchronization transmission time of the other electronic device. Then, the electronic device receives the synchronization information from the other electronic device in response to the request. In this way, the probability that the synchronization information is successfully communicated is increased, and the amount of time the electronic device is in an active mode is reduced, thereby reducing power consumption.

Abstract: One embodiment of the present invention provides a system that facilitates offloading neighbor discovery from a host prior to the host entering Wake on Wireless LAN (WoWLAN) mode. During operation, the system receives a request from a host executing on the processor to enter WoWLAN mode. Next, the system collects a set of active IP addresses on the host. The system then places the apparatus in WoWLAN mode. Next, the system receives neighbor discovery requests from IP addresses external to the host at a networking chip external to the processor. The system then responds to the neighbor discovery requests from the networking chip on behalf of the host and without waking the host from WoWLAN mode for requests destined to IP addresses that are members of the set of active IP addresses. Finally, the system also prevents, at the networking chip, the neighbor discovery requests from waking the host.

Abstract: A device implementing an adaptive wide area network (WAN) link assessment system may include a processor configured to transmit data to a WAN over a first link on a first wireless interface. The processor may be configured to, responsive to a determination based on connection information that a first escalation condition is satisfied, configure the first link to provide expanded connection information. The processor may be configured to, responsive to a second determination based on the expanded connection information that a second escalation condition is satisfied, perform a probe operation with respect to a server on the WAN over the first link. The processor may be further configured to, when the probe operation is not successfully completed within a predetermined amount of time, begin to transmit the data to the WAN over the second link on the second wireless interface.

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: Some embodiments enable low power mode for wireless local area network (WLAN) subsystem of an electronic device to improve power usage at the electronic device and increase response time of the WLAN subsystem to prioritized application(s). For example, a method includes enabling a sleep mode of the WLAN subsystem of the electronic device. The electronic device maintains a connection with an access point of a wireless network during the sleep mode. The method further includes receiving a request from an application to communicate with the wireless network. The application is included in a list of prioritized applications. In response to determining that a metric associated with the sleep mode does not exceed a power budget, the sleep mode of the WLAN subsystem is suspended and the communication between the application and the access point of the wireless network is enabled (after the suspension of the sleep mode).

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.
