Abstract
A method performed by a device that has a current first network connection to a first network. The device determining one or more current conditions associated with the device, determining whether a disconnect of the first network connection is imminent based on the one or more current conditions and responsive to determining that the disconnect is imminent, performing a pre-fetch operation to request data over the first network connection for at least one application resident on the device.
Claims20
A method, comprising:
- at a device that has a current first network connection to a first network:
- determining a context of the device based on at least one of a change in position of the device or a relative position of the device;
- determining a quality of the first network connection based on a measured parameter of the first network connection;
- determining whether a disconnect of the first network connection is imminent based on the quality of the first network connection and the context of the device;
- and
- responsive to determining that the disconnect is imminent, performing a pre-fetch operation to request data over the first network connection for at least one application resident on the device, wherein increments of data to be pre-fetched in the pre-fetch operation is based on the quality of the first network connection.

A device, comprising:
- a transceiver configured to establish a first network connection to a first network;
- and
- a processor configured to determine a quality of the first network and a context of the device, wherein the quality comprises a measured parameter of the first network connection and the context of the device comprises at least one of a change in position of the device or a relative position of the device, the processor being further configured to determine whether a disconnect of the first network connection is imminent based on the quality of the first network connection and the context of the device, wherein determining whether the disconnect is imminent comprises, comparing the measured parameter to a first threshold, comparing the change in position of the device or relative position of the device to a second threshold, wherein the disconnect is imminent when the measured parameter satisfies the first threshold and the change in position satisfies the second threshold, determined to be imminent, the processor being further configured to perform a pre-fetch operation to request data over the first network connection for at least one application executing on the device.
A processor configured to perform operations comprising:
- determining a quality of a first network connection and a context of the device, wherein the quality comprises a measured parameter of the first network connection and the context of the device comprises at least one of a change in position of the device or a relative position of the device;
- determining whether a disconnect of the first network connection is imminent based on the quality of the first network connection and the context of the device, wherein determining whether the disconnect is imminent comprises,
- comparing the measured parameter to a first threshold;
- and
- responsive to determining that the disconnect of the first network connection is imminent, performing a pre-fetch operation to request data over the first network connection for at least one application executing on the device, wherein increments of data to be pre-fetched in the pre-fetch operation is based on the quality of the first network connection.
