  • Patent number: 11005900
    Abstract: A device state service supported on an application server is disclosed herein. The device state service is configured to dynamically monitor a device state across devices, and particularly monitor whether or not a device is currently active (e.g., incoming or outgoing ringing, incoming or outgoing busy signal, audio and/or video call in progress, etc.) The active device transmits device state data along with context data and sensor data (collectively “real-time data”). The inactive (or subject) devices may likewise transmit real-time data to the device state service. The device state service determines an action for the subject and/or active devices to perform based on the received real-time data. For example, when a user's smartphone is currently active (e.g., a call in-progress), the user's tablet may enter a power save mode to save resources.

  • Patent number: 10986634
    Abstract: Disclosed are methods and systems to facilitate management of carriers to help ensure QoS for single-carrier UEs. In particular, a base station may serve one or more first user equipment devices (UEs) on just a first carrier. While doing so, the base station may determine that each of the one or more first UEs being served on just the first carrier is receiving threshold low quality of service from the base station on the first carrier. Responsive to this determining, the base station may (i) select one or more second UEs based on the one or more second UEs being served by the base station on both the first carrier and one or more other carriers and (ii) discontinue serving each selected second UE on the first carrier while continuing to serve each selected second UE on one or more other carriers.

  • Patent number: 10951386
    Abstract: Aspects of the subject matter described herein are directed towards indicating to a wireless network device which time-division duplex slot patterns (slot formats) are supported by a user equipment device, e.g., which slot patterns have went through interoperability and deployment testing (IODT) successfully with respect to the type of user equipment device. With the supported slot pattern information, the network can make an intelligent decision on scheduling downlink/uplink ratios, while selecting a slot pattern that the user equipment device is known to support. In one aspect, the technology adds a “Slot format IODTed” information element in the user equipment device capability information, which the network obtains when the user equipment device reports its capabilities to the network. In another aspect, the network can query the user equipment device for the supported slot format information.

  • Patent number: 10925056
    Abstract: A SRLTE/Hybrid CDMA management system is provided to facilitate the prioritization and management of shared RF resources among the different SIMs and RATs in a multimode device. The described techniques address a shared single RF resource usage problem in multi-SIM and multimode 3GPP2/3GPP devices that implement an SRLTE or Hybrid CDMA mode in one or more SIMs. Thus, the techniques enable the RATs within an SRLTE or Hybrid CDMA system, and RATs across multiple SIMs, to access a single set of RF resources using a priority access scheme that prioritizes RATs for both packet service (PS) and circuit service (CS).

  • Patent number: 10925071
    Abstract: A method for adjusting the interference level for a wireless communication from a first mobile station to a second mobile station including detecting an interference level at a transmitting station and providing for elevation of the direction of beam for the signal transmissions from the first mobile station to the second mobile station relative to an angle between the ground plane and the current direction of beam for the transmissions from the first mobile station to the second mobile station. Such lifting up of the beam avoids interference at the place of a third mobile station located at the direction of signal transmission but with further distance, since the signal strength then vanishes relatively quickly if the beam is lifted up.

    Abstract: Methods and devices for synchronizing a device clock in a wireless network (e.g. a LPWAN) are disclosed. Example methods comprise identifying a device temperature, identifying a clock drift associated with the identified device temperature and applying a correction to the device clock based on the identified drift. For the identified device temperature, the drift is identified by comparing the confidence of the drift value in a pre-calibration curve generated from fixed drift values in a pre-calibration table with the confidence of the drift value in a learning curve generated from variable drift values in a learning table and selecting the drift value from the curve having the higher drift confidence.
