  • Publication number: 20190281411
    Abstract: Embodiments of this application disclose an interaction information obtaining method performed at a target user terminal. After detecting, on a virtual map preset in an interaction application, a trigger operation performed on a target POI identifier, the target user terminal obtains first location information of the target user terminal by using the virtual map and second location information corresponding to the target POI identifier on the virtual map. The target user terminal detects a distance difference between the first location information and the second location information. When the distance difference satisfies a preset distance range, the target user terminal sends, to an interaction server, an interaction information request carrying the target POI identifier and receives interaction information corresponding to the target POI identifier from the interaction server and then displays the interaction information on the virtual map.

  • Publication number: 20190278419
    Abstract: A method and a system for reducing current noise of a touch terminal are provided. The method includes: determining that a user receives a voice call via an earpiece of the touch terminal, and controlling the touch terminal to switch from a first touch scan frequency to a second touch scan frequency, where the second touch scan frequency is less than the first touch scan frequency. As can be seen, if the user receives the voice call via the earpiece of the touch terminal, the touch terminal is controlled to switch from the first touch scan frequency to the second touch scan frequency, to effectively reduce the current noise heard by the user by decreasing the touch scan frequency of the touch terminal, so that the periodic current noise is outside a frequency band perceptible to a human ear, thereby improving user experience when receiving the voice call.

  • Publication number: 20190281292
    Abstract: A method for intra prediction mode decoding for a current block based on multi-level most probable mode (MPM) sets. The method includes determining one or more MPM candidates for a first-level MPM set, and determining one or more most probable remaining mode (MPRM) candidates for a second-level MPM set. Wherein the one or more MPRM candidates are identified based on a mode of a neighboring block of the current block, and the one or more MPRM candidates are different from any MPM candidate in the first-level MPM set. The method also includes decoding syntax information related to a current intra prediction mode corresponding to the current block according to the multi-level MPM sets using a decoder, and decoding the current block based on the determined current intra prediction mode.

  • Patent number: 10362628
    Abstract: When machine-to-machine (M2M) devices attach to a mobile communication network, the associated communication session can be treated differently than the attachment of other devices. For example, upon determining that a subscriber device that attaches to a communication network is an M2M device and has completed a given network transaction, the M2M device can be immediately detached without waiting on expiration of an inactivity timer. As another example, upon determining that a subscriber device that attaches to a communication network is an M2M device, the M2M device can be excluded from various signaling procedures such as load-balancing procedures.
