Abstract

A method and system identifies a data file for transfer to a user. The invention also detects the movement of the user device from which the data file transfer was made and calculates a projected path for movement of the user device. Based on the projected path of movement, the sections of the requested data file are transferred in parallel to node areas where the user device is projected to move according to the projected path. As the user enters a node area, the section of the data file downloaded to that node area is locally transferred to the user device and thereby substantially reducing download time of a large data file.

Claims

1. A method for optimizing large file transfers while moving through nodes on a wireless network comprising:

receiving a data request at a network core from a mobile cellular device;

identifying and locating data of the received data request;

determining whether the mobile cellular device making the request is moving;

when the determination is that the mobile cellular device is moving, projecting a path for which the mobile cellular device will move;

identifying node areas through which the mobile cellular device will travel based on the projected path;

calculating and dividing a data file into sections of various sizes for download to each identified node area based on the projected movement path of the mobile cellular device and download speed of the data file to the mobile device.

2. The method for optimizing large file transfers as described in claim 1 further comprising before said determining whether the mobile cellular device making the request is moving, determining a load volume at a receiving node where the data request was mode.

3. The method for optimizing large file transfers as described in claim 2 further comprising after said determining a load volume at a node where the data request was mode, determining load capacity at the receiving node.

4. The method for optimizing large file transfers as described in claim 3 further comprising after said projecting a path for which the mobile cellular device will move, determining whether the projected path the mobile cellular device will take the mobile cellular device out of the area of the receiving node.

5. The method for optimizing large file transfers as described in claim 1 further comprising before said determining sections of a data file for download to each identified node area, calculating a total download time for the requested data.

6. The method for optimizing large file transfers as described in claim 5 further comprising determining download speed at a current node and at a future node in order to determine download time.

7. The method for optimizing large file transfers as described in claim 6 further comprising adjusting a current download speed of the mobile cellular device at the requesting node based on determined download speed at a current node and at a future node.

8. A method for optimizing large file transfers while moving through nodes on a wireless network comprising:

receiving a data request at a network core from a mobile cellular device;

identifying the mobile cellular device from which the data request was received;

identifying and locating data of the received data request;

identifying a location of a tower of a node location for the requesting mobile cellular device;

determining if a load sharing process can be implemented at the node location for the requesting mobile cellular device;

when the determination is that a load sharing process can be implemented, calculating download speeds for various data files being downloaded at the for the requesting mobile cellular device; and

adjusting download speeds for one or more of the various files being downloaded at the node for the requesting mobile cellular device.

9. The method for optimizing large file transfers as described in claim 8 further comprising before said determination if load sharing can be implemented, detecting movement of the requesting mobile cellular device in the node area of the requesting device.

10. The method for optimizing large file transfers as described in claim 9 further comprising when movement of the requesting mobile device is detected, projecting a future movement and path of the requesting mobile device.

11. The method for optimizing large file transfers as described in claim 8 further comprising detecting movement of various devices downloading files in the node area and projecting a future movements of mobile devices for which movements are detected.

12. The method for optimizing large file transfers as described in claim 11 further comprising determining if detected movements of various devices downloading files in the node area takes a devices out of the node area.

13. The method for optimizing large file transfers as described in claim 12 of various devices downloading files in the node area further comprising:

determining a projected load at the projected tower of the node; and

adjusting download speeds for one or more of the various files being downloaded at the node for the requesting mobile cellular device.
