  • Patent number: 11419054
    Abstract: Energy consumption of cellular interfaces on multihomed mobile devices, such as smartphones, tablets and laptops can be improved by adjusting the inactivity timer of the cellular interface of the mobile devices based on the on/off status of non-cellular interface(s) on the mobile devices. Possible near-future data packets can be transmitted or received on the non-cellular interfaces that co-exist on the mobile devices and thus the inactivity timer of the cellular interface may be dynamically and more efficiently adjusted, based on the on/off status of non-cellular interface(s). If the non-cellular interface is available on the mobile device, then the inactivity timer can be set to be shorter than if only the cellular interface is available.

  • Patent number: 11341498
    Abstract: The present invention provides methods and apparatuses for verifying that a transaction is legitimate. The methods and apparatuses use protected memory space, such as kernel space of an operating system, or a separate memory space, such as is available on a SIM card of a cellular phone. The method of the invention proceeds by creating a transaction identification string (TID) and associating the TID with a transaction. The TID contains data relevant to or associated with the transaction and is typically readable by an end-user. The transaction is then interrupted until a user responds in the affirmative to allow completion of the transaction. Methods and devices used in the invention are particularly well suited to M-commerce, where transactions originating from a device are typically recognized by a merchant as coming from the owner of the device without further authentication.

  • Patent number: 11206706
    Abstract: In one example, a method and apparatus for web browsing on multihomed mobile devices having multiple communication interfaces are disclosed. In one example, the method establishes a primary multiple path transmission control protocol subflow for the transfer of a resource from a server to a user endpoint device. The method then determines a threshold of resource size. When the size of the resource is determined to exceed the threshold, the method establishes a secondary multipath transmission control protocol connection that cooperates with the primary multiple path transmission control protocol subflow for the transfer of the resource from the server to the user endpoint device.

  • Patent number: 11206332
    Abstract: A pre-distortion system for improved mobile device communications via cancellation of nonlinear distortion is disclosed. The pre-distortion system may transmit an acoustic signal from a network to a device, wherein the acoustic signal includes a linear signal and a nonlinear cancellation signal that cancels at least a portion of nonlinear distortions created once a loudspeaker in the device emits the linear signal. Thus, when a loudspeaker of a mobile device is operating and nonlinear distortions are generated by the loudspeaker or adjacent components of the mobile device in close proximity to the loudspeaker, the pre-distortion system may create one or more nonlinear cancellation signals in the network. The nonlinear cancellation signal may be combined with the linear signal sent to the loudspeaker to cancel the nonlinear distortion signal created by the loudspeaker emitting acoustic sounds from the linear signal. Thus, the nonlinear cancellation signal becomes a pre-distortion signal.

  • Patent number: 11031027
    Abstract: A system for providing an acoustic environment recognizer for optimal speech processing is disclosed. In particular, the system may utilize metadata obtained from various acoustic environments to assist in suppressing ambient noise interfering with a desired audio signal. In order to do so, the system may receive an audio stream including an audio signal associated with a user and including ambient noise obtained from an acoustic environment of the user. The system may obtain first metadata associated with the ambient noise, and may determine if the first metadata corresponds to second metadata in a profile for the acoustic environment. If the first metadata corresponds to the second metadata, the system may select a processing scheme for suppressing the ambient noise from the audio stream, and process the audio stream using the processing scheme. Once the audio stream is processed, the system may provide the audio stream to a destination.

  • Patent number: 11026144
    Abstract: Improved non-cellular (e.g., Wi-Fi) link integration with a cellular (e.g., LTE) network is described. The improved link integration can relate to utilizing an eNodeB device (e.g., residing in a radio access network portion of a cellular network) as an anchor point rather than a packet data network gateway device (e.g., residing in a core network portion of the cellular network) utilized by other approaches. The improved link integration can maintain full compliance with or support for other approaches, and can reduce signaling overhead, simplify quality-of-service management, and/or provide a more rapid reaction to changes of access, particularly in cases where the eNodeB device and a non-cellular access point device are co-located.
