System and method for bypassing an access point in a local area network for P2P data transfers
First Claim
1. A method comprising:
- establishing a primary wireless communication link with an access point of a wireless LAN at a first device having a cross-layer implementation with a primary local wireless interface associated with a network agent and a secondary wireless interface associated with a network agent;
determining if a second device is within a local wireless coverage area of the first device;
establishing the direct secondary wireless communication link with the secondary local wireless interface between the first device and the second device when the second device is within the local wireless coverage area of the first device, wherein a cross-layer agent of the first device receives information from one of the primary local wireless interface network agent and the secondary wireless interface network agent and causes a protocol stack switch of the first device to facilitate establishing the direct secondary wireless communication link via a secondary local wireless interface transport layer of the secondary wireless interface; and
transferring data between the first device and the second device over the secondary wireless communication link.

Abstract
A system and method for bypassing an access point in a wireless Local Area Network (LAN) for direct point-to-point data transfers are provided. A user device in the wireless LAN is equipped with a primary local wireless interface establishing a wireless communication link with an access point of the wireless LAN, a secondary local wireless interface used for direct point-to-point (P2P) file transfers, and a P2P file transfer application. When the P2P application desires to transfer a data file to another user device within the wireless LAN, the user device determines whether the other user device is within a coverage area of the secondary local wireless interface and whether the file transfer meets one or more alternate transfer criterion. If so, the data file is transferred to the other user device via a direct P2P wireless communication link, thereby bypassing the access point of the wireless LAN.
