  • Patent number: 10264084
    Abstract: Some implementations allow users to create and share data including playlists. Such playlists may be subscribed to by other users. Changes to such playlists, such as updates by the curator of the playlist, must be propagated to subscribers in a timely manner while efficiently utilizing resources. Some implementations allow updates to be propagated using a push notification to cause client devices to request the update (push). Alternatively, updates may be made when the client devices of the subscribers next accesses the system (pull). An aggregator system may be used to make decisions on which users to send push notifications, and which users to wait to pull updates on their own. Additionally, the aggregator may determine that certain playlist updates should be distributed using push notifications. The aggregator may determine that only certain playlist subscribers should receive push notifications regarding playlist updates.

  • Patent number: 10206124
    Abstract: Many applications used in communication systems involve bidirectional data transfer. In bidirectional data transfer applications, a client terminal has to turn on its hardware components such as transmitter at the time of transmitting the data and the receiver at the time of receiving the data. When the transmission and reception of data happens at different time instances, the client terminal has to turn on and off the transmitter, the receiver and other modules at separate time instances. This may lead to increased power consumption. A method and apparatus are disclosed for the modem in a client terminal that bring the transmission and the reception instances close to each other or overlap with each other when performing bidirectional communication. This may reduce the rate at which the client terminal has to turn on and off its transmitter, receiver and other modules which may in turn reduce its power consumption.

  • Patent number: 10091467
    Abstract: In a battery-powered audio/video recording and communication device having a camera, the length of a preset interval (the interval between instances of the device sending a request to a network to check whether any user requests to access the camera have been received) may be adjusted upward or downward in order to balance the competing interests of reducing latency (e.g. reducing the delay that the user may experience when trying to access the camera) and conserving battery life. The present embodiments advantageously balance these competing interests by initially setting the length of the preset interval to be relatively short to reduce latency, but automatically increasing the length of the preset interval as the battery charge is depleted, thereby extending battery life. The present embodiments also advantageously enable the length of the preset interval to be increased after the battery is recharged, thereby reducing latency.

  • Patent number: 10085233
    Abstract: Embodiments herein provide a method for determining PO by UEs in an eDRX cycle. The method includes determining PHs in the eDRX cycle based on estimated values of UE_ID_H and number of hyper-frames in the eDRX cycle. The method includes determining a first radio frame of PTW based on a determined value of NPTW and ieDRX. The method includes determining a last radio frame of PTW based on the first radio frame and length of the PTW. The method includes determining PFs in the PTW. The determination of PFs is based on the UE_ID. The method includes determining the POs, in each of the determined PFs, based on an index associated with each of the POs. The index associated with each PO is computed based on the UE_ID, number of frames available for paging in a DRX cycle, and number of sub-frames available for paging in each PF.

  • Patent number: 10075199
    Abstract: Disclosed herein are front-end architectures for wireless communication that support a wide range of combinations of uplink carrier aggregation (UL CA) and simultaneous multiple-input multiple-output (MIMO) functionality. Embodiments can include a separate mid-band power amplifier module and a separate high band power amplifier module, and can establish various numbers of antenna outputs from these modules to connect to available diplexers or triplexers in selected ways to cover all intended use cases. Duplication of filters, duplexers, and/or quadplexers is reduced or minimized by re-using filtering in a selectively designed MIMO receive module that supports switch-combined TX filters. A UL CA power amplifier module makes use of the MIMO receive module, as well as the re-use of available filters in the mid-band primary power amplifier module.

  • Patent number: 10070388
    Abstract: In one aspect, a node in a mesh network receives presence messages from neighbor node in the mesh network, and determines a number of neighbor nodes, based on the received presence messages. The node determines a duty cycle percentage to be requested of the neighbor nodes, based on the number of the neighbor nodes, the duty cycle percentage indicating a minimum percentage of time the neighbor nodes should be awake to receive messages, so as to ensure a predetermined probability of successful reception of messages transmitted by the node. The node broadcasts the duty cycle percentage for reception by the neighbor nodes. The node also receives requested duty cycle percentages from corresponding neighbor nodes, sets an operating duty cycle of the node based on a greatest duty cycle percentage of the received duty cycle percentages, and sleeps and wakes according to the set duty cycle of the node.

  • Patent number: 10064026
    Abstract: A unified message delivery between multiple devices is disclosed. Sending messages through a local communications link, such as but not limited to at least one of a Bluetooth connection and a peer-to-peer WiFi connection, can lead to faster transmission times and reduced server load. When the local communications link is unavailable or not suitable, the messages can be sent through a network and a push server. In some examples, messages can be sent through both the local communications link and through the network and the push server. Duplicates of a received message can be avoided by utilizing indicators. In some examples, one or more devices can include queue(s) to ensure ordered delivery of a plurality of messages when a local communications link and network connection become unavailable.
