Abstract

A system and method of managing the bandwidth of transmitted communications in a wireless network where a data packet (108) is received. The data packet (108) comprises a protocol identifier (110). At least one primary pattern identifier (110) is stored in a memory (103). The protocol identifier (110) is compared (204, 206) to the at least one primary pattern identifier and a data packet type is determined (210) based at least in part upon the comparing. A resource allocation scheme is selected from amongst a plurality of resource allocation schemes for application to a wireless network based at least in part upon the data packet type.

Claims

1. A method of managing bandwidth of transmitted communications in a wireless network comprising:

receiving a data packet, the data packet comprising a protocol identifier;

comparing the protocol identifier to at least one primary pattern identifier;

determining a data packet type based at least in part upon the comparing; and

selecting a resource allocation scheme from amongst a plurality of resource allocation schemes for application to a wireless network based at least in part upon the data packet type.

2. The method of claim 1, wherein the comparing further comprises comparing the protocol identifier to at least one secondary pattern when the profile identifier matches the at least one primary pattern identifier.

3. The method of claim 1 further comprising applying the resource allocation scheme to the network.

4. The method of claim 3 wherein applying the resource allocation scheme further comprises using the resource allocation scheme to adjust resources selected from a group comprising controllable RF parameters and physical resources.

5. The method of claim 4 wherein using the resource allocation scheme comprises adjusting physical resources selected from a group comprising a memory, a CPU, and backhaul bandwidth in a RAN.

6. The method of claim 1 further comprising applying a default resource allocation scheme when the comparing determines no matches.

7. The method of claim 1 wherein the selecting the resource allocation scheme comprises determining a scheduler algorithm and a data rate.

8. The method of claim 1 further comprising periodically monitoring changes in the payload and adjusting the scheduler and resources based upon the changes.

9. The method of claim 1 wherein the selecting the resource allocation scheme comprises determining a scheduler algorithm, a data rate, and a number of resources.

10. A scheduling device for facilitating efficient communications in a wireless network comprising:

a receiver having an input that receives a data packet, the data packet comprising a protocol identifier;

a memory having at least one primary pattern identifier stored therein;

a controller coupled to the input of the receiver and the memory, the controller programmed to compare the protocol identifier with the at least one primary pattern stored in the memory, the controller further programmed to determine a data packet type based at least in part upon whether the protocol identifier sufficiently matches the at least one stored primary pattern identifier and, responsively, selecting a resource allocation scheme.

11. The device of claim 10 wherein the controller further comprises an output and wherein the resource allocation scheme is transmitted via the output.

12. The device of claim 10 wherein the controller further comprises means for selecting a default resource allocation scheme when no match is detected between the identifier and the at least one stored primary pattern identifier.

13. The device of claim 10 wherein the resource allocation scheme comprises a scheduling algorithm, number of resources, and data rate.

14. The device of claim 10 wherein the controller is further programmed to attempt to match at least one secondary pattern stored in the memory to the protocol identifier.

15. The device of claim 10 wherein the at least one primary pattern identifier is programmed into the memory by an operator.

16. The device of claim 10 wherein a payload of the data packet comprises a Point-to-Point Protocol (PPP) header.

17. The device of claim 10 wherein the data packet type is selected from a group comprising a Link Control Protocol (LCP) configuration request, an Internet Protocol (IP) traffic data packet, a Session Initiation Protocol (SIP) request, and a HyperText Transfer Protocol (HTTP) request.

18. The device of claim 10 wherein the controller is programmed to identify primary and secondary patterns in the data packets.

19. The device of claim 18 wherein the device operates within configurable thresholds and wherein the thresholds are adjusted to alternative settings when a demand of the thresholds is not met.

20. The device of claim 10 wherein controller is further programmed to independently adjust resource allocation, fairness, and priority for multiple users, applications, and sessions.
