Abstract: Some aspects of this disclosure relate to implementing a thread device that can associate with a thread network. The thread device includes a network processor, a first memory, and a host processor communicatively coupled to the network processor and the first memory. The first memory can be a nonvolatile memory with a first level security protection, and configured to store a first dataset including thread network parameters for the network processor to manage network functions for the thread device associated with the thread network. The host processor is configured to perform various operations associated with the first dataset stored in the first memory. The network processor can be communicatively coupled to a second memory to store a second dataset, where the second dataset has a same content as the first dataset. The network processor is configured to manage the network functions based on the second dataset. The second memory can be a volatile memory with a second level security protection that is less than the first level security protection.

Abstract: A device, system, and method uses a high power mode for a cellular connection. The method is performed at a device that is configured to establish a network connection to a network. The method includes detecting a number of at least one event that has occurred over a time period, the at least one event associated with operations used through the network connection, the at least one event indicative of a power to perform the operations that is greater than a predetermined power. When the number is at least a predetermined threshold, the method includes identifying the network connection as being in a high power state. The method includes activating settings when the network connection is in the high power state, the settings reducing a usage of the operations over the network connection.

Abstract: An approach is described for a wireless device comprising a transceiver and a processor communicatively coupled to the transceiver. In a thread-based device, a thread radio coexists with a primary radio, such as a Bluetooth or WiFi radio. Because both radio share a common frequency band, the thread radio requests grants from the primary radio for transmission and reception. So as to avoid bogging down the primary radio, the thread radio throttles its requests. Specifically, the thread radio tracks certain variables indicative of the number of requests that have been made within a time window and the types of requests that have been made to the primary radio. By limiting the number of total requests and the number of requests of each type within the time window, the thread radio avoids overburdening the primary radio.

Abstract: An approach is described for a wireless device comprising a transceiver and a processor communicatively coupled to the transceiver. The processor is configured to detect a packet for transmission; scan, using the transceiver, a channel during an initial sliding window, the initial sliding window having N symbol durations; determine a power distribution of the initial sliding window based on the channel scan; determine that the channel is occupied during a first time period of the initial sliding window based at least on the power distribution; and determine a second sliding window having a second time period and a third time period. The second time period overlaps with the initial sliding window and a length of the third time period is determined based at least on the power distribution. The processor is further configured to scan, using the transceiver, the channel during the third time period; determine that the channel is idle during the third time period of the second sliding window; and transmit, using the transceiver, the packet to a second wireless device on the channel responsive to the third time period being idle.

Abstract: A method performed by a station that includes receiving information from a cell of a Public Land Mobile Network (PLMN), determining whether the information indicates the cell supports circuit switched fallback (CSFB) voice calls, when the CSFB voice calls are not supported, determining whether at least one packet switched voice property of the station satisfies a predetermined condition and attaching to the cell of the PLMN when the predetermined condition is satisfied. A further method performed by a station connected to a PLMN that includes identifying cells of the PLMN available for the station to camp on, determining whether the station is capable of executing packet switched calls, when the station is not capable of executing packet switched calls, determining whether the identified cells have a neighbor cell that supports CSFB voice calls and prioritizing the cells that are identified as having neighbor cells that support CSFB voice calls.

Abstract: Described herein are apparatus, systems and methods for improved mobility between wireless networks. A method may comprise, at a user equipment (“UE”) in communication with a cellular network activating a detach timer for the cellular network, detecting a short-range network, communicating with the short-range network, storing registration and bearer context data related to the cellular network, interrupting communication with the cellular network, and prior to the expiration of the detach timer, reconnecting to the cellular network via a service request without using an attach procedure.

Abstract: Apparatus and methods for estimating data traffic characteristics for applications to condition data communication channels that support data packet transfer for the applications in wireless communication devices are disclosed. Data connections to support different applications and/or daemon software processes can be established and subsequently adjusted based on data traffic characteristics for data that the different applications/daemons generate and/or consume. Traffic flows for the applications/daemons are classified into traffic classes based on likely data traffic patterns. When data sources are added or deleted, changes to a traffic class state can be determined, and wireless circuitry adjusted based at least in part on the traffic class state and a traffic class policy. Adjusting parameters that affect the periodicity and/or length of active time periods and sleep periods in accordance with estimated data traffic patterns for applications/daemons that use the data connections can reduce power consumption by the wireless circuitry.

Abstract: Methods, devices, and apparatus to adapt operating parameters for satellite signal reception and transmission by a wireless device to mitigate effects of fading due to specular reflections are described herein. The wireless device measures received signal power levels and compares characteristics of the measurements over an observation duration to at least one fading criteria to determine whether to operate in a normal or adaptive mode. While operating in the adaptive mode, the wireless device alternates between high performance mode time periods and low performance mode time periods. The wireless device indicates to a ground station associated with the satellite in which operating mode the wireless device is operating via an uplink data message transmitted during a data cycle at the start of a high or low performance mode time period. The ground station schedules data transmissions accordingly during subsequent data cycles of the high or low performance mode time periods.
