A document management apparatus includes a first transmitting unit, a determination unit, and a second transmitting unit. The first transmitting unit transmits a first document to a terminal apparatus in response to a request from the terminal apparatus. The determination unit determines, based on a period of time for which it is predicted that communication between the terminal apparatus and the document management apparatus is disabled, a second document which is related to the first document. The second transmitting unit transmits the second document to the terminal apparatus.

A client and content provider are connected by a plurality of simultaneous transport connections. The number of the transport connections that are used to transfer data is selected based on the size of the data to be transferred and may change after transfer of data has commenced based on the amount of data left and the attributes of the transport connections. In another aspect, data to be transmitted over the transport connections is organized into frames such that each frame includes data from only one data stream. The frames are sized to be less than or equal to a control window of the transport connection over which they are transmitted. Each frame may be assigned to a transport connection in a round robin fashion or based on the size of the frame and the sizes of the control windows of the transport connections.

In some implementations, a user device can personalize a media stream by converting notifications into audio speech data and presenting the audio speech data at locations within the media stream that do not interrupt the enjoyment of the media stream by the user. In some implementations, the user device can receive notifications from various communication services, applications installed on the user device, and/or other sources, determine information describing the notifications, and present the information to the user using the audio speech data. In some implementations, the user device can generate personalized notifications based on the media stream and/or media items selected by the user. The user device can generate personalized notifications based on the user's context (e.g., environment, location, activity, etc.). The personalized notifications can then be presented to the user using audio speech data at appropriate locations in the media stream.

The present disclosure relates to technologies for a sensor network, machine-to-machine (M2M) communications, or machine type communications (MTC), and Internet of things (IoT), and may be utilized in intelligent services, based on the above technologies, such as a smart home, a smart building, smart cities, smart cars or connected cars, smart grids, healthcare, smart electronics, advanced medical services, public safety network communications through fusion and convergence with conventional IT technologies and various industries. Data transmission control between a group of uncoordinated electronic devices in a computer network including the use of transmission authorization request messages and transmission authorization grant messages.

When a portable information terminal operates in an unused state, a predetermined access point is searched for. As a result, when the predetermined access point is detected, a connection to the predetermined access point is established, and a predetermined data communication process is performed.

An aspect of the present disclosure facilitates selection of leader nodes in distributed data services. In one embodiment, a distributed data service is provided operative based on multiple nodes. Upon receiving from a user a selection of a set of nodes that are preferred as leader nodes, a node contained in the set of nodes is set as a leader node in the distributed data service in view of the selection by the user. Accordingly, a user is provided control over the selection of leader nodes in the distributed data service.

A method, device and system for carrying out telecommunication capability group sending is provided, each node of a system for carrying out telecommunication capability group sending corresponds to a database service node, a plurality of database service nodes perform load balancing or switching on failure within themselves and each node of the system for carrying out telecommunication capability group sending may quickly read the subscription relationships and send down messages to users. The above technical solution increases the database access speed and avoids the problem of database's resources shortage and improves service performance of the telecommunication capability group sending.

Systems and methods for selecting content based on an event associated with a device identifier are provided. One or more processors can receive a request to serve content. The processors can identify a device identifier associated with the request. The processors can determine, from the device identifier, an event for which to serve content. The processors can determine, from the request, a length of time between a time the request to serve content is received and a time at which the event is scheduled to occur. The processors can select, based on the determined length of time and event parameters associated with the event, content for display and provide the selected content for display at a computing device associated with the device identifier.

Methods and systems for improving data back-up, recovery, and search across different cloud-based applications, services, and platforms are described. A data management and storage system may direct compute and storage resources within a customer's cloud-based data storage account to back-up and restore data while the customer retains full control of their data. The data management and storage system may direct the compute and storage resources within the customer's cloud-based data storage account to generate and store secondary layers that are used for generating search indexes, to generate and store shared space layers and user specific layers to facilitate the deduplication of email attachments and text blocks, to perform a controlled restoration of email snapshots such that sensitive information (e.g., restricted keywords) located within stored snapshots remains protected, and to detect and preserve emails that were received or transmitted and then deleted between two consecutive snapshots.
