Abstract: A user device includes an interface and one or more processors. The interface is configured to communicate over a network. The one or more processors are configured to evaluate a pre-load scheduling condition with respect to a user application installed in the user device, and to schedule pre-loading of the user application depending on the pre-load scheduling condition.

Abstract: A user device includes an interface and one or more processors. The interface is configured to communicate over a network. The one or more processors are configured to evaluate a pre-load scheduling condition with respect to a user application installed in the user device, and to schedule pre-loading of the user application depending on the pre-load scheduling condition.

Abstract: A method includes, in a user device (24) that runs an Operating System (OS-48), deciding to preload at least a User-Interface (UI) display of a user application (26). At least the UI display is preloaded in a simulated-foreground mode in which the UI display is (i) processed in a foreground mode by the user application, but (ii) kept in a background mode by the OS and hidden from a user of the user device.

Abstract: A user device includes a memory and one or more processors. The memory is configured to store one or more user applications installed in the user device. The one or more processors are configured to run an Operating System (OS) of the user device, including maintaining a data structure that tracks activity of the user applications, and to pre-load a user application before the user application is accessed by a user, including preventing the data structure from tracking the pre-loaded user application.

Abstract: A user device includes a memory and one or more processors. The memory is configured to store one or more user applications installed in the user device. The one or more processors are configured to select one or more operations, which are to be performed in normal launching of a user application but not in background pre-loading of the user application, to pre-load the user application before the user application is accessed by a user, including skipping the one or more selected operations, and to complete the one or more skipped operations in response to the user accessing the user application.

Abstract: A user device includes a display screen and one or more processors. The display screen is configured to display content to a user. The one or more processors are configured to pre-load a user application by running at least part of a program code of the user application in a background, including enabling the program code of the user application to pre-render a visual display of the user application in the background, and, in response to the user accessing the user application, to transfer the pre-rendered visual display to a foreground, thereby displaying the visual display to the user on the display screen.

Abstract: A system (20) includes one or more interfaces and multiple processors. The one or more interfaces are configured to communicate over a communication network (40). At least a first processor from among the processors is included in a user device (24) and at least a second processor from among the processors is included in a server (52) external to the user device. The processors are configured to track content items that are provided by one or more content sources (36) and to deliver the content items to one or more applications (32) installed in the user device.

Abstract: An apparatus (24, 60) includes a network interface (64) and one or more processors (44, 68). The network interface is configured for communicating over a communication network (32). The one or more processors are configured to prefetch content items over the communication network, from a content source (28) to a cache memory (52) of a user device (24), wherein at least a content item among the content items includes a cache directive specified by the content source, to modify the cache directive specified by the content source, and to serve the content item having the modified cache directive to a user application (36) running in the user device, so as to cause the user application to process the content item responsively to the modified cache directive.

Abstract: A system includes a network interface and one or more processors. The processors are configured to track a first pattern with which a user terminal consumes one or more data services while served by a home network specified for the user terminal, to track a second pattern with which the user terminal consumes the one or more data services while served by one or more networks other than the home network, to estimate a reduction in usage of the one or more data services between the first and second patterns, and to selectively enable at least one data service to the user terminal by the networks other than the home network, based on the estimated reduction in usage.
