Embodiment Construction

[0027] Reference will now be made in detail to the exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0028] FIG. 4 illustrates a tunneling system 400 for overcoming the aforementioned shortcomings of a legacy frame structure. Referring to FIG. 4 , a tunnel identifier (T-CID) 402 is associated with a plurality of MPDUs 404 . MPDUs originate at base station 406 and travel through relay stations 408 , 410 and 412 . At relay station 412, MPDUs 404 are sent to their destination mobile users w (414), x (416), y (418) or z (420) depending on their CID 422, 424, 426 or 428.

[0029] There are a variety of tunneling modes that can be used with tunneling system 400 . One example is tunnel packet mode and another example is tunnel burst mode.

[0030] Figure 5AAn example of a tunneled packet mode frame 500 is ...

Abstract

A method for processing a frame received at a relay station in a wireless multi-hop relaying network, the frame including first control data in a header of the frame and second control data in a body of the frame includes examining the header of the frame to determine whether the first control data includes a tunnel identifier. The method also includes parsing the body of the frame if the first control data does not include the tunnel identifier, to retrieve the second control data, determining whether the second control data includes the tunnel identifier, classifying the frame by examining the contents of the first and second control data and forwarding the data frame.

Description

technical field [0001] The systems and methods disclosed herein relate to the field of mobile communications, and more specifically, to systems and methods for analyzing frames received at relay stations in wireless multi-hop relay networks. Background technique [0002] FIG. 1 illustrates a conventional wireless communication network 100 . Referring to FIG. 1, in a network 100, a base station 102 provides devices within a base station coverage area 104 with connectivity to a larger network (not shown). One or more mobile users 106 may receive wireless connectivity directly from base station 102 through one or more wireless connections. However, when network 100 has many mobile users 106 , base station 102 may not be able to handle the large number of wireless connections, which may cause communication delays and bottlenecks in network 100 . Therefore, in order to increase the throughput, the network 100 may also employ one or more relay stations 110 . Relay stations 110 ...
