Extending memory capacity of a mobile device using proximate devices and multicasting
First Claim
1. A method for downloading a file by a data processing system comprising a data processor and a memory, comprising steps of:
- the data processing system receiving device properties associated with each device of a plurality of devices;
the data processing system partitioning the file into a plurality of file extents based upon the device properties that are associated with the each device and received by the data processing system;
the data processing system establishing a communication session with a single one of the plurality of devices; and
the data processing system sending the plurality of file extents to the single one of the plurality of devices, wherein available memory in the single one of the plurality of devices is less than an overall size of the file when the data processing system sends the plurality of file extents to the single one of the plurality of devices;
wherein the device properties associated with each device includes an amount of memory available for use within the each device, and wherein the file is partitioned into the plurality of file extents such that a size of a given file extent for a given device of the plurality of devices is less than or equal to the amount of memory available for use within the given device.

Abstract
An improved download capability for mobile devices, without requiring increasing of the local memory of such devices, by providing a set of multimedia devices with the capability to create a cooperative download grid where multiple instrumented devices can be aggregated together according to predefined profiles. This capability is useful in at least two different scenarios. The first is when a SIP enabled device must download a large file having a capacity that is larger than the available memory of the SIP device. The second is when a SIP enabled device must download a file but cannot be connected for a long enough time to accomplish the download. If the SIP device is in proximity to other compatible devices such as Voice over Internet Protocol (VoIP) or Session Initiation Protocol (SIP), these devices are operable to be dynamically aggregated to provide a download grid with multiprotocol support that allows optimized downloading.

11. A method for downloading a file by a data processing system comprising a data processor and a memory, comprising steps of:
-
receiving, at the data processing system, device properties associated with a device; establishing a communication session with the device to form a communication session; receiving, by the data processing system, a first portion of the file; and sending, by the data processing system, the first portion of the file to the device while receiving another portion of the file at the data processing system, wherein the data processing system is a portable device, and further comprising; transmitting the device properties to a server application across a network, wherein available memory in the data processing system is less than an overall size of the file when the data processing system downloads the file. - View Dependent Claims (12, 13, 14, 15)
