Multiple successive time slots are allocable upon which to communicate data to a receiving communication station. At selected intervals, a controller causes the mode of operation of the receiving communication station to be changed to pause operation in a receive mode and, during the pause, to cause operation of the receiving communication station to transmit data, such as control acknowledgments or other responses.

Abstract: A system and method are disclosed for managing the wireless delivery of streaming media content to a user equipment (UE) device. A UE device establishes a network connection with a local wireless network, which in turn is associated with a wireless network region with a corresponding data infrastructure server. The UE device then requests predetermined streaming media content from the data infrastructure server. A determination is made whether the requested streaming media content is stored in transcoded form on the data infrastructure server. If so, then a control information network is implemented to transmit and receive streaming media content control data between the UE device and the data infrastructure server. In turn, the streaming media content control data is used by the data infrastructure server to control the transmission of the transcoded streaming media content over a data network for delivery to the UE device.

Abstract: A system and method are disclosed for managing the wireless delivery of streaming media content to a user equipment (UE) device. A UE device establishes a network connection with a local wireless network, which in turn is associated with a wireless network region with a corresponding data infrastructure server. The UE device then requests predetermined streaming media content from the data infrastructure server. A determination is made whether the requested streaming media content is stored in transcoded form on the data infrastructure server. If so, then a control information network is implemented to transmit and receive streaming media content control data between the UE device and the data infrastructure server. In turn, the streaming media content control data is used by the data infrastructure server to control the transmission of the transcoded streaming media content over a data network for delivery to the UE device.

Abstract: An electronic device with multiple user interfaces configured such that more than one interface ambiguously responds to a user gesture intended as input to the device. To remove ambiguity, the device may operate in one of a plurality of input modes, in which outputs of different ones of the user interfaces are selectively processed. The user input mode may be specified by a user such that the device unambiguously responds to a gesture as intended. The device may be a portable electronic device with closely spaced user interfaces that each respond to a user gesture near the device. The device may be a portable electronic device with non-contact sensors that detect a user gesture in a three dimensional space above a surface of the device. Such a device may distinguish such gestures, intended as navigational information, from gestures associated with location-based or other types of inputs.

In some implementations, the wireless network operator denies the disapproved mobile device applications access to the wireless network resources. In some implementations, mobile devices disable access to the wireless network by the disapproved mobile device applications.
