Abstract

Techniques are presented herein to allow a user to distribute the downloading of a file over a high cost medium among multiple devices in an ad-hoc group. The downloaded chunks/portions are transferred via a high speed lower cost medium to the requesting device for reassembly. This allows mobile data users to avoid additional charges associated with mobile data transfer limits.

ABSTRACT

    Techniques are presented herein to allow a user to distribute the downloading of a file over a high cost medium among multiple devices in an ad-hoc group. The downloaded chunks/portions are transferred via a high speed lower cost medium to the requesting device for reassembly. This allows mobile data users to avoid additional charges associated with mobile data transfer limits.

DETAILED DESCRIPTION

    Mobile data users are limited by the data transfer rate of their device. They also may be limited in the amount of data that they can download per month. Mobile data users do not have any way of increasing their download speed or decreasing their bandwidth usage without paying for a higher tier data connection.

    A solution is presented herein that allows a user to distribute the downloading of a file over a high cost medium among devices in an ad-hoc group. The downloaded chunks of data are transferred via a high speed, lower cost medium to the requesting device. The requesting device will then combine the chunks to form the desired file. This solution reduces the time required to download the file, as well as decreases the bandwidth utilization over a higher cost medium for each individual device (if the device users were to download the file on their own).

    The figure below illustrates a flow of how the solution works for a group of 3 users (UserA, UserB and UserC), with UserA wanting to download a 3GB file using a 3G cellular network, and combining the file using a low cost high speed Bluetooth┬« wireless link.

    In the example shown in the figure above, UserA wants to download a 3GB file in a room with 2 other friends. While on a 3G wireless cellular connection UserA sends a request to nearby users: UserB and UserC. This request can be over any medium, e.g., Near Field Communication (NFC), Bluetooth, Wi-Fi┬«, 3G, LTE, etc.

Nearby UserB and UserC receive the request.

    UserB and UserC respond if they accept the request to join the ad-hoc downloading group. The responses from UserB and UserC include the file size amount
