SYSTEMS AND METHODS FOR TRANSPORTING DATA ACROSS AN AIR INTERFACE USING REDUCED ADDRESS HEADERS

摘要

Systems and methods are disclosed for transporting data across an air interface using a blending of protocol layers to achieve reduced bandwidth. Advantage is taken of the fact that the extra overhead from, for example, the Ethernet protocol is addressing information pertaining to the destination of the packet. This destination information (for example, the Ethernet address) can be stripped from the transmission prior to the air interface and recreated after the air interface. In one embodiment, the concepts of a proper Layer 2 CS are merged on top of the 802.16 protocol and still retain the benefits of a Layer 2 transparent bridged service layer to the network layer. In one embodiment, the MAC address of the destination is used for the air interface and the Ethernet address is recreated and added on the far side of the air interface.

主权项

1. A method for delivering data packets across an air interface, said method comprising:
receiving a data packet at a first physical location on one side of said air interface, said packet having a destination location bearing a specific LAN address in addition to its network address, wherein said packet contains said specific LAN address of said destination location; and transmitting said packet across said air interface without said specific LAN address, said specific LAN address being added at a second physical location to said data packet using at least one look-up table keyed to said specific LAN address; wherein said added LAN address is derived at least in part from an IP convergence sub-layer (IP-CS) information contained in said packet and at least in part from information stored at said second location for delivering said transmitted packet to said destination location; wherein said packet is received across said air interface at said second physical location, said destination location determined, at least in part, from other information contained within said packet and at least in part from said information stored at said second physical location; and wherein said first physical location removes said LAN address from said packet prior to said transmitting said packet across said air interface.
